<<Schematic configuration of information processing system 1>>
An information processing system 1 shown in FIG. 1 includes an information collection system 2 and an information output system 3 . The information collection system 2 collects POI (Point of Interest) data by a predetermined method. The information output system 3 outputs POI data collected by the information collection system 2 . The POI data is data relating to POIs. A POI is a specific point on a map. A POI is, for example, a tourist spot.

The information collection system 2 of this embodiment collects POI data using SNS (Social networking service). The information collection system 2 has two or more information processing terminals 22 and an SNS server 23 . The information processing terminal 22 is a terminal device owned by two or more SNS users 21 . The SNS user 21 is a user of SNS. A terminal device is, for example, a mobile phone, a smart phone, a tablet, or a personal computer. The information collection system 2 may be configured to collect POI data by a method other than SNS.

The information collection system 2 can accumulate POI data collected from the information processing terminal 22 in the SNS server 23 . Hereinafter, the POI data transmitted or received between the information processing terminal 22 and the SNS server 23 will also be referred to as "first POI data". The first POI data is, for example, data relating to tourist spots. The first POI data is generated by the SNS user 21 . The first POI data includes POI position data, POI image data, and POI text data. The information processing terminal 22 acquires these data via a GPS (Global Positioning System), a camera, and an input device, none of which are shown in FIG. GPS obtains location data for POIs. The camera acquires image data of the POI. The input device acquires text data regarding the POI. The text data may be sentences containing words, word combinations, or subjects and predicates. In this embodiment, the text data indicates the name of the POI and the impression of the SNS user 21 on the POI.

In this embodiment, the SNS has a spreading function and an evaluation function. The diffusion function is a function that can diffuse the first POI data received by the information processing terminal 22 to the information processing terminals 22 owned by other SNS users 21 via the SNS server 23 . The spreading function is, for example, a retweet (RETWEET (registered trademark)) function of twitter (registered trademark). Other SNS users 21 can view the first POI data transmitted to their own information processing terminals 22 by the diffusion function. The evaluation function is a function that can evaluate the first POI data received by the information processing terminal 22 . The evaluation function includes, for example, the “Like” function of twitter (registered trademark). During use of the SNS, the information processing terminal 22 can display a "Like" button along with the first POI data. The SNS user 21 can press the "Like" button for the preferred first POI data.

The SNS server 23 provides the accumulated POI data to the information output system 3 . Specifically, the SNS server 23 provides the POI data to the database server 5 . In this embodiment, the SNS server 23 provides the accumulated first attribute data to the information output system 3 . The database server 5 provides POI data to the information processing terminal 4 . Hereinafter, the POI data for the database server 5 to transmit to the information processing terminal 4 will also be referred to as "second POI data".

The information output system 3 shown in FIG. 2 includes an information processing terminal 4 and a database server 5 . The information processing terminal 4 is a terminal device. The information processing terminal 4 is owned by each of two or more first users 31 and second users 34 shown in FIG. A first user 31 and a second user 34 are users of the information output system 3 . The first user 31 is a person who has used the information output system 3 to search for POIs in the past. The first user 31 is a person who has viewed or recorded the second POI data on the information processing terminal 4 using the information output system 3 . In the present embodiment, browsing means displaying the detailed information 83a of the second POI data shown in FIG. That is, the browsed second POI data indicates the POI in which the first user 31 is interested among the two or more POIs. Recording is, for example, bookmarking the second POI data. Bookmarking is a function of recording second POI data that is scheduled to be accessed frequently in the information processing terminal 4 . The second user 34 is a person who uses the information output system 3 to search for POIs to visit. A second user 34 is a future visitor to the POI. The information processing terminal 4 and the database server 5 are connected by wireless communication via a public communication network, for example.

In this embodiment, the information processing terminal 4 includes an input device 41 , a terminal communication device 42 , a display device 43 , a terminal control device 44 and a terminal storage device 49 . The terminal control device 44 includes a terminal communication control section 45 , a reference determination section 46 , a scale determination section 47 and a display control section 48 . The terminal control device 44 executes processing according to the program. The program includes an application for causing the information processing terminal 4 to output the second POI data acquired from the database server 5 . The second POI data is information about one or more POIs around the reference position. The reference position is, for example, the current location of the second user 34 . The second POI data includes POI position data, POI image data, and POI text data. The second POI data may further include display order information. The display order information indicates the display order. The display order is the order in which second POI data indicating two or more POIs are displayed on the display device 43 .

In this embodiment, the information output system 3 is configured to be able to set the attributes of the companions of the user. Specifically, the information output system 3 can set the attributes of the first companion 32 . The attributes of the first companion 32 are attributes set for the first user 31 . The attribute of the first companion 32 is the attribute of the companion of the first user 31 . The information output system 3 can also set attributes of the second companion 35 . The attributes of the second companion 35 are attributes set for the second user 34 . These attributes are, for example, the type of first companion 32 or second companion 35 . The attribute is, for example, the family or lover of the first user 31 or the second user 34 . The attribute may be, for example, None. That is, the attribute may be one first companion 32 or one second user 34 . Hereinafter, the attribute of the first companion 32 is described as "first attribute". Data indicating the first attribute is described as "first attribute data". The attribute of the second companion 35 is described as "second attribute". Data indicating the second attribute is described as "second attribute data". In this embodiment, the first attribute data and the second attribute data are transmitted from each information processing terminal 22 to the database server 5, respectively.

The database server 5 includes a server communication device 51 , a server control device 52 , a server storage device 56 and a database 57 . The server control device 52 includes a server communication control section 53 , a search section 54 and a ranking determination section 55 . When the second POI data is requested from the information processing terminal 4 by the operation of the second user 34, the database server 5 acquires the second POI data from the database 57, and sends the acquired second POI data to the second POI data. 2 is transmitted to the information processing terminal 4 owned by the user 34 .

The information processing terminal 4 of this embodiment has three functions for displaying the second POI data on the display device 43 .

The first is a function of displaying a map 65 showing a predetermined number of POIs on the display device 43, as shown in FIGS. FIG. 3 shows an example of a map 65 representing areas with a relatively large number of POIs. FIG. 4, on the other hand, shows an example of a map 65 representing an area with relatively few POIs. The map 65 shows POIs with pin icons 64 . In this embodiment, the number of POIs indicated by map 65 of FIG. 3 and the number of POIs indicated by map 65 of FIG. 4 are equal. This can be realized by adjusting the scale of the map 65 by the scale determining unit 47 . The scale determining unit 47 adjusts the scale of the map 65 so that the number of POIs to be displayed becomes a predetermined number regardless of the number of POIs around the reference position. Specifically, as shown in FIG. 4, the scale determining unit 47 makes the scale of the map 65 representing areas with relatively few POIs larger than the scale of the map 65 representing areas with relatively many POIs. By increasing the scale of the map 65, the area represented by the map 65 displayed on the display device 43 becomes wider. This allows more POIs to be shown on the map 65 than if the map 65 were at a smaller scale. If too few POIs are shown on the map 65, it will be difficult for the second user 34 to find the POIs he wishes to visit. On the other hand, if too many POIs are shown on the map 65 , the visibility of the map 65 is reduced by the pin icons 64 . Therefore, when an area having a relatively large number of POIs is represented on the map 65, the display control unit 48 is configured to select the POIs shown on the map 65 by a predetermined method. Such an information processing terminal 4 can improve user's viewability by automatically changing the scale of the map 65 showing the surrounding tourist spots by the scale determining unit 47 and selecting the POIs to be presented. can. The process of displaying the map 65 on the display device 43 is hereinafter referred to as "map display process". The map display process is a process of causing the display device 43 to display the map 65, which is an image showing the map 65 within a specific geographical range.

The second function is to display the second POI data as a list on the display device 43 based on the display order information, as shown in FIG. The display order of the second POI data is determined based on the first attribute and the second attribute. For example, the display order of the second POI data that has been viewed relatively frequently by the first user 31 who has the same first attribute as the second attribute is the second POI data which has the same first attribute as the second attribute. It is higher than the display order of the second POI data that has been browsed by one user 31 relatively few times. For example, the display order of the second POI data evaluated relatively highly by the first user 31 who set the same first attribute as the second attribute is the display order of the first user 31 who set the same first attribute as the second attribute. 31 ranked lower than the second POI data. For example, the display order of the second POI data, which has been recorded relatively frequently by the first user 31 who has the same first attribute as the second attribute, is the second POI data which has the same first attribute as the second attribute. It is higher than the display order of the second POI data, which is recorded by one user 31 relatively few times. For example, the display order of the second POI data browsed or recorded by the first user 31 who set the same first attribute as the second attribute is the first user 31 who set the first attribute different from the second attribute. is higher than the display order of the second POI data browsed or stored by .

In this way, the information processing terminal 4 weights the POIs based on the first attribute and the second attribute, for example, rearranges and presents information on tourist spots to the second user 34 , thereby allowing the second user 34 to , and encourage the second user 34 to go out. Hereinafter, the process of displaying the second POI data list in the display order based on the first attribute and the second attribute will be referred to as "list display process". That is, the list display process is a process of displaying a list of peripheral information existing within a specific geographical range on the display device 43 .

The third function is to display the second POI data on the display device 43 in display order based on the trend, as shown in FIG. The third function is similar to the second function, except that the display order is determined based on trends instead of the second attribute.

In this embodiment, these three functions are switched to each other by three switching buttons 78,79,80. The switch button 78 corresponds to the first function. The switch button 79 corresponds to the second function. The switching button 80 corresponds to the third function. In other embodiments of the present invention, the information processing terminal 4 may be configured to have at least one of these three functions.

The information processing terminal 4 can share the second POI data with the second companion 35 . The information processing terminal 4 can share the second POI data selected by the second user 34 with the second companion 35 . The information processing terminal 4 transmits second POI data to the information processing terminal 33 shown in FIG. The information processing terminal 33 is a terminal device owned by the second companion 35 . The information processing terminal 4 can transmit the second POI data to the information processing terminal 33 when the POI sharing screen 90 shown in FIG. 8 is operated by the second user 34, for example.

<<Details of the configuration of the information processing terminal 4>>
The input device 41 shown in FIG. 2 is, for example, a touch panel integrated with the display device 43, a voice input device capable of inputting text data by voice, or a physical key. In this embodiment, the input device 41 is a touch panel. The input device 41 is operated by the first user 31 or the second user 34 .

The terminal communication device 42 performs data communication with an external device. The terminal communication device 42 communicates with the database server 5 . In this embodiment, the terminal communication device 42 communicates with the information processing terminal 33 . The terminal communication device 42 transmits the reference data to the database server 5 . Reference data indicates a reference position. In this embodiment, the reference data includes latitude information and longitude information. In this embodiment, the terminal communication device 42 receives second POI data from the database server 5 .

The terminal communication device 42 transmits the second attribute data to the database server 5 when the list display process is executed. The second attribute data is input to the input device 41 by the operation of the second user 34 .

The display device 43 is configured to display various types of information. The second attribute data is input by the second user 34 when, for example, an attribute input screen (not shown) is displayed on the display device 43 . The attribute input screen is configured so that any one of, for example, friends, family, lover, or one person can be selected as the second attribute. The attribute input screen may be configured so that the second attribute can be selected from the POI image. Specifically, the attribute input screen is configured so that you can select one of the following images: “Friends and excitement”, “Family excitement”, “Couple excitement”, “Couple leisure”, or “Mattari alone”. There may be. The attribute input screen may be configured to allow the second user 34 to set the scene in which the application is used. The usage scene is, for example, a day trip or a day trip to a hot spring. The first attribute data, for example, the second attribute data, is input to the information processing terminal 4 in the same manner.

In this embodiment, the display device 43 can visualize the second POI data in different ways for each of the above three functions.

A map 65 related to the map display process includes pin icons 64 and reference marks 63a, as shown in FIGS. A pin icon 64 indicates a POI. A pin icon 64 represents the type of POI. The type of POI is represented by a figure with a different design for each type of POI. The types of POIs are, for example, restaurants, tourist facilities, shops, or public facilities. A reference mark 63a indicates a reference position. The reference position is also the center point 63b of the display range 65a in which the map 65 is displayed on the display device 43 when the map 65 is not scrolled.

In this embodiment, the display device 43 displays a list of second POI data in the simple information area 62 when a POI within the display range 65a of the map 65 displayed along the center point 63b is detected. . A simple information area 62 is the area below the map 65 . The display device 43 displays the map 65 and the simple information area 62 on one screen 61 . A simple information area 62 shows simple information about the POI. The simple information area 62 displays photographic image data 68 and text data. Photographic image data 68 represents, for example, the appearance of a building at the POI. The photographic image data 68 represents, for example, food served at a store located at the POI. In this embodiment, the photographic image data 68 corresponds to the image data included in the first POI data. The text data includes text data 69 indicating the name of the POI. In this embodiment, the text data further includes text data indicating the impression of the POI. Text data indicating the impression of the POI is displayed, for example, in a range 70 surrounded by a two-dot chain line. The text data corresponds to text data included in the first POI data.

In this embodiment, the simple information area 62 displays a type icon 64a. The type icon 64 a represents the same type of POI as the pin icon 64 . The type icon 64a corresponds to the POI indicated by the map 65. FIG. The type icon 64a is graphically associated with the POI indicated by the pin icon 64 . In this embodiment, the type icon 64a is arranged next to the text data 69 indicating the POI name.

In this embodiment, the display device 43 displays second POI data indicating POIs plotted on the map 65 in the simple information area 62 . The display device 43 displays the second POI data in the simple information area 62 in order of proximity from the center point 63b. Therefore, the display device 43 displays the second POI data indicating POIs relatively close to the reference position higher in the list than the second POI data indicating POIs relatively far from the reference position. In this embodiment, the simple information area 62 displays the second POI data in three columns and three rows. The second POI data at the top of the list is displayed at a position closer to the map 65 than the second POI data at the bottom of the list.

The order in which the display device 43 displays the second POI data in the simple information area 62 is not limited to the order of proximity to the center point 63b. The order may be determined based on the time required for the second user 34 to go to the POI from the center point 63b depending on the means of transportation. Examples of means of transportation include walking and automobiles. In this case, the order is, for example, the shortest required time according to the means of transportation. The order may also be determined based on attributes of the POIs. The attributes of POIs are features, genres, and the like of POIs. Further, the display device 43 may be configured to display the second POI data corresponding to the POI requested for PR (Public Relations) at the top of the list. A PR request is a request for advertising from a company, store, or the like located at the POI. In this case, the order of the remaining second POI data that has not received a PR request is, for example, the order of proximity from the center point 63b, the order based on the required time according to the means of transportation, and the order based on the POI attributes.

The display device 43 can focus and display the second POI data corresponding to the pin icon 64 selected by the second user 34 among the second POI data displayed in the simple information area 62 . In this embodiment, the display device 43 can highlight the second POI data corresponding to the pin icon 64 pressed by the second user 34 . As a result, the POIs shown on the map 65 and the POIs shown in the simple information area 62 are associated with each other.

The terminal control device 44 controls various information processing operations. The terminal control device 44 is electrically connected to the input device 41 , the terminal communication device 42 , the display device 43 and the terminal storage device 49 . The terminal control device 44 is configured to be able to control the input device 41 , the terminal communication device 42 and the display device 43 based on a program stored in the terminal storage device 49 . The terminal control device 44 is composed of, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit).

The terminal communication control unit 45 controls the terminal communication device 42 to communicate with the database server 5 . When the reference position is determined by the reference determination unit 46 , the terminal communication control unit 45 transmits the reference data to the database server 5 . The terminal communication control unit 45 can also control the terminal communication device 42 to communicate with the information processing terminal 33 .

A reference determination unit 46 determines a reference position. The reference position serves as a reference for determining the reference range 66 and the search range. The reference position is represented by longitude and latitude, for example. The reference position may be represented by longitude, latitude and altitude. Characters indicating the reference position are displayed in the address box 67 . The address box 67 displays characters indicating the current location of the second user 34, for example. In this embodiment, address box 67 is displayed between map 65 and simple information area 62 .

The reference determination unit 46 determines the reference position based on the current location of the second user 34, for example. In this case, the reference determination unit 46 identifies the current location of the second user 34 using a current location detection device (not shown). The reference determination unit 46 determines the specified current location as the reference position. In this embodiment, the current location detection device is GPS. The reference determination unit 46 may determine the reference position based on the position of the second user 34 when the application was used last time.

The reference determination unit 46 may determine the position indicated by the second user 34 as the reference position. For example, the display device 43 can scroll the displayed map 65 by the operation of the second user 34 . In this case, the reference determining unit 46 determines the reference position by moving the center point 63b as the map 65 is scrolled. That is, the reference determining unit 46 determines the center point 63b of the display range 65a of the map 65 after scrolling as the reference position.

The reference determination unit 46 may determine the reference position by keyword search by the second user 34 . In this case, the reference determination unit 46 determines the reference position based on, for example, the text data indicating the address of the specific location input via the input device 41 or part thereof, the station name, the facility name, or the place name. For example, the address box 67 shown in FIGS. 3 and 4 is used for inputting text data. When determining the point specified by the second user 34 as the reference position, the reference determining unit 46 can use coordinate data based on a specific location.

In this manner, the reference determination unit 46 sets the reference position according to the second user 34 . The reference range 66 extends to a predetermined size with reference to the reference position. Reference range 66 is used to determine the scale of map 65 . In this embodiment, the reference range 66 is circular with the reference position as the center. The reference range 66 preferably has a radius of 300 m or more and 1200 m or less from the reference position. The reference range 66 preferably has a radius of 500 m or more and 900 m or less from the reference position. In this embodiment, the reference range 66 is a range with a radius of 700 m from the reference position. Note that the reference range 66 indicated by two-dot chain lines in FIGS. 3 and 4 is an image, and the reference range 66 is not shown on the map 65 . Note that the reference range 66 is not limited to a circle centered on the reference position. The reference range 66 may be a polygon such as a triangle, a square, or a trapezoid. If the reference range 66 is set with reference to the reference position, it does not have to be centered on the reference position.

The search range expands to a predetermined size with reference to the reference position. The search range is used to acquire the second POI data. The search unit 54 acquires the second POI data from the database 57 based on the search range. Specifically, the search unit 54 acquires second POI data indicating two or more POIs within the search range from the database 57 . The search range is a range larger than the reference range 66 . If the number of POIs included in the reference range 66 is less than a predetermined number, the search range may be a range that includes at least the POIs that are outside the reference range 66 and are closest to the reference position. In this case, the search range is, for example, a range that includes a predetermined number of POIs in total within the reference range 66 and outside the reference range 66 . Alternatively, in this case, the search range is, for example, a range that includes POIs outside the reference range 66 and closest to the reference position. The search range may be changed as appropriate according to the number and positions of POIs outside the reference range 66 .

In the map display process, the scale determination unit 47 determines the scale of the map 65 based on the number of POIs included in the reference range 66 and the number of POIs to be displayed. The scale determination unit 47 acquires second POI data indicating POIs within the reference range 66 in order to determine the scale. Also, the scale determination unit 47 determines the number of POIs to be displayed. The number of POIs to be displayed is set to a predetermined number that does not prevent the second user 34 from viewing the map 65 . The predetermined number is preferably 4 or more and 16 or less. The predetermined number may be determined based on the ratio of the area of the map 65 and the simple information area 62 to the entire screen 61 . The area ratio of the simple information area 62 to the screen 61 is, for example, 30% or more and 60% or less. The predetermined number may be determined based on the size of one piece of second POI data displayed in the simple information area 62 . The predetermined number may be determined based on the area ratio of the simple information area 62 to the screen 61 and the size of one piece of second POI data displayed in the simple information area 62 . In this case, the predetermined number increases as the area ratio of the simple information area 62 increases or as the size of the second POI data displayed in the simple information area 62 decreases. The predetermined number is nine in this embodiment. In this embodiment, the number of POIs indicated by the map 65 is constant regardless of the area. Note that the information output system 3 of the present embodiment is not limited to this configuration, and may be configured to adjust the predetermined number each time the map display process is performed.

The scale determining unit 47 detects the number of POIs within the reference range 66 based on the second POI data. The scale determination unit 47 determines the scale of the map 65 representing the area where the number of POIs in the reference range 66 exceeds the predetermined number or exceeds the predetermined number, to a predetermined scale. The predetermined scale is such that a range slightly larger than the reference range 66 is the display range 65 a of the map 65 . In this embodiment, the predetermined reduced-scale map 65 can show relatively narrow roads as well as relatively wide roads such as highways and national highways.

The scale determination unit 47 makes the scale of the map 65 representing the area where the number of POIs included in the reference range 66 is less than the predetermined number larger than the predetermined scale. Specifically, when the number of POIs included in the reference range 66 is less than a predetermined number, the scale determination unit 47 determines the scale so that the POIs outside the reference range 66 and closest to the reference position can be shown. . That is, when the number of POIs included in the reference range 66 is less than a predetermined number, the map 65 shows at least POIs outside the reference range 66 and closest to the reference position as POIs. Note that the POI used as a reference for scale determination is not limited to the POI closest to the reference position, and may be any POI that is outside the reference range 66 and has a predetermined order of proximity from the reference position. The predetermined rank is a value smaller than a predetermined number. Such a map 65 shows POIs of a predetermined rank outside the reference range 66 at the ends of the display range 65a.

For example, when there are less than eight POIs within a radius of 700 m from the center point 63b, the scale determining unit 47 determines the scale of the map 65 so that nine or more POIs are included in the display range 65a. . On the other hand, for example, when there are nine or more POIs within a radius of 700 m from the center point 63b, the scale determination unit 47 determines a predetermined scale corresponding to a short side of the map 65 in height or width corresponding to a predetermined distance. The scale of the map 65 is determined so that The predesignated distance is, for example, 1400m. As a result, 9 pins are set up on the map 65 at the locations corresponding to the POIs, and the second POI data corresponding to the 9 POIs are displayed in the simple information area 62 as a list. In the case of an approximate value, the previously specified distance may be 1400 m or more. In this case, there may be more than 9 pins at each location corresponding to a POI on map 65 . In this manner, the scale determination unit 47 determines the scale of the map 65 based on the number of POIs existing within a specific range from the specified point. If there are less than a predetermined number of POIs within the reference range 66, the scale determination unit 47 displays the map 65 at a scale that allows the predetermined number of POIs to be displayed on the map 65. FIG. If there are more than a predetermined number of POIs within the reference range 66, the scale determining unit 47 sets the scale to correspond to the distance specified by the short side of the map 65 in height or width.

The display control unit 48 determines POIs to be plotted on the map 65 . The display control unit 48 can select POIs shown on the map 65 when there are more than a predetermined number of POIs within the reference range 66 . In the present embodiment, the display control unit 48 displays on the display device 43 a map 65 in which a predetermined number of pin icons 64 are plotted in order of proximity to the specified point at the scale determined by the scale determination unit 47 .

In this embodiment, the display control unit 48 displays the simple information area 62 in accordance with the scrolling of the simple information area 62 by the second user 34 when there are more than a predetermined number of POIs at the time of the scale determination. The configuration shows only the pin icon 64 corresponding to the displayed second POI data. That is, only the pin icons 64 corresponding to the list displayed in the simple information area 62 are displayed, and the pin icons 64 included in the map 65 are changed to pin icons 64 indicating other POIs as the list is scrolled. Configured. If the list is scrolled, the map 65 and address box 67 are static, not scrolled.

For example, when there are nine or more POIs within the reference range 66, the display control unit 48 is configured to scroll the list and present up to 39 POIs. Further, for example, when second POI data corresponding to nine POIs are displayed in the simple information area 62, when the simple information area 62 is scrolled to display the second POI data after the tenth item, A pin icon 64 corresponding to the tenth and subsequent POI data appears on the map 65 . In this manner, the display control unit 48 is configured to display the updated list of POIs on the display device 43 as the map 65 is scrolled or enlarged/reduced. When the reference range 66 includes more than a predetermined number of POIs, the display control unit 48 obtains the ranks of the POIs included in the reference range 66 based on the distances between the center point 63b and the POIs. POIs closer to the center point 63b are ranked higher. The display control unit 48 displays a predetermined number of POIs on the map 65 in descending order from the reference position or center point 63b.

When only the scale of the map 65 displayed on the display device 43 is changed by the second user 34, the terminal control device 44 displays the pin icon 64 corresponding to the acquired second POI data and the POI list. to maintain On the other hand, when the center point 63b is changed by the second user 34, the terminal control device 44 acquires the second POI data again. When the center point 63b is changed after the scale of the map 65 is changed, the terminal control device 44 acquires the second POI data and displays the list based on the above logic while maintaining the scale of the map 65. I do.

If it takes time to read or display the second POI data, the display control unit 48 may cause the display device 43 to display characters indicating that the process is in a wait state.

The display control unit 48 may be configured to display a reference button (not shown). The reference button is a button for returning the center point 63b of the display range 65a to the reference position. The display control unit 48 displays the reference button on the screen 61 together with the map 65 . For example, when the reference button is pressed while the map 65 is scrolled, the display control unit 48 can display the map 65 showing the current location of the second user 34 as the center point 63b on the display device 43 as a shortcut. can. Note that the display control unit 48 may gray out the reference button and display it on the screen 61 when the second user 34 does not allow the application to use the GPS data acquired by GPS.

When the terminal control device 44 determines that the next action will not continue even if the map 65 is pinched or scrolled, it starts reloading the second POI data. The time at which reading is resumed is, for example, 0.5 seconds.

In this embodiment, the display control unit 48 displays the map 65 on the display device 43 by default when the application is started. The center point 63b of the display range 65a during screen display corresponds to, for example, the current location of the second user 34 at the start of screen display. If the use of GPS is not permitted when the application is started for the first time, the reference determining unit 46 may set a predetermined point such as Tokyo Station as the reference position. If the use of GPS is not permitted, the reference determination unit 46 may set the center point 63b of the map 65 when the application was used last time as the reference position. The display control unit 48 may be configured not to use the map 65 as a default when the application is started for the first time.

In this embodiment, the list screen 71 shown in FIG. 5 includes a header area 72 , a list area 73 and a footer area 74 . Header area 72 includes reference position box 75 and attribute box 76 . The footer area 74 includes three switching buttons 78,79,80. The list area 73 is scrolled by the operation of the second user 34 . The direction of scrolling is, for example, the vertical direction. The header area 72 and footer area 74 are fixed without being scrolled.

When the list display process is executed, the second POI data includes display order information. The display order information indicates the display order of the second POI data respectively indicating two or more POIs within the reference range 66 . The display order is determined based on at least the first attribute and the second attribute. Upon receiving the second POI data, the display control unit 48 outputs the second POI data as a list in descending order of score. List area 73 displays photographic image data 68 and text data. As for the text data, text data 69 indicating the name of the POI is displayed in association with the photograph image data 68 . In this embodiment, the text data displays characters indicating the impression of the POI in an area 70 surrounded by a two-dot chain line. In this embodiment, the text data indicates the break level of each POI. The degree of breaking is indicated, for example, by a star-shaped figure 81 . In this embodiment, the text data is shown in a range 77 in which characters indicating the location of the POI are indicated by two-dot chain lines. In this embodiment, the POI list arranges the second POI data vertically. In this embodiment, a plurality of photographic image data 68 are displayed side by side for each POI.

When the list screen 71 starts to be displayed, the terminal control device 44 reads second POI data indicating, for example, five POIs. Each time the list screen 71 is scrolled by the second user 34 , the display control unit 48 sequentially reads the second POI data indicating the next five POIs in order of display order and causes the display device 43 to display them. In this embodiment, the list at the start of display is the list when starting from the current location of the second user 34 . That is, it is a list in which the second POI data are arranged in order of proximity from the current location of the second user 34 . The list at the start of display may be a list starting from the last center point 63b of the map 65 when the application was last used when the second user 34 does not permit the use of GPS. The list at the start of display may be a list when departing from a specific point. When the starting point is changed, the name of the city, town, village, ward, or the like after the change is displayed in the reference position box 75 . For example, the characters in the reference position box 75 change from "start from current location" to "start from Chiyoda Ward". In this case, the usage scene may be inherited from the previous settings.

The detailed screen 83 shown in FIG. 7 shows detailed information 83 a of the POI selected by the second user 34 . The detailed screen 83 transitions from the screen 61 shown in FIGS. 3 and 4, the list screen 71 shown in FIG. 5, or the list screen 71 shown in FIG. The screen 61 , the list screen 71 , or the list screen 71 transitions to the detailed screen 83 when the second POI data of each list is pressed by the second user 34 . The detail screen 83 may be opened with the screen 61 , the list screen 71 , or the text data within the range 70 pressed by the second user 34 on the screen 61 , the list screen 71 , or the text data in the range 70 being displayed in the center.

On the detailed screen 83 , the display device 43 displays the map 65 , the photo image data 68 , the text data, and the share icon 84 . The detail screen 83 may further include a peripheral information column 86 . The surrounding information column 86 displays second POI data indicating other POIs surrounding the POI selected by the second user 34 . That is, in the present embodiment, the detailed information 83a includes the map 65 indicating the POI selected by the second user 34, the photo image data 68, the text data, the image data of the share icon 84, and the peripheral information column 86. including information. In addition, the detailed information 83a is not limited to the above as long as it includes information to the extent that the POI selected by the second user 34 can be visited.

The display device 43 displays a POI sharing screen 90 shown in FIG. 8 when the share icon 84 is pressed. The POI share screen 90 displays a share execution button 89 . In this embodiment, the POI sharing screen 90 displays weather forecast data 87 . The weather forecast data 87 indicates, for example, the weather forecast for the next week. In this embodiment, the POI sharing screen 90 displays POI photo image data 68 and text data. The terminal communication device 42 transmits the second POI data displayed on the POI sharing screen 90 to the information processing terminal 33 of the second companion 35 when the share execution button 89 is pressed.

The terminal storage device 49 shown in FIG. 2 has a volatile storage device in which information disappears when power is turned off, and a non-volatile storage device in which information does not disappear even when power is turned off. Volatile storage temporarily stores information processed by terminal controller 44 . The volatile storage device stores, for example, map data showing the map 65 and point information to be added to the map data. Volatile storage devices include, for example, RAM (Random Access Memory). A non-volatile memory device is a storage capable of storing various information processing programs and various types of information. Non-volatile storage devices include, for example, ROM (Read Only Memory). For ROM, for example, flash memory or HDD (Hard Disk Drive) is used.

The information processing terminal 4 as described above corresponds to a computer. Each component of the above-described embodiment is implemented by the CPU executing a software program stored in the terminal storage device 49, for example. The program may be executed by being downloaded from a server (not shown).

<<Configuration of database server 5>>
In this embodiment, the server communication device 51 shown in FIG. 2 performs data communication with an external device. In this embodiment, the server communication device 51 communicates with the SNS server 23 and receives POI data from the SNS server 23 . The server communication device 51 communicates with the information processing terminal 4 . The server communication device 51 receives reference data from the information processing terminal 4 . Server communication device 51 transmits the second POI data to information processing terminal 4 . When the list display process is executed, the server communication device 51 transmits second POI data including display order information to the information processing terminal 4 . The server communication device 51 is controlled by a server communication control section 53 .

The server control device 52 is electrically connected to the server communication device 51, the server storage device 56, and the database 57, respectively. The server control device 52 drives, for example, various programs stored in the server storage device 56 to operate. The server control device 52 is composed of, for example, a CPU or an MPU.

The search unit 54 searches the database 57 for POI data. Specifically, the search unit 54 acquires from the database 57 the second POI data respectively indicating the POIs included in the search range. That is, the search unit 54 searches for POIs within a certain distance from the specified point from among the plurality of POIs. The search range is, for example, a range within a radius of 100 km or more and 200 km or less from the reference position. More preferably, the search range is a radius of 130 km or more and 170 km or less from the reference position. If the number of POIs within the reference range 66 is less than a predetermined number, the search range may be a range that includes a predetermined number of POIs in descending order from the reference position. In the map display process, if the number of POIs included in the reference range 66 is less than a predetermined number, the search range may be a range that includes POIs outside the reference range 66 and closest to the reference position.

The order determination unit 55 determines the display order based on the POI data retrieved by the retrieval unit 54 . The order determination unit 55 determines the display order based on at least the first attribute and the second attribute. In this embodiment, the ranking determining unit 55 scores POIs existing in a specific area based on the following three factors.

(a) topicality of each POI (b) distance from the center point 63b to each POI (c) desirability of each POI

(a) The topicality of each POI is scored according to whether it is a POI worth visiting in the near future. In this embodiment, the ranking determination unit 55 uses the SNS server 23 for this scoring. In this embodiment, the ranking determining unit 55 determines the second POI data based on the newness of the first POI data corresponding to the second POI data and the evaluation of the first POI data corresponding to the second POI data. of POI data are scored.

Specifically, the ranking determining unit 55, for example, sets the score so that the second POI data corresponding to the first POI data posted on the SNS on the day before the list display process is executed has the maximum value. attach. The ranking determining unit 55 assigns a score so that the older the POI data, the lower the score gradually from the maximum value. The score attached to the second POI data is updated daily. For scoring, the ranking determination unit 55 acquires information indicating the date when the first POI data corresponding to the second POI data was transmitted from the information processing terminal 22 to the SNS server 23, that is, the date of posting. Alternatively, the ranking determination unit 55 acquires information indicating the number of days that have passed since the posting date. Alternatively, the ranking determination unit 55 acquires information indicating how short the number of days has passed since the posting date. In this embodiment, the ranking determination unit 55 acquires information indicating how short the number of days is from the date of posting to the SNS or service to the date of acquisition. The acquisition date is the date on which the information was acquired by the ranking determination unit 55 .

Also, the ranking determination unit 55 scores based on at least one of the number of retweets and the number of “likes” per day. Specifically, for example, the ranking determining unit 55 multiplies the number of retweets and the number of “likes” for each day by a period to score them. That is, the ranking determination unit 55 scores the second POI data based on the extent to which the first POI data has spread to other SNS users 21 . The ranking determination unit 55 assigns a higher score to the second POI data corresponding to the first POI data spread to more SNS users 21 . For scoring, the ranking determining unit 55 acquires information indicating the number of users who retweeted the first POI data corresponding to the second POI data. The ranking determining unit 55 also acquires information indicating the number of "likes" given to the first POI data corresponding to the second POI data. Accordingly, the ranking determining unit 55 can acquire information indicating the number of SNS users 21 who gave a favorable evaluation to the first POI data corresponding to the second POI data. In this embodiment, the database server 5 acquires such information in advance for all POIs indicated by the POI data acquired from the SNS server 23 . As described above, the ranking determination unit 55 of the present embodiment multiplies the score regarding the newness of the POI data by the score regarding the extent to which the POI data has been spread to other SNS users 21, thereby scoring each POI. conduct.

For example, the search unit 54 acquires second POI data indicating POIs existing within a radius of 150 km from the reference position from the database 57, and out of the 200,000 POIs nationwide, five spots A to E are searched. Assume that you have obtained In this case, the ranking determining unit 55 scores the topicality of spots A to E as shown in Table 1, for example.

As shown in Table 1, Spot E scored higher than Spot A, Spot B, Spot C and Spot D scores. Spot E is a POI with the latest posting date of the corresponding first POI data. In this way, the score given by the ranking determination unit 55 is higher for POIs corresponding to POI data posted on a relatively new date than POIs corresponding to POI data posted on a relatively old date. The score given by the ranking determination unit 55 is higher for POI corresponding to POI data with a relatively large number of retweets than POI corresponding to POI data with a relatively small number of retweets. The ranking determination unit 55 multiplies the score based on the posting date by the score based on the number of retweets to score the topicality of the POI.

(b) The distance from the center point 63b to each POI is scored according to whether it is really within a reachable distance, ie, the ease of access. As for the score, based on the usage scene of the second user 34, the score of the POI at the appropriate distance for each usage scene becomes the maximum value. The usage scene is selected together with the second attribute on the attribute input screen described above, for example. For example, the ranking determination unit 55 scores the maximum value of the distance from the current location of the second user 34 that is easy to go for a day drive. A distance suitable for a day drive is, for example, 30 km or more and 50 km or less.

(b) To score the distance to each POI, the ranking unit 55 scores the POIs based on the distance from the center point 63b to each POI. The ranking determination unit 55 assigns a higher score to a POI having a shorter distance. For scoring, the ranking determination unit 55 calculates the distance from the coordinates designated as the starting point to the coordinates of each POI. In this embodiment, coordinate information indicating coordinates includes latitude information and longitude information. The ranking determination unit 55 calculates the distance based on the map data stored in the server storage device 56, for example. The ranking determination unit 55 may score each POI so that the most appropriate distance becomes the maximum value according to what kind of spot the second user 34 is looking for. The POIs that the second user 34 is looking for include, for example, day trip resorts and overnight trips. If the usage scene selected by the second user 34 is a day trip, spots A to E are given scores as shown in Table 2, for example. A suitable distance for day trips is, for example, 20 km or more and 40 km or less.

As shown in Table 2, spot C and spot D scores higher than spot A, spot B and spot E scores. Spot A and spot D are POIs at distances that match the usage scene. Spot A, spot B, and spot E are POIs at distances that do not match the usage scene.

(c) The desirability of each POI is scored according to whether the POI is of interest to persons of the same companion attribute. Each POI's preference corresponds to the POI's context. A person with the same companion attribute is the first user 31 for whom the same first attribute as the second attribute is set. In the present embodiment, the ranking determination unit 55 scores the number of times the detailed information 83a has been viewed and the number of bookmarks by the first user 31 for each attribute of the second POI data. Scores are updated daily. The order determination unit 55 multiplies and weights these parameters to determine the display order of the second POI data. Note that the degree of importance between parameters may be adjusted as appropriate. Also, the ranking determining unit 55 may be configured to recommend POIs to the second user 34 based on the preference of each POI.

For example, the ranking determination unit 55 assigns the second POI data having a relatively large number of viewing times of the detailed information 83a by the first user 31 who has the same first attribute as the second attribute to the second POI data having the same first attribute as the second attribute. is given a higher score than the second POI data whose detailed information 83a is browsed by the first user 31 with a relatively small number of times. For example, the order determining unit 55 sets the same first attribute as the second attribute to the second POI data that has been bookmarked relatively frequently by the first user 31 to which the same first attribute as the second attribute is set. A higher score is given to the second POI data that has been bookmarked by the first user 31 that has been bookmarked a relatively small number of times. In this way, the ranking determining unit 55 scores each POI based on whether the first user 31 who has the same first attribute as the second attribute browses or bookmarks many or few POIs. The ranking determination unit 55 multiplies the coefficients according to the type of action, such as browsing only, bookmarking only, or both actions, when scoring. When the second attribute set by the second user 34 is "family", the order determining unit 55 determines the second attribute of the second companion 35 for each second companion 35 from spot A to spot E as shown in Table 3, for example. See the score for

As shown in Table 3, Spot A scored higher than Spots B-E scores. Spot A is a POI browsed or bookmarked by the first user 31 whose first attribute is "family". Spots B to E are POIs viewed or bookmarked by the first user 31 whose first attribute is other than "family".

Note that AI (artificial intelligence) learning may be used to score the desirability of each POI. Note that the ranking determination unit 55 may be configured to score each POI based on the POI attribute preset by the service provider of the application, for example, without using the first attribute. That is, the ranking determination unit 55 scores each POI based on the POI attribute and the second attribute. For example, the ranking determination unit 55 assigns high scores to POIs whose attribute is a park in the order of family, lover, and one second user 34 as the second attribute. In this case, the ranking determining unit 55 makes the POI score higher when the second attribute is family than the POI score when the second attribute is lover. The ranking determining unit 55 makes the POI score higher when the second attribute is lover than the POI score when the second attribute is single.

In this embodiment, the ranking determination unit 55 determines the overall ranking of two or more POIs based on the scores (a), (b), and (c) above. In this embodiment, the display ranking information indicates overall ranking.

As shown in Table 4, the display order is spot D, spot E, spot C, spot A, and spot B.

The score calculated in this way may be abstracted and displayed on the display device 43 together with the second POI data.

The server storage device 56 has a volatile storage device in which information disappears when the power is turned off, and a non-volatile storage device in which the information does not disappear even when the power is turned off. Volatile storage temporarily stores information processed by server controller 52 . An example of a volatile memory device is, for example, RAM. The server storage device 56 stores map data.

The database 57 stores POI data in association with the first attribute. The database 57 classifies and stores the POI data for each category. In the present embodiment, the database 57 indicates a plurality of POIs converted by adding spot names and position information based on information transmitted via SNS and the first POI data posted by the SNS user 21. Registered POI data.

In this embodiment, the database server 5 stores first attribute data input by the first user 31 via the input device 41 . Specifically, the database server 5, for all the POIs indicated by the second POI data stored in the database 57, allows the detailed information 83a to be browsed and the second POI data to be bookmarked by the first user 31. It is configured so that the first attribute can be recorded.

The database server 5 that determines the display order by the above algorithm corresponds to a computer. Each component of the above-described embodiment is implemented by the CPU executing a software program stored in the server storage device 56, for example.

≪Map display processing≫
The map display process shown in FIG. 9 is started, for example, when an application is activated. The map display process is started, for example, when the switch button 78 shown in FIGS. 5 and 6 is pressed by the second user 34 .

In step S1, the reference determination unit 46 determines a reference position.

In step S2, the scale determination unit 47 requests the database server 5 for the second POI data. In this case, the terminal communication device 42 transmits the reference data to the database server 5 . The reference data indicates the reference position determined in step S1.

In step S<b>3 , the search unit 54 acquires POI data indicating POIs within the search range from the database 57 .

In step S<b>4 , the server communication control section 53 transmits the second POI data to the information processing terminal 4 . The second POI data includes the POI data acquired by the search unit 54 in step S3.

At step S5, the scale determining unit 47 detects the number of POIs present in the reference range 66 based on the second POI data transmitted at step S4.

In step S<b>6 , the scale determination unit 47 determines the scale of the map 65 . The scale determining unit 47 determines the scale of the map 65 based on the number of POIs detected in step S5. The scale determination unit 47 determines the scale of the map 65 to be a predetermined scale when there are a predetermined number of POIs or more than a predetermined number of POIs within the reference range 66 . If there are less than a predetermined number of POIs within the reference range 66, the scale determination unit 47 determines the scale of the map 65 to a scale that can show the POIs outside the reference range 66 and closest to the reference position.

In step S7, the display control unit 48 displays the map 65 on the display device 43 at the scale determined in step S6. The display control unit 48 selects the POIs shown on the map 65 when there are more than a predetermined number of POIs within the reference range 66 . As a result, a map 65 showing a predetermined number of POIs is displayed on the display device 43 . The display control unit 48 also displays the second POI data in the simple information area 62 . With this, the information output system 3 terminates the map display processing.

≪List display processing≫
The list display process shown in FIG. 10 is started when the second user 34 taps the switch button 79 shown in FIGS. 3, 4 and 6, for example.

In step S11, the reference determination unit 46 determines the reference position.

In step S12, the terminal control device 44 requests the database server 5 for the second POI data. In this case, the terminal communication device 42 transmits the reference data to the database server 5 . The reference data indicates the reference position determined in step S11. The terminal communication device 42 transmits the second attribute data to the database server 5 .

In step S<b>13 , the search unit 54 acquires second POI data indicating POIs existing in the search range from the database 57 . The search range is set based on the reference position determined in step S11.

In step S14, the ranking determination unit 55 scores the topicality of POIs based on the second POI data acquired by the search unit 54 in step S13.

In step S15, the ranking determining unit 55 scores the distance from the reference position to the POI based on the second POI data acquired by the searching unit 54 in step S13.

In step S16, the ranking determination unit 55 scores the POI desirability based on the second POI data acquired by the search unit 54 in step S13.

In step S15, the order determination unit 55 generates display order information based on the display order. The ranking determining unit 55 sums the POI topicality score determined in step S14, the distance score to the POI determined in step S15, and the POI desirability score determined in step S16. Then, the display order of the second POI data is obtained.

In step S<b>18 , the server communication control unit 53 transmits second POI data including display order information to the information processing terminal 4 .

In step S<b>19 , the display control unit 48 displays the second POI data on the display device 43 . The information output system 3 thereby ends the list display process.

As described above, the information processing terminal 4 of this embodiment includes the display device 43 and the terminal control device 44 . The display device 43 displays a map 65 . The terminal control device 44 displays a map 65 based on the second POI data. The second POI data indicates two or more POIs around the reference location. A reference position is set arbitrarily. A map 65 shows a predetermined number of POIs. The terminal control device 44 changes the scale of the map 65 displayed on the display device 43 based on the number of POIs within the reference range 66 . A reference range 66 extends from the reference position to a predetermined size. The terminal control device 44 reduces the scale of the map 65 expressing the reference range 66 containing less than the predetermined number of POIs to the scale of the map 65 expressing the reference range 66 containing the predetermined number or exceeding the predetermined number of POIs. make it larger than

Therefore, the information processing terminal 4 of the present embodiment displays the map 65 showing the predetermined number of POIs on the display device 43 without the display range 65a of the map 65 displayed on the display device 43 being changed by the second user 34. can be displayed.

As described above, when the information processing terminal 4 of the present embodiment displays the map 65 in which a plurality of POIs existing in a specific area are plotted, the scale of the map 65 and the size of the map 65 are changed according to the number of POIs existing in the vicinity. Peripheral information for outputting the map 65 can be provided by determining the number of POIs to be displayed that do not hinder browsing. If the reduced scale of the map 65 is used as the starting point, the pin icons 64 are scattered when there are many POIs existing within the range. This makes it difficult for the second user 34 to read the map 65 . In addition, if the number of displayed maps is used as the starting point, the map 65 is not optimally readable in many cases. On the other hand, the information processing terminal 4 of the present embodiment can automatically change the scale of the map 65 that displays information on nearby tourist spots, for example, and select POIs to be presented. Therefore, the map 65 can be viewed more easily by the second user 34, and the viewing behavior of the second user 34 is promoted. In addition, it is possible to attract the interest of the second user 34 and encourage the second user 34 to go out.

In this embodiment, when the reference range 66 contains less than a predetermined number of POIs, the terminal control device 44 displays the map 65 on the display device 43 at a scale that allows at least the POIs and the reference positions to be displayed on the map 65. indicate. This POI is the POI that is outside the reference range 66 and closest to the reference location. Therefore, the terminal control device 44 can reliably present the POI to the second user 34 .

Further, in the present embodiment, when the reference range 66 contains more than a predetermined number of POIs, the terminal control device 44 displays the predetermined number of POIs in the order of proximity from the reference position on the map 65, so that the second user 34 can visit. Easy-to-use POIs can be presented.

The information processing terminal 4 of this embodiment also includes a terminal communication device 42 , an input device 41 , a terminal control device 44 and a display device 43 . The terminal communication device 42 communicates with the database server 5 . The database server 5 stores the second POI data in association with the first attribute. The second POI data respectively indicate two or more POIs. The first attribute is the attribute of the first companion 32 . A first attribute is set for the first user 31 . The first user 31 is a person who browsed or recorded the second POI data on the information processing terminal 4 . The input device 41 is operated by the second user 34 . A second user 34 is someone who visits the POI. The input device 41 receives input of the second attribute data. The second attribute data indicates the second attribute. A second attribute is an attribute of the second companion 35 . The second companion 35 is someone who accompanies the second user 34 . The terminal control device 44 acquires the second POI data from the database server 5 via the terminal communication device 42 . The second POI data respectively indicate two or more POIs around the reference position. The reference position is arbitrarily set according to the second user 34 . The display device 43 displays the second POI data acquired by the terminal control device 44 . The second POI data are displayed in a display order determined based on the first attribute and the second attribute. The second attribute is indicated by second attribute data input to the input device 41 .

The information processing terminal 4 of the present embodiment displays the second POI data on the display device 43 in the display order determined based on the first attribute and the second attribute. Easy POI can be presented. Further, in the conventional technology, sorting by a single index, such as order of shortest distance, order of genre, or order of high user evaluation score, is common. Therefore, it does not match the sentiment that is determined by taking into account the context specific to outing behavior in a complex manner. The context specific to going out behavior is, for example, who are you looking for a place to go out with, or is it a place that is close enough to feel easy to visit? On the other hand, the information processing terminal 4 of the present embodiment can attract the interest of the second user 34 and encourage the second user 34 to go out.

The database server 5 of this embodiment communicates with two or more information processing terminals 4 respectively. The database server 5 includes a database 57 and a server control device 52 . The database 57 stores the second POI data in association with the first attribute. The second POI data respectively indicate two or more POIs. The first attribute is the attribute of the first companion 32 . A first attribute is set for the first user 31 . The first user 31 is a person who viewed or recorded the second POI data on the information processing terminal 4 . The server control device 52 acquires second POI data from the database 57 . The second POI data respectively indicate two or more POIs around the reference position. The reference position is arbitrarily set according to the second user 34 . A second user 34 is a visitor to the POI. The server control device 52 determines the display order based on the first attribute and the second attribute. A second attribute is an attribute of the second companion 35 . The second companion 35 is someone who accompanies the second user 34 . The display order is the order in which the acquired second POI data is displayed on the information processing terminal 4 .

Further, in this embodiment, the server control device 52 scores each POI when determining the display order. The server control device 52 associates the second POI data, which has been viewed or recorded relatively frequently by the first user 31 corresponding to the same first attribute as the second attribute, with the same first attribute as the second attribute. It scores higher than the second POI data that has been viewed or recorded by the first user 31 relatively few times. Thereby, the database server 5 can appropriately determine the display order of the second POI data.

Although the embodiments of the present invention have been described above, the device configuration, control method, and the like are not limited to the above-described embodiments.

For example, in the above embodiment, the information output system 3 may be configured so that the scale of the map 65 is determined by the database server 5 instead of the information processing terminal 4 . In this case, the second POI data includes information indicating the determined scale of the map 65 .

Further, the information output system 3 may be configured such that the display order of the second POI data is determined by the information processing terminal 4 instead of the database server 5 . In this case, the second POI data includes the first attribute data.

In the above-described embodiment, the scale determining unit 47 determines the scale of the map 65 based on the number of POIs within the reference range 66, but it is also configured to determine the scale of the map 65 based on the screen size of the display device 43. may This makes it possible to realize a mechanism for extracting a more optimal reduced scale.

In the above embodiment, the display device 43 displays the map 65 and the simple information area 62 on the screen 61, but the simple information area 62 may not be displayed.

In the above embodiment, the scale determining unit 47 enlarges the scale of the map 65 based on the number of POIs within the reference range 66, but the configuration is not limited to this as long as the POIs can be shown on the map 65 appropriately. The scale determination unit 47 may be configured to reduce the scale of the map 65 based on the number of POIs within the reference range 66 .

In this embodiment, the scale determining unit 47 adjusts the scale of the map 65 so that the number of POIs to be displayed reaches a predetermined number regardless of the number of POIs around the reference position. If possible, it is not limited to this configuration. The scale determining unit 47 may be configured to adjust the scale of the map 65 so that the number of POIs displayed exceeds a predetermined number.

Other configurations can also be modified in various ways without departing from the gist of the present invention. Also, the configurations of the above-described embodiment and modifications may be combined.
