Organization description

2 is a front perspective view of an example of a mobile terminal or a mobile terminal according to the present invention;

The disclosed portable terminal 100 has a terminal body in the form of a bar. However, the present invention is not limited thereto and may be applied to various structures such as a slide type, a folder type, a swing type, a swivel type, and two or more bodies are coupled to be relatively movable.

The body includes a casing (casing, housing, cover, etc.) that forms an exterior. In this embodiment, the case may be divided into a front case 101 and a rear case 102. Various electronic components are built in the space formed between the front case 101 and the rear case 102. At least one intermediate case may be further disposed between the front case 101 and the rear case 102.

The cases may be formed by injecting synthetic resin or may be formed of a metal material, for example, a metal material such as stainless steel (STS) or titanium (Ti).

The display unit 151, the audio output unit 152, the camera 121, the user input units 130/131 and 132, the microphone 122, and the interface 170 may be disposed in the terminal body, mainly the front case 101. have.

The display unit 151 occupies most of the main surface of the front case 101. The sound output unit 151 and the camera 121 are disposed in regions adjacent to one end of both ends of the display unit 151, and the user input unit 131 and the microphone 122 are disposed in regions adjacent to the other end. The user input unit 132 and the interface 170 may be disposed on side surfaces of the front case 101 and the rear case 102.

The user input unit 130 is manipulated to receive a command for controlling the operation of the portable terminal 100 and may include a plurality of operation units 131 and 132. The manipulation units 131 and 132 may also be collectively referred to as manipulating portions, and may be employed in any manner as long as the user operates the tactile manner with a tactile feeling.

Content input by the first or second manipulation units 131 and 132 may be variously set. For example, the first operation unit 131 receives commands such as start, end, scroll, and the like, and the second operation unit 132 controls the size of the sound output from the sound output unit 152 or the size of the sound output from the display unit 151 To the touch recognition mode of the touch screen.

Front touch

Hereinafter, the operation of the display unit 151 and the touch pad 135 will be described with reference to FIG. 3.

3 is a front view of a portable terminal for explaining an operation state of the portable terminal according to the present invention.

Various types of time information can be displayed on the display unit 151. [ These pieces of information can be displayed in the form of letters, numbers, symbols, graphics, or icons.

For the input of such information, at least one of the letters, numbers, symbols, graphics or icons may be displayed in a predetermined arrangement so as to be implemented in the form of a keypad. Such a keypad may be referred to as a so-called " virtual keypad ".

3 illustrates receiving a touch applied to the virtual keypad through the front of the terminal body.

The display unit 151 may operate in an entire area or may be operated in a divided manner. In the latter case, the plurality of areas can be configured to operate in association with each other.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively. The output window 151a and the input window 151b are areas allocated for outputting or inputting information, respectively. In the input window 151b, a virtual keypad 151c is displayed in which a number for inputting a telephone number or the like is displayed. When the virtual keypad 151c is touched, numbers and the like corresponding to the touched virtual keypad are displayed on the output window 151a. When the first manipulation unit 131 is operated, a call connection to the telephone number displayed on the output window 151a is attempted.

In addition to the input methods disclosed in the above embodiments, the display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling. By scrolling the display unit 151 or the touch pad 135, the user may move an object displayed on the display unit 151, for example, a cursor or a pointer located at an icon. Further, when the finger is moved on the display portion 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display portion 151. [ This may be useful for editing an image displayed on the display unit 151.

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad 135 are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. For example, the function may include activation or deactivation of the display unit 151 or the touch pad 135.

Proximity touch

The proximity sensor 141 described with reference to FIG. 1 will be described in more detail with reference to FIG. 4.

4 is a conceptual diagram illustrating a proximity depth of a proximity sensor.

As shown in FIG. 4, when a pointer such as a user's finger or pen approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen detects this and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to a distance between the proximity touched pointer and the touch screen (hereinafter, referred to as “proximity depth”).

In FIG. 4, for example, a cross section of a touch screen on which three proximity sensors capable of sensing three proximity depths is disposed is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d ₀ ), it is recognized as a touch touch. When the pointer is positioned below the distance d ₁ on the touch screen, the pointer is recognized as a proximity touch of a first proximity depth. When the pointer is spaced apart from the distance d ₁ or more and less than d ₂ on the touch screen, the pointer is recognized as a proximity touch of a second proximity depth. When the pointer is spaced apart from the distance d ₂ or more and less than d ₃ on the touch screen, the pointer is recognized as a proximity touch of a third proximity depth. When the pointer is positioned at a distance of more than d ₃ from the touch screen, the proximity touch is recognized as released.

Accordingly, the controller 180 may recognize the proximity touch as various input signals according to the proximity depth and the proximity position of the pointer, and perform various operation control according to the various input signals.

Meanwhile, a graphic in the form of an arrow or a finger for pointing a specific object or selecting a menu on the display unit is called a pointer or a cursor. However, the pointer is often used interchangeably to mean a finger, a stylus pen, or the like for a touch operation. Therefore, in the present specification, the graphic displayed on the display unit is referred to as a cursor to clearly distinguish the two, and a physical means for performing touch, proximity touch, and gesture such as a finger or a stylus pen is called a pointer.

Hereinafter, a method of expressing a 3D image of a mobile terminal and a display unit therefor which can be applied in embodiments of the present invention will be described.

Stereoscopic images implemented on the display unit 151 of the mobile terminal may be classified into two categories. The criterion of this division is whether different images are provided to both eyes.

First, the first stereoscopic image category will be described.

The first category is a method in which the same image is provided in both eyes (monoscopic), which can be implemented as a general display unit. More specifically, the controller 180 arranges a polyhedron generated through one or more points, lines, planes, or a combination thereof in a virtual three-dimensional space, and displays an image viewed from a specific viewpoint on the display unit 151. That's how. Therefore, the real of such a stereoscopic image may be referred to as a planar image.

The second category is a method in which different images are provided in both eyes (stereoscopic), and a method using the principle of feeling a three-dimensional feeling when a human sees an object with the naked eye. That is, two eyes of a person see different plane images when viewing the same object by the distance between them. These different planar images are delivered to the brain through the retina, and the brain fuses them to feel the depth and reality of the stereoscopic image. Therefore, although there are some differences between people, binocular disparity due to the distance between the two eyes makes a sense of three-dimensional feeling, and such binocular disparity becomes the most important element of the second category. Such binocular disparity will be described in more detail with reference to FIG. 5.

5 is a conceptual diagram for explaining the principle of binocular disparity.

In FIG. 5, it is assumed that the hexahedron 510 is visually placed in front of the eye level. In this case, the left eye planar image 520 showing only three surfaces of the top, front, and left sides of the hexahedron 510 is seen as the left eye. In addition, as the right eye, the right eye plane image 530 showing only three surfaces of the top, front, and right sides of the cube 510 is visible.

If the left eye plane image 520 is reached in the left eye and the right eye plane image 530 is reached in the right eye, even if the object is not an object in front of the eye, the person may feel as if the user actually sees the cube 510.

As a result, in order to implement the stereoscopic image of the second category in the mobile terminal, the left eye image and the right eye image, which have been viewed with the same object at a predetermined time, must be separated and reached through the display unit.

In the present specification, in order to distinguish the above two categories, for convenience, a stereoscopic image of the first category is referred to as a "2D stereoscopic image", and a stereoscopic image of the second category is referred to as a "3D stereoscopic image".

Next, an implementation method of the 3D stereoscopic image will be described.

As described above, in order to implement a 3D stereoscopic image, the right eye image and the left eye image need to be divided and reached to both eyes. Various methods for this will be described below.

1) parallax barrier method

The parallax barrier method is a method of controlling a light propagation direction by electronically driving a blocking device provided between a general display unit and both eyes so that different images may be reached in both eyes.

This will be described with reference to FIG. 6.

FIG. 6 is a conceptual diagram illustrating a method of implementing 3D stereoscopic image in a display barrier type display unit applicable to embodiments of the present invention.

The structure of the display barrier type display unit 151 for displaying a 3D stereoscopic image may have a configuration in which the switch liquid crystal 151b is combined with a general display device 151a. The optical parallax barrier 600 may be operated using the switch liquid crystal 151b to control the traveling direction of the light as shown in FIG. 6A to separate the light to reach the left and right eyes. Therefore, when an image in which a right eye image and a left eye image are combined is displayed on the display device 151a, the image corresponding to each eye is seen from the user's point of view as if it is displayed in three dimensions.

In addition, as shown in FIG. 6B, the parallax barrier 600 by the switch liquid crystal is electrically controlled so that all of the light is transmitted, thereby eliminating separation of the light by the parallax barrier so that the same image can be seen by the left and right eyes. It may be. In this case, the same function as that of the general display unit may be performed.

6 illustrates that the parallax barrier moves in parallel in one axial direction, but the present invention is not limited thereto, and a parallax barrier capable of moving in parallel in two or more axial directions according to a control signal of the controller 180 may be used. have.

2) Lens Refraction Method

The lens refraction method (lenticular) is a method using a lenticular screen provided between the display unit and both eyes, and is a method of reaching different images in both eyes by refracting the traveling direction of light through the lenses on the lenticular screen.

3) polarized glasses

It is a method of providing different images in both eyes by making the polarization directions perpendicular to each other, or providing different images in both eyes by polarizing them so that the rotation directions are different from each other in the case of circular light.

4) Active Shutter Method

As a type of glasses, the right eye image and the left eye image are alternately displayed at predetermined intervals through the display unit, and the user's glasses close the shutter in the opposite direction when the image in the corresponding direction is displayed, so that the image in the corresponding direction is displayed in the corresponding direction. How to reach the eye. That is, the left eye image only reaches the left eye while the left eye image is displayed, and the left eye image reaches the right eye only while the right eye image is displayed.

For convenience of description, it is assumed that the mobile terminal mentioned below includes at least one of the components shown in FIG. 1. In particular, the mobile terminal to which the present invention is applicable includes a display unit capable of providing a 3D stereoscopic image to a user through at least one of the aforementioned 3D stereoscopic image implementation methods.

First Example

The mobile terminal according to the first embodiment of the present invention may provide a stereoscopic user interface using a plurality of layer objects having different 3D depths in a virtual stereoscopic space.

7 illustrates display state diagrams of a stereoscopic user interface that may be implemented in a mobile terminal according to an embodiment of the present invention.

Although the following display state diagrams including FIG. 7 are shown as planar images due to the limitation of the drawing, it is assumed that the 3D stereoscopic image is provided to the user in the above-described 3D stereoscopic image implementation manner.

Referring to FIG. 7A, a total of three layer objects from layer 1 to layer 3 may be arranged in a stacked form at a predetermined interval in three-dimensional space. When the layer objects are implemented as a 3D stereoscopic image through the display unit 151, the layer 1 has a low 3D depth so that the layer 1 is located at the top and is close to the user. In addition, as layer 3 goes through layer 2, the height of placement gradually decreases, and deep 3D depth is felt to be far from the user.

These layer objects may be changed in position and / or 3D depth through a predetermined command input through the user input unit. The command input for manipulating the layer objects may include a camera 121 for photographing the location of the pointer, a proximity sensor 140 for recognizing the proximity distance of the pointer, and a touch screen capable of distinguishing the contact touch and the proximity touch ( 151), or the like. Specific command input methods using these will be described later in detail.

As an example of changing the 3D depth of the above-described layer objects, it is possible to change the 3D depth through scrolling.

More specifically, it is assumed that only the surface of the 3D depth layer object corresponding to the position of layer 1 is clearly displayed in the arrangement state of the layer objects as shown in FIG. 7A. Further, it is assumed that the surface of layer objects (ie, layer 2 and layer 3) located at a 3D depth deeper than the position of layer 1 is covered by the layer object (ie, layer 1) located at a lower 3D depth.

Under this assumption, as shown in FIG. 7B, the 3D depth may be lowered so as to feel closer to the user by scrolling all the layer objects through a predetermined operation through the user input unit.

In this case, layer 2 has a 3D depth corresponding to layer 1 in FIG. 7A, and layer 3 has a 3D depth corresponding to layer 2 in FIG. 7A. Here, since only the surface of the layer object located at the depth of layer 1 of FIG. 7A is clearly displayed, as shown in FIG. 7B, the surface of layer 2 is most clearly displayed, and the surface of layer 3 is shown in FIG. 7B. Is covered by the surface of layer 2.

Meanwhile, the layer 1 has a 3D depth lower than its position in FIG. 7A, and in this case, the controller 180 may make the layer 1 transparent or translucent as the layer 1 moves away from the 3D depth of the layer 2. .

Through the operation of the mobile terminal described above, the user can clearly see the surface of the layer 2 without disturbing the layer 1. If the user scrolls to deepen the 3D depth of all the layer objects again, the state will be as shown in FIG. 7A. If the user scrolls to lower the 3D depth of all the layer objects, both layer 1 and layer 2 are transparent. Alternatively, the surface of the layer 3 may be clearly displayed while becoming translucent.

Hereinafter, in this specification, 3D depth such that the surface of a layer object positioned at the corresponding depth, such as the 3D depth of layer 1, in FIG. It is called.

Hereinafter, a specific example in which the scroll operation of the stereoscopic user interface described with reference to FIG. 7 is applied to the menu operation of the mobile terminal will be described with reference to FIGS. 8 to 11.

8 illustrates an example of a menu list divided by layers of a stereoscopic user interface that may be implemented in a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 8, menus having horizontal relations are mapped to layer 1 and layer 2, respectively. In other words, the menus mapped to the layer 1 and the layer 2 are menus that can be selected independently of each other, not the upper menu and the lower menu.

A method of selecting a menu list by scrolling a layer in the mapping relationship as shown in FIG. 8 will be described with reference to FIG. 9.

9 is a conceptual view illustrating a menu selection through a stereoscopic user interface that may be implemented in a mobile terminal according to an embodiment of the present invention.

Since the basic assumption of FIG. 9 is similar to that of FIG. 7, redundant descriptions are omitted for simplicity of the specification. However, as shown in FIG. 8, icons corresponding to menus mapped to each layer are displayed on the surface of each layer object.

Referring to FIG. 9A, the menu icons (that is, the message, the phone book, the Internet, and the control panel) mapped to the layer 1 are clearly displayed while the layer 1 is located at the reference depth, and the layer 2 and the layer 3 are Covered with layer 1, the surface is invisible.

Here, the user may arrange layer 2 as a reference depth by lowering the 3D depth of all the layer objects (ie, appearing to be close to the user) through a predetermined scrolling operation.

Accordingly, as shown in (b) of FIG. 9, the layer 1 has a depth lower than the reference depth and becomes translucent, and as the layer 2 is positioned at the reference depth, menu icons mapped to the layer 2 (ie, game, music playback, Dictionary and alarm) can be displayed clearly. The surface of layer 3 is hidden by layer 2 and may still be invisible.

Next, a case where menus of vertical relations are mapped between layers will be described.

10 illustrates another example of a menu list divided by layers of a stereoscopic user interface that may be implemented in a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 10, vertical and hierarchical menus are mapped to layer 1 and layer 2, respectively. In other words, the menus mapped to Layer 1 and Layer 2 are the menus in the upper menu and lower menu relations.

A method of selecting a menu list by scrolling a layer in the mapping relationship as illustrated in FIG. 10 will be described with reference to FIG. 11.

11 is a conceptual view illustrating another example of menu selection through a stereoscopic user interface that may be implemented in a mobile terminal according to an embodiment of the present invention.

Since the basic assumption of FIG. 11 is also similar to that of FIG. 7, redundant descriptions are omitted for simplicity of the specification. However, as shown in FIG. 10, icons corresponding to menus mapped to each layer are displayed on the surfaces of the layer objects.

Referring to (a) of FIG. 11, the menu icons (that is, the message, the phone book, the Internet, and the control panel) mapped to the layer 1 are clearly displayed while the layer 1 is located at the reference depth, and the layer 2 and the layer 3 are Covered with layer 1, the surface is invisible.

In this case, the user selects the message icon 1100 through a predetermined command input and scrolls to lower the 3D depth of all the layer objects (that is, appear to be close to the user) to the reference depth. Can be placed.

Accordingly, as shown in (b) of FIG. 11, the layer 1 has a depth lower than the reference depth to become translucent, and as the layer 2 is located at the reference depth, icons corresponding to submenus of the message menu mapped to the layer 2 ( That is, the received message, message composition, voice message and message setting) can be clearly displayed. The surface of layer 3 is hidden by layer 2 and may still be invisible. Thereafter, the user may select one of the icons of the layer 2 and scroll again to view the sub-menu of the icon selected in the layer 2 through the layer 3 through scroll input.

The menu selection method described with reference to FIGS. 8 to 11 may be used as a method of selecting or searching a menu or an object having a parallel relationship or a parent relationship. For example, when the file browser function is executed, the upper folder displayed on the upper layer may be selected and scrolled to search the list of files included in the lower folder or the upper folder in the lower layer.

So far, the layers have been described based on a form disposed to overlap each other at a predetermined distance, but this is only an example, and the present invention is not limited thereto and may be applied to the arrangement form of various layers. This will be described with reference to FIG. 12.

12 illustrates examples of a layer arrangement form of a stereoscopic user interface that may be implemented through a display unit of a mobile terminal according to an embodiment of the present invention.

First, referring to FIG. 12A, two or more separate layers may be disposed at the same 3D depth, unlike the arrangement of the above-described layers, and the layer positioned at the top (ie, the layer having the lowest 3D depth) may be disposed. Is set as the reference layer. In this case, when the second 3D depth or the low layer object 1210 is moved to the top layer, the layer object 1220 that was previously on the top layer may be arranged to be pushed down to the layer below it. This layer arrangement can be used to move, rearrange menu icons, or stereoscopically display a photo (or a thumbnail thereof) on a photo album.

Next, referring to FIG. 12 (b), unlike the above-described layers having only 3D depths but arranged in parallel, angles may be arranged at an angle so that one layer has two or more 3D depths.

Referring to FIG. 12C, two layers 1230 and 1250 may be obliquely disposed on both sides of the layer 1240 at the deepest 3D depth in the center thereof.

In addition, as shown in the general user interface, an arbitrary display may be displayed through one layer, and a layer having a 3D depth different from that of the existing layer may be added and displayed in a popup form according to the occurrence of a click or an event. Referring to FIG. 12 (d), only the notepad 1270 of the eight icons arranged on the screen is displayed on a layer having a lower 3D depth to protrude from the user's gaze. At this time, when the user selects the calendar icon 1280 next to the notepad icon 1270, the notepad icon 1270 is rearranged to the existing layer, and the calendar icon 1280 has a 3D depth lower than that of the existing layer. It can be placed on a layer of. In this case, when each icon is popped up and displayed with a layer having a lower 3D depth than the existing layer, the size thereof may be enlarged, and thus may be changed to display detailed information when the icon is located on the existing layer. have.

Second embodiment

Hereinafter, a method of controlling a stereoscopic user interface using a plurality of layer objects according to the first embodiment of the present invention described above will be described.

Referring to FIG. 13, an example of a method of scrolling layers when the 3D depth of the entire plurality of layers is changed by one selection as in FIG. 9 described above is described.

13 illustrates an example of a method of selecting or scrolling a plurality of layers in a stereoscopic user interface according to another embodiment of the present invention.

In the stereoscopic user interface environment according to the present invention, the mobile terminal 100 for scrolling a plurality of layers includes two hardware key buttons 132a and 132b on one surface or (b) of FIG. 13 as shown in FIG. Likewise, two virtual key buttons 1300 and 1305 may be provided on the display unit 151.

As shown in FIG. 9, in FIG. 13C, three layers 1310, 1320, and 1330 having different 3D depths are arranged in parallel, and the middle layer 1320 is located at a feeling depth. Assume In this case, when the key buttons 132a or 1305 mapped in the downward direction are manipulated by the user, the layers may be scrolled downward based on the reference depth as shown in the left side of FIG. 13C. On the contrary, when the key button 132b or 1300 mapped to the upward direction is manipulated by the user, the layers may be scrolled upward based on the reference depth as shown in the right side of FIG.

At this time, the degree of scrolling may be changed in units of a predetermined distance in proportion to the time when each key button is operated, or changed as much as one layer interval in one operation (that is, the next-order layer of the layer located at the current reference depth). May be moved directly to the reference depth).

In addition, instead of scrolling the layer through the same operation, only the selected layer (or the activated layer) may be changed while maintaining the arrangement of the layer. In this case only the selected layer is clearly displayed and the layers that are not may have a transparent or translucent effect.

In addition, in the case of having a layer arrangement form as shown in (a) or (b) of FIG. 12, the arrangement may be performed by simply selecting an object to be placed as the top layer or inputting a touch-drag operation through a touch screen in an arbitrary direction. can be changed.

Next, a method of scrolling or selecting a layer using proximity of a pointer will be described with reference to FIG. 14.

Up to three steps) can be provided with a touch screen that can be recognized. In this case, the stereoscopic user interface according to the present invention may be manipulated according to the distance of the user's pointer (finger or stylus pen) from the touch screen.

More specifically, when the pointer is located in the period d2 to d3, as shown in FIG. 13, as shown in FIG. 13, the key buttons 132b or 1300 are manipulated by the user, so that the layers are upwards based on the reference depth (ie, 3D). Scroll in the direction of decreasing depth). In addition, when the pointer is located in the period d1 to d2, the layers may be scrolled downward based on the reference depth as shown in FIG. 13 as the key button 132a or 1305 mapped to the downward direction is operated by the user. . When the pointer directly touches the touch screen, the controller 180 may recognize that an icon or menu selection command corresponding to a touch point is input.

Next, as shown in FIG. 14B, the proximity distance of the pointer may be recognized through a separate sensing device 1410 instead of the touch screen. In this case, as the sensing device 1410, a proximity sensor 141 or a camera 121 may be used.

Meanwhile, as described above, when the proximity distance of the pointer is recognized as a user's command input, a malfunction may occur in a process of moving the pointer to a desired depth of proximity, and thus, only when the pointer stays at a specific distance for a predetermined time or more. A command corresponding to may be performed.

Hereinafter, a specific form to which the above-described stereoscopic user interface is applied will be described.

In this case, the selected text input field 1510 and the corresponding virtual keypad 1530 may be displayed to have a lower 3D depth (that is, protruding to the user) than the area excluding them.

In addition, when another text input window 1520 is selected as shown in FIG. 15B, when the virtual keypad 1530 is displayed, the text input window may be covered by the virtual keypad. In this case, as shown in FIG. 15B, the web page may be appropriately scrolled so that the text input window 1520 is not covered by the virtual keypad automatically. Alternatively, a method of providing a low 3D depth only to an area corresponding to the virtual keypad and processing the virtual keypad translucently may be used.

FIG. 16 illustrates an example of a method for automatically generating an object having a different 3D depth when a preset condition is satisfied.

Referring to FIG. 16, it is assumed that weather information is displayed on a display unit of a mobile terminal, and weather information is updated in real time or at a predetermined cycle. In this case, when the temperature information is updated, the updated information 1610 may be provided with a lower 3D depth than the surroundings so as to protrude to the user. In this way, the user can easily recognize whether or not the information is updated. Here, the weather information is an example, and the method of displaying the update information may be used for notifying a reception of a new message or the arrival of a preset alarm time.
