Description

Method, device and system for evaluating multimedia file

Technical Field

The present application relates to the field of information processing and terminal technologies, and in particular, to a method, an apparatus, and a system for evaluating multimedia files.

Background

With the rapid development of internet technology, services provided by computer devices for users are more and more diversified, for example, the computer devices can play multimedia files such as movies, television shows, etc. for users, so as to meet entertainment demands of users. Typically, the user selects a multimedia file for viewing in dependence on other user ratings of the multimedia file, and in addition, the user ratings of the multimedia file may also facilitate optimization of the multimedia file by the merchant. Therefore, the evaluation of multimedia files by users plays an important role in the internet field.

At present, two modes of questionnaire investigation and audio-visual effect collection exist. When a user's evaluation of a multimedia file is obtained by using a questionnaire, the user's feeling may change with time due to the time lag of the questionnaire compared with the playing time of the multimedia file, and in addition, whether the user actually views the multimedia file cannot be guaranteed. Therefore, the accuracy and fairness of the results of the questionnaire are not high. The video-audio effect collection relies on expensive video-audio effect information collection systems, such as acoustic collection devices deployed in movie theatres, to collect the visual impact of the audience, such as cheering, and analyze the audience's performance to obtain user ratings for multimedia files. The video and audio effect acquisition mode is limited by scene and equipment cost, so that the video watching cost of users is improved, the accuracy is limited, and corresponding evaluation cannot be acquired for each user.

How to timely, conveniently and efficiently obtain accurate and objective evaluation of a user on a multimedia file is a problem to be solved currently.

The wearable device 100 starts the "movie watching mode" under the trigger of the user operation.

The user operation for turning on the "movie mode" of the wearable device 100 may be an operation acting on the electronic device 200.

Illustratively, referring to fig. 5A, fig. 5A shows a user interface 50 displayed on an electronic device 200. The user interface 50 may be provided by an application installed on the electronic device 200 for managing a wearable device connected to the electronic device 200, such as a hand loop management application, or a "setup" application on the electronic device 200.

As shown in fig. 5A, user interface 50 may include a status bar 501, a return key 502, a current page indicator 503, a device status display area 504, controls 505, and other controls for opening corresponding functions of wearable device 100.

The return key 502 is an APP level return key that can be used to return to the menu upper level. Those skilled in the art will appreciate that the logical level of a page is fixed and is determined at the time of application design.

The current page indicator 503 may be used to indicate a current page, e.g., the text message "Hua as a bracelet" may be used to indicate that the current page is used to manage a wearable device to which the electronic device 200 is connected. Not limited to text information, the current page indicator 503 may also be an icon.

The device status display area 504 is used to display status information of the wearable device 100 connected to the electronic device 200, and may include, for example, a connection manner (such as a bluetooth icon shown in the drawing) of the wearable device 100 and the electronic device 200, a remaining power of the wearable device 100, a picture of the wearable device 100, and the like.

Control 505 may be used to monitor for user operations (e.g., touch operations, click operations, etc.), and in response to user operations acting on control 308, electronic device 200 may send a notification message to wearable device 100 through a connection with wearable device 100 to notify or instruct wearable device 100 to turn on a "movie mode". In some embodiments, referring to fig. 5B, after electronic device 200 detects a user operation on control 308, the display form of control 308 may also be altered to prompt the user that wearable device 100 has been turned on "movie mode".

It is understood that the user operation shown in fig. 5A and 5B that triggers the wearable device 100 to enter the "movie mode" on the electronic device 200 is only an example, and the user operation may be implemented in other manners. For example, the user operation may also be a click operation detected by the electronic device 200 after a downward swipe gesture at the status bar 501, popup the window and on a "view mode" switch control in the window.

Not limited to the operation on the electronic device 200, the user operation for turning on the "movie mode" of the wearable device 100 may also be an operation acting on the wearable device 100. For example, the user operation may be a double click operation on a physical key (e.g., a power key) of the wearable device 100, an operation on a switch control of "movie mode" in a user interface displayed on a display screen of the wearable device 100, or an operation to shake the wearable device 100, and the like, to which the embodiment of the present application is not limited.

In the embodiment of the present application, an operation for turning on the "movie mode" of the wearable device 100, which acts on the electronic device 200, may be referred to as a first operation.

In the embodiment of the present application, an operation for turning on the "movie mode" of the wearable device 100, which acts on the wearable device 100, may be referred to as a fourth operation.

And (II) the wearable device 100 automatically starts a 'viewing mode' when recognizing that the user is in a scene of watching the multimedia file, and no user operation is needed.

Through the second mode of automatically starting the "movie watching mode", the wearable device 100 can automatically generate a corresponding evaluation result for the user when the user watches the multimedia file, so that the method is simpler and more convenient for the user.

In the embodiment of the present application, the wearable device 100 may detect the environmental data and determine whether the current user is in a scene of viewing the multimedia file according to the environmental data. Specifically, the wearable device 100 may collect sound in the surrounding environment through the microphone, collect light and shadow through the ambient light sensor, collect images through the camera, and other environmental data, and determine whether to view the scene of the multimedia file for the user currently according to the data.

In some embodiments, the wearable device 100 may also search from the network according to the collected data to obtain related information of the multimedia file watched by the user. In an embodiment of the present application, the related information of the multimedia file may include, but is not limited to, a name, a duration, a content profile, a main creation information of the multimedia file, a time node of the multimedia file currently being played, and the like.

In some embodiments, the wearable device 100 may also send the acquired related information of the multimedia file to the electronic device 200.

It can be appreciated that the second mode is applicable to any of the scenes where the user views the multimedia file, for example, where the user views the multimedia file played by the electronic device 200, or where the user views the multimedia file played by the large-screen device 300.

And (III) upon identifying that the user is in a scene of viewing the multimedia file, the electronic device 200 notifies the wearable device 100to turn on the "viewing mode".

Specifically, the electronic device 200 may identify whether the current user is in a scene of viewing the multimedia file, and transmit a notification message to the wearable device 100 in case it is determined that the current user is in a scene of viewing the multimedia file. The notification message is used to notify the wearable device 100 to turn on the "movie mode".

After receiving the notification message, the wearable device 100 may turn on the "movie mode". In connection with 3 different scenarios, how the electronic device 200 recognizes whether the current user is in a scenario of viewing a multimedia file is described in detail below. In this way, when the user is in a scene of watching the multimedia file, the wearable device 100 can start the "movie watching mode" under the trigger of the electronic device 200, so that the user operation is not required, and the method is more concise and convenient for the user.

(1) In a scenario in which the electronic device 200 plays the multimedia file, the electronic device 200 may directly recognize that it is currently playing the multimedia file, thereby determining that the current user is in a scenario in which to view the multimedia file. Here, the multimedia file played by the electronic device 200 may be a local file or an online file.

In some embodiments, the electronic device 200 may also obtain information about the currently playing multimedia file. The related information of the multimedia file may be referred to the previous related description. Specifically, when the electronic device 200 plays the local file, the related information of the multimedia file may be stored in the electronic device 200, and the electronic device 200 may directly obtain the related information of the multimedia file. When the electronic device 200 plays an online file, the electronic device 200 may obtain information about the multimedia file from a network (e.g., at a video server that provides the online file).

In some embodiments, the electronic device 200 may also send the acquired information about the currently playing multimedia file to the wearable device 100.

Referring to fig. 5C, fig. 5C illustrates a flow of informing the wearable device 100to turn on the "movie mode" after the electronic device 200 determines that the current user is in a scene of viewing the multimedia file through the (1) th mode.

(2) In a scene where the large-screen device 300 (e.g., television, projector, etc.) plays a multimedia file, the electronic device 200 can learn, through a connection with the large-screen device 300, that the large-screen device 300 is currently playing the multimedia file, thereby determining that the current user is in a scene of viewing the multimedia file. Here, the multimedia file played by the large screen apparatus 300 may be a local file or an online file.

In some embodiments, the electronic device 200 may also obtain information about the multimedia file currently being played by the large screen device 300. The related information of the multimedia file may be referred to the previous related description.

When the large screen device 300 plays the local file, the related information of the multimedia file may be stored in the large screen device 300, and the electronic device 200 may obtain the related information of the multimedia file from the large screen device 300 through a connection with the large screen device 300.

When the large screen device 300 plays the online file, if the online file is obtained from the network by the large screen device 300, the large screen device 300 may also obtain the relevant information of the multimedia file from the network (such as a video server that provides the online file) and send the relevant information to the electronic device 200. If the online file is obtained by the electronic device 200 from the network (e.g., at a video server providing the online file) and sent to the large screen device 300, the electronic device 200 may obtain the relevant information of the multimedia file directly from the network (e.g., at the video server providing the online file).

In some embodiments, the electronic device 200 may also send the acquired information about the multimedia file played by the current large-screen device 300 to the wearable device 100.

Referring to fig. 5D, fig. 5D illustrates a flow of informing the wearable device 100to turn on the "viewing mode" after the electronic device 200 determines that the current user is in a scene of viewing the multimedia file through the (2) th mode.

(3) In a scenario where the large screen device 300 (e.g., an audio-visual device in a movie theater, etc.) plays a multimedia file, the electronic device 200 may learn, in conjunction with the location, ticket booking information of the user, etc., that the current user is in a scenario of viewing the multimedia file.

For example, the electronic device 200 may acquire geographical location information where the current user is located, and if the current user is in a movie theater and the ticket booking information of the user indicates corresponding movie information such as a name of a movie, an open time, etc., the electronic device 200 may determine that the current user is in a scene of viewing the multimedia file. The ticket booking information for the user may be stored locally on the electronic device 200, e.g., the ticket booking information for the user may be in a text message on the electronic device 200. The ticket booking information of the user may also be obtained by the electronic device 200 from the network, for example, the electronic device 200 may obtain the ticket booking information of the user from the network through ticket booking software.

In some embodiments, the ticket booking information for the user includes information regarding the multimedia file currently being played by the large screen device 300. In some embodiments, the electronic device 200 may also search the network for information about the multimedia file currently played by the large screen device 300 according to the acquired ticket booking information.

In some embodiments, the electronic device 200 may also send the searched related information of the multimedia file played by the current large-screen device 300 to the wearable device 100.

Referring to fig. 5E, fig. 5E illustrates a flow of informing the wearable device 100to turn on the "movie mode" after the electronic device 200 determines that the current user is in a scene of viewing the multimedia file through the (3) th mode.

(4) The electronic device 200 may detect the environmental data and determine whether the current user is in a scene of viewing the multimedia file according to the environmental data.

Specifically, the electronic device 200 may collect sound in the surrounding environment through a microphone, collect light and shadow through an ambient light sensor, collect images through a camera, and other environmental data, and determine whether to view the scene of the multimedia file for the user currently according to the data.

In some embodiments, the electronic device 200 may also search from the network according to the collected data to obtain relevant information of the multimedia file watched by the user. In an embodiment of the present application, the related information of the multimedia file may include, but is not limited to, a name, a duration, a content profile, a main creation information of the multimedia file, a time node of the multimedia file currently being played, and the like.

In some embodiments, the electronic device 200 may also send the acquired information about the multimedia file to the wearable device 100.

It will be appreciated that the above-described ways of identifying whether the current user is in a scene of viewing the multimedia file by the electronic device 200 of (1) - (4) can be implemented in combination, and the embodiment of the present application is not limited thereto.

It can be appreciated that when the "viewing mode" is turned on in the second or third manner, the wearable device 100 may also ask the user whether to turn on the "viewing mode" of the wearable device 100 before the "viewing mode" is turned on, and may turn on the "viewing mode" of the wearable device 100 after the user confirms that the "viewing mode" is turned on. By the method, more selectivity and awareness can be given to the user, and user experience can be improved.

After the wearable device 100 starts the "movie mode", an icon of the movie mode may be displayed on the display screen, for prompting the user that the "movie mode" is currently started. Referring to fig. 6A and 6B, fig. 6A illustrates a user interface 60 displayed by the wearable device 100 when locked. An icon 601 of the viewing mode is included in the user interface 60 for indicating that the "viewing mode" is currently turned on. Fig. 6B illustrates a main interface 61 displayed after the wearable device 100 is unlocked, where the user interface 61 includes icons of one or more applications installed on the wearable device 100, such as an icon of an instant messaging application, an icon of an application market, an icon of an address book, an icon 602 of a "view mode" may be displayed in the user interface 61 after the wearable device 100 is turned on the "view mode", and so on. The icons 601 and 602 of the "movie mode" may be used to monitor a user operation, and the electronic device 200 may display experience data of the user collected by the wearable device 100 in response to the user operation, and the description of the embodiments will be omitted herein.

In the case where the "movie mode" of the wearable device 100 is on, and the user is in a scene of viewing a multimedia file, the wearable device 100 may collect experience data when the user views the multimedia file.

After the wearable device 100 starts the "movie watching mode" through the above (first) manner, that is, under the trigger of the user operation, the wearable device 100 may collect experience data when the user views the multimedia file after determining that the user is in a scene of viewing the multimedia file. The manner in which the wearable device 100 determines that the user is in a scene of viewing the multimedia file may include two types of:

(1) The wearable device 100 may autonomously recognize whether the user is in a scene of viewing the multimedia file. Reference may be made specifically to the description related to the wearable device 100 in the above (second) manner as to whether the user is in a scene of viewing the multimedia file.

(2) The electronic device 200 may send a notification message to the wearable device 100 after determining that the current user is in a scene of viewing the multimedia file, so that the wearable device 100 knows that the current user is in a scene of viewing the multimedia file. Here, the electronic device 200 determines a manner in which the user is viewing the scene of the multimedia file, and reference is made to the related description in the above-described (third) manner.

It can be appreciated that, when the wearable device 100 determines that the user is in the scene of watching the multimedia file in the above (1) or (2), the related information of the multimedia file may also be obtained, and reference may be made to the related descriptions in the above (second) or (third) modes.

When the wearable device 100 starts the "viewing mode" in the second or third mode, because the user is already in the scene of watching the multimedia file before the wearable device 100 starts the "viewing mode", the wearable device can directly collect the experience data when the user watches the multimedia file after starting the "viewing mode".

In embodiments of the present application, wearable device 100 may continuously or periodically collect the experience data, without limitation. When the wearable device 100 periodically collects experience data, the processing pressure of the wearable device 100 can be reduced, and power consumption is saved.

In embodiments of the present application, experience data of a user viewing a multimedia file may include, but is not limited to, one or more of sign data, action data, sound data, etc. of the user viewing the multimedia file. The sign data may include one or more of blood glucose, heart rate, blood pressure, body surface temperature, skin conductance signals, eye movement signals, or brain microcurrent signals. The motion data may include one or more of hand motion, limb motion, torso motion, head motion, and the like. The sound data may include voiceprints, intonation, mood, language, etc. of the sound. Specifically, the wearable device 100 may collect acceleration through an acceleration sensor, collect angular velocity through a gyro sensor, collect a blood glucose value of a user through a blood glucose sensor, collect a blood pressure value of the user through a blood pressure sensor, collect a heart rate of the user through an electrocardio sensor, collect a conductive value of skin of the user through a myoelectric sensor, collect a body surface temperature of the user through a body temperature sensor, collect a micro-current value of brain of the user through a brain wave sensor, collect a vibration signal through a bone sensor, collect a sound of the user through a microphone, and the like.

In embodiments of the present application, wearable device 100 may record or store the collected experience data. In some embodiments, the wearable device may store the collected experience data in association with the time node of the multimedia file viewed by the current user, which may facilitate the accuracy of the subsequent generation of the user's evaluation result of the multimedia file.

In some embodiments of the application, wearable device 100 may display these experience data on a display screen when the user needs to view them. In addition, the wearable device 100 may display related information of the acquired multimedia file, such as a type, a name, etc., of the multimedia file on the display screen.

For example, referring to fig. 6A, 6B, and 6C, when the wearable device 100 detects a user operation acting on the icon 601 or 602 of the "movie mode", the user interface 62 may be displayed in response to the user operation.

In one possible implementation, as shown in fig. 6C, the user interface 62 displays experience data of the user collected by the wearable device 100, and the name of the multimedia file. In some embodiments, these experience data may be displayed in different time nodes. That is, the wearable device 100 may display the experience data collected at different time points, respectively.

In another possible implementation, as shown in fig. 6D, the user interface 62 may not directly display the experience data collected by the wearable device 100, but display the analyzed data, such as the emotion change condition of the user, the limb action condition, such as the number of times the user is in various emotions, the duration, the emotion at a specific point in time when the user views the multimedia file, and so on, according to the collected experience data. In addition, the name of the multimedia file, such as the movie "Tetank number", may also be displayed in the user interface 62. Here, the wearable device 100 may analyze the experience data according to a pre-stored or big data training learning analysis model or algorithm to obtain the emotion change condition of the user, where the analysis model and algorithm may be obtained by depending on the sign data, the action data, and the correspondence between the sound data and the emotion of the user. Referring to table 1, table 1 exemplarily shows a possible correspondence between experience data and emotion of a user.

Experience data	Mood of emotion
		Sound data characterizing large changes in user emotion	Active input of
Sound data characterizing little change in emotion of user	Calm and no interest
		Motion data characterizing user limb motion frequency	Active input of
Motion data characterizing less motion of a user's limb	Calm and no interest
		The heart rate is continuously higher than Yu Jing resting heart rate by 30 percent and is stable	Excited, sensitive and dynamic
Heart rate variation of less than 5%	Calm and no interest
		The skin impedance is reduced by more than 30 percent	Easy and pleasant
The skin impedance is reduced by less than 5 percent	Not of interest
		The blood pressure is continuously 30 percent higher than the basic blood pressure	Tension, input
The blood pressure change is lower than 5%	Calm and no interest

TABLE 1

It can be appreciated that by displaying the experience data of the user on the wearable device 100, the user can grasp his own experience in real time in the process of watching the multimedia file, and the user experience is improved. Not limited to displaying the user's experience data on the wearable device 100, in some embodiments, the wearable device 100 may send the collected experience data to the electronic device 200 after the collected experience data, and the electronic device 200 displays the experience data or displays the analyzed data, which will be described in detail in the following embodiments, which will not be described herein.

In the embodiment of the present application, after acquiring the experience data when the user views the multimedia file, the wearable device 100 or the electronic device 200 may generate the evaluation result of the user on the multimedia file. In the following, the method of generating the evaluation result by the wearable device 100 by using the user to generate the multimedia file is described as an example, and the manner of generating the evaluation result by the electronic device 200 is the same as that, and will not be described in detail later.

In some embodiments, the wearable device 100 may generate a user's evaluation result of the multimedia file in response to a user operation when the user operation is received. Illustratively, referring to FIG. 6C or FIG. 6D, a control 603 may also be included in the user interface 62. The wearable device 100 may generate a user's evaluation result of the multimedia file in response to a user operation (e.g., a click operation, a touch operation, etc.) detected on the control 603. The user operation may be input by the user at any time when viewing the multimedia file. That is, the evaluation result of the multimedia file generated in the embodiment of the present application may be a part or all of the evaluation result of the multimedia file.

In other embodiments, the wearable device 100 may autonomously generate the user's evaluation result of the multimedia file when the user exits from viewing the multimedia file or when the user has finished viewing the multimedia file. The wearable device 100 may determine whether the user exits from viewing the multimedia file or has completed viewing the multimedia file by first detecting sound data by the wearable device 100 and determining whether the current user exits from viewing the multimedia file or has completed viewing the multimedia file according to the sound data. In the second way, the wearable device 100 knows from the electronic device 200 whether the current user exits from viewing the multimedia file or has completed viewing the multimedia file. In one embodiment, the electronic device 200 may send information about the multimedia file to the wearable device 100 when playing the multimedia file, so that the wearable device 100 knows the playing condition of the multimedia file. In another embodiment, the electronic device 200 may combine the location, the ticket booking information of the user, the information of the multimedia file, and the like to obtain the time when the user has finished viewing the multimedia file, so as to determine whether the current user has finished viewing the multimedia file. When the wearable device autonomously generates the evaluation result of the user on the multimedia file, the user does not need to intervene, so that the user operation can be simplified, and the user experience can be improved.

Specifically, in the embodiment of the present application, the wearable device 100 may generate the evaluation result of the user on the multimedia file according to the acquired experience data and the evaluation policy when the user views the multimedia file. Wherein the evaluation policy indicates an association relationship or association criterion of the experience data and the evaluation result, in other words, the evaluation policy indicates a correspondence relationship between the experience data and the user's experience on the multimedia file. In general, the higher the interaction frequency between the user and the wearable device 100, the longer the interaction time, the higher the satisfaction of the user with the multimedia file.

Illustratively, referring to Table 2, table 2 shows one possible evaluation strategy. In the evaluation strategies shown in table 2, the evaluation results of the multimedia files by the users are measured by scores, and the higher the total score is 10 scores, the higher the satisfaction degree of the users on the multimedia files is indicated. Table 2 gives a corresponding score specification and weight for each item of experience data, respectively. After the experience data of the user is obtained, weighting calculation can be performed on each item of experience data according to table 2, so that the total score of the user on the multimedia file is obtained.

TABLE 2

For example, if the wearable device 100 collects the experience data of a user watching multimedia information, the scores corresponding to each item in table 2 are 10, 9, 8 and 7, and according to the evaluation policy shown in table 2, the wearable device may generate the evaluation result of the user on the multimedia file according to the following formula (10×3+10×3+9×2+7×1+8×1)/10=9.3).

The evaluation policies shown in table 2 are merely examples, and in a specific implementation, the evaluation policies according to which the wearable device 100 generates the multimedia file by the user may also be implemented in other forms, and the following is a few possible cases.

In some embodiments of the application, the assessment policy may also be personalized based on one or more of the user's gender, age, and constitution. For example, when the experience data includes skin impedance, the rate of change of skin impedance measured at the same emotion or satisfaction is different for female users and male users, or users of different ages. To compensate for this difference in gender of the user, this difference data may be obtained from a large amount of experimental data, with different scoring specifications set for users of different gender for this item of experience data of skin impedance. In other words, in the embodiment of the application, different evaluation strategies can be used for different users to obtain the evaluation result of the user on the multimedia file, so that the obtained evaluation result is more fit with the actual situation of each user, more accords with the actual experience of the user, and has objectivity and authenticity.

In the embodiment of the present application, the wearable device 100 may store the evaluation policy in advance, may periodically acquire an updated evaluation policy from the network, and may correct the evaluation policy according to the actual situation of the user, which is not limited in the embodiment of the present application.

In the embodiment of the application, the evaluation result is not limited to the score, and can be realized in other forms, such as a symbol (e.g. a star symbol), an expression package, a text, an audio/video (e.g. an movie comment) and the like. For example, the wearable device 100 may further determine keywords (such as "feeling", "fun", "burn" and the like) that may be used to describe the experience or emotion of the user viewing the multimedia file according to the collected experience data and the evaluation policy when the user views the multimedia file, and use these keywords as the evaluation result. As another example, the wearable device 100 may further determine keywords (such as "comedy", "patriot", "love", "relatedness", etc.) for describing the multimedia file from the network according to the related information of the multimedia file, and automatically generate a piece of text in combination with the keywords for describing the experience or emotion of the user viewing the multimedia file. For another example, the wearable device 100 may collect an audio/video when the user views the multimedia file, or collect a section of audio/video recorded after the user views the multimedia file and used for evaluating the multimedia file, and take the audio/video as the evaluation result of the user on the multimedia file.

In practical applications, the wearable device 100 may also generate corresponding evaluation results for different time periods (for example, 10 minutes before the start, 20 minutes in the middle, or 5 minutes before the end) of the multimedia file, or for a time period including a specific lead actor (for example, a time period including star a) in the multimedia file. Therefore, the wearable device 100 may generate the evaluation result corresponding to the preset time period according to the acquired experience data of the user when the user views the information of the preset time period in the multimedia. Therefore, the flexibility of the evaluation result can be improved, and the user experience is improved.

In some embodiments of the present application, referring to fig. 6E, the wearable device 100 may also display a user interface 63 in the process of generating the evaluation result, prompting the user that the evaluation result is currently being generated, giving the user a better use experience.

In the embodiment of the present application, after the wearable device 100 generates the evaluation result according to the acquired experience data when the user views the multimedia file, the evaluation result may be displayed on the display screen.

In some embodiments, the wearable device 100 may display the generated evaluation result on the display screen in response to a user operation when the user operation is received. Illustratively, referring to fig. 6F, after generating the evaluation result, wearable device 100 may display user interface 64 on a display screen, and control 604 may be included in user interface 64. Referring to fig. 6F and 6G, the wearable device 100 may display the generated evaluation results in the user interface 64 in response to a user operation (e.g., a click operation, a touch operation, etc.) detected on the control 604.

In other embodiments, the wearable device 100 may also display the evaluation result directly on the display screen after generating the evaluation result. For example, the wearable device 100 may directly display the user interface as shown in fig. 6G after generating the evaluation result. By the method, user intervention is not needed, user operation can be simplified, and user experience is improved.

In an embodiment of the present application, the wearable device 100 may also modify or correct the generated evaluation result in response to a user operation. That is, after seeing the evaluation result displayed on the display screen of the wearable device 100, the user can modify the evaluation result by the user operation according to the self-demand. For example, referring to fig. 6G, a control 605 may also be included in the user interface 65, and the wearable device 100 may display a page for the user to modify the rating result and receive an operation for the user to change the rating result in response to a user operation received on the control 605. For example, when the evaluation result is a score, the user may increase or decrease the score. For another example, when the evaluation result is text, the user may add keywords to the text. The mode of modifying the evaluation result by the user is not particularly limited in the embodiment of the application. Through the correction of the evaluation result by the user, the final obtained evaluation result is consistent with the actual experience of the user, and the authenticity of the evaluation result is improved.

In the embodiment of the application, the user can share the related information and the evaluation result of the multimedia file to a website, friends in instant messaging software and the like through the wearable device 100. The evaluation result may be an evaluation result generated by the wearable device 100 or an evaluation result corrected by the user, which is not limited herein. Websites may include social networking websites, critique websites, video websites, and so forth.

Illustratively, referring to FIG. 6G, a control 606 for sharing relevant information and evaluation results of the multimedia file to a website or friend may also be included in the user interface 65. In response to an operation (e.g., touch operation, click operation) received on control 606, wearable device 100 may display widget 607 in user interface 65. Referring to FIG. 6H, the widget 607 may include icons for one or more applications, such as icons 607A, 607B, 607C. In some embodiments, in response to an operation (e.g., touch operation, click operation) detected on an icon of an application, the wearable device 100 may share relevant information and evaluation results of the multimedia file to a website or friend. By way of example, referring to fig. 6I, fig. 6I illustrates one possible user interface 66 displayed on a display screen after the wearable device 100 shares relevant information and evaluation results of a multimedia file to a website, which user interface 66 may be provided by a video-like application "hua video". Not limited to the user operation received on the application icon, the wearable device 100 may also share related information and evaluation results of the multimedia file to a website or a net friend in response to other forms of user operation, which the embodiment of the present application does not limit.

As can be seen from the examples shown in the embodiments of fig. 6A to 6I, the method for evaluating a multimedia file according to the embodiment of the present application can generate an evaluation result of each user on the multimedia file according to real-time sense of reality of the user, where the evaluation result is objective, accurate, real and fair. In addition, the method is low in cost, is not limited to scenes, is convenient to implement, and is simple and convenient for users.

In the embodiment of the application, after sharing the evaluation result of the multimedia file, the user can conveniently know the multimedia file by other users. In addition, after the evaluation result of the user on the multimedia file is shared to the website, the merchant of the multimedia file can clip and correct the multimedia file according to the evaluation result of the user, so that the user experience is improved. In addition, after the website receives the evaluation result of the user on the multimedia file, the preference of the user can be analyzed in a big data analysis mode and the like, namely, a user image is generated for the user, and the user can be recommended with proper content according to the user image, so that the user experience is improved. For example, assuming that the video application (such as hua is a video) receives the evaluation results of the user on the plurality of multimedia files and analyzes that the user is interested in comedy, the relevant content of comedy can be recommended to the user when the user uses the video application next time and enters into the viewing mode.

It will be appreciated that fig. 6C-6I above mainly describe a user interface implemented on the wearable device 100, and that in practical applications, some of the operations mentioned in the above embodiments may also be performed by the electronic device 200. Some of the operations that may be performed by the electronic device 200 are briefly described below in connection with a user interface implemented on the electronic device 200.

Referring to fig. 7A-7E, a user interface displayed on a display screen of the electronic device 200 is illustrated.

In some embodiments of the present application, after the "movie viewing mode" of the wearable device 100 is turned on, the wearable device 100 may collect experience data when the user views a multimedia file when determining that the user is in a scene of viewing the multimedia file, and send the collected experience data to the electronic device 200.

The wearable device 100 may also obtain information about the multimedia file viewed by the user. The manner in which the wearable device 100 obtains the relevant information of the multimedia file may refer to the relevant descriptions in the (second) and (third) manners above.

In some embodiments of the present application, after the electronic device 200 receives the experience data sent by the wearable device, the experience data may be displayed on a display screen.

For example, referring to fig. 7A and 7B, after receiving experience data sent by wearable device 100, electronic device 200 may add display area 506 in user interface 50. In one possible implementation, referring to fig. 7A, the display area 506 displays experience data of the user collected by the wearable device 100, and related information (e.g., type, name, etc.) of the multimedia file. In some embodiments, these experience data may be displayed in different time nodes. In another possible implementation, the experience data collected by the wearable device 100 may not be directly displayed in the display area 506, but the data obtained after analysis processing may be displayed, for example, the emotion change condition of the user, the limb action condition, such as the number of times the user is in various emotions, the duration, the emotion at a specific time point of viewing the multimedia file, and so on, which are obtained according to the collected experience data. Here, the manner in which the electronic device 200 analyzes the experience data to obtain the emotion is the same as the manner in which the wearable device 100 analyzes the experience data to obtain the emotion described above, and reference may be made to the related description.

In some embodiments of the present application, after the electronic device 200 obtains the experience data of the user when viewing the multimedia file, the evaluation result of the user on the multimedia file may be generated. The manner in which the electronic device 200 generates the evaluation result is the same as the manner in which the wearable device 100 generates the evaluation result of the user on the multimedia file, and the foregoing related description may be referred to.

In some embodiments, the electronic device 200 may generate a user's evaluation result of the multimedia file in response to a user operation when the user operation is received. For example, referring to fig. 7A or 7B, a control 506A may also be included in the region 506. The electronic device 200 can generate a user's evaluation of the multimedia file in response to a user operation (e.g., a click operation, a touch operation, etc.) detected on the control 506A.

In other embodiments, the electronic device 200 may autonomously generate the user's evaluation result of the multimedia file when the user exits from viewing the multimedia file or when the user has finished viewing the multimedia file.

The manner in which the electronic device 200 generates the result of the user's evaluation of the multimedia file is the same as that in which the wearable device 100 generates the result of the user's evaluation of the multimedia file, and the foregoing related description may be referred to.

In some embodiments of the present application, referring to fig. 7C, the electronic device 200 may further display, in the area 506, a prompt message in the process of generating the evaluation result, for prompting the user that the evaluation result is currently being generated, so as to give the user a better use experience. The prompt may be implemented as an icon, text, or other form, to which embodiments of the application are not limited.

In the embodiment of the present application, after the electronic device 200 generates the evaluation result according to the acquired experience data when the user views the multimedia file, the evaluation result may be displayed on the display screen.

In some embodiments, the electronic device 200 may display the generated evaluation result on the display screen in response to a user operation when the user operation is received. Illustratively, referring to fig. 7D, after generating the evaluation result, the electronic device 200 can display a control 506B in the region 506. Referring to fig. 7E, the electronic device 200 may display the generated evaluation result in the region 506 in response to a user operation (e.g., a click operation, a touch operation, etc.) detected on the control 506B. Without limitation, in other embodiments, the evaluation result may not be displayed in the area 506 of the user interface 50, but may be displayed in other interfaces, as the embodiments of the present application are not limited in this respect.

In other embodiments, the electronic device 200 may also display the evaluation result directly on the display screen after generating the evaluation result. For example, the electronic apparatus 200 may directly display the user interface as shown in fig. 7E after generating the evaluation result. By the method, user intervention is not needed, user operation can be simplified, and user experience is improved.

In an embodiment of the present application, the electronic device 200 may also modify or correct the generated evaluation result in response to a user operation. Illustratively, referring to FIG. 7E, a control 506C may also be included in the user interface 50, and the electronic device 200 may display a page for the user to modify the rating result and receive a user operation for modifying the rating result in response to a user operation received on the control 506C. The manner in which the user modifies the evaluation result on the electronic device 200 is not particularly limited in the embodiment of the present application. In the embodiment of the present application, the user operation for modifying or correcting the evaluation result may be referred to as a third user operation.

In the embodiment of the present application, the user may share the related information and the evaluation result of the multimedia file to a website, friends in the instant messaging software, and so on through the electronic device 200. The evaluation result may be an evaluation result generated by the electronic device 200 or an evaluation result corrected by the user, and is not limited thereto. For example, referring to FIG. 7E, a control 506D for sharing the results of the evaluation to a website or friend may also be displayed in the area 506 of the user interface 50. In response to an operation (e.g., touch operation, click operation) received on control 506D, electronic device 200 can display a widget 506E as shown in fig. 7F in user interface 50. The widget 506E may include icons for one or more applications. The electronic device 200 may send the related information and the evaluation result of the multimedia file to a corresponding website server or a server of the instant messaging software in response to an operation (such as a touch operation or a click operation) detected on an icon of the application program, so as to share the evaluation result to a website or a friend.

By way of example, referring to fig. 7G, fig. 7G illustrates one possible user interface 51 displayed on a display screen after the electronic device 200 shares relevant information and evaluation results of a multimedia file to a website, which user interface 51 may be provided by a video-like application "hua video".

In an embodiment of the present application, a user interface implemented on an electronic device for displaying a result of evaluation may be referred to as a first user interface, such as the user interface 50 shown in fig. 7A-7D. The area of the first user interface for displaying the evaluation result may also be referred to as a first area, such as area 506 in user interface 50 shown in fig. 7A-7D.

The electronic device 200 may display the related information and the evaluation result of the multimedia file in other user interfaces without being limited thereto, instead of displaying the related information and the evaluation result of the multimedia file in the user interface 50 shown in fig. 7A to 7D.
