Description

The present invention relates to a program, a server, and a presentation method.

Conventionally, when viewing of a video presented on a screen is stopped and then resumed, a technique is known in which the presentation of the video is started from the point where viewing was stopped. For example, Patent Document 1 discloses a technique in which, on a screen including video thumbnails, when viewing of the video thumbnails is stopped due to the start of scrolling, playback of the video thumbnails is paused, the video thumbnails remain on the screen after scrolling ends, and when viewing is resumed, playback of the video thumbnails continues from where it was paused.

Patent No. 4536146

In the above-mentioned technologies, the content of the video is fixed and does not change between the time viewing is stopped and the time viewing is resumed. On the other hand, the state of the object presented as video may change over time, and the state of the object may change over time after viewing is stopped. For such objects whose state changes over time, when viewing is resumed after viewing is stopped, there is a demand to be able to view the changes over time from the time viewing was stopped to the time viewing is resumed.

(3. Functional configuration of presentation device according to embodiment)
The functional configuration of the presentation device 100 will be described with reference to FIG.

The presentation device 100 functionally comprises a detection unit 101, an acquisition unit 102, a request transmission unit 103, a response reception unit 104, a display unit 105, and a recording unit 106. In this embodiment, the CPU 11 functions as the detection unit 101, the acquisition unit 102, and the recording unit 106, the CPU 11 and the communication device 16 cooperate to function as the request transmission unit 103 and the response reception unit 104, and the CPU 11 and the output device 15 cooperate to function as the display unit 105.

Below, the functions of the presentation device 100 according to this embodiment will be described with respect to a sports promotion lottery match. A sports promotion lottery is a lottery in which a user predicts and votes for the outcome or score of a sports match, and if the prediction is correct, the user can receive a prize. An application for voting in the sports promotion lottery is installed in the presentation device 100, and the functions of each part are realized on the application. Users use this application to view information about the match and to cast their votes. Users also use the application repeatedly before voting begins, during the match, and even after the voting results are made public at the end of the match.

Figure 4 shows an example of page 400-1 displayed in an application for voting in a sports promotion lottery (hereinafter simply referred to as the "application"). Page 400-1 includes an area 401 in which the name of the game and information on the opposing teams are displayed, an area 402 in which an animation of the stadium is displayed, and an area 403 in which detailed information on the game and the sports promotion lottery is displayed. Area 402 displays an image 404 of the stadium's field, an image 405 of the stadium's stands, an image 406 of the sky above the stadium, and images 407 and 408 of the opposing team names. Images 404 to 406 change over time while the user is using the application, thereby displaying an animation of the stadium. The animation display is performed so that the change in the state of the target over time can be recognized, as described below. In addition to page 400-1, the application displays a page for voting, a list of games in the sports promotion lottery, and the like.

The presentation device 100 records the object whose status has been viewed by the viewer in association with the last date and time of the most recent state displayed on the screen among the viewed objects.

A viewer is someone who views the state of an object, for example, a user of an application.

The state of an object changes over time. For example, the state of an object, that is, the state of a match, is the state of the sports promotion lottery votes, the odds of the sports promotion lottery, the sky above the stadium where the match is played, and the status of the match. Generally, the sports promotion lottery allows voting from a few days (e.g., one week) until several tens of minutes (e.g., 10 minutes) before the start date and time of the match, and the state of the votes and odds changes over time until voting closes. In addition, the state of the sky above the stadium changes over time in terms of brightness and weather. In addition, the state of the match status changes over time, from before the match starts, during the match, to after the match ends, and further, when the match is in progress, information such as the score and penalty changes.

In the application, images 404-406 included in area 402 change and are displayed in a fast-forward animation so that the user can recognize the change in the state of the match over time while using the application. Here, information about the state of the sports promotion lottery votes, the sports promotion lottery odds, the sky above the stadium where the match is being held, and the state of the match (hereinafter referred to as "state information") is managed by server 200 as time-series data in association with the date and time.

Figure 5 shows an example of status information managed by server 200. The status information includes a match ID for identifying the sports promotion lottery match, the date and time of the match status, the number of votes, odds, the weather above the stadium where the match is held, and the event status, all of which are associated with each other. In the following, the status information is recorded with each value recorded every five minutes from three days before the start of voting for the sports promotion lottery until the lottery results are announced.

The information on the first line of Figure 5 indicates that for the match with match ID "XXX-1", the number of votes for Team AAA as of "11:00 AM on March 17, 2022" is "0", the odds for Team AAA are "0.0", the weather is "cloudy", and the event status is "before voting begins". Note that the match with match ID "XXX-1" is a match between Team AAA and Team BBB.

As described below, in response to a request from the presentation device 100, the server 200 transmits status information from the last date and time specified in the request to the current date and time to the presentation device 100. The presentation device 100 performs animation display by changing the image in the area 402 based on the status information provided by the server 200. Therefore, by looking at the animated image in the area 402, the user can recognize the changes over time in the votes for the sports promotion lottery, the odds for the sports promotion lottery, the sky above the stadium where the game is being played, and the status of the game being held.

The final date and time is the date and time of the state of the object that has been viewed by the viewer and was most recently displayed on the screen, and is the date and time of the state of the object when the viewer last viewed it. The final date and time is, for example, the date and time of the state information based on the image that was most recently displayed on the screen among images displayed as animations. The final date and time continues to be updated if the viewing continues. In other words, the final date and time recorded in the presentation device 100 is updated to approach the current date and time during viewing.

Figure 6 shows an example of viewing information including final information recorded by the presentation device 100. The viewing information includes a match ID and a final date and time in association with each other. The viewing information is stored in the recording medium 14. The final date and time of the viewing information is updated each time the image displayed on the screen while the user is viewing is updated.

The information on the first line in FIG. 6 indicates that the user has viewed the status of the match with the target ID "XXX-1" as of "11:30 AM, March 22, 2022." Additionally, the information on the second line in FIG. 6 indicates that the user has not yet viewed the match with the target ID "XXX-2."

The detection unit 101 in FIG. 3 detects whether the viewer is viewing the target state.

Specifically, the detection unit 101 detects whether the viewer has started viewing the target state, is viewing, has stopped viewing, or is not viewing. For example, the detection unit 101 detects that the user has started viewing the target state when the application area 402 is displayed on the screen of the presentation device 100. Furthermore, the detection unit 101 detects that the user is viewing the target state when the application area 402 is continuously displayed on the screen of the presentation device 100. Furthermore, the detection unit 101 detects that the user has stopped viewing the target state when the application area 402 is no longer displayed on the screen of the presentation device 100. Furthermore, the detection unit 101 detects that the user is not viewing the target state when the application area 402 is no longer continuously displayed on the screen of the presentation device 100.

For example, when a user displays page 400-1 (Figure 4) of a match with target ID "XXX-1" in an application and area 402 appears on the screen, detection unit 101 detects that the user has started viewing the status of the match with target ID "XXX-1". Then, when area 402 continues to be displayed on the screen, detection unit 101 detects that the user is viewing the status of the match with target ID "XXX-1".

When the acquisition unit 102 detects that viewing has started, it acquires the final date and time for the object for which viewing has started.

For example, when the detection unit 101 detects that a user has started viewing the status of the match with the target ID "XXX-1", the acquisition unit 102 refers to the viewing information in FIG. 6 and acquires the final date and time of the match with the target ID "XXX-1", "11:30 AM, March 22, 2022".

The request sending unit 103 sends a request to the server 200, specifying the last date and time acquired for the object for which viewing has started.

The request is to ask the server 200 to provide the time-change information described below.

For example, the request sending unit 103 sends a request to the server 200, specifying the target ID "XXX-1" and the final date and time "March 22, 2022, 11:30."

The response receiving unit 104 receives a response from the server 200 that specifies information about changes over time for the object that was started to be viewed from the last date and time to the current date and time.

The current date and time is the current date and time when the viewer is viewing the target state. In the following, the date and time when the server 200 receives the request is considered to be the current date and time.

Change-over information is information that indicates the change in the state of the target over time, and is status information from the specified last date and time to the current date and time. For example, if the current date and time is "March 24, 2022, 17:00", the change-over information includes status information for every 5 minutes from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00".

For example, the response receiving unit 104 receives from the server 200 time-dependent change information that includes status information for every 5 minutes from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00".

While the viewer is viewing the content, the display unit 105 displays on the screen of the presentation device 100 the state of the object that has started to be viewed in chronological order from the last date and time to the current date and time, based on the time-dependent change information specified in the received response.

For example, if a user keeps area 402 displayed on the screen for a predetermined period of time, the detection unit 101 detects that the user is viewing the area, and the display unit 105 changes the image displayed in area 402 and displays an animation based on the values for each 5 minutes from the last date and time "11:30, March 22, 2022" to the current date and time "17:00, March 24, 2022".

Specifically, the display unit 105 displays the image 406 so that the brightness of the sky changes based on the date and time of the status information. For example, when the date and time of the status information indicates daytime, the display unit 105 adjusts the RGB values to express the brightness of daytime, and when the date and time of the status information indicates nighttime, the display unit 105 adjusts the RGB values to express the darkness of night.

The display unit 105 also displays the weather in the sky shown in the image 406 so that it changes based on the weather in the status information. For example, if the weather in the status information is cloudy or rainy, the display unit 105 adjusts the transparency to represent cloudy or rainy conditions.

Furthermore, the display unit 105 places dots in the team colors of each team in the stands shown in the image 405 based on the number of votes in the status information, and displays the number of dots placed changing. For example, the display unit 105 expresses the number of votes cast for each team by placing dots in the team colors of team AAA in a number corresponding to the number of votes for team AAA among the number of votes in the status information, and placing dots in the team colors of team BBB in a number corresponding to the number of votes for team BBB.

The display unit 105 also changes the base color of the stands shown in the image 405 to the team color of the team with the higher value based on the odds of the status information. For example, if the odds of the status information are higher for team BBB than for team AAA, the display unit 105 expresses the odds by adjusting the RGB values to change the base color of the stands to the team color of team BBB.

The display unit 105 also changes between color and monochrome display based on the event status of the status information. For example, when the event status of the status information is from the start of voting until the end of the match, the display unit 105 expresses the event status by adjusting the saturation to display in color, and when the event status of the status information is after the match ends, the display unit 105 expresses the event status by adjusting the saturation to display in monochrome. In this way, a sense of activity is expressed by the color display from the start of voting until the end of the match, and a sense of inactivity is expressed by the monochrome display after the match ends. Also, for example, when the event status of the status information is during the match, the display unit 105 displays score information.

Figure 7 shows the image of area 402 displayed based on the status information of "March 22, 2022, 11:30" (Figure 5), Figure 8 shows the image of area 402 displayed based on the status information of "March 23, 2022, 23:00" (Figure 5), and Figure 9 shows the image of area 402 displayed based on the status information of "March 24, 2022, 17:00" (Figure 5). In Figures 7 to 9, the dot type of dot 409 indicates team AAA, and the dot type of dot 410 indicates team BBB. Note that Figures 7 to 9 omit the changes based on the odds of the status information. The display unit 105 displays the images shown in Figures 7 to 9 in chronological order from the last date and time to the current date and time, thereby displaying an animation.

For example, when the detection unit 101 detects that the user has started viewing the status of the match of the target ID "XXX-2", the acquisition unit 102 refers to the viewing information in FIG. 6 and acquires the last date and time "none". Then, the request transmission unit 103 transmits a request in which the target ID "XXX-2" and the last date and time "none" are specified. In this case, when the server 200 receives the request in which the target ID "XXX-2" and the last date and time "none" are specified, the server 200 refers to the status information and transmits a response to the presentation device 100 in which the information on the change over time from the last date and time to the current date and time is specified, with the last date and time being the oldest date and time among the dates and times of the target ID "XXX-2", that is, the first date and time when the recording of the status information started. The response reception unit 104 receives the response in which the information on the change over time from the oldest date and time to the current date and time for the target ID "XXX-2" is specified, and the display unit 105 displays an animation based on the information on the change over time from the oldest date and time to the current date and time.

The display unit 105 also displays the state of the target for which viewing has begun, within a first predetermined time period, based on the time-varying information. The first predetermined time period varies depending on the period from the last date and time to the current date and time.

For example, if the period from the last date and time to the current date and time is less than three days, the first predetermined time is 15 seconds, if the period from the last date and time to the current date and time is three or more days but less than seven days, the first predetermined time is 30 seconds, and if the period from the last date and time to the current date and time is seven days or more, the first predetermined time is 45 seconds.

For example, the display unit 105 displays an animation for 15 seconds based on the values every 5 minutes from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00".

In addition, if the change in the state of the object to be displayed based on the time-change information does not satisfy a predetermined condition at the first specified time, the display unit 105 does not display the state of the object that has started to be viewed based on the time-change information.

The predetermined condition is a condition regarding the degree of change. For example, the predetermined condition is a threshold for the difference between the values of the first date and time and the last date and time of the status information included in the time-change information, and the threshold is a value at which the degree of change is deemed small. The threshold is set arbitrarily by the administrator of the server 200. The predetermined condition is set for at least one of the date and time of the status information, the number of votes, the odds, the weather, and the event status.

For example, if the difference between the first date and time and the last date and time of the status information included in the time-change information is less than one hour, when the status of the target is displayed in chronological order over 15 seconds based on the time-change information, the changes are small and displayed slowly, and the user may not notice the change in status. Therefore, in such a case, it is deemed that the change in the status of the target displayed based on the time-change information does not satisfy the predetermined condition, and the display unit 105 does not display the status of the target whose viewing has started based on the time-change information.

For example, the server 200 refers to the status information from the last date and time specified in the request sent from the request sending unit 103 to the current date and time and judges whether the status information included in the time-based change information satisfies a predetermined condition. When the server 200 judges that the status information included in the time-based change information satisfies the predetermined condition, it sends a response in which the time-based change information is specified to the presentation device 100. On the other hand, when the server 200 judges that the status information included in the time-based change information does not satisfy the predetermined condition, it sends a response including a notice to the presentation device 100 that there is no time-based change information. When the response receiving unit 104 receives a response including a notice to the effect that there is no time-based change information, the display unit 105 does not animate the status of the match for which viewing has started based on the time-based change information, but, for example, displays a fixed area 402 that is displayed when viewing has started.

The recording unit 106 records the date and time of the state most recently displayed on the screen as the final date and time each time the state of the target that was started to be viewed in chronological order is displayed.

For example, when the display unit 105 displays the area 402 based on the status information of "March 23, 2022, 23:00", as shown in FIG. 8, the recording unit 106 updates the last date and time associated with the target ID "XXX-1" in the browsing information of FIG. 6 to "March 23, 2022, 23:00" and records it. Also, when the display unit 105 displays the area 402 based on the status information of "March 23, 2022, 23:05", the recording unit 106 updates the last date and time associated with the target ID "XXX-1" in the browsing information of FIG. 6 to "March 23, 2022, 23:05" and records it. The recording unit 106 updates the last date and time of the browsing information of FIG. 6 until the browsing is stopped.

The detection unit 101 also causes the presentation device 100 to retain the time-change information specified in the received response for a second predetermined time period after the viewing of the state of the target that was started to be viewed is stopped.

The second specified time is a value set arbitrarily by the application administrator, for example, 5 minutes.

For example, the detection unit 101 stores the time-change information specified in the response received by the response receiving unit 104 in the recording medium 14 for five minutes after it is detected that browsing has stopped.

The request sending unit 103 refrains from sending a request for a second predetermined time after viewing of the target state that was started to be viewed is stopped.

For example, for five minutes after the detection unit 101 detects that browsing has stopped, the request sending unit 103 does not send a request for the provision of time-change information, even if the detection unit 101 detects that browsing has started, i.e., that browsing has been resumed.

When viewing of the state of the target that was started is stopped and viewing is resumed within a second predetermined time, the display unit 105 resumes displaying the state of the target from the point at which viewing was stopped, based on the retained time-change information.

For example, suppose that while the display unit 105 is displaying an animation based on time-based change information including status information from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00", and area 402 is displayed on the screen based on status information for "March 23, 2022, 23:00", the detection unit 101 detects that viewing has been stopped. In this case, the recording unit 106 records the last date and time as "March 23, 2022, 23:00". Then, for up to five minutes after the detection of the viewing stop, the detection unit 101 causes the recording medium 14 to retain the time-based change information including status information from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00". Then, when the detection unit 101 detects the start (resumption) of viewing at "March 24, 2022, 17:01", the request sending unit 103 does not send a request, and the display unit 105 displays an animation based on the updated status information from the last date and time "March 23, 2022, 23:00" to the current date and time "March 24, 2022, 17:00" based on the time-change information including the status information from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00" stored in the recording medium 14.

On the other hand, when viewing of the target state that was started by the detection unit 101 is resumed at "17:06, Mar. 24, 2022", five minutes after the viewing is stopped, the request sending unit 103 sends a request specifying the final date and time "23:00, Mar. 23, 2022". Next, the response receiving unit 104 receives from the server 200 a response specifying time-dependent change information including status information for every five minutes from the final date and time "23:00, Mar. 23, 2022" to the current date and time "17:06, Mar. 24, 2022". The display unit 105 then performs animation display based on the time-dependent change information specified in the received response.

(4. Functional configuration of the server according to the embodiment)
The functional configuration of the server 200 will be described with reference to FIG.

The server 200 functionally comprises a request receiving unit 201 and a response sending unit 202. In this embodiment, the CPU 11 and the communication device 16 work together to function as the request receiving unit 201 and the response sending unit 202.

The request receiving unit 201 receives a request from the presentation device 100 that specifies the last date and time that was obtained for the object that the viewer started viewing.

For example, the request receiving unit 201 receives a request from the presentation device 100 that specifies the target ID "XXX-1" indicating the match that the user started viewing and the final date and time "March 22, 2022, 11:30."

The response sending unit 202 sends a response to the presentation device 100, in which information on changes over time of the object that has been started to be viewed from the last date and time to the current date and time is specified.

For example, the response sending unit 202 refers to the status information in FIG. 5 to identify status information for every 5 minutes from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00", and sends a response in which time-dependent change information including the identified status information is specified to the presentation device 100.

Then, while the viewer is viewing the content, the presentation device 100 displays on the screen the state of the object that has started to be viewed in chronological order from the last date and time to the current date and time, based on the time-dependent change information specified in the response sent from the server 200.

For example, in the presentation device 100, when the response receiving unit 104 receives a response in which time-change information is specified and the detection unit 101 detects that the user is viewing the image, the display unit 105 changes and animates the image displayed in the area 402 based on the values for each 5 minutes from the last date and time "11:30, March 22, 2022" to the current date and time "17:00, March 24, 2022" contained in the time-change information.

(5. Operation of Presentation Device of the Embodiment)
The presentation process executed by the presentation device 100 of the present embodiment will be described with reference to Fig. 10. For example, when a user starts an application, the presentation process of Fig. 10 starts.

The detection unit 101 detects whether the viewer has started viewing the target state (step S101). When the detection unit 101 detects that the viewer has started viewing the target state (step S101; YES), the acquisition unit 102 acquires the final date and time for the target whose viewing has started (step S102). On the other hand, when the detection unit 101 does not detect that the viewer has started viewing the target state (step S101; NO), it waits as it is.

For example, when a user displays page 400-1 (Figure 4) of a match with target ID "XXX-1" in an application and area 402 is displayed on the screen, detection unit 101 detects that the user has started viewing the status of the match with target ID "XXX-1". Then, acquisition unit 102 refers to the viewing information in Figure 6 and acquires the final date and time of the match with target ID "XXX-1", "11:30 on March 22, 2022". On the other hand, if area 402 is not displayed on the screen, detection unit 101 does not detect that the user has started viewing the status of the match and continues to wait.

The request sending unit 103 sends a request to the server 200, specifying the last date and time acquired for the object for which viewing has started (step S103).

For example, the request sending unit 103 sends a request specifying the target ID "XXX-1" and the final date and time "March 22, 2022, 11:30."

The response receiving unit 104 receives a response from the server 200 specifying information about changes over time of the object that was started to be viewed from the last date and time to the current date and time (step S104).

For example, the response receiving unit 104 receives from the server 200 time-dependent change information that includes status information for every 5 minutes from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00".

The display unit 105 starts displaying the state of the object for which viewing has started in chronological order from the last date and time to the current date and time based on the time-change information specified in the received response (step S105).

For example, the display unit 105 starts displaying an animation based on the status information every 5 minutes from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00".

The recording unit 106 records, in chronological order, the date and time of the state most recently displayed on the screen as the final date and time each time the state of the target whose viewing has started is displayed (step S106).

For example, when the display unit 105 displays the area 402 based on the status information of "March 23, 2022, 23:00 p.m.," as shown in FIG. 8, the recording unit 106 records the last date and time associated with the target ID "XXX-1" in the viewing information of FIG. 6 as "March 23, 2022, 23:00 p.m.."

The display unit 105 determines whether or not a first predetermined time has elapsed since the start of display (step S107). If the display unit 105 determines that the first predetermined time has elapsed since the start of display (step S107; YES), it ends the display (step S108) and proceeds to step S111. On the other hand, if the display unit 105 determines that the first predetermined time has not elapsed since the start of display (step S107; NO), the detection unit 101 determines whether or not viewing has been stopped (step S109).

For example, if the display unit 105 determines that the first predetermined time "15 seconds" has elapsed since the start of the animation display, it ends the animation display and proceeds to step S111. On the other hand, if the display unit 105 determines that the first predetermined time "15 seconds" has not elapsed since the start of the animation display, the detection unit 101 determines whether or not it has detected that viewing has stopped.

When the detection unit 101 determines that the viewing has been stopped (step S109; YES), the display unit 105 stops the display, and the detection unit 101 causes the presentation device 100 to store the time-change information (step S110). On the other hand, when the detection unit 101 determines that the viewing has not been stopped (step S109; NO), the process returns to step S106.

For example, if the detection unit 101 determines that viewing has been stopped when an image is displayed in the area 402 based on the status information of "March 23, 2022, 23:00", the display unit 105 stops the display, and the detection unit 101 stores, in the recording medium 14, time-change information including status information from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00".

The detection unit 101 judges whether or not a second predetermined time has elapsed since the viewing of the state of the target whose viewing was started was stopped (step S111). When the detection unit 101 judges that the second predetermined time has elapsed since the viewing of the state of the target whose viewing was started was stopped (step S111; YES), the process returns to step S101. On the other hand, when the detection unit 101 judges that the second predetermined time has not elapsed since the viewing of the state of the target whose viewing was started was stopped (step S111; NO), the detection unit 101 detects whether or not the viewing has been resumed (step S112). Then, when the detection unit 101 detects that the viewing has been resumed (step S112; YES), the display unit 105 resumes the display of the state of the target from the point when the viewing was stopped based on the retained time-change information (step S113). Then, the process proceeds to step S106. On the other hand, when the detection unit 101 does not detect that the viewing has been resumed (step S112; NO), the process proceeds to step S111.

For example, if the detection unit 101 determines that five minutes have passed since it detected the suspension of browsing, it returns to step S101. On the other hand, if the detection unit 101 determines that five minutes have not passed since it detected the suspension of browsing, it detects whether browsing has been resumed. If the detection unit 101 detects resumption within five minutes of the suspension of browsing, the display unit 105 starts animation display based on the updated status information from the last date and time "March 23, 2022, 23:00" to the current date and time "March 24, 2022, 17:00" based on the time-varying information including the status information from the last date and time "March 22, 2022, 11:30" to the current date and time "March 24, 2022, 17:00" stored in the recording medium 14. On the other hand, if the detection unit 101 does not detect resumption within five minutes of the suspension of browsing, it returns to step S111.

According to this embodiment, among the changes over time in the state of the object, those changes over time that the viewer has not viewed can be presented to the viewer. Therefore, when the user resumes viewing the state of the object, the changes in the state of the object that occurred between the time viewing was stopped and the time viewing was resumed can be visually and intuitively grasped.

Furthermore, according to this embodiment, the state of the target is displayed within a predetermined time based on information on changes over time from the last date and time to the current date and time, and the predetermined time is adjusted based on the period from the last date and time to the current date and time. As a result, if the period for displaying changes in the target's state is long, the displayed period is extended, allowing the user to check the changes over time in the target's state at an appropriate speed.

In addition, according to this embodiment, if the change over time of the target state does not satisfy a predetermined condition, no display based on the change over time information is performed. As a result, if the change over time is difficult for the user to recognize, the animation display process can be omitted, and the processing load of the presentation device can be reduced.

In addition, according to this embodiment, if viewing is resumed in a short period of time after being stopped, the transmission of a request for the provision of time-change information is suppressed, and display is started from the point where it was stopped based on the retained time-change information. This can reduce the processing related to communication between the presentation device and the server.

(6. Modifications)
Although the embodiment of the present invention has been described above, various modifications and applications are possible in carrying out the present invention.

In the above embodiment, an example was shown in which one page contains information about one object (match) and presents the change in the state of one object over time, but this is not limiting, and the presentation device 100 can also present the change in the state of multiple objects over time.

Specifically, a single page displayed on the screen has multiple objects arranged so that they can be displayed by scrolling, and the detection unit 101 may detect that viewing has started when the objects are displayed on the screen by scrolling to a first predetermined percentage or more of the objects, and detect that viewing has stopped when the objects are no longer displayed on the screen by scrolling to a second predetermined percentage or more of the objects.

Figure 11 shows an example of a page on which multiple objects are arranged so that they can be displayed by scrolling. Page 400-2 is a list page of sports promotion lottery matches. Page 400-2 includes areas 411-413 in which animations are displayed for each of the multiple matches. When areas 411-413 are selected by tapping or the like, the page transitions to a page showing detailed information about each match as shown in page 400-1. Areas 411-413 include an image of the field, an image of the stands of the stadium, and an image of the sky above the stadium, similar to area 402 of page 400-1. Areas 411-413 also include images 414, 417, and 420 of the names of the respective matches, and images 415, 416, 418, 419, 421, and 422 of the names of the opposing teams. In Figure 11, rectangle 423 indicates the area displayed on the screen of presentation device 100. Scrolling moves the position of rectangle 423 up and down, and therefore changes the game information displayed on the screen.

For example, when the area of the match on the screen (rectangle 423) is displayed at or above a first predetermined percentage of the screen, the detection unit 101 detects that viewing of the match in that area has started. Also, when the area of the match on the screen (rectangle 423) is no longer displayed at or above a second predetermined percentage of the screen, the detection unit 101 detects that viewing of the match in that area has stopped. For example, the first predetermined percentage is 70% and the second predetermined percentage is 30%. For example, as shown in FIG. 12, when the screen (rectangle 423) is scrolled downward and 70% or more of area 412 is displayed, the detection unit 101 detects that viewing of the state of the match displayed in area 412 has started. Also, as shown in FIG. 12, when the screen (rectangle 423) is scrolled downward and 30% or more of area 411 is no longer displayed, the detection unit 101 detects that viewing of the state of the match displayed in area 411 has stopped.

When the detection unit 101 detects that viewing of the game status displayed in area 412 has started, the acquisition unit 102 acquires the final date and time for the game displayed in area 412, the request sending unit 103 sends a request specifying the final date and time to the server 200, and the response receiving unit 104 receives a response from the server 200 specifying information on changes over time of the game displayed in area 412 from the final date and time to the current date and time. The display unit 105 then displays an animation based on the information on changes over time for the game status displayed in area 412. On the other hand, when the detection unit 101 detects that viewing of the game status displayed in area 411 has been stopped, the display unit 105 stops displaying the animation based on the information on changes over time for the game status displayed in area 411.

Furthermore, when area 411 is displayed to occupy more than a first predetermined percentage of the screen within a second predetermined time by scrolling, request sending unit 103 does not send a request to server 200, and display unit 105 starts displaying from the point where viewing was stopped, based on the retained time-change information. On the other hand, when area 411 is displayed to occupy more than a first predetermined percentage of the screen by crawling after the second predetermined time has elapsed, request sending unit 103 sends a request to server 200, and starts displaying an animation of the state of the match, based on the specified time-change information specified in the response received from server 200.

In the above embodiment, the weather information is displayed in chronological order based on the weather, but this is not limited to the above. For example, if the time-varying information includes multiple days of status information, the weather changes for the same time period may be displayed in one day. For example, the time-varying information may include only the most common or least common representative weather status information among the weather for the same time period on multiple days. For example, if the time-varying information includes three days of status information, and the weather from 12:00 to 15:00 is sunny, rainy, and sunny, the weather from 12:00 to 15:00 included in the time-varying information is set to sunny. The number of days to be combined may be adjusted according to the number of days of status information included in the time-varying information. For example, if the time-varying information includes six days of status information, the weather changes for six days may be displayed in two days. If the changes in the sky over six days are displayed as they are, morning and night are repeated six times within the first predetermined time period, and the playback speed is displayed quickly, which may make it difficult to grasp the status. However, by displaying the representative weather as changes over several days in this way, it becomes easier to grasp the status.

In addition, by applying a program that specifies the operation of the presentation device 100 according to the above embodiment to an existing personal computer or information terminal device, it is possible to cause the personal computer or information terminal device to function as the presentation device 100 according to the embodiment.

The present invention allows for various embodiments and modifications without departing from the broad spirit and scope of the present invention.
