(1-3. System usage example)
Subsequently, a usage example of the display control system 1 according to the first embodiment of the present invention will be described. 3 to 6 are diagrams for explaining an example of use of the display control system 1 according to the first embodiment of the present invention. First, in the information presentation device 10, the acquisition unit 111 acquires information on each of the plurality of display areas from the server 40 via the communication unit 160. Then, the display control unit 119 controls so that the information of each of the plurality of display areas is displayed. The user can select any one of the plurality of display areas.

Referring to FIG. 3, a selection screen 181-1 for the user to select a region is displayed. On the selection screen 181-1, nine display areas are shown as an example of the plurality of display areas, and information is displayed in each of the nine display areas. However, the number of display areas is not limited as long as it is plural. The information displayed in each display area may include various contents such as image data and text data, but the type of information displayed in each display area is not limited.

The information displayed in each display area belongs to a certain category. Referring to FIG. 3, information (building A, building B, building C) is displayed as an example of information belonging to the category “building”. In addition, information (shader A, shrine B, shrine C) is displayed as an example of information belonging to the category "shader". Information (Garden A, Garden B, Garden C) is displayed as an example of information belonging to the category “Garden”. In this way, when the user's situation is not yet understood, it is desirable that the amount of information belonging to each category is displayed evenly among the categories, as shown in FIG.

An evaluation value is associated with each category. Initially, initial values are set to the evaluation values corresponding to each category. Here, it is assumed that zero is set as the initial value of the evaluation value. However, the initial evaluation value is not limited.

The display control unit 119 controls the information of each of the plurality of display areas based on the positive degree of the user when the user's gaze point exists in any of the plurality of display areas for a predetermined time or longer. This makes it possible to provide the user with the information that the user wants, without the user having to input the information necessary for the narrowing down. For example, the predetermined time may be 3 seconds or the like, but is not limited to a specific time. Hereinafter, control of information in each of the plurality of display areas will be described in more detail.

The gazing point specifying unit 112 specifies the gazing point of the user based on the sensor data of the eyeball of the user detected by the sensor unit 140. The gazing point may be specified in any way. For example, the gazing point specifying unit 112 may specify the gazing point of the user based on the imaging data obtained by sensing the user's eye movement detected by the sensor unit 140.

The positiveness calculation unit 113 is based on the sensor data of the user's face detected by the sensor unit 140 when the gazing point specified by the gazing point specifying unit 112 exists in any of the plurality of display areas for a predetermined time or longer. Then, the positive degree of the user is calculated. The positiveness may be calculated in any way. The positiveness calculation unit 113 adds a value according to the positiveness to the evaluation value corresponding to the category to which the information of the gazing area in which the gazing point exists for a predetermined time or longer among the plurality of display areas belongs. Here, the value according to the positiveness is not limited.

Here, when the positive degree of the user is equal to or higher than the predetermined positive degree, the positive degree calculating unit 113 adds 1 to the evaluation value corresponding to the category to which the information of the gaze area belongs, and the positive degree of the user is predetermined. Assume that the evaluation value is not added when it is less than the positive degree. However, the value added to the evaluation value may be a value other than 1. Alternatively, the positiveness calculation unit 113 may add the user's positiveness itself to the evaluation value.

Here, while the selection screen 181-1 (FIG. 3) is being displayed, the user looks at the display area in which “Architecture A” is displayed, and the positive degree of the user becomes equal to or higher than the predetermined positive degree, Assume that 1 is added to the evaluation value corresponding to "construction". Note that when the user's gazing point deviates from the gazing area, the calculation of the positive degree may be stopped (while maintaining the evaluation value).

The display control unit 119 controls the information of each of the plurality of display areas when there is one or a plurality of categories whose evaluation values have reached a predetermined value. Here, it is assumed that the predetermined value is 3. However, the predetermined value is not particularly limited.

Here, it is assumed that, while the selection screen 181-1 (FIG. 3) is being displayed, there is no one or more categories whose evaluation value has reached the predetermined value. However, while the selection screen 181-1 (FIG. 3) is being displayed, there may be one or more categories whose evaluation values have reached the predetermined value. In such a case, a process similar to the process executed when there is one or a plurality of categories whose evaluation values have reached a predetermined value on the selection screen 181-2 (FIG. 4) is executed as described below. May be done.

Note that there is a limit to the number of pieces of information that can be simultaneously displayed on the selection screen 181 (hereinafter, also referred to as “display category”). Therefore, first, the display section (first display section) displayed first is displayed in the plurality of display areas on the selection screen 181-1. Then, when the operation unit 130 detects a switching operation by the user (“swipe operation” in the example shown in FIG. 3), the display control unit 119 displays the information displayed in the plurality of display areas in the next display section. Switch to (second display category). The respective display categories may be acquired from the server 40 in a batch at first, or may be acquired from the server 40 every time a switching operation is detected.

Here, it is assumed that the user inputs a switching operation (for example, an upward swipe operation) on the selection screen 181-1 and the operation unit 130 detects the switching operation by the user. In such a case, the display control unit 119 switches the information displayed in the plurality of display areas to the next display section (switches from the first display section to the second display section). Referring to FIG. 4, there is shown a selection screen 181-2 in which the following display sections are displayed.

Referring to FIG. 4, information (building D, building E, building F) is displayed as an example of information belonging to the category “building”. Further, as an example of the information belonging to the category “shasha”, information (shaji D, shrine E, shrine F) is displayed. Information (Garden D, Garden E, Garden F) is displayed as an example of information belonging to the category “Garden”. As shown in FIGS. 3 and 4, it is desirable that the information displayed on the selection screen 181-1 and the information displayed on the selection screen 181-2 do not overlap.

Here, while the selection screen 181-2 (FIG. 4) is being displayed, the evaluation value has reached a predetermined value after the selection screen 181-1 (FIG. 3) is being displayed. Suppose there are multiple categories. In such a case, the display control unit 119 controls such that the information of each of the plurality of display areas is information that belongs to the same category corresponding to either one or a plurality of categories whose evaluation values have reached a predetermined value.

More specifically, while the selection screen 181-2 (FIG. 4) is being displayed, it is accumulated from the time the selection screen 181-1 (FIG. 3) is displayed and corresponds to the category “building”. It is assumed that the evaluation value is 4, the evaluation value corresponding to the category “garden” is 3, and the evaluation value corresponding to the category “shaji” is 1. That is, while the selection screen 181-2 (FIG. 4) is being displayed, the evaluation value and the category corresponding to the category “building” are accumulated since the selection screen 181-1 (FIG. 3) is displayed. Assume that each of the evaluation values corresponding to the "garden" has reached a predetermined value.

In such a case, the display control unit 119 displays information about the category “building” having the largest evaluation value among the categories whose evaluation value has reached the predetermined value (in the example shown in FIG. 4, “You are likely to be interested in building”. Message) is displayed. Further, in such a case, the display control unit 119 controls such that the information of each of the plurality of display areas is information that belongs to the category “architecture” having the largest evaluation value among the plurality of categories. If the user's attributes (for example, the user's age, sex, nationality, etc.) are analyzed from the sensor data and the like, the information about the category with the largest evaluation value is only for the user who is currently using the information presentation device 10. Instead, the cumulative evaluation value of the user group having the same attribute as the user may be replaced with information on the maximum category.

Here, the timing at which the information of each of the plurality of display areas is controlled to be the information that belongs to the same category “architecture” is not limited. For example, the display control unit 119 displays a message that information is updated after the category “building” in which the evaluation object has reached the predetermined value is detected, and automatically (or manually by pressing a button) You may control so that the information of each display area may belong to the same category "building."

Alternatively, when the switching operation of the information of each of the plurality of display areas is detected a predetermined number of times after the category in which the evaluation value reaches the predetermined value is detected, the display control unit 119 displays the information of each of the plurality of display areas. You may control so that it may become the information which belongs to the same category. More specifically, the narrowing-down validation unit 114 validates the narrowing-down trigger when a category in which the evaluator has reached a predetermined value is detected. Then, when the switching operation is detected a predetermined number of times after the narrowing-down trigger is activated, the information narrowing-down unit 115 narrows down the information in each of the plurality of display areas to the information belonging to the same category.

Here, it is assumed that the predetermined number of times is one. However, the predetermined number of times is not limited to a specific value. Alternatively, the predetermined number of times does not have to be a fixed value and may be changed according to the situation of the user. For example, the predetermined number of times may be changed according to the positiveness of the user. Specifically, it is assumed that the higher the degree of positiveness, the stronger the interest of the user in the information on the gaze area. Therefore, the higher the degree of positiveness, the less the predetermined number of times may be.

Here, on the selection screen 181-2, after the category “building” whose evaluation value has reached the predetermined value is detected, the user inputs the switching operation once, and the operation unit 130 detects the switching operation once by the user. Suppose that it has been done. In such a case, the display control unit 119 controls such that the information of each of the plurality of display areas is information that belongs to the same category “architecture”. Referring to FIG. 5, there is shown a selection screen 181-3 in which information belonging to the same category “architecture” is displayed in each of a plurality of display areas.

With reference to FIG. 5, information (buildings A to I) is displayed on the selection screen 181-3 as an example of information belonging to the same category “building”. In addition, referring to FIG. 5, on the selection screen 181-3, information displayed before the switching (for example, the buildings A to C of the selection screen 181-1 (FIG. 3), the selection screen 181-2 (FIG. 4). ) Buildings D to F) are also displayed. However, the information displayed before the switching may not be displayed on the selection screen 181-3.

Here, it is assumed that the user inputs a switching operation (for example, an upward swipe operation) on the selection screen 181-3 and the operation unit 130 detects the switching operation by the user. In such a case, the display control unit 119 switches the information displayed in the plurality of display areas to the next display section. Referring to FIG. 6, there is shown a selection screen 181-4 in which the following display sections are displayed.

Referring to FIG. 6, information (buildings J to R) is displayed on the selection screen 181-4 as an example of information belonging to the same category “building”. Further, when the switching operation by the user is detected, the next display section may be similarly displayed.

In the example shown in FIG. 4, it is mainly assumed that there are two categories in which the evaluation value reaches the predetermined value. However, it is assumed that there is one category whose evaluation value has reached the predetermined value. In such a case, the display control unit 119 may control the information of each of the plurality of display areas to be information that belongs to a category whose evaluation value has reached a predetermined value. In such a case, the display control unit 119 may perform control so that information regarding a category whose evaluation value has reached a predetermined value (a message such as "You are likely to be interested in architecture.") is displayed.

When one of the plurality of display areas is selected and the user inputs a confirming operation, the ticket issuing unit 190 issues a ticket corresponding to the information displayed in the selected display area. For example, when the user inputs a confirmation operation, the ticket issuing unit 190 issues a ticket by printing the content corresponding to the information displayed in the selected display area on the paper.

(1-4. System operation example)
Subsequently, an operation example of the display control system 1 according to the first embodiment of the present invention will be described. FIG. 7 is a flowchart showing an operation example of the display control system 1 according to the first embodiment of the present invention. As shown in FIG. 7, in the information presentation device 10, the acquisition unit 111 acquires information on each of the plurality of display areas from the server 40 via the communication unit 160. Then, the display control unit 119 controls so that the information of each of the plurality of display areas is displayed. At this time, it is desirable that the display control unit 119 perform display control so that the number of cases displayed in each category is even among the categories (S11).

Subsequently, the sensor unit 140 acquires the sensor data of the eyeball of the user and the sensor data of the face of the user (S12). The gazing point specifying unit 112 specifies the gazing point of the user based on the sensor data of the eyeball of the user detected by the sensor unit 140. The positiveness calculation unit 113 determines, based on the gazing point specified by the gazing point specifying unit 112, whether or not the user has gazed at one area of the plurality of display areas for a predetermined time or more (S16). When it is determined that the user is not gazing at one area of the plurality of display areas for a predetermined time or longer (“NO” in S16), the operation is shifted to S14.

When the operation is moved to S14, if there is no operation (switching operation) for displaying the next display section (“NO” in S14), the operation is moved to S12. On the other hand, if there is an operation (switching operation) for displaying the next display section (“YES” in S14), the display control unit 119 controls so that the next display section is displayed (S15), and S12. The operation is transferred to.

On the other hand, the positiveness calculation unit 113, when it is determined that the user is gazing at one area of the plurality of display areas for a predetermined time or more (“YES” in S16), the sensor of the user's face detected by the sensor unit 140. The positive degree of the user is calculated based on the data. Then, the positiveness degree calculation unit 113 adds a value according to the positiveness degree to the evaluation value corresponding to the category to which the information of the gaze area belongs (S17).

When the evaluation body corresponding to the category to which the information of the gaze area belongs has not reached the predetermined value (“NO” in S18), the operation proceeds to S12. On the other hand, when the evaluation object corresponding to the category to which the information on the gaze area belongs is equal to or larger than the predetermined value (“YES” in S18), the narrowing-down validation unit 114 determines that the narrowing-down (narrowing-down trigger) is invalid (in S19). "YES"), narrowing down (thinning trigger) is enabled (S20), and the operation moves to S21. If the narrowing down (thinning trigger) is valid (“NO” in S19), the operation proceeds to S21.

If the user has not performed the display segment transition operation a predetermined number of times after the narrowing-down trigger is activated (“NO” in S21), the operation proceeds to S12.
