The direction information acquisition unit 142 obtains from the data processing device 2 direction information indicating that the “face” is facing “downward”, the “right hand” is facing “lower middle”, and the “left hand” is facing “upper lower”. get.

The display control unit 143 causes the display unit 12 to display both the acquired front moving image and the direction information. FIG. 3 is a diagram showing an example of a screen displayed on the information terminal 1. As shown in FIG. On the screen shown in FIG. 3, the display control unit 143 displays the acquired front moving image at the display position O1 in the center of the screen. Then, the display control unit 143 displays the acquired direction information at a position O2 outside the display position O1 of the front moving image on the screen.

Note that the display positions of the acquired moving image and the direction information are arbitrary. For example, the display control unit 143 may arrange the acquired moving image on the left side of the screen and arrange the direction information on the right side of the moving image for display.

The direction information may be set for each predetermined frame interval among the frames forming the moving image. In this case, the direction information acquisition unit 142 acquires the direction information set for each predetermined frame interval, and the display control unit 143, when displaying a frame in which the direction information is not set, displays the frame before the frame to be displayed. Direction information associated with the time closest to the frame to be displayed is displayed.

Moreover, the direction information acquisition unit 142 may further acquire information indicating the display position set for each part of the body. In the example of FIG. 3, the display position of the "face" is displayed in the "upper left part of the screen", the display position of the "right hand" is displayed in the "middle left part of the screen", and the display position of the "left hand" is displayed in the "lower right part of the screen". Get location information that indicates Then, the display control unit 143 displays direction information based on the display position information acquired by the direction information acquisition unit 142 .

The display control unit 143 may superimpose the direction information on the acquired moving image for display. In this case, the direction information acquisition unit 142 acquires the display position information of the direction information in the form of coordinates indicating the position in the moving image frame. Then, the display control unit 143 displays the moving image on which the direction information is superimposed at the position specified by the display position information.

By configuring the information terminal 1 in this manner, the information terminal 1 can display information that enables the user to understand the direction in which the body should be moved, together with the moving image.

Here, the user may want to select and view the video of the performer's performance and the video of the performer's dance that is left-right reversed according to the situation. Therefore, the information terminal 1 may be configured to be able to select a display mode in which the acquired moving image is displayed as it is, or a display mode in which the acquired moving image is displayed in reverse.

The selection unit 144 accepts selection of a display mode between normal display in which the obtained moving image is displayed without being reversed and reverse display in which the obtained moving image is horizontally reversed and displayed. On the display screen shown in FIG. 3, an icon O3 is arranged for the user to switch the display mode. When the user performs an operation (for example, clicking or tapping) to press the icon O3, information indicating the selected display mode is transmitted to the data processing device 2 . In the example of the screen in FIG. 3, since the icon O3 is pressed when the normal display is selected, information indicating that the reverse display is selected is transmitted. The display control unit 143 may be configured to further display a screen for selecting a display mode when the icon O3 is pressed.

When the reverse display is selected, the display control unit 143 causes the display unit 12 to display the obtained front moving image in a horizontally reversed manner. FIG. 4 is a diagram showing an example of a screen displayed on the information terminal 1. As shown in FIG. FIG. 4 shows a screen displayed when the selection unit 144 selects the display mode of reverse display. When the display mode accepted by the selection unit 144 is reversed display, the display control unit 143 performs a process of horizontally reversing the acquired moving image, and causes the display unit 12 to display the reversed moving image.

Here, since the user who sees the reversed display image can move according to the image, the user can understand the movement without displaying the direction information. That is, on the screen shown in FIG. 4, the display control unit 143 does not display the direction information.

When the normal display is selected, the display control unit 143 causes the display unit 12 to display both the obtained front moving image and the direction information. That is, when the display mode accepted by the selection unit 144 is normal display, the display control unit 143 causes the display unit 12 to display the acquired moving image and the direction information.

By configuring the information terminal 1 in this manner, the information terminal 1 can display a screen suitable for the display mode selected by the user. As a result, the user can view the performer's performance in a desired viewing mode according to the situation.

If the screen is configured so that the user can recognize the display mode that the user is viewing, it will be easier for the user to understand the direction in which the body should be moved. Therefore, the display control unit 143 may display the screen so that the selected display mode displays information that the user can understand.

The display control unit 143 causes the display unit 12 to display information indicating the selected display mode together with the front moving image. On the screens shown in FIGS. 3 and 4, the display control unit 143 displays an icon O4 indicating information corresponding to the selected display mode. As an example, the icon O4 is displayed as "normal" when the normal display is selected, and is displayed as "inverted" when the reverse display is selected.

Depending on the situation, the user may want to see moving images of the performer captured from various directions. Therefore, the information terminal 1 may be configured so that a moving image to be viewed can be selected from moving images captured from various directions. In the following, an example will be described in which the data processing system S is configured so that moving images captured from the front and rear can be viewed. Below, a moving image obtained by imaging a person performing a dance from behind is referred to as a rear moving image.

In this case, the display control unit 143 displays a screen for accepting selection of moving images to be displayed. The screens shown in FIGS. 3 and 4 have an icon O5 for selecting a moving image to be displayed. Since the front moving image is displayed at the display position O1 on the screens shown in FIGS. 3 and 4, an icon O5 for selecting the rear moving image is arranged.

The moving image selection unit 145 receives selection of a moving image to be displayed on the display unit 12 from the front moving image and the rear moving image, which is a moving image of a person performing a performance captured from behind. When the user performs an operation of pressing icon O5, moving image selection unit 145 accepts selection of a moving image. On the screen shown in FIG. 3, when the icon O5 for selecting the backward moving image is pressed, the moving image selection unit 145 accepts that the backward moving image has been selected.

The moving image acquisition unit 141 further acquires a backward moving image. When the backward moving image is selected, the moving image acquisition unit 141 acquires the backward moving image from the data processing device 2 .

The display control unit 143 causes the display unit 12 to display the rear moving image when the moving image selection unit 145 receives the selection of the rear moving image. The display control unit 143 causes the display unit 12 to display the backward moving image acquired based on the selection received by the moving image selection unit 145 . FIG. 5 is a diagram showing an example of a screen displayed by the display control unit 143 when a backward moving image is selected. On the screen shown in FIG. 5, the display control unit 143 displays the selected rear moving image at the display position O1. In the screen shown in FIG. 5, since the rear moving image is displayed at the display position O1, an icon O6 for selecting the front moving image is arranged.

By configuring the information terminal 1 in this manner, the user can view moving images of the performer captured from various directions depending on the situation.

Note that the moving image acquisition unit 141 may be configured to acquire both the forward moving image and the backward moving image. In this case, the display control unit 143 is configured to switch the moving image to be displayed among the acquired moving images based on the selection result received by the moving image selecting unit 145 .

Further, the information terminal 1 may configure the screen so as not to display the direction information when the backward moving image is displayed. By displaying in this way, the user can concentrate on the part that the user wants to check.

In this case, the display control unit 143 causes the display unit 12 to display both the forward moving image and the direction information when the moving image selecting unit 145 accepts the selection of the forward moving image. Then, when the moving image selection unit 145 receives the selection of the rear moving image, the display control unit 143 causes the display unit 12 to display the rear moving image and does not display the direction information on the display unit 12 . The display screen shown in FIG. 5 displays a screen without direction information.

By the way, various devices are used as the information terminal 1 used by the user. If the display area of the user's device is small, displaying a lot of directional information makes it difficult for the user to understand the motion. Therefore, the direction information may be prioritized for each part of the body. In this case, the information terminal 1 may be configured to control the direction information to be displayed based on priorities set in association with body parts.

The direction information acquisition unit 142 displays a plurality of direction information associated with information about a plurality of parts of the human body included in each frame and information indicating the direction in which each part faces, and the respective direction information. to get the priority and As an example, the relationship between direction information and priority is set in the data processing device 2 . For example, the performer sets the priority based on the importance of the program and the user's proficiency level. The priority is represented by a real number taking a value from 0 to 1, for example.

The display control unit 143 selects the direction information to be displayed based on the priority, and causes the display unit 12 to display the acquired front moving image and the selected one or more pieces of direction information. As an example, the display control unit 143 has a setting value indicating the maximum number of pieces of information indicating directions to be displayed on the display unit 12 at the same time. When the number of parts included in the acquired direction information exceeds the maximum value, the display control unit 143 selects parts of the set value in descending order of priority. The display control unit 143 displays the direction information of the selected part on the display unit 12 together with the moving image.

By configuring the information terminal 1 to control the direction information to be displayed based on priority, it is possible to display a screen that is easy for the user to understand even when the display area of the user's device is small.
