  The determination unit 53 determines whether or not the button of the controller 200 has been operated (step S23).

  When the button of the controller 200 has been operated (YES in step S23), the determination unit 53 selects a voice corresponding to the line-of-sight direction (step S24), and the output unit 54 outputs the selected voice (step S25).

  FIG. 9 shows an example of the title screen. On the title screen 70 shown in FIG. 9, a title logo 71 and silhouettes of eight characters 72A to 72D and 72F to 72I appearing in the game are arranged. Below the title logo 71, a message (PRESS ANY BUTTON) prompting the operation of the buttons of the controller 200 is displayed. A movie may be played on the background of the title logo 71.

  The title screen 70 is displayed in a large size at a fixed position (in front of the user) in the celestial sphere of the virtual three-dimensional space. The user can confirm the entire title screen 70 by turning his / her head left and right. When the user operates a button on the controller 200 while the title screen 70 is displayed, the game main part starts after the voice selected based on the viewing direction is output.

  The title screen 70 of FIG. 9 is divided into nine areas 73A to 73I. When the user operates a button on the controller 200, the determination unit 53 selects a voice corresponding to the areas 73A to 73I indicated by the line-of-sight direction. In the example of FIG. 9, eight areas 73A to 73D and 73F to 73I correspond to eight characters 72A to 72D and 72F to 72I. When the line-of-sight direction indicates any of the areas 73A to 73D and 73F to 73I, the voice whose title is called by the voices of the characters 72A to 72D and 72F to 72I corresponding to the areas 73A to 73D and 73F to 73I is selected. Is done. When the line-of-sight direction indicates the region 73E, a voice whose title is called by a voice other than the eight characters 72A to 72D and 72F to 72I is selected.

  On the title screen 70, the silhouettes of the characters 72 </ b> A to 72 </ b> D and 72 </ b> F to 72 </ b> I indicated by the line-of-sight direction may be displayed darkly in accordance with the movement of the line of sight. Similar to the first embodiment, the silhouette may be moved forward.

  As described above, according to the present embodiment, the title screen is divided into a plurality of areas, and when the user operates the button of the controller 200, the title is called with the voice corresponding to the area indicated by the line-of-sight direction. Thus, the effect can be changed according to the user's line-of-sight direction.

[Third Embodiment]
In the third embodiment, the line-of-sight direction during the game is determined, and an additional effect is performed if the user is looking at a predetermined range at the end of the game or when switching scenes or stages.

  In the VR game using the HMD 300, a virtual three-dimensional space for 360 degrees is prepared. However, the user can see only the space in the line-of-sight direction. Therefore, in the present embodiment, as a Easter / Egg element, when the user is looking at a predetermined range in the virtual three-dimensional space, the effect after the main game is changed in relation to the predetermined range. Note that the present embodiment is not limited to a game, and can be similarly applied when a user views a 360 degree panoramic movie with the HMD 300.

  FIG. 10 is a flowchart showing the flow of processing of the determination unit.

  As in the first and second embodiments, the input unit 51 inputs HMD information, and the camera control unit 52 sets the orientation of the virtual camera based on the orientation of the user's head. The output unit 54 generates an image corresponding to the orientation of the virtual camera and outputs it to the HMD 300.

  In the present embodiment, the determination unit 53 determines whether or not a predetermined range is displayed in the image (step S31). If the predetermined range is displayed (YES in step S31), the user determines the predetermined range. A flag indicating that the user has been viewed is set (step S32).

  For example, assume that a predetermined range 81 is set on a signboard in the screen 80 of FIG. Since the predetermined range 81 is in the screen 80, the user sets a flag on the assumption that the user has seen the signboard in the screen 80. The predetermined range may be set corresponding to a hidden object or item.

  After the game is over, the determination unit 53 determines whether or not a flag is set. If the flag is not set, a normal effect is performed. If the flag is set, the effect is changed or added. For example, when the user is not looking at the signboard (when the flag is not set), a normal presentation is performed. When the user is looking at the signboard (when the flag is set), text related to the contents of the signboard is displayed. indicate. You may display the image and moving image relevant to the content of the signboard.

  Regarding the determination to set the flag, whether or not a part of the predetermined range is displayed on the screen, whether or not the entire predetermined range is displayed on the screen, or the line-of-sight direction indicates the predetermined range. Or not. Moreover, it is good also as conditions, such as whether the predetermined range was displayed even for a moment, whether the predetermined range was displayed more than predetermined time, etc.

  A plurality of predetermined ranges may be set in the game. In that case, the effect may be changed based on the number of discoveries in the predetermined range (the number of standing flags). Or you may change an effect based on the discovered predetermined range. For example, when the user views two objects A and B set as a predetermined range, after the game is over, an effect related to each of the objects A and B may be added, or either the object A or the object B Only an effect related to one side may be added.

  Further, the progress of the game may be changed according to the result of the flag. For example, after a certain game scene or stage is finished, an effect is given according to the flag result, and the next game scene or stage is branched according to the flag result. Thereby, a story can be changed according to the situation whether a user has seen or not seen a certain object. Alternatively, even during the game scene, the presentation may be changed according to the result of the flag.

  As described above, according to the present embodiment, an object hidden by the user is determined by determining the direction of the user's line of sight in the game and setting a flag, and changing the presentation according to the result of the flag after the game ends. And can give fun to discover items. In addition, the user can be directed to see various places in the virtual three-dimensional space.
