Display control method and system for executing the display control method
A method includes defining a virtual space including a virtual camera, a character object, and a field in which the character object is movable, the field defining a peripheral direction and surrounding the virtual camera along the peripheral direction. The method includes defining a visual field of the virtual camera. The method includes displaying a visual-field image on a head-mounted display based on the visual field. The method includes detecting a movement input including a lateral-direction component, the lateral-direction being different from the peripheral direction. The method includes moving the character object in the field along the peripheral direction in response to the lateral-direction component of the movement input. The method includes detecting movement of the head-mounted display and changing a direction of the virtual camera based on detected movement of the head-mounted display. The method includes updating the visual-field image based on the direction of the virtual camera.
1. A method comprising:
defining a virtual space including a virtual camera, a character object, and a field in which the character object is movable, the field defining a peripheral direction and surrounding the virtual camera along the peripheral direction;
defining a visual field of the virtual camera;
displaying a visual-field image on a head-mounted display based on the visual field and the virtual space;
detecting a movement input including a lateral-direction component, the lateral-direction being different from the peripheral direction;
moving the character object in the field along the peripheral direction in response to the lateral-direction component of the movement input;
detecting movement of the head-mounted display; changing a direction of the virtual camera based on detected movement of the head-mounted display;
updating the visual-field image based on the direction of the virtual camera.
2. The method according to claim 1 , further comprising restricting a movable range of the character object along the peripheral direction in response to a predetermined condition being satisfied.
3. The method according to claim 2 , wherein the predetermined condition comprises a type of a competitive game or an elapsed time in at least one round of the competitive game.
4. The method according to claim 2 , wherein the restricting of the moveable range comprises changing the movable range of the character object depending on a level of a round in a game or an elapsed time in the round.
5. The method according to claim 2 , wherein the restricting of the moveable range comprises placing a wall object in the field, the wall object restricting the movable range.
6. The method according to claim 2 , wherein the restricting of the moveable range comprises changing a shape of the field, the shape being determined for restricting the movable range.
7. The method according to claim 1 , wherein the updating of the visual-field image comprises changing the direction of the virtual camera in synchronization with the movement of the head-mounted display without changing a position of the virtual camera.
8. The method according to claim 1 , further comprising prohibiting the character object from moving in a depth direction of the visual field in the field in response to the movement input.
9. A method comprising:
defining a virtual space including a virtual camera, a character object, and a field in which the character object is movable, the field defining a peripheral direction and surrounding the virtual camera along the peripheral direction;
defining a visual field of the virtual camera;
displaying a visual-field image on a head-mounted display based on the visual field and the virtual space;
detecting a movement input;
moving the character object in the field along the peripheral direction in response to the movement input;
detecting movement of the head-mounted display;
changing a direction of the virtual camera based on a detected movement of the head-mounted display, wherein the changing the direction of the virtual camera comprises changing the direction of the virtual camera in synchronization with the movement of the head-mounted display without changing a position of the virtual camera in the virtual space
updating the visual-field image based on the direction of the virtual camera.
10. The method according to claim 9 , wherein
the movement input including a lateral-direction component, the lateral-direction being different from the peripheral direction;
the moving of the character object comprises moving the character object in the peripheral direction in response to the lateral-direction component.
11. A system comprising:
a head-mounted display; and
a processor, wherein the processor is configured to execute instructions stored on a non-transitory computer readable medium for:
providing instructions for defining a virtual space including a virtual camera, a character object, and a field in which the character object is movable, the field defining a peripheral direction and surrounding the virtual camera along the peripheral direction;
providing instructions for defining a visual field of the virtual camera;
providing instructions for displaying a visual-field image on the head-mounted display based on the visual field of the virtual camera and the virtual space;
detecting a movement input including a lateral-direction component, the lateral-direction being different from the peripheral direction;
providing instructions for moving the character object in the field along the peripheral direction in response to the lateral-direction component of the movement input;
detecting movement of the head-mounted display; providing instructions for changing a direction of the virtual camera based on detected movement of the head-mounted display;
updating the visual-field image based on the direction of the virtual camera.
