Abstract

To improve retrieval performance of an object displayed in the visual field of the user. There is provided a display control apparatus including a display control unit configured to display an object corresponding to at least one of a yaw angle and a pitch angle of a display unit in a visual field of a user. The display control unit is capable of operating in a first mode in which a position of the object in the visual field is not dependent on a roll angle of the display unit.

Claims

1. A display control apparatus comprising

a display control unit configured to display an object corresponding to at least one of a yaw angle and a pitch angle of a display unit in a visual field of a user,

wherein the display control unit is capable of operating in a first mode in which a position of the object in the visual field is not dependent on a roll angle of the display unit.

2. The display control apparatus according to claim 1, wherein

the display control unit is capable of operating in a second mode in which the position of the object in the visual field is dependent on the roll angle.

3. The display control apparatus according to claim 2, wherein

the display control unit selects, as an operation mode, any one of the first mode and the second mode.

4. The display control apparatus according to claim 3, wherein

the display control unit selects, as the operation mode, any one of the first mode and the second mode on the basis of operation performed by a user.

5. The display control apparatus according to claim 3, wherein

in the case where the object is capable of accepting operation performed by a user, the display control unit selects the first mode as the operation mode.

6. The display control apparatus according to claim 3, wherein

in the case where the object is a three-dimensional object, the display control unit selects the second mode as the operation mode.

7. The display control apparatus according to claim 3, wherein

the display control unit selects, as the operation mode, any one of the first mode and the second mode on the basis of ability of the display control apparatus.

8. The display control apparatus according to claim 1, wherein

while operating in the first mode, the display control unit does not cause an orientation of the object in the visual field to depend on the roll angle.

9. The display control apparatus according to claim 1, wherein

while operating in the first mode, the display control unit causes an orientation of the object in the visual field to depend on the roll angle.

10. The display control apparatus according to claim 2, wherein

while operating in the second mode, the display control unit rotates the object in the visual field in a direction opposite to a direction of the roll angle to an extent that is the same as the roll angle.

11. The display control apparatus according to claim 10, wherein

while operating in the second mode, in the case where the roll angle exceeds a predetermined angle, the display control unit rotates the position of the object in the visual field in a direction opposite to a direction of the roll angle to an extent that is the same as the predetermined angle.

12. The display control apparatus according to claim 11, wherein

while operating in the second mode, in the case where the roll angle exceeds a predetermined angle, the display control unit gradually moves the position of the object in the visual field, from a position at which the display control unit rotates the position of the object in the visual field in a direction opposite to a direction of the roll angle to an extent that is the same as the roll angle to a position at which the display control unit rotates the position of the object in the visual field in the direction opposite to the direction of the roll angle to the extent that is the same as the predetermined angle.

13. The display control apparatus according to claim 11, wherein

in the case where a period over which the extent of the roll angle has exceeded a threshold continues for a predetermined period, the display control unit updates the predetermined angle.

14. The display control apparatus according to claim 11, wherein

in the case where a shape of the visual field satisfies a predetermined condition, the display control unit updates the predetermined angle.

15. The display control apparatus according to claim 2, wherein

while operating in the second mode, the display control unit causes an orientation of the object in the visual field to depend on the roll angle.

16. The display control apparatus according to claim 1, wherein

the display control unit causes at least the object corresponding to the pitch angle to be displayed in the visual field, and

the pitch angle corresponding to the object is limited within a predetermined range.

17. The display control apparatus according to claim 1, wherein

in the case where the object is a three-dimensional object, the display control unit displays an object on which image processing is performed in the visual field.

18. The display control apparatus according to claim 1, wherein

in the case where the object is a two-dimensional image, the display control unit displays an object on which image processing is not performed in the visual field.

19. A display control method comprising

displaying an object corresponding to at least one of a yaw angle and a pitch angle of a display unit in a visual field of a user,

wherein operation is possible in a first mode in which a position of the object in the visual field is not dependent on a roll angle of the display unit.

20. A program for causing a computer to function as a display control apparatus including

a display control unit configured to display an object corresponding to at least one of a yaw angle and a pitch angle of a display unit in a visual field of a user,

wherein the display control unit is capable of operating in a first mode in which a position of the object in the visual field is not dependent on a roll angle of the display unit.
