Abstract

According to an aspect, a display device includes a display unit, a detecting unit, and a control unit. The display unit stereoscopically displays a display object. The detecting unit detects a first object and a second object in a three-dimensional space where the display object is displayed. The control unit changes the display object when a case is detected in which the display object is located between the first object and the second object in the three-dimensional space.

Claims

1. A display device comprising:

a display unit for stereoscopically displaying a display object;

a detecting unit for detecting a first object and a second object in a three-dimensional space where the display object is displayed; and

a control unit for changing the display object when a case is detected in which the display object is located between the first object and the second object in the three-dimensional space.

2. The display device according to claim 1, wherein

the case in which the display object is located between the first object and the second object includes a case in which a line connecting between the first object and the second object intersects a display surface of the display unit.

3. The display device according to claim 1, wherein

the detecting unit is configured to detect a first state in which the display object is located between the first object and the second object, and

the control unit is configured to change the display object when the first state is detected.

4. The display device according to claim 1, wherein

the detecting unit is configured to detect a second state in which the display object is located between the first object and the second object for a longer period of time than a predetermined time, and

the control unit is configured to change the display object when the second state is detected.

5. The display device according to claim 1, wherein

the detecting unit is configured to detect a third state in which the display object is located between the first object and the second object and a distance between the first object and the second object is not widened for a longer period of time than a predetermined time, and

the control unit is configured to change the display object when the third state is detected.

6. The display device according to claim 1, wherein

the detecting unit is configured to detect a fourth state in which at least one of the first object and the second object is moved after the display object is located between the first object and the second object and a distance between the first object and the second object is not widened for a longer period of time than a predetermined time, and

the control unit is configured to start changing the display object from when the movement is detected.

7. The display device according to claim 6, wherein,

the control unit is configured to display a reverse change representing that the change of the display object is returned to its original state, when at least one of the first object and the second object is moved after the display object is located between the first object and the second object and the distance between the first object and the second object is widened before the predetermined time elapses.

8. The display device according to claim 7, wherein

the control unit is configured to display the reverse change in a shorter time than a time taken by the change.

9. The display device according to claim 1, wherein

the control unit is configured to change the display object by moving or rotating the display object or by combining the movement and the rotation with a movement of the first object or the second object.

10. The display device according to claim 1, wherein

the control unit is configured to change the display object by deforming the display object with a movement of the first object or the second object.

11. The display device according to claim 1, wherein

the control unit changes the display object by deleting the display object with a movement of the first object or the second object.

12. A display device comprising:

a display unit for stereoscopically displaying a display object;

a detecting unit for detecting a first object and a second object in a three-dimensional space where the display object is displayed; and

a control unit for changing the display object when a case is detected in which at least one of the first object and the second object is located in a position where it is in contact with the display object in the three-dimensional space.

13. The display device according to claim 12, wherein

the case in which at least one of the first object and the second object is located in the position where it is in contact with the display object in the three-dimensional space includes a case in which a line connecting between the first object and the second object intersects a display surface of the display unit.

14. The display device according to claim 12, wherein

the detecting unit is configured to detect a first state in which at least one of the first object and the second object is in contact with the display object for a longer period of time than a predetermined time, and

the control unit is configured to change the display object when the first state is detected.

15. The display device according to claim 12, wherein

the detecting unit is configured to detect a second state in which at least one of the first object and the second object is in contact with the display object and a distance between the first object and the second object is not widened for a longer period of time than a predetermined time, and

the control unit is configured to change the display object when the second state is detected.

16. The display device according to claim 12, wherein

the detecting unit is configured to detect a third state in which at least one of the first object and the second object is moved after at least one of the first object and the second object is brought into contact with the display object and a distance between the first object and the second object is not widened for the longer period of time than the predetermined time, and

the control unit is configured to start changing the display object from when the movement is detected.

17. The display device according to claim 16, wherein,

the control unit is configured to display a reverse change representing that the change of the display object is returned to its original state, when at least one of the first object and the second object is moved after at least one of the first object and the second object is brought into contact with the display object and if it is detected that the distance between the first object and the second object is widened before the predetermined time elapses.

18. The display device according to claim 17, wherein

the control unit is configured to display the reverse change in a shorter time than a time taken by the change.

19. The display device according to claim 12, wherein

the control unit is configured to change the display object by moving or rotating the display object or by combining the movement and the rotation with a movement of the first object or the second object.

20. The display device according to claim 12, wherein

the control unit is configured to change the display object by deforming the display object with a movement of the first object or the second object.

21. The display device according to claim 12, wherein

the control unit is configured to change the display object by deleting the display object with a movement of the first object or the second object.

22. A display device comprising:

a display unit for stereoscopically displaying a display object; and

a control unit for changing the display object when a first object and a second object are located in positions where the display object is sandwiched therebetween in a three-dimensional space where the display object is displayed.

23. A display device comprising:

a display unit for displaying a display object on its display surface;

a detecting unit for detecting a first object and a second object on the display surface; and

a control unit for changing the display object when it is detected that the display object is located between the first object and the second object on the display surface.

24. A display device comprising:

a display unit for displaying a display object on its display surface;

a detecting unit for detecting a first object and a second object on the display surface; and

a control unit for changing the display object when it is detected that at least one of the first object and the second object is located in a position where it is in contact with the display object on the display surface.
