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.

First claim

What is claimed is:

1. A display device, comprising:
a display unit configured to stereoscopically display a display object at an initial position;
a detecting unit configured to detect a first object and a second object in a three-dimensional space where the display object is three-dimensionally visible; and
a control unit configured to
set the display object to a tentatively selected state in response to a detection of a first arrangement in which the display object at the initial position is located between the first object and the second object in the three-dimensional space,
maintain the display object, that has been set to the tentatively selected state, at the initial position,
when the first object and the second object move from the first arrangement to a second arrangement in which a relative position of the first and second objects to said display object is different from the first arrangement, and then

move the display object from the initial position to a position between the first object and the second object,
when a distance between the first object and the second object is not widened for a longer period of time than a predetermined time in the second arrangement.

2. The display device according to claim 1 , wherein
the first arrangement 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 deform the display object in accordance with a movement of the first object or the second object.

11. The display device according to claim 1 , wherein
the control unit is configured to delete the display object in accordance with a movement of the first object or the second object.

12. A display device, comprising:
a display unit configured to stereoscopically display a display object at an initial position;
a detecting unit configured to detect a first object and a second object in a three-dimensional space where the display object is three-dimensionally visible; and
a control unit configured to
set the display object to a tentatively selected state in response to a detection of a first arrangement in which at least one of the first object and the second object is in contact with the display object at the initial position in the three-dimensional space,
maintain the display object, that has been set to the tentatively selected state, at the initial position,
when the first object and the second object move from the first arrangement to a second arrangement in which a relative location of the first and second objects to said display object is different from the first arrangement, and then

move the display object from the initial position to a position between the first object and the second object where the display object is again in contact with said at least one of the first object and the second object that was in contact with the display object in the first arrangement,
when a distance between the first object and the second object is not widened for a longer period of time than a predetermined time in the second arrangement.

13. The display device according to claim 12 , wherein
the first arrangement in which said at least one of the first object and the second object 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 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
it is detected that the distance between the first object and the second object is widened before the predetermined time elapses.

17. The display device according to claim 16 , wherein
the control unit is configured to display the reverse change in a shorter time than a time taken by
