Abstract

According to an aspect, a display device includes a display unit, a detecting, and a control unit. The display unit has a display surface and is configured to three-dimensionally display a display object in a space on a back face side of the display surface. The detecting unit detects an action of an object in the space on the back face side. When the detecting unit detects a predetermined action of the object in the space on the back face side, the control unit changes the display object in the space on the back face side according to the predetermined action.

Claims

1. A display device comprising:

a display unit that has a display surface and is configured to three-dimensionally display a display object in a space on a back face side of the display surface;

a detecting unit for detecting an action of an object in the space on the back face side; and

a control unit for changing, when the detecting unit detects a predetermined action of the object in the space on the back face side, the display object in the space on the back face side according to the predetermined action.

2. The display device according to claim 1, wherein

the display unit is configured to transmit light at least from the back face side of the display surface to a front face side thereof.

3. The display device according to claim 1, further comprising a stand portion for standing the display unit.

4. The display device according to claim 1, wherein

the display unit is configured to three-dimensionally display a display object further in a space on a front face side of the display surface, and

when the detecting unit detects a predetermined action of the object in the space on the back face side,

the control unit is configured to cause a display object, which is three-dimensionally displayed in the space on the back face side of the display surface by the display unit, to be displayed across the space on the front face side of the display surface and the space on the back face side of the display surface.

5. The display device according to claim 1, wherein

the detecting unit is configured to detect a first state in which the object is moved from outside of the display object to inside thereof, and

the control unit is configured to change, when the first state is detected, the display object in the space according to the action of the object.

6. The display device according to claim 1, wherein

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

the control unit is configured to change, after the second state is detected, the display object in the space according to the action of the object.

7. The display device according to claim 1, wherein

the detecting unit is configured to detect a third state in which a movement of the object from outside of the display object to inside thereof continues for a longer period of time than a predetermined time, and

the control unit is configured to change, when the third state is detected, the display object in the space according to the action of the object.

8. The display device according to claim 1, wherein

the detecting unit is configured to detect a fourth state in which a movement of the object from outside of the display object to inside thereof continues for a longer period of time than a predetermined time, and

the control unit is configured to start to change the display object at a time of detecting the movement of the object to the inside of the display object.

9. The display device according to claim 6, wherein, when the movement of the object to the inside of the display object becomes undetectable after starting to change the display object and before elapse of the predetermined time,

the control unit is configured to display a reverse change to return the changed display object to its original state.

10. The display device according to claim 1, wherein

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

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

11. The display device according to claim 1, wherein

the detecting unit is configured to detect a sixth state in which the display object is located between a first object and a 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 sixth state is detected.

12. The display device according to claim 1, wherein

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

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

13. The display device according to claim 1, wherein

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

the control unit is configured to start to change the display object at a time of detecting the movement.

14. The display device according to claim 13, wherein, when it is detected that the display object is located between the first object and the second object and thereafter at least one of the first object and the second object is moved, and the distance between the first object and the second object is increased before the elapse of the predetermined time,

the control unit is configured to display a reverse change to return the changed display object to its original state.

15. The display device according to claim 1, wherein the detecting unit is configured to detect the action of the object through detection of capacitance.

16. The display device according to claim 1, wherein the detecting unit is configured to detect the action of the object through detection of either one of visible light and invisible light.
