Abstract

According to an aspect, a display device includes a display unit and a control unit. The display unit stereoscopically displays a display object. When a movement of an object is detected in a three-dimensional space where the display object is stereoscopically displayed, the control unit for changes the display object in the three-dimensional space according to the movement of the object.

Claims

1. A display device, comprising:

a display unit for stereoscopically displaying a display object in a three-dimensional space;

a detecting unit for detecting an actual object in a three-dimensional space where the display object is stereoscopically displayed; and

a control unit for changing, when a movement of the actual object is detected in the three-dimensional space, a display form of the same display object according to the movement of the actual object and a type of the display object,

wherein

the detecting unit is configured to detect a state in which the actual object moves continuously from outside of the display object to inside thereof for a longer period of time than a predetermined time,

the control unit is configured to start changing the display object from when the movement of the actual object to the inside of the display object is detected, and

the control unit is configured to display, when the movement of the actual object to the inside of the display object becomes undetectable before the predetermined time elapses and after the display object is started to change, a reverse change such that the change of the display object is returned to its original state.

2. The display device according to claim 1, wherein

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

3. 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 actual object.

4. 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 actual object.

5. The display device according to claim 1, wherein

the detecting unit includes an imaging unit for photographing an image of the actual object.

6. The display device according to claim 1, wherein

the detecting unit includes a touch sensor for detecting a capacitance of the actual object.

7. The display device according to claim 1, wherein

the detecting unit includes an imaging unit for photographing an image of the actual object and a touch sensor for detecting a capacitance of the actual object, and

the control unit is configured to use a weighted average of a detection result via the imaging unit and a detection result via the touch sensor to specify the location of the actual object.

8. The display device according to claim 1, wherein

the type of the display object is any one selected from the group consisting of a rigid body, an elastic body, a plastic body, liquid, gas, and an aggregate.

9. The display device according to claim 1, wherein

the control unit is configured to change the display object according to a speed of the actual object in the movement of the actual object.

10. The display device according to claim 1, wherein

the display unit is further configured to display a bottom surface in the three-dimensional space, the bottom surface supporting the display object, and

the control unit is configured to change the display object while the display object is being supported by the bottom surface.
