Abstract

According to an aspect, an electronic device includes: a display unit for three-dimensionally displaying a first object; a detecting unit for detecting a displacement of a second object in three-dimensional space where the first object is displayed; and a control unit for performing an operation related to the first object according to the displacement of the second object detected by the detecting unit.

First claim

The invention claimed is:

1. An electronic device, comprising:
a display unit configured to stereoscopically display a first object to appear as a three-dimensional object floating in a three-dimensional space above the display unit;
a detecting unit configured to detect a displacement of a second object in the three-dimensional space above the display unit;
a control unit configured to perform an operation related to the first object according to the displacement of the second object detected by the detecting unit; and
a projecting unit configured to project an image related to the first object,
wherein
the detecting unit is configured to detect, in the three-dimensional space, a position on which the second object touches the first object,
the control unit is configured to change the image projected by the projecting unit according to the position,
the detecting unit includes an imaging unit,
an angle of view and a layout of the imaging unit are configured to capture the second object no matter where the second object is placed over the display unit, and
when the detecting unit detects that the second object moves the first object toward a plane of the display unit, the control unit is configured to reduce a size of the first object which is stereoscopically displayed according to an amount by which the second object moves the first object toward the plane of the display unit.

2. The electronic device according to claim 1 , wherein
when the detecting unit detects a displacement in which the second object moves along the first object, the control unit is configured to rotate the first object corresponding to a movement direction of the second object.

3. The electronic device according to claim 2 , wherein the control unit is further configured to rotate the first object by an angle according to a movement amount of the operation.

4. The electronic device according to claim 1 , wherein
when the detecting unit detects an operation in which the second object contacts the first object and then separates from the first object, the control unit executes a process corresponding to the position on which the first object is contacted by the second object.

5. The electronic device according to claim 2 , wherein when the detecting unit detects the displacement in which the second object moves along the first object, the control unit is further configured to rotate the image, that is projected by the projecting unit and related to the first object, corresponding to the movement direction of the second object.

6. The electronic device according to claim 1 , wherein the detecting unit further includes a capacitive touch sensor.

7. The electronic device according to claim 1 , wherein when the detecting unit detects the second object moves toward the plane of the display unit in the vertical direction, the control unit is further configured to reduce a size of the image that is projected by the projecting unit and related to the first object.

8. The electronic device according to claim 1 , wherein the control unit is configured to change the first object and the image according to the position on which the second object touches the first object.

9. The electronic device according to claim 8 , wherein the control unit is configured to change the image according to the changed first object.

10. The electronic device according to claim 1 , wherein the detecting unit includes proximity sensors configured to detect a movement of the second object in a planar direction in the three-dimensional space in a noncontact manner with the second object when the proximity sensors are arranged substantially parallel with a movement direction of the second object.

11. An electronic device, comprising:
a first display unit configured to stereoscopically display a first object to appear as a three-dimensional object floating in a three-dimensional space above the display unit;
a detecting unit configured to detect a displacement of a second object in the three-dimensional space above the first display unit;
a control unit configured to perform an operation related to the first object according to the displacement of the second object detected by the detecting unit; and
a second display unit configured to display an image related to the first object,
wherein
the detecting unit is configured to detect, in the three-dimensional space, a position on which the second object touches the first object,
the control unit is configured to change the image related to the first object and displayed on the second display unit according to the position,
the detecting unit includes an imaging unit,
an angle of view and a layout of the imaging unit are configured to capture the second object no matter where the second object is placed over the first display unit, and
when the detecting unit detects that the second object moves the first object toward a plane of the first display unit, the control unit is configured to reduce a size of the first object which is stereoscopically displayed according to an amount by which the second object moves the first object toward the plane of the first display unit.

12. The electronic device according to claim 11 , wherein
when the detecting unit detects a displacement in which the second object moves along the first object, the control unit is configured to rotate the first object corresponding to a movement direction of the second object.

13. The electronic device according to claim 12 , wherein when the detecting unit detects the displacement in which the second object moves along the first object, the control unit is further configured to rotate the image, that is displayed by the second display unit and related to the first object, corresponding to the movement direction of the second object.

14. The electronic device according to claim 11 , wherein when the detecting unit detects the second object moves toward the plane of the display unit in the vertical direction, the control unit is further configured to reduce a size of the image that is displayed by the second display unit and related to the first object.

15. The electronic device according to claim 11 , wherein the detecting unit includes proximity sensors configured to detect a movement of the second object in a planar direction in the three-dimensional space in a noncontact manner with the second object when the proximity sensors are arranged substantially parallel with a movement direction of the second object.
