Abstract

There is provided an information processing device including a display control section which causes a three-dimensional space in which an object is arranged to be displayed on a display screen, an acquisition section which acquires a pointing operation in the three-dimensional space, and a position setting section which sets a pointing position in the three-dimensional space on the basis of the pointing operation. The display control section displays the pointing position in the three-dimensional space, a difference of the pointing position from a position of the object in a depth direction of the display screen having been corrected.

Claims

1. An information processing device comprising:

a display control section which causes a three-dimensional space in which an object is arranged to be displayed on a display screen;

an acquisition section which acquires a pointing operation in the three-dimensional space; and

a position setting section which sets a pointing position in the three-dimensional space on the basis of the pointing operation,

wherein the display control section causes the pointing position to be displayed in the three-dimensional space at x-coordinate and y-coordinate positions corresponding to a point upon a surface of the displayed object, a difference between the pointing position and a position of the object in a depth direction of the display screen having been corrected by setting a z-coordinate depth position of the displayed object to correspond to a z-coordinate depth of the displayed object,

wherein the position setting section sets a provisional pointing position in the three-dimensional space on the basis of the pointing operation, and sets the pointing position on a reference line passing through the provisional pointing position and a reference point set in the three-dimensional space,

wherein the position setting section sets the pointing position at an intersection point between the object and the reference line, and

wherein the position setting section selects the object from among a plurality of objects each having an intersection point with the reference line, and sets the pointing position at the intersection point between the selected object and the reference line.

2. The information processing device according to claim 1, wherein the display control section causes a pointing line passing through the pointing position to be displayed on the reference line.

3. The information processing device according to claim 2, wherein the display control section causes the pointing line to be displayed as a line segment that starts at the reference point and ends at the pointing position.

4. The information processing device according to claim 1, wherein the display control section causes a cursor object to be displayed at the pointing position.

5. The information processing device according to claim 1, wherein

the acquisition section acquires an operation of switching a selection of the object, and

the position setting section switches the selected object on the basis of the operation of switching the selection of the object.

6. The information processing device according to claim 1, wherein the display control section causes a cursor object to be displayed at the pointing position with a blurred contour for visually correcting a difference in the depth direction by obscuring a boundary between the displayed object and the cursor object due to the blur.

7. The information processing device according to claim 1, wherein the display control section causes the three-dimensional space to be displayed on the display screen as a stereoscopic image.

8. The information processing device according to claim 1, wherein the reference point corresponds to a position of a hand of an operator that performs the pointing operation.

9. The information processing device according to claim 8, wherein the position of the hand of the operator to which the reference point corresponds is a location from which the operator specifies, through the pointing operation, the pointing position in the three-dimensional space.

10. An information processing comprising:

a display control section which causes a three-dimensional space in which an object is arranged to be displayed on a display screen;

an acquisition section which acquires a pointing operation in the three-dimensional space; and

a position setting section which sets a pointing position in the three-dimensional space on the basis of the pointing operation,

wherein the display control section causes the pointing position to be displayed in the three-dimensional space at x-coordinate and y-coordinate positions corresponding to a point upon a surface of the displayed object, a difference between the pointing position and a position of the object in a depth direction of the display screen having been corrected by setting a z-coordinate depth position of the displayed object to correspond to a z-coordinate depth of the displayed object,

wherein the position setting section sets a provisional pointing position in the three-dimensional space on the basis of the pointing operation, and sets the pointing position on a reference line passing through the provisional pointing position and a reference point set in the three-dimensional space, and

wherein the position setting section, when there is no intersection point between the object and the reference line, sets the pointing position on the basis of positions of one or more objects located around the reference line.

11. An information processing comprising:

a display control section which causes a three-dimensional space in which an object is arranged to be displayed on a display screen;

an acquisition section which acquires a pointing operation in the three-dimensional space; and

a position setting section which sets a pointing position in the three-dimensional space on the basis of the pointing operation,

wherein the display control section causes the pointing position to be displayed in the three-dimensional space at x-coordinate and y-coordinate positions corresponding to a point upon a surface of the displayed object, a difference between the pointing position and a position of the object in a depth direction of the display screen having been corrected by setting a z-coordinate depth position of the displayed object to correspond to a z-coordinate depth of the displayed object,

wherein the position setting section sets a provisional pointing position in the three-dimensional space on the basis of the pointing operation, and sets the pointing position on a reference line passing through the provisional pointing position and a reference point set in the three-dimensional space, and

wherein the acquisition section acquires an operation of moving the reference point, and the position setting section moves the reference point on the basis of the operation of moving the reference point.

12. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute the processes of:

causing a three-dimensional space in which an object is arranged to be displayed on a display screen;

acquiring a pointing operation in the three-dimensional space;

setting a pointing position in the three-dimensional space on the basis of the pointing operation; and

causing the pointing position to be displayed in the three-dimensional space at x-coordinate and y-coordinate positions corresponding to a point upon a surface of the displayed object, a difference between the pointing position and a position of the object in a depth direction of the display screen having been corrected by setting a z-coordinate depth position of the displayed object to correspond to a z-coordinate depth of the displayed object,

wherein a provisional pointing position is set in the three-dimensional space on the basis of the pointing operation, and the pointing position is set on a reference line passing through the provisional pointing position and a reference point set in the three-dimensional space,

wherein the pointing position is set at an intersection point between the object and the reference line, and

wherein the object is selected from among a plurality of objects each having an intersection point with the reference line, and the pointing position is set at the intersection point between the selected object and the reference line.

13. The non-transitory computer-readable medium according to claim 12, wherein the reference point corresponds to a position of a hand of an operator that performs the pointing operation.

14. An information processing method comprising:

causing a three-dimensional space in which an object is arranged to be displayed on a display screen;

acquiring a pointing operation in the three-dimensional space;

setting a pointing position in the three-dimensional space on the basis of the pointing operation; and
