Abstract

A display control apparatus controls display of a transparent display which includes a screen configured to transmit light arriving from an object located on a side of a second surface so that the object is viewable from a viewpoint located on a side of a first surface which is an opposite surface to the second surface. The display control apparatus includes: an acquisition unit that acquires position information indicating relative positional relations between the transparent display and the viewpoint and between the transparent display and the object; and a display control unit that controls the display of the transparent display based on the position information.

Claims

1. A display control apparatus controlling display of a transparent display which includes a screen configured to transmit light arriving from an object located on a side of a second surface so that the object is viewable from a viewpoint located on a side of a first surface which is an opposite surface to the second surface, the apparatus comprising:

an acquisition unit that acquires position information indicating relative positional relations between the transparent display and the viewpoint and between the transparent display and the object; and

a display control unit that controls the display of the transparent display based on the position information.

2. The display control apparatus according to claim 1, wherein the display control unit controls the display of the transparent display based on the position information by determining a display position or a display attribute of a display object displayed on the screen of the transparent display.

3. The display control apparatus according to claim 1, wherein the display control unit controls the display of the transparent display so that the object is viewable from the viewpoint through the screen of the transparent display.

4. The display control apparatus according to claim 3, wherein the display control unit determines a region on the screen of the transparent display based on the position information and controls the display of the transparent display so that the object is viewable from the viewpoint through the region.

5. The display control apparatus according to claim 4, wherein the determined region includes an intersection point between the screen of the transparent display and a straight line passing through a position of the viewpoint and a position of the object in the position information or is present around the intersection point.

6. The display control apparatus according to claim 4, wherein the display control unit controls the display of the transparent display by causing a display object to be not displayed in the determined region.

7. The display control apparatus according to claim 4, wherein the display control unit controls the display of the transparent display by setting a display attribute of a display object in the determined region as a display attribute in which the object is viewable from the viewpoint.

8. The display control apparatus according to claim 6, wherein the display object is a display object of which a display position is changed through an operation of a user.

9. The display control apparatus according to claim 3,

wherein the viewpoint includes two or more viewpoints, and

the display control unit controls the display of the transparent display so that the object is viewable from at least one of the two or more viewpoints.

10. The display control apparatus according to claim 2, wherein the display control unit changes the display position or the display attribute of the display object in accordance with a change in a relative position of the viewpoint with respect to the transparent display or a relative position of the object with respect to the transparent display in the position information.

11. The display control apparatus according to claim 10, wherein the display control unit changes the display position of the display object in accordance with a change in a position of an intersection point between the screen of the transparent display and a straight line passing through a position of the viewpoint and a position of the object in the position information.

12. The display control apparatus according to claim 2,

wherein the transparent display displays the display object so as to be stereoscopically viewable, and

the display control unit determines the display position or the display attribute of the display object for a stereoscopic view based on the position information.

13. The display control apparatus according to claim 12, wherein the display control unit determines the display position of the display object for the stereoscopic view so that the display object is stereoscopically viewed with a depth in a direction from the side of the first surface of the transparent display to the side of the second surface of the transparent display.

14. The display control apparatus according to claim 12, wherein the display control unit changes the display position or the display attribute of the display object for the stereoscopic view in accordance with a change in a position of the viewpoint or a position of the object in the position information.

15. The display control apparatus according to claim 12, wherein the display control unit causes a display object to be displayed to make a person located on the side of the first surface of the transparent display aware of a presence of the transparent display.

16. The display control apparatus according to claim 15,

wherein the acquisition unit additionally acquires a first distance between the transparent display and the person or a part of a body of the person, and

the display control unit causes the display object to be displayed to make the person aware of the presence of the transparent display in accordance with the first distance.

17. The display control apparatus according to claim 16, wherein the display control unit causes the display object to be displayed to make the person aware of the presence of the transparent display, even when the shorter a second distance between a position of the transparent display and a position of the object in the position information is, the longer the first distance is.

18. The display control apparatus according to claim 1,

wherein the viewpoint is eyes of a person located on the side of the first surface of the transparent display, and

the display control apparatus recognizes a relative position of the viewpoint with respect to the transparent display or the object by recognizing a relative position of a face of the person with respect to the transparent display or the object.

19. A display control method of controlling display of a transparent display which includes a screen configured to transmit light arriving from an object located on a side of a second surface so that the object is viewable from a viewpoint located on a side of a first surface which is an opposite surface to the second surface, the display control method comprising:

acquiring position information indicating relative positional relations between the transparent display and the viewpoint and between the transparent display and the object; and

controlling the display of the transparent display based on the position information.

20. A computer program for causing a computer, which is directly or indirectly connected to a transparent display which includes a screen configured to transmit light arriving from an object located on a side of a second surface so that the object is viewable from a viewpoint located on a side of a first surface which is an opposite surface to the second surface, to execute:

acquiring position information indicating relative positional relations between the transparent display and the viewpoint and between the transparent display and the object; and

controlling the display of the transparent display based on the position information.
