Abstract

A transparent display apparatus includes a transparent display which displays a virtual object, a first detector which detects a position of a real object placed in a first direction from the transparent display, a second detector which detects a position of a user in a second direction from the transparent display, and a controller which estimates distances of the real object and the virtual object with respect to the position of the user, and an overlapping area of the real object and the virtual object on the transparent display with respect to the position of the user based on the detected position of the real object, the detected position of the user and the position of the virtual object. The controller controls the transparent display to display the virtual object on the overlapping area based on the distances of the real object and the virtual object regarding the user position.

Claims

1. A transparent display apparatus, comprising:

a transparent display which displays a virtual object having a predetermined position on a virtual dimensional area;

a first detector which detects a position of a real object placed in a first direction from the transparent display;

a second detector which detects a position of a user in a second direction from the transparent display; and

a controller which estimates distances of the real object and the virtual object with respect to the position of the user, and an overlapping area of the real object and the virtual object on the transparent display with respect to the position of the user based on the detected position of the real object, the detected position of the user and the predetermined position of the virtual object,

wherein the controller controls the transparent display to display the virtual object on the overlapping area based on the distances of the real object and the virtual object regarding the position of the user.

2. The transparent display apparatus of claim 1, wherein the controller displays the virtual object on the overlapping area, if the distance of the virtual object regarding the position of the user is closer than the distance of the real object regarding the position of the user, and does not display the virtual object on the overlapping area, if the distance of the virtual object regarding the position of the user is longer than the distance of the real object regarding the position of the user.

3. The transparent display apparatus of claim 1, wherein the virtual object is displayed non-transparently so as not to penetrate the real object on the transparent display.

4. The transparent display apparatus of claim 1, wherein the controller estimates an area that the real object penetrates and shows on the transparent display with respect to the position of the user by utilizing the position of the user and the position of the real object, estimates an area in which the virtual object displays on the transparent display by utilizing the position of the user and the predetermined position of the virtual object, and estimates the overlapping area.

5. The transparent display apparatus of claim 1, wherein the second detector detects coordinate information of the user'"'"'s eyes as the position of the user.

6. The transparent display apparatus of claim 1, wherein the virtual object displayed on the transparent display is a three-dimensional (3D) virtual object.

7. A method of controlling a transparent display apparatus displaying a virtual object having a predetermined position on a virtual dimensional area, the method comprising:

detecting a position of a real object placed in a first direction from the transparent display, and a position of a user in a second direction from the transparent display;

estimating distances of the real object and the virtual object with respect to the position of the user and an overlapping area of the real object and the virtual object on the transparent display from the position of the user based on the detected position of the real object, the detected position of the user and the predetermined position of the virtual object;

determining as to whether or not to display the virtual object on the overlapping area based on the distances of the real object and the virtual object with respect to the position of the user; and

displaying the virtual object based on the determination results.

8. The method of claim 7, wherein the determining comprises determining to display the virtual object on the overlapping area, if the distance of the virtual object regarding the position of the user is closer than the distance of the real object regarding the position of the user, and determining not to display the virtual object on the overlapping area, if the distance of the virtual object regarding the position of the user is longer than the distance of the real object regarding the position of the user.

9. The method of controlling claim 7, wherein the virtual object is displayed non-transparently so as not to penetrate the real object on the transparent display.

10. The method of claim 7, wherein the estimating the overlapping area of the real object and the virtual object comprises:

estimating an area in which the real object penetrates and shows on the transparent display from the position of the user by utilizing the position of the user and the position of the real object;

estimating an area in which the virtual object displays on the transparent display by utilizing the position of the user and predetermined position of the virtual object; and

estimating the overlapping area based on the area in which the real object penetrates and the area the virtual object is to be displayed.

11. The method of claim 7, wherein the detecting the position of the user comprises detecting coordinate information of user'"'"'s eyes as the position of the user.

12. The method of claim 7, wherein the virtual object displayed on the transparent display is a three dimensional (3D) virtual object.

13. A transparent display apparatus, comprising:

a transparent display to display a virtual object;

a first detector to detect a position of a real object placed behind the transparent display;

a second detector to detects a position of a user in front of the transparent display; and

a controller to estimate an overlapping area of the real object and the virtual object on the transparent display with respect to the position of the user based on the detected position of the real object, the detected position of the user and a position of the virtual object.

14. The transparent display apparatus of claim 13, wherein the controller controls the transparent display to display the virtual object on the overlapping area based on the distances of the real object and the virtual object regarding the position of the user.

15. The transparent display apparatus of claim 14, wherein the controller displays the virtual object on the overlapping area, if the distance of the virtual object regarding the position of the user is closer than the distance of the real object regarding the position of the user, and does not display the virtual object on the overlapping area, if the distance of the virtual object regarding the position of the user is longer than the distance of the real object regarding the position of the user.

16. The transparent display apparatus of claim 13, wherein the second detector detects coordinate information of the user'"'"'s eyes as the position of the user.

17. The transparent display apparatus of claim 13, wherein the virtual object displayed on the transparent display is a three-dimensional (3D) virtual object.
