Abstract

Disclosed are a method and an apparatus for providing the touch information of a 3-D object. The method includes creating a hexahedral bounding box around the 3-D object, acquiring a depth information image for each side of the hexahedral bounding box, creating six touch attribute images corresponding to six depth information images, and providing a touch attribute of at least one of the six touch attribute images to a user.

Claims

1. A method for providing touch information of a 3-D object, the method comprising:

creating a hexahedral bounding box around the 3-D object;

acquiring a depth information image for each side of the hexahedral bounding box;

creating six touch attribute images corresponding to six depth information images; and

providing a touch attribute of at least one of the six touch attribute images to a user.

2. The method of claim 1, wherein the providing of the touch attribute to the user comprises providing a plurality of touch attributes by providing plural sets of touch attribute images.

3. The method of claim 1, further comprising setting resolution of the six touch attribute images equal to resolution of the depth information images.

4. The method of claim 1, wherein the creating of the six touch attribute images comprises recording a touch attribute in a position where a pointer, which is marked in one point of the 3-D object, is represented in the touch attribute images.

5. The method of claim 4, wherein the creating of the six touch attribute images further comprises selecting at least single touch attribute image from the six touch attribute images by using the depth information images.

6. The method of claim 1, wherein each depth information image is acquired by a virtual camera located at each side of the bounding box.

7. The method of claim 1, further comprising sensing contact of a user making contact with at least one point on a surface of the 3-D object.

8. An apparatus for providing touch information of a 3-D object, the apparatus comprising:

a bounding box generator for creating a hexahedral bounding box around the 3-D object;

a depth information acquiring module for acquiring a depth information image for each side of the hexahedral bounding box;

a touch attribute generator for creating six touch attribute images corresponding to the six depth information images; and

a haptic device for providing a touch attribute of at least one of the six touch attribute images to a user.

9. The apparatus of claim 8, wherein the haptic device provides a plurality of touch attributes by using plural sets of touch attribute images.

10. The apparatus of claim 8, wherein the touch attribute generator sets resolution of the six touch attribute images equal to resolution of the depth information images.

11. The apparatus of claim 8, wherein the touch attribute generator records a touch attribute in a position where a pointer, which is marked in one point of the 3-D object, is represented in the touch attribute images.

12. The apparatus of claim 11, further comprising a touch attribute selector for selecting at least single touch attribute image from the six touch attribute images by using the depth information images.

13. The apparatus of claim 8, wherein each depth information image is acquired by a virtual camera located at each side of the bounding box.

14. The apparatus of claim 8, further comprising a sensor for sensing contact of a user making contact with at least one point on a surface of the 3-D object.
