Abstract

An interactive video display system allows a physical object to interact with a virtual object. A light source delivers a pattern of invisible light to a three-dimensional space occupied by the physical object. A camera detects invisible light scattered by the physical object. A computer system analyzes information generated by the camera, maps the position of the physical object in the three-dimensional space, and generates a responsive image that includes the virtual object. A display presents the responsive image.

Claims

1. An interactive video display system, comprising:

a light source configured to deliver a pattern of invisible light to a physical object occupying a three-dimensional space;

a camera configured to image the three-dimensional space and detect invisible light scattered by the physical object;

a computing device configured to;

analyze information generated by the camera in response to the detection of the invisible light scattered by the physical object,

map the position of the physical object within the three-dimensional space based on the analyzed information, and

generate a responsive image based on the mapped position of the physical object, the responsive image including a virtual object, the virtual object being responsive to an interaction with the physical object; and

a display configured to present the responsive image.

2. The interactive video display system of claim 1, wherein the camera is a stereo camera.

3. The interactive video display system of claim 1, wherein the analyzed information corresponds to a hand of a user.

4. The interactive video display system of claim 1, wherein the virtual object represents a body of a user.

5. The interactive video display system of claim 1, wherein the virtual object represents a hand of a user.

6. The interactive video display system of claim 1, wherein the pattern of invisible light is infrared.

7. The interactive video display system of claim 1, wherein the responsive image is presented in real-time.

8. The interactive video display system of claim 1, wherein the computing device is further configured to send and receive data via a network, the data including the responsive image.

9. The interactive video display system of claim 1, wherein the light source and the camera are attached to the display.

10. The interactive video display system of claim 1, wherein the three-dimensional space is partitioned into a plurality of zones and different types of user interactions occur in each of the plurality of zones.

11. A method for providing an interactive display system, the method comprising:

delivering a pattern of invisible light to a physical object occupying a three-dimensional space;

detecting the invisible light scattered by the physical object, wherein the detection of the invisible light scattered by the physical object occurs at a camera imaging the three-dimensional space;

analyzing the information generated by the camera in response to the detection of the invisible light scattered by the physical object;

mapping the position of the physical object within the three-dimensional space based on the analyzed information;

generating a responsive image based on the mapped position of the physical object, the responsive image including a virtual object, the virtual object being responsive to an interaction with the physical object; and

presenting the responsive image.

12. The method of claim 11, wherein the camera is a stereo camera.

13. The method of claim 11, wherein the analyzed information corresponds to a hand of a user.

14. The method of claim 11, wherein the virtual object represents a body of a user.

15. The method of claim 11, wherein the virtual object represents a hand of a user.

16. The method of claim 11, wherein the pattern of invisible light is infrared.

17. The method of claim 11, wherein the responsive image is presented in real-time.

18. The method of claim 11, further comprising sending and receiving data via a network, the data including the responsive image.

19. The method of claim 11, wherein the delivering and the detecting occur above the presented responsive image.

20. The method of claim 11, wherein the three-dimensional space is partitioned into a plurality of zones and different types of user interactions occur in each of the plurality of zones.
