Abstract

A system capable of detecting changes within an environment in which a known image is displayed. The system includes a computing platform executing a software application being configured for comparing at least a portion of an image captured from the environment to at least a portion of the known image to thereby detect changes in the environment.

Claims

1. A method of translating a change to an environment into input data, the method comprising:

(a) displaying a first image on a surface present within the environment;

(b) capturing a second image of at least said surface present within the environment;

(c) computationally comparing at least a portion of said second image to said at least a portion of said first image in order to detect presence of a subject within the environment;

(d) tracking said subject or a portion thereof and identifying interaction between said subject and a content displayed in said first image;

(e) modifying said first image according to said interaction to thereby generate a modified first image; and

.

(f) displaying said modified first image on said surface.

2. The method of claim 1, wherein said surface is on a floor and further wherein said interaction results from said subject walking on said surface.

3. The method of claim 1, wherein said modified first image does not include said subject.

4. The method of claim 1, wherein said first image is an advertising banner.

5. The method of claim 1, wherein said first image is a dynamic image.

6. The method of claim 1, wherein said modifying said first image is at a region in which said interaction with said subject is detected.

7. The method of claim 1, wherein step (d) further comprises characterizing a shape of said subject or a portion thereof.

8. The method of claim 1, wherein step (c) is effected by a silhouetting algorithm.

9. The method of claim 1, wherein step (c) discounts shadowing caused by said subject.

10. The method of claim 1, further comprising adjusting a color value of pixels of said second image prior to step (c).

11. The method of claim 1, wherein said first image is a video image.

12. The method of claim 1, wherein said first image is a projected image.

13. The method of claim 1, wherein (e) is effected in realtime.

14. The method of claim 1, further comprising setting said modified first image as a new first image and repeating steps (a)-(f).
