Claim One:
1. A computer-implemented method for detecting a gesture performed by a user in connection with a user interface comprising a plurality of sensor blobs, the method being performed in a computerized system comprising a central processing unit, a projector, a camera and a memory, the computer-implemented method comprising: a. using the projector to project a content and a plurality of identical non-contiguous dot-shaped sensor blobs on a display surface; b. acquiring a plurality of images of the plurality of identical non-contiguous dot-shaped sensor blobs projected on the display surface using the camera; c. using the central processing unit to identify occlusion of at least some of the plurality of non-contiguous dot-shaped sensor blobs projected on the display surface by the user in the acquired plurality of images of the plurality of non-contiguous dot-shaped sensor blobs; and d. using the central processing unit to detect the gesture performed by the user based on the identified occlusion of at least some of the plurality of non-contiguous dot-shaped sensor blobs in the acquired plurality of images.
