ABSTRACT:
The subject application relates to a system(s) and/or methodology that facilitate vision-based projection of any image (still or moving) onto any surface. In particular, a front-projected computer vision-based interactive surface system is provided which uses a new commercially available projection technology to obtain a compact, self-contained form factor. The subject configuration addresses installation, calibration, and portability issues that are primary concerns in most vision-based table systems. The subject application also relates to determining whether an object is touching or hovering over an interactive surface based on an analysis of a shadow image.
