Patent ID: 8488042

Claim:
A visual-collaborative system comprising: a display screen having a first surface and a second surface; a first projector positioned to project images onto a projection surface of the display screen, wherein the projected images are observable by viewing the second surface, and wherein the projected images are transmitted onto the projection surface at a first set of wavelengths of a first color and a first set of wavelengths of a second color; and a first camera system positioned to capture images of objects through the display screen, the first camera system including a first filter disposed between a first camera and the first surface, wherein the first filter passes light at a second set of wavelengths of the first color and a second set of wavelengths of the second color received by the camera but substantially blocks the projected images transmitted onto the projection surface at the first set of wavelengths of the first color and the first set of wavelengths of the second color by the first projector, wherein the first and the second sets of wavelengths of the first color are substantially non-overlapping, and wherein the first and the second sets of wavelengths of the second color are substantially non-overlapping.
