The present invention describes 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 can be observed by viewing the second surface; 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 the light received by the camera but substantially blocks the light produced by the first projector, wherein the first filter is a GMR (Guided Mode Resonance) filter.
