Abstract

An apparatus includes a state-switchable screen, a video camera, and a video projector. The video camera and projector are located on a side of the screen opposite to the side thereof of a video conference participant. The apparatus is configured to temporally interleave the screen between a substantially transparent state and a diffusive state. In the substantially transparent state, the video projector is configured to be outside of a viewing field of a video conference participant looking toward the video camera.
