The American MirraViz company presents a display technology that allows multiple people to see completely different content at the same time on the same screen. Depending on the viewing angle monitor, one can play a video game while the adjacent track of a movie.

The multiple views feature works with at least two projectors that use reflective screen display, as used in road signs or bicycle reflectors. Retrospective reflection returns the light to its source, as the screen is able to receive several light sources. The viewer is at the same angle to the projector dedicated to him, and therefore sees only images raised.
