Tilt Five

Tilt Five is an augmented reality gaming platform developed principally by Jeri Ellsworth. It allows multiple users to don headsets and view a shared game board. The device operates on the principle of retroreflective images: The headsets send out light which bounces off the game board at the same angle that it was received at, which then goes right into the user's eyes. Because each player has a different viewpoint, the light from each headset only bounces into the right person's eyes.

Tilt Five has been marketed as a gaming platform, but it is stunted due to its requirement of a PC or android phone to use.

Tilt Five's input is a wand-like device which appears to be magic. However, it is not. The wand device has buttons that can be used like a normal game controller in some games.
