Tilt Five

Tilt Five is an gaming platform that uses head mounted optical see through displays and 3D tracking to overlay images onto a game board.

It has been called an "augmented reality" gaming platform.

It can work with multiple users who each wear headsets and view a shared game board.

The gadget operates on the principle of retroreflectivity: 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 same user'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 gadget that can also be used like a normal game controller in some games.
