How It Works

The projection laser displays the keyboard layout, measuring approx. 241 x 106 mm, onto any opaque flat surface. Keystrokes are recognized and then relayed via an invisible infrared layer combined with an optical sensor.

The recognition process works as follows: When the user presses a key on the projected keyboard, the infrared layer is interrupted. This produces UV reflections that are recognized by the sensor in three dimensions, allowing the system to assign a coordinate (keyboard character).
