Operating without wires using Bluetooth, this keyboard will project a fully operational Class II laser-generated keyboard onto any flat, opaque surface.
The keyboard itself is 9 3/4″-wide x 4″-deep with 3/4″ keys once projected and promises to recognize “keystrokes in three dimensions by an optical sensor that detects finger placement at different areas on the keyboard, distinguishing between a finger hovering above the space bar or a number key.”
Keyboard functionality is enhanced by “an invisible infrared horizontal plane projected millimeters above the surface detects actual contact with “keys”-when the plane is interrupted by a finger, the projector assigns a keyboard character, passing it along to a paired device.”

Worried this keyboard won’t be able to keep up with your amazing touch-typing? As long as you don’t exceed about 400 characters per minute you should be safe.
