As I understand it, this keyboard projects the keys on a flat surface with a laser, then uses a light detector (filtered so that it only really sees the light from the laser itself), which looks for holes in the pattern of reflected laser light. I'd like to see what happens if you put your hand in front of the laser, blocked out more than one key at a time, or tried to project on a surface with a real hole, or glass panel, etc. "Touch" typing would probably be difficult, as you'd have to be careful about which "keys" you're "pressing" at every moment. >Anyway, it sounds novel and interesting.
