...no I haven't but that looks awesome. I wonder how well they'd work for gaming.

I've hear of them but it seems like they would be awkward to use. There is no tactile sensation that you get with the return of keys on a real keyboard to you don't know if you hit a key correctly until you see it on the screen.

I also wonder how they work. I'm assuming it knows when a shadow is cast over a certain key then you have pressed it. Seems like it could be a little buggy.

It would be a fun novelty item to use but not for $150

I've seen these for some time..... interesting but a gimmick.

I've been interested in these for a long time. I don't think they would register fast enough for gaming. but word processing and web browsing would probably be good.
I was doing some research on them and found out how they work. There is 2 LEDs inside. 1 red to project the keyboard and 1 IR that works almost like radar being it can tell how far away your fingers are passing through the beam and tell the internal hardware what key is being "pressed". I could be wrong in that but i could swear that how it worked.

..so waving your hands through the laser would make for some gibberish words?

I'm thinking that would only work if you ran your hand along whatever surface you've got the keyboard projected onto.

What if you sneezed in the path? All that snot hitting the desktop would have to type something....

Just another reason why they need more satan at high-tech companies.
