Hi guys,
I've recently bought a laser keyboard (see attachment) and, apart from the fact that it appears to have an intermittent fault, when it is working I am extremely impressed with it.
I've been wondering how this works and I thought maybe one of you lot could offer a suggestion. How does the laser "paint" the image of the keyboard out? I'm assuming it must scan somehow and switch on/off at the right times to paint the graphics out. I can't see any moving mirrors that would create the scan though...
It's also quite impressive how it senses when your finger hits a key. I'm guessing it does this based on how far off the ground the laser projector is, and therefore it knows where the graphics will be displayed. It would probably only work when it is sat at a 90 degree angle to the desk. It really is very impressive though!
