I was expecting different click-bait, like a keyboard drawn on paper with a camera pointed at it or something.

- Izkata 6y agoHow about a laser-projection bluetooth keyboard? https://www.youtube.com/watch?v=xmKdtAePxy8 https://www.youtube.com/watch?v=xmKdtAePxy8 They've been available for a few years now.
- gertlex 6y agoFun fact: they've been available for over a decade at this point. I wouldn't be surprised if it goes back a few years more than this 2008 article. Never personally used one, though. https://www.geeky-gadgets.com/geeky-gadgets-the-bluetooth-laser-virtual-keyboard/ https://www.geeky-gadgets.com/geeky-gadgets-the-bluetooth-la...
- freeone3000 6y agoAin't great. You can only type certain keys at a time since the beam-break for j prevents a follow-up n in the denounce period. I only get about 30wpm... Disregarding feedback.
- cgriswald 6y agoIt could probably be done now just by looking at hand shapes and if you’re a touch typist you might not even need the projection, just a dot or two (which could just be stickers on a surface) to orientate your hands over nothing.
- freeone3000 6y agoHand shapes for typing are far from standardized or recognisable. Nowhere near the accuracy a laser beam break gives you. (The projection LED is separate from the detection laser, which is much lower power)
- skc 6y agoMe too, and probably possible as hack that any decent developer can do right now. In fact when camera enabled glasses looked like they were going to be a thing that was the very thing I imagined taking off. You grab a piece of paper and haphazardly draw a bunch of keys on it and your glasses with a little AI do the rest
