AirType

The video describing the project looks interesting :

Reminds me of the phantom keyboard in "Rainbows End"! Many years back there were these laser keyboards that would project an image of keys on a surface that you'd type with. Heard the lack of mechanical feedback made them a challenge to use.

I get that they're reaching for the Minority Report-esque solution but I can't ever see these things selling to a market past early adopters and/or people who hate keyboards with extreme fury. The latter market being far smaller than the former.

mmmm. staying hungry for more. the video does not explain how the experience of knowing what and how you are typing works and how accurate it is.
