Holographic Keypads Float Into View
prostoalex writes "The New York Times tells the story of a Connecticut-based company called HoloTouch that is developing input devices that literally "float in the air". The technology will be licensed for information kiosks in New York city. Some other sample applications are available from the company's Web site. HoloTouch already managed to secure the patent on its technology."
But have they really been able to build one, or are they just patenting the idea with hopes someone else will and they they can sue and get rich? I see nothing on their website (other than very obviously mocked up fake pictures) or in the patent that says they really know how to do this.
I'm an American. I love this country and the freedoms that we used to have.
Okay, just assuming that this is a case in which they haven't invented anything, and it is actually a good idea [neither of which I feel able to judge], here is a workaround, NOW PUBLIC DOMAIN!
Instead of making holographic keypads, make use of the double-parabolic-mirror optical illusion. You know the kind, shown in Edmund Scientific, where there are floating coins in the air. That is clearly not a hologram, but it would work just as well.
If you feel at all inclined to make something, bookmark this reply!
