That looks ike a pretty good idea for bars or restaurants, nothing really to spill food or drink on. Could be some cool wireless thin-clients. Looks like this was showcased at CES 2010.

Also check out their Light Speed, a pretty cool product for cars: http://lightblueoptics.com/products/light-speed/ http://lightblueoptics.com/products/light-speed/

I know they're only computer generated graphics, but maybe it's a bit miss-leading as to how it will actually look. Particularly like this http://thesupergoodlife.com/2011/09/08/light-touch-projector/lt2_480x276/ http://thesupergoodlife.com/2011/09/08/light-touch-projector... Assuming the projector is mounted in the shelf, there would be quite a large shadow under where she is touching the wall. I guess the implications of this on such a small screen would be you'd have to pretty much figure out what you were going to press before you put your hand in front of the beam. We have Promethean IWB's and short throw projectors at school, trying to use them with your finger for precise menu operations is a nightmare. I think there used to be a keyboard that did something similar but it had terrible reviews

  Like this one? It looks pretty lousy. http://www.virtual-laser-devices.com/ http://www.virtual-laser-devices.com/

    Yeah like that, I really wanted one till I read the reviews. If they could do it properly (I.E. make it bright and accurate) it has the potential to be really cool but maybe keep it on the drawing board for a few more years.

It's a laser projector combined with a camera. Nice but nothing revolutionary. You can build something like this yourself using e.g. a Microvision ShowWX+ ($300), a webcam and some mirrors. No need to wait for a device that might be commercially available sometime in the future at an unknown price point.

  It actually is quite interesting, since it is a 2d holographic laser projector.

    I agree that the technology behind it [1] is quite interesting. However, the linked article talks about a specific application which I find not that novel. [1] http://lightblueoptics.com/technology/holographic-laser-projection/ http://lightblueoptics.com/technology/holographic-laser-proj...
