Thread: Bright mobile touchscreen projector, others

This is very cool. Supposedly it works on any flat surface.





I like the idea, specially the touch screen part. 10 inch sounds like a good size. More:

The Light Touch casts a big image from up close by bouncing lasers off a 0.4-inch microdisplay, using techniques from holography to keep the picture in focus despite the sharp projection angle. Then it covers the image in a horizontal plane of infrared light that lies just above the table. An infrared camera watches for spots where a finger (or similarly sized object) breaks the plane and scatters the light.The machine figures out and executes the action corresponding to that location. It detects fast moves like swipes; an upgrade will sense multiple taps at once.
