Light Touch - Hologram Laser Projection

Light Touch™ is an interactive projector that instantly transforms any flat surface into a touch screen. It frees multimedia content from the confines of the small screen, allowing users to interact with that content just as they do on their hand held devices – using multi-touch technology.

Light Touch™ has Holographic Laser Projection (HLP™) technology inside which creates bright, high-quality video images in WVGA resolution. Integrated infrared sensors detect motion and turn the projected image into a 10.1″ virtual touch screen, so the user can control the projector and interact with applications simply by touching the image.

The hologram laser projection reminds me this optical device that used in the military, the good thing about laser is its brighness and transmition, the image can be projected much further and its less heat which is always a problem of a traditional projector. I guess the portable projecting screen era is comming soon.
