Another fantastic innovation is the Light Touch pico projector. It is projector that can turn any surface into a virtual touch-screen computer which is introduced by the Light Blue Optics. The Light touch pico projector is a gadget that uses holographic laser-projection technology to beam a 10in virtual touch-screen on to any surface. The infrared sensors detect the finger taps of the user which allows them to type words, open or close programs and applications.
It runs Windows CE and users can use it to write a letter or watch a video.
"The opportunities for Light Touch extend beyond consumer electronics," said Chris Harris, chief executive of Light Blue Optics. "It could profoundly change the way people interact with multimedia content and the built environment."
This is totally different from any other projectors. What we used to think was impossible is being invented and introduced nowadays.
