Holographic laser projection

Light Blue Optics presented a revolutionary device nominated in two categories at once (the best portable media player and the best personal electronic device) at the CES 2010 consumer electronics show.
The device can turn any flat surface into a 10-inch touchscreen.
UPD: thanks to georgek now there is a link to the video with the device in operation.

Like this: a small turret, which you can put on the table and enjoy the picture.
Want to show photos to your friends: just sit down at a table in a cafe, remove the device and ...


Built-in infrared sensor allows you to control the image and drive information.

You can, of course, not only project an image onto a horizontal surface.


However, you will say, what is the innovation: the projection interactive screens have long been used, in many shopping centers you can kick a virtual projected ball on the floor.

It's all about the technology of creating a projection. In this case, the authors used what they called a holographic laser projection: lasers of primary colors irradiate a special micro-screen that serves as a diffraction grating. As a result, the image is much brighter and clearer than when using conventional projection technology.

They have another project that I’ve been waiting in my car for two years already ...
