Light Touch, a projected touch screen

At CES 2010, Light Blue Optics has released the Light Touch, a projected touch screen that let the user transform a flat surface (like table) into a screen on which he may scroll and click:

The virtual keyboard that we see on this video seems to be quite easily usable, although this device introduces a noticeable delay. This device uses HLP (Holographic Laser Projection), as explained in the fourth video of the sequence above.

Unlike other devices like Celluon evoMouse or Leap Motion (on which I will soon publish more information!), this projector combines both display and touch for screen, keyboard and mouse replacement. Awesome!

Unfortunately, this device still seems unsold 🙁
