How it works:


When you type on a virtual laser keyboard, there aren't any switches involved. In fact, there aren't any mechanical moving parts at all. The device projects the image of a QWERTY keyboard onto a flat,non-reflective surface using a red diode laser. The laser, similar to the kind you see on those cheap laser pointers people wave at rock concerts, shines through a Diffractive Optical Element (DOE), which is simply a tiny image of the keyboard. The DOE, along with special optical lenses, expands the image to a usable size and projects it onto a surface.


But a simple image of a keyboard won't get you anywhere -- something needs to analyze the information you type in. Situated near the bottom of the device is an infrared (IR) laser diode, which shoots out a thin plane of infrared light. The plane, which is invisible and runs parallel to the surface, rests only millimeters above the image of the keyboard. When you start typing, you pass your fingers through certain areas of the infrared light. A CMOS (complimentary metal-oxide semiconductor) images your finger's position within the area of the keyboard, and a special sensor chip called a Virtual Interface Processing Core analyzes the location of the intended keystroke. The device then sends this information to the computer receiving the commands.


If it sounds like a gadget from the future, a virtual laser keyboard sort of looks like one, too,especially when it's on full working display. They're small and sleek, weigh about two ounces (56.7 grams) and comparable in size to a pack of gum, so they can fit easily into pockets or carrying bags.
