INFRARED KEYBOARD

This is an optical virtual keyboard . the infrared keyboard is a compact and versatile product. The size of a virtual infrared keyboard is like the size of a cell phone. It optically detects and analyses human hand and finger motion . It works with wireless bluetooth technology.The light is invisible to the user and hovers a few millimeters above the surface.

Of course, like any magic trick there's actually something very specific happening behind the scenes that creates the illusion. When your finger passes through a key's projected area, the sensor detects the infrared light reflecting off of it and compute it as a keystroke.It can even serve as a mouse or touchpad for your windows PC or Mac.
