How it work?
This Product emits infrared light from lower end of the product to detect objects such as fingers. When an object passes through the area illuminated by the infrared light ources,any infrared light reflecting off the object is detected by the sensor. Information on the position and movement of the object is then analyzed to perform the product’s role as a keyboard
Technology:
The projection laser displays the keyboard layout onto any opaque surface, Keystrokes are recognized and relayed Via and invisible infrared layer combined with an optical sensor. The Recognition process works as follows: when the user Presses a key on the projected keyboard, the infrared layer is interrupted .this produces IR reflections that are recognized by the sensor in three dimensions, allowing the system to assign a coordinate(keyboard character).
