The laser keyboard projection is sort of an image of a real keyboard but which does not really exist physically. Most systems may be used as a virtual mouse or virtual piano.
This is how these devices work: the visible virtual keyboard is projected onto the surface by a laser or with some systems, by a beamer. The projecting device is equipped with a sensor or sensorial camera that picks up the finger movements and touches and when these are detected, they are transformed into actions or characters.
Some systems use an invisible infrared as a second beam to create a wireless laser keyboard projection. This type of product projects an invisible infrared beam above the virtual keyboard on which one uses the fingers to make keystrokes on the projected keyboard. The beam is equipped with sensors and cameras that translate the place when the infrared light was broken into characters or actions.
