The Invisible Keyboard
It will perhaps become possible in the near future to type on an invisible keyboard, without touching a direct surface.
The company Syntellia, that aims at keyboard technologies, has released a short video in which a man is seen that is typing in front a webcam or eye, while not actually touching anything. On the big screen than appear the words the man is supposedly typing. It would be a collaboration between Fleksy and Leap Motion.
The Leap Motion Controller is a small box that can be attached to every PC and can be equipped with a motion sensetive camera. The technique would be precise enough to differentiate finger movements. How the device knows where the location of the keyboard is in open space en how the user must know that isn’t known.
No release dates for the invisible keyboard have been made clear.
