The angle of the reflected laser light off the finger determines the position (hence the “which key”) context. The required components including a laser and two miniature CCD cameras, can easily and inexpensively be assembled in a small pocket device the size of a cigar.
In addition, the entire “keyboard position” is defined not only by the original projected location, but also by watching the drift of the typists fingers, thus not requiring the user to return exactly to the previous home position.
