vehicle, you can give commands with your foot. The interfaces are simple to design to
give a simple progressive order.
A more original idea has been developed to give commands with the user's head
in front of a screen.
Webcams, which have become common on PCs, are used by the programs to
give a command via the head. In image processing, the computer detects the lateral
movements (horizontal and vertical) of the head. These commands are used, for exam-
ple, to move the point of view of the scene of the video game. Though it is certainly
recreational, a certain level of fatigue is bound to appear after some time.
