If using joysticks to play computer games is too much effort, then why not
simply nod at the screen? That鈥檚 the principle of UseYourHead, a new piece of
software developed by Cybernet Systems of Ann Arbor, Michigan. Using a webcam,
the software monitors the user鈥檚 head movements and translates them into actions
in the game鈥攖he more you move your head, the more your character moves on
screen. The hope is that the system will make game-playing more realistic as
characters move in response to the gamer鈥檚 armchair agility.
