**HeadMouse Extreme**

HeadMouse Extreme replaces the standard computer mouse for people who cannot use or have limited use of their hands when controlling a computer or augmentative communication device. The HeadMouse captures the movements of a user's head then translates it directly into proportional movements of the computer mouse pointer. This device works just like a computer mouse, with the mouse pointer being moved by the motion of the users head. This device cost around \$1000 [6].
