Tracker Pro: A mouse for people with little or no hand movement
TrackerPro is a computer input device that takes the place of a mouse for people with little or no hand movement. Simply plug it in and it works just like a mouse (no additional software required). Anything that can be done with a regular hand mouse can be done by using TrackerPro (in conjunction with one of many clicking solutions).
