Ablenet 12060100 TrackerPro
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).
It is a high-resolution intelligent camera in a solid aluminum enclosure, making it smooth, reliable, stand-alone, robust, accurate and easy to mount.
TrackerPro tracks a small dot that you can place on your forehead, glasses or the rim of a hat.
Tracker is not a toy meant for the gaming market and then sold to people with disabilities as a secondary thought; it is dedicated assistive technology designed exclusively for people with limited use of their hands.
