Assentive Computer Technology - Infrared Head Pointing

The Tracker and the Smart Nav AT can be helpful for users with carpal-tunnel syndrome, severe arthritis, quadriplegia, ALS, muscular dystrophy, and multiple sclerosis. Head pointing should be considered for computer users who have good head control and poor (or no) fine motor skills in their hands. Pointing is the quickest, most direct way of controlling the computer. Many people with disabilities have been forced to use scanning, mouth sticks, and other alternative devices when all they really needed to do was somehow point. One 'point' to remember when considering this kind of alternative mouse: you can use your head, but you don't really have to.
