The SmartNav hands-free mouse by NaturalPoint enables the user to point and click by using slight movements of the head. Three different designs, with progressively sophisticated features, are available for differing needs: The SmartNav Standard Version is for individuals who want to increase their computer productivity, the Ergonomic version is for those who suffer from carpal tunnel or other forms of wrist strain, and the Assistive Technology version is designed for users who cannot use their hands (includes a virtual keyboard). SmartHomeUSA carries all three versions, and their website includes videos of the devices in use as well as a comparison chart of their features. Priced from $224 to $400.
