SmartNav 4 - How Stephen Hawking Became the Quakemaster

SmartNav has updated its accessibility product to level 4. Their AT and EG models are designed to help the physically challenged and RSI affected improve their lives (and apparently their frag count). The SmartNav 4 uses an infrared camera and a small reflective dot placed on the users head or cap to track motion and translate it into mouse movements, basically the same technology used in the Wii-mote controller system. The AT (Assistive Technology) model is designed for enabling computer interaction completely without the aid of arms for handicapped and injured users. The EG (Ergonomic) model is made to work alongside other input forms as well as head tracking. This latest model has 4x the resolution of the previous model 3 and has 25% wider range of coverage and distance. The Ergonomic model can be ordered in their online shop for $399 and the Assistive version for $499.
