The RollerMouse Free from Contour is an ergonomic alternative to a traditional desktop mouse. The device, which doubles as a wrist-rest for typing, features an innovative roller system for pointing. Rolling the bar up and down moves the cursor vertically, sliding the bar left and right moves it horizontally.
The device also features a standard scroll wheel, and 5 buttons, arranged in a symmetrical layout. The RollerMouse connects via USB, and is compatible with both Windows and Mac systems.
