ITAC’s Evolution Mouse Trak™ is a six-button programmable trackball designed to eliminate complex motions required by a mouse. The hand support is curved and elevated to fit your palm and reduce wrist fatigue. The keys are positioned to fall under the thumb and fingers more easily, reducing movement. Additionally, the keys move inward when pressed providing a smaller, less tiring motion. The six buttons can be programmed for functions such as click, drag lock, double click and speed control. Unlike other pointing devices, the Evolution Mouse Trak requires no software for programming.
