The L-Trac has selectable resolutions, allowing rapid changes of sensitivity. The high-performance laser navigation system is capable of tracking at high speed. This means the user can "fly" around the screen with a flick of the finger or snap from one side the screen to the other with a healthy flick of the arm. Either way, this precision, high-performance pointing device produces predictable, quick and precise motion that becomes intuitive in a few minutes of use.
