Abstract
A pen mouse with a tracing compensation function includes an optical navigation module, an angle detector and a processor. The optical navigation module is adapted to generate coordinates of the pen mouse. The angle detector is adapted to detect an inclination angle of the pen mouse. The processor is electrically connected to the optical navigation module and the angle detector, and adapted to transform the inclination angle into a compensation parameter and further to compute a trace of the pen mouse via computation of the coordinates by the compensation parameter.
