Abstract
A pen mouse with an inclining compensation function includes an optical sensor, a sensor array, a pen tip and a processor. The optical sensor is adapted to sense a relative movement of an object. The sensor array has a plurality of sensing units. The pen tip is connected to the sensor array and adapted to activate at least one of the plurality of sensing units when being pressed by the object. The processor is electrically connected with the sensor array. The processor is adapted to compute a trace of the pen mouse via analysis of the relative movement and further to compensate the trace via analysis of the activated sensing unit.

A pen mouse with an inclining compensation function, comprising:
- an optical sensor adapted to sense a relative movement of an object;
- a sensor array having a plurality of sensing units;
- a pen tip connected to the sensor array and adapted to activate at least one of the plurality of sensing units when being pressed by the object;
- and
- a processor electrically connected with the sensor array, the processor being adapted to compute a trace of the pen mouse via analysis of the relative movement and further to compare a pre-stored quantity change and a pre-stored position change with a current quantity change and a current position change to identify whether a user of the pen mouse is authorized.
