Abstract

An electronic apparatus and a method for processing an input signal are provided. In the present invention, a signal conversion module is provided, and the signal conversion module registers into an operating system. A raw data corresponding to an input signal is obtained from the operating system through the signal conversion module, when the input signal is received from a human interface device. And a reference value is obtained from a driver of the human interface device through the signal conversion module. The raw data is converted into a coordinate data according to the reference value through the signal conversion module, and the coordinate data is sent to an application program through the signal conversion module.
