ABSTRACT:
A data processing device includes an emulation processing section for performing prescribed processing on an output signal of an operation pad for conversion into a signal or data which is equivalent to a signal or data that would be obtained when operating a mouse to generate information. The operation pad is then usable with an application program that is designed for use only with signals output from the mouse.
