Abstract
In a pen-input computer or the like, it is impossible to distinguish an input method and to execute a proper process according to the input method. A touch panel driver generates finger-input coordinate values for a display screen. A digitizer driver generates pen-input coordinate values for the display screen. A processor receives the coordinate values and additional information indicative of either the finger-input or the pen-input from a source discriminator, starts an inputting process according to the input method, and allows a virtual keyboard to be displayed onto the screen or allows a “CHR input pad” window to be opened.
