Abstract
A personal computer system enables simultaneous use of a relative-coordinate-mode input device and an absolute-coordinate-mode input device, thereby allowing correct input of absolute coordinate data, such as for characters. A pad-type first input device and a stick-type second input device are provided for a notebook computer. The first input device outputs both absolute coordinate data and relative coordinate data. The second input device outputs only relative coordinate data. When the absolute coordinate data is output, the relative coordinate data format is converted into the same format as the absolute coordinate data, and ID information for distinguishing the relative coordinate data from the absolute coordinate data is added to part of the relative coordinate data format.
