Dual pointing device used to control a cursor having absolute and relative pointing devices
First Claim
1. A personal computer system comprising:
- a plurality of different types of coordinate input devices;
a keyboard input device;
an output device for outputting a signal from each of said coordinate input devices; and
a processing unit for performing processing based on signals from said output device in accordance with an operation of each of said coordinate input devices, wherein a single output port of said output device is shared by said coordinate input devices.

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.

2. A personal computer system comprising:
-
a first input device;
a second input device, said second input device performing a detecting operation in a manner differing from said first input device;
a keyboard input device; and
an output device for converting one of an output signal from said first input device and an output signal from said second input device, or for converting both the output signals from said first input device and from said second input device and outputting the resulting signals in an identical format, whereby said first input device and said second input device are alternately or simultaneously used. - View Dependent Claims (3, 4)
