Abstract
Plural position pointing devices are used with software which is not designed for plural position pointing devices. A coordinate input system works with a coordinate detecting device having a multi-device function, which enables the device to detect the coordinate value of and switch information on each of a plural position pointing devices even when they are present on a single coordinate detecting surface at the same time. A tablet driver receives the information sent from the coordinate detecting device to a computer and hands it over to an application program. Determinations are made as to whether the switch information on the plural position pointing devices indicates ON. If all the switch information indicates OFF, all the information on the plural position pointing devices is mixed and handed over to the application program. If any of the switch information indicates ON, the information on only the position pointing device having ON switch information is handed over to the application program.
