Touch screen emulates mouse

摘要

An information input system for a host computer 16 comprises an absolute position pointing device 11 e.g. a touch screen first translation means 14 to receive and translate a signal from the absolute position pointing device 11 and provide an output to a second translation means 15 which is adapted to receive and translate signals from a relative position pointing device e.g. a mouse, the second translation means 15 in use, translating the output from the first translation means 14 and providing an input for further processing by the host computer 16. This arrangement allows mouse emulation using a touch screen.
