Abstract
An electronic mouse simulator for a computer having a dedicated mouse port connector receptacle, the simulator having a multi-conductor cable and connector adapted to plug directly into the dedicated mouse port connector receptacle. The simulator includes a touchscreen device and a converter having an EPROM and program firmware therefor. The converter accepts signals from the touchscreen device and transforms them into a mouse-compatible format or mouse-compatible protocol that can be used to directly communicate through the dedicated mouse port of the computer. No modification of the computer is required; nor is special software needed, since the signals transferred at the mouse port duplicate those which would normally be transferred with a conventional mouse. In one embodiment, there is enabled an absolute mode of cursor control via the touchscreen device, with the sole electrical connection between the computer and the interface being via the computer's dedicated mouse port connector receptacle.
