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 touchscreen device is preferably positioned in front of or displaced laterally, above, below, or to the side of the screen of the display monitor used with the computer. 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. The high resolution available with an expansive touchscreen is enjoyed, without sacrificing desk or table space.
