Projected capacitive to surface capacitive interface

Abstract

A projected capacitive to surface capacitive interface comprises a projected capacitive touch controller connected to a projected capacitive touch sensor either with a chip on flex circuit or with a discrete chip on board controller, a connector wire, which coordinates the interface between the projected capacitive touch controller and an emulation board, a surface capacitive touch controller and a connector connecting the surface capacitive touch controller to a host computer. The interface communicates with the microcontroller that converts a calculated touch position to resistance values that are then sent to the surface capacitive touch controller as if the resistance values were measured values at four corners of a touch screen. The surface capacitive controller then is able to recalculate the calculated touch position using these resistance values and sends/reports a final touch position to the host computer.
