US 2021/0240293 A1 · SCREEN-TO-SCREEN COMMUNICATION VIA TOUCH SENSE ELEMENTS

Abstract

A method includes a first computing device generating a signal having an oscillating component and driving the signal on a first touch sense element of the first computing device. The method continues with the first computing device detecting a touch on the first touch sense element based on the signal. While the touch is detected, the method continues by the first computing device modulating the signal with data to produce a modulated data signal. The method continues with a second computing device receiving the modulated data signal via a transmission medium and a second touch sense element of the second computing device, where the transmission medium includes at least one of a human body and a close proximity between the first and second computing devices. The method continues with by the second computing device demodulating the modulated data signal to recover the data.
