Abstract: The present disclosure includes systems and methods for touch sensing. An electronic device includes a resistive sheet that is optically transmissive, a number of electrodes electrically coupled to the resistive sheet, the electrodes disposed at an edge of the resistive sheet and spaced apart at predetermined intervals, and a processor coupled to the number of electrodes. The processor is configured to generate, at a first of the electrodes, a first drive signal, generate, at a second of the electrodes, a second drive signal, each drive signal having a different frequency, measure an output of at least one of the electrodes, and determine, based on the output, a location of a touch input on the resistive sheet.
