An example system includes a pressure-sensitive sheet that extends along a first axis. The pressure-sensitive sheet includes a top surface and a bottom surface. A vertical force applied at a location along at least one of the top surface or the bottom surface forms an electrical path between the top surface and the bottom surface having a resistance, rf, that is inversely proportional to an amplitude of the vertical force. The system further includes read out circuitry configured to provide information indicative of the amplitude of the vertical force and the location of the vertical force along the first axis of the pressure-sensitive sheet.
