Abstract
A pressure-sensing touch system for an electronic display includes a plurality of pressure sensors and a controller. Each pressure sensor of the plurality of pressure sensors is configured to generate a signal indicative of pressure applied to a surface of the electronic display. The controller is configured to (i) receive spatial coordinates of a plurality of touch events simultaneously occurring on the electronic display, (ii) select a subset of the plurality of pressure sensors, and (iii) calculate pressure values respectively corresponding to the plurality of touch events based on the spatial coordinates and the signals from the selected subset. The selected subset is a proper subset.
