System and method for detecting and characterizing touch inputs at a human-computer interface

One variation of a system for detecting inputs at a computing device includes: a substrate including a top layer, a bottom layer defining an array of support locations, and electrode pairs proximal the support locations; a touch sensor surface arranged over the top layer of the substrate; a set of s...

description One variation of a system for detecting inputs at a computing device includes: a substrate including a top layer, a bottom layer defining an array of support locations, and electrode pairs proximal the support locations; a touch sensor surface arranged over the top layer of the substrate; a set of spacers, each arranged over an electrode pair at a support location on the bottom layer of the substrate and including a force-sensitive material exhibiting variations in local bulk resistance responsive to variations in applied force; an array of spring elements coupled to the set of spacers, configured to support the substrate on a chassis, and configured to yield to displacement of the substrate downward toward the chassis responsive to forces applied to the touch sensor surface; and a controller configured to interpret forces of inputs on the touch sensor surface based on resistance values of the electrode pairs.
