Signal conditioning on touch-enabled devices using 3D touch

摘要

The various implementations described herein include methods, devices, and systems for detecting touch inputs. In one aspect, a device includes: (1) a touch surface; (2) a plurality of sense electrodes coupled to the touch surface and configured to sense capacitance of a touch input; (3) one or more force electrodes coupled to the touch surface and configured to sense force of the touch input; and (4) a sensing module configured to: (a) determine capacitance of at least a subset of the plurality of sense electrodes; (b) determine force of at least one of the one or more force electrodes; and (c) if the capacitance meets one or more first predefined criteria indicative of a touch input and if force meets one or more second predefined criteria indicative of a touch input, determine that the touch input is present on the touch-sensitive surface.
