Abstract
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 configured to sense capacitance of a touch input; (3) one or more force electrodes configured to sense force of the touch input; and (4) a sensing module configured to: (a) determine a first capacitance; (b) determine whether the first capacitance exceeds an adaptive threshold; (c) if the first capacitance does not exceed the adaptive threshold, determine a force; (d) if the force meets one or more predefined criteria indicative of a touch input, lower the adaptive threshold; (e) determine a second capacitance; (f) determine whether the second capacitance exceeds the lowered threshold; and (g) if the second capacitance exceeds the lowered threshold, determine that the touch input is present on the touch surface.
