One variation of a method for detecting an input at a touch sensor&#x2014;including a force-sensitive layer exhibiting variations in local resistance responsive to local variations in applied force on a touch sensor surface and a set of drive and sense electrodes&#x2014;includes: driving a drive electrode with a drive signal; reading a sense signal from a sense electrode; detecting a alternating-current component and a direct-current component of the sense signal; in response to a magnitude of the direct-current component of the sense signal falling below a threshold magnitude, detecting an input on the touch sensor surface during the scan cycle based on the alternating-current component of the sense signal; and, in response to the magnitude of the direct-current component of the sense signal exceeding the threshold magnitude, detecting the input on the touch sensor surface during the scan cycle based on the direct-current component of the sense signal.
