Abstract: One variation of a system for a touch sensor includes: a substrate; a cover layer; a spacer element; a second electrode; and a controller. The substrate includes: a support location arranged on the substrate; and a first electrode arranged proximal the support location. The cover layer defines a touch sensor surface arranged over the substrate. The spacer element: is coupled to the substrate at the support location; and yields to displacement of the substrate downward responsive to forces applied to the touch sensor surface. The second electrode: is arranged opposite the first electrode to define a nominal gap; and is configured to effect electrical values of the first electrode responsive to displacement of the substrate. The controller is configured to: read a set of electrical values from the first sense electrode; and interpret a first force magnitude of a first touch input based on the set of electrical values.

Abstract: One variation of a system includes a substrate including: a first layer including a first spiral trace coiled in a first direction; a second layer arranged below the first layer and including a second spiral trace coiled in a second direction and cooperating with the first spiral trace to form a multi-layer inductor; and a sensor layer including an array of drive and sense electrode pairs. The system also includes: a cover layer arranged over the substrate and defining a touch sensor surface; and a first magnetic element arranged below the substrate and defining a first polarity facing the multi-layer inductor. The system further includes a controller configured to drive an oscillating voltage across the multi-layer inductor to oscillate the substrate in response to detecting an input on the touch sensor surface based on electrical values from the set of drive and sense electrode pairs.

Abstract: One variation of a system includes: a frame; a sensor module; and a controller. The frame includes: a base structure that locates a display defining a front face of a device; and a lateral frame structure extending along and adjacent an edge of the display and supported on a side of the base structure. The base structure and the lateral frame structure cooperate to define a channel arranged behind the display and extending longitudinally between the lateral frame structure and the side of the base structure. The sensor module is arranged in the channel and includes: a substrate; and a linear array of sensors arranged on the substrate and outputting sense signals representing local deflections of the lateral frame structure. The controller detects locations and force magnitudes of side inputs on the device, proximal the edge of the display, based on sense signals output by the linear array of sensors.

Abstract: A method for calibrating a touch sensor includes: at a calibration system during a calibration routine, applying a probe, at a target selection force, to a sequence of locations on a touch sensor surface of a touch sensor; at the touch sensor, capturing a sequence of touch images representing magnitudes of forces detected on the touch sensor surface during the calibration routine; fusing the sequence of touch images into a response map representing magnitudes of forces detected on the touch sensor surface by the touch sensor responsive to application of the target selection force on the touch sensor surface by the probe during the calibration routine; generating a force compensation map defining threshold forces for detecting selections at the target selection force on the touch sensor surface based on the response map.
