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.

Abstract: A system includes: a substrate including an edge supported by a chassis; a first electrode spanning a first area of the substrate and arranged proximal a center of the substrate; and a second electrode spanning a second area, greater than the first area, on the substrate and interposed between the first electrode and the edge of the substrate. The system further includes a first coupling region: facing the first electrode; and electrically coupling to the first electrode to yield a first electrical value at the first electrode responsive to application of a first force magnitude proximal the center of the substrate. The system also includes a second coupling region: facing the second electrode; and electrically coupling to the second electrode to yield a second electrical value, approximating the first electrical value, at the second electrode responsive to application of the first force magnitude proximal the center of the substrate.

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: 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 touch sensor system includes a set of touch layers: spanning a first area; and including a set of electrodes. The system further includes a set of inductor layers: arranged below the set of touch layers; spanning a second area less than the first area; and including a set of spiral traces defining an inductor. The system also includes a magnetic element arranged below the set of inductor layers and defining a first polarity facing the inductor. The system further includes a controller configured to: read a set of electrical values from the set of electrodes; interpret a force magnitude of a touch input based on the set of electrical values; and in response to the force magnitude exceeding a force magnitude, drive an oscillating voltage across the inductor to induce alternating magnetic coupling between the inductor and the magnetic element.
