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 for a haptic actuator includes: a substrate; a baseplate; a magnetic element; and a set of spacer elements. The substrate includes: a first layer including a first spiral trace coiled in a first direction; and a second layer. The second layer is arranged below the first layer and includes a second spiral trace: coiled in a second direction opposite the first direction; and coupled to the first spiral trace to form an inductor. The substrate further includes terminals arranged about a periphery of the substrate and coupled to the inductor. The baseplate is arranged opposite the substrate. The magnetic element is: arranged on the baseplate; and defines a first polarity facing the inductor. The first set of spacer elements are: interposed between the baseplate and the substrate; arranged proximal edges of the baseplate; and defines a nominal gap between the magnetic element and the inductor.

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: A touch assembly includes: an outer tip; an inner tip; a circuit board; a vibration sensor; and a spring element. The outer tip includes a distal end defining an outer contact surface. The inner tip: is arranged concentrically within the outer tip; extends from the distal end of the outer tip; and defines an inner contact surface. The circuit board is arranged over a proximal end of the outer tip. The spring element: is interposed between the circuit board and the inner tip; couples the inner tip to a reference potential; and is configured to, during a haptic feedback cycle at a touch sensor in response to application of the inner tip toward the touch sensor, yield to locate the inner contact surface coplanar with the outer contact surface. The vibration sensor is arranged on the circuit board and configured to output vibration signals during the haptic feedback cycle.

Abstract: One variation of a method for modifying haptic feedback response includes, during a set-up period: at a calibration system, applying a target selection force, to a target location on a surface of a touch sensor; at the touch sensor, triggering vibration cycles across haptic actuators to oscillate the touch sensor surface; capturing a haptic waveform representing oscillations at the first target location on the surface during the vibration cycles; interpreting a vibration cycle for the haptic actuators corresponding to a target haptic intensity at the target location based on the haptic waveform. The method also includes, during a deployment period, following the set-up period: detecting a force magnitude for a touch input applied proximal the target location on the surface; and in response to the force magnitude exceeding the target selection force, triggering the vibration cycle at the haptic actuators to oscillate the surface at the target haptic intensity.

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.
