Abstract: One variation for a seamless touch sensor includes: a substrate, a baseplate, a haptic actuator, a cover layer, and a controller. The substrate includes: a top layer including a set of drive and sense electrode pairs; and a bottom layer including an array of force sensors. The baseplate: is arranged below the substrate; and including an array of spring elements coupling the baseplate to the substrate. The haptic actuator is arranged below the substrate and includes: a multi-layer inductor; and a first magnetic element facing the multi-layer inductor. The cover layer is arranged over the substrate to define a continuous surface defining an active region and a inactive touch region. The controller is configured to drive an oscillating voltage across the multi-layer inductor to: induce alternating magnetic coupling between the multi-layer inductor and the magnetic element; and oscillate the active touch region of the cover layer relative to the magnetic element.

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 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 for a human-computer interface includes: a substrate; a post; and a controller. The substrate includes: a first region including a drive electrode concentric with a normal axis; and a second region arranged opposite the first region. The second region includes a set of sense electrodes arranged: radially about the normal axis; along a first axis orthogonal to the normal axis; and along a second axis orthogonal to the normal axis and the first axis. The post is arranged over the first region. The controller is configured to: read a set of electrical values from the set of sense electrodes; and based on the set of electrical values, interpret a first displacement of the drive electrode relative the set of sense electrodes along the first axis, and interpret a second displacement of the drive electrode relative to the set of sense electrodes along the second axis.

Abstract: A system includes: a substrate; a first electrode proximal a center on the substrate; and a second electrode interposed between the first electrode and an edge on the substrate. The system also includes a first coupling region: arranged on a first planar region of the baseplate; offset from the first electrode by a first height; and coupling to the first electrode to yield a first electrical value at the first electrode responsive to application of a force magnitude proximal the center. The system further includes a second coupling region: arranged on a second planar region, offset above the first planar region, of the baseplate; offset from the second electrode by a second height, less than the first nominal gap height; and 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 force magnitude.
