Abstract: One variation of a system for detecting and responding to touch inputs with haptic feedback includes: a magnetic element rigidly coupled to a chassis; a substrate; a touch sensor interposed between the substrate and a touch sensor surface; an inductor coupled to the substrate below the touch sensor surface and configured to magnetically couple to the magnetic element; a coupler coupling the substrate to the chassis, compliant within a vibration plane approximately parallel to the touch sensor surface, and locating the inductor approximately over the magnetic element; and a controller configured to intermittently polarize the inductor responsive to detection of a touch input on the touch sensor surface to oscillate the substrate in the vibration plane relative to the chassis.

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.
