Abstract
One variation of a keyboard system includes: a substrate including an array of inductors; a tactile layer arranged over the substrate defining an array of key locations over the array of inductors; an array of magnetic elements, each arranged within the tactile layer at a key location configured to inductively couple to an adjacent inductor and configured to move relative to the adjacent inductor responsive to application of a force on the tactile layer at the key location; and a controller configured to read electrical values from the inductors. In response to detecting a change in electrical value at a first inductor, the controller also configured to: register a first keystroke of a first key type associated with a first key location defined over the first inductor; and drive an oscillating voltage across the first inductor to oscillate the tactile layer over the substrate during a haptic feedback cycle.
