HUMAN-COMPUTER INTERFACE SYSTEM
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.
1 . A system comprising:
a first set of layers;
a first set of electrodes arranged on the first set of layers;
a second set of layers arranged below the first set of layers;
a first inductor coupled to the second set of layers;
a first magnetic element facing the first inductor; and
a controller configured to:
read a first set of electrical values from the first set of electrodes;
interpret a force magnitude of a touch input applied to the first set of layers based on the first set of electrical values; and
in response to the force magnitude exceeding a threshold force magnitude, apply a first power signal across the first inductor to induce alternating magnetic coupling between the first inductor and the first magnetic element.
