Abstract
A method is provided. The method comprises: obtaining, by a processing system and using a set of rotation electrodes that interact with the knob interface, first resulting signals and second resulting signals; determining, by the processing system, an initial state of the knob interface using the first resulting signals and the second resulting signals; obtaining, by the processing system and using the set of rotation electrodes, third resulting signals indicating a first rotational state of the knob interface, based at least in part on the knob interface being rotated from the initial state to the first rotational state; determining, by the processing system, the rotational direction of the knob interface using the first resulting signals, the second resulting signals, and the third resulting signals; and adjusting, by the processing system, a setting using the determined rotational direction.
