Classification: CPC G  B | IPC B  G

Claim 15:
16. A non-transitory computer-readable medium having processor-executable instructions stored thereon, the processor-executable instructions, when executed, facilitating performance of the following:
obtaining, using a set of rotation electrodes that interact with a knob interface, first resulting signals and second resulting signals, wherein obtaining the first resulting signals and the second resulting signals comprises:
obtaining, from the set of rotation electrodes, the first resulting signals, wherein the first resulting signals are obtained without providing a reference signal to a set of reference signal electrodes that interact with the knob interface; and
obtaining, from the set of rotation electrodes, the second resulting signals, wherein the second resulting signals are obtained in response to providing the reference signal to the set of reference signal electrodes;

determining an initial state of the knob interface using the first resulting signals and the second resulting signals;
obtaining, 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 a rotational direction of the knob interface using the first resulting signals, the second resulting signals, and the third resulting signals; and
adjusting a setting using the determined rotational direction.
