VIRTUAL KNOB INTERFACE AND METHOD

摘要

A virtual knob interface includes a substrate, a virtual knob associated with the substrate, and a number of touch sensors associated with the substrate and with the virtual knob. The virtual knob and touch sensor are configured and arranged such that the touch sensors detect manipulation of the virtual knob by a user. The knob can be removable from the substrate. Features can be provided to disable control of a device or function controlled by the knob when the knob has been removed.
