First Claim
Patent Images
1. A virtual knob interface comprising:
- a substrate;
a plurality of touch sensors, each of said touch sensors comprising at least one sensing electrode associated with said substrate, each of said touch sensors adapted to emit an electric field about the respective at least one sensing electrode;
a virtual knob associated with said substrate and said plurality of touch sensors, said virtual knob defining a guide corresponding to the locations of said electric fields, said guide being adapted for navigation by a stimulus external to said virtual knob.

Abstract
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.
