Abstract
A user interface includes a rotatable ring for controlling a function on an associated device, and a support ring for supporting the rotatable ring. The support ring includes a plurality of biasing elements, and a plurality of engagement members rotatably mounted on the biasing elements and configured to engage the rotatable ring so as to preload the biasing elements and thereby (i) biasing the rotatable ring toward a center position in which a central axis of the rotatable ring is coincident with a central axis of the support ring, and (ii) increasing resistance to rotational movement of the rotatable ring.
