Abstract
A control knob controls jog/shuttle operations on an audio/video payback/record device. The knob is formed of a cylindrical body having an outer portion and a face portion that has convex and concave regions, respectively, integral with each other. The convex region lies centered within, and surrounded by the concave region and with the two regions joined with a smooth radius transition. The smooth radius transition creates a topology that allows manipulation of the knob with only a small frictional force by a single finger of a user (not shown), thus allowing precisely rotation of knob to enter a jog mode at any angular position of the finger.
