Abstract
A user interface for an audio/visual device takes measurements of a touch sensor that are indicative of the current position of a tip of a finger of a user against a touch-sensitive surface of the touch sensor on a recurring basis, maintains a predetermined quantity of those measurements in a storage accessible to a processing device implementing at least a portion of the user interface, and employs measurements taken of the touch sensor at a predetermined amount of time into the past in response to an indication of the user having exerted increased pressure against the touch-sensitive surface via the tip to determine the position of that tip at a time relatively shortly before the user began to exert the increase in pressure.
