Touch-based user interface user selection accuracy enhancement
First Claim
1. An apparatus comprising:
- a touch sensor providing a touch-sensitive surface enabling the position of a tip of a digit of a user to be recurringly determined as the user moves the tip across the touch-sensitive surface while keeping the tip in contact with the touch-sensitive surface, and able to detect an increase in pressure exerted against the touch-sensitive surface through the tip to make a selection;
a processing device; and
a storage accessible to the processing device and storing a sequence of instructions that when executed by the processing device, causes the processing device to;
take a set of measurements from the touch sensor indicative of the position of the tip on a recurring basis;
maintain a predetermined quantity of the most recently taken sets of measurements indicative of the position of the tip in the storage; and
in response to receiving an indication of an increase in pressure exerted against the touch-sensitive surface through the tip being detected;
access one of the sets of measurements indicative of the position of the tip taken at a predetermined amount of time into the past; and
employ the one of the sets of measurements to determine a position of the tip at a time prior to the increase in pressure being exerted against the touch-sensitive surface.

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.

5. A method comprising:
-
recurringly taking a set of measurements from a touch sensor indicative of the position of a tip of a digit of a user on a touch-sensitive surface of the touch sensor as the user moves the tip across the touch-sensitive surface while keeping the tip in contact with the touch-sensitive surface; maintaining a predetermined quantity of the most recently taken sets of measurements indicative of the position of the tip; and in response to receiving an indication of an increase in pressure exerted against the touch-sensitive surface through the tip being detected, employing one of the sets of measurements to determine a position of the tip at a time prior to the increase in pressure being exerted against the touch-sensitive surface. - View Dependent Claims (6)
