20090322710 | EXTENT CALIBRATION FOR ABSOLUTE INPUT SENSORS - A system and method for compensating for misalignment of a sensing surface of an absolute position input sensor is provided. In one embodiment, a first set of points is displayed on a display, the first set of points configured to represent a currently configured boundary edge. A user then traces around the physical boundary edge, and a second set of points is displayed the display, with the second set of points configured to represent the traced physical boundary edge. A user then enters a second input, and in response first set of points on the display screen is offset to align with the second set of points. From the second input, an actual boundary edge relative to the sensor surface is determined. Then, the output of the absolute position input sensor is adjusted to align with the determined actual boundary edge. | 12-31-2009 |
