Touch Screen Calibration Sensor
First Claim
1. A device comprising:
- a touchscreen comprising a display and a touch input mechanism;
a second sensor mechanism located at a first location with respect to said touchscreen; and
a processor configured to;
cause said display to present an object in said first location;
receive a touch input from said touch input mechanism; and
determine a positional location of said touch input based on input from said second sensor.

Abstract
A touchscreen may be calibrated using a second sensor that may be placed around the periphery of the touchscreen in a known position with respect to the touchscreen. The second sensor may be incorporated into a bezel and may have one or more sensor elements. The second sensor may be used to sense the position of a user'"'"'s finger or stylus when the user touches an object on the touchscreen display, and the second sensor output may be used to update a calibration factor based on the position of the displayed object. The second sensor may be used to periodically recalibrate the touchscreen any time an object is selected in proximity to the second sensor.
