1. A method comprising:
- generating a correction value for a capacitive sensor based on a difference between a capacitance of the capacitive sensor and a capacitance of at least one other capacitive sensor when an input to the capacitive sensor and the at least one other capacitive sensor is absent; and
calculating a compensated capacitance value for the capacitive sensor based on applying the correction value to a difference between the capacitance of the capacitive sensor when the input is absent and another capacitance of the measured from the capacitive sensor.

Abstract
A method includes generating a correction value for a capacitive sensor based on a difference between a capacitance of the capacitive sensor and a capacitance of at least one other capacitive sensor when an input to the capacitive sensor and the at least one other capacitive sensor is absent. The method further includes generating a compensated capacitance value for the capacitive sensor based on applying the correction value to a difference between the capacitance of the capacitive sensor when the input is absent and another capacitance of the capacitive sensor.
