First Claim
1. A method comprising, by one or more computing devices:
- receiving two or more output signals responsive to two or more capacitive couplings, each of the capacitive couplings occurring between a pointing object and one of two or more sensing areas within a sensing region, each of the sensing areas having a position within the sensing region; and
if two or more of the output signals each have an output-signal level that exceeds a predefined activation level, then selecting a particular one of the sensing areas with output-signal levels exceeding the predefined activation level as an intended one of the sensing areas based on a predefined ranking scheme that takes into account the positions of the sensing areas within the sensing region.

Abstract
In one embodiment, a method includes receiving two or more output signals responsive to two or more capacitive couplings. Each of the capacitive couplings has occurred between a pointing object and one of two or more sensing areas within a sensing region, and each of the sensing areas has a position within the sensing region. The method includes, if two or more of the output signals each have an output-signal level that exceeds a predefined activation level, then selecting a particular one of the sensing areas with output-signal levels exceeding the predefined activation level as an intended one of the sensing areas based on a predefined ranking scheme that takes into account the positions of the sensing areas within the sensing region.
