Abstract
A capacitance sensing method may include performing a first scan of a plurality of sensor elements of a touch-sensing surface to detect a plurality of capacitance values indicating a presence of multiple contacts at the touch sensing surface. Based on the plurality of capacitance values, a plurality of coordinates may be calculated that indicate a plurality of possible contact locations for the multiple contacts. In response to detecting that the plurality of coordinates indicates the presence of the multiple contacts, a resolve scan of at least a first intersection of sensor elements may be performed, where the first intersection corresponds to at least one of the possible contact locations. Based on the resolve scan, at least one of the possible contact locations may be identified as an actual contact location of one of the multiple contacts.
