Abstract
A data frame in a touch capacitive sensing circuit includes both mutual capacitance data and self capacitance data. The mutual capacitance data and self capacitance data of the frame are filtered to define mutual capacitance and self capacitance islands. Centroids of the mutual capacitance and self capacitance islands are calculated and then processed in a weighted mixing operation to produce a hybrid centroid that more accurately locates the coordinates of a detected touch/hover.
