Abstract: A method performs a scan operation for a single-layer sensor array that includes transmit (TX) electrodes and receive (RX) electrodes. The method includes determining whether to include a signal value for an RX electrode in a computation of a slope parameter value for a TX electrode. The method computes an index sum based on an index of the RX electrode when the signal value for the RX electrode is included in the computation of the slope parameter value for the TX electrode. The method computes a signal sum based on the signal value for the RX electrode when the signal value for the RX electrode is included in the computation of the slope parameter value for the TX electrode. The method then computes the slope parameter value for the TX electrode based on the signal sum and the index sum.

Another method calculates the touch orientation by calculating eigenvalues and eigenvectors.
