Peak Detection Schemes for Touch Position Detection

摘要

Apparatuses and methods of peak detection are described. One method measures touch data on a sense array, the touch data represented as multiple cells. The method performs multiple different peak-detection schemes on each of the cells to generate a list of one or more possible peaks in the touch data. The method selects one or more actual peaks from the list. The actual peaks are used to determine locations of touches proximate to the sense array.

1. A method comprising:
measuring, at a processing device, touch data on a sense array, the touch data represented as a plurality of cells; performing a plurality of different peak-detection schemes on each of the plurality of cells to generate a list of one or more possible peaks in the touch data; and selecting one or more peaks from the list of one or more possible peaks, wherein each of the one or more peaks is used to determine a location of a touch proximate to the sense array.
