Abstract
The various implementations described herein include systems, methods and/or devices used to enable underwater non-conductive touch tracking. An exemplary method is performed at a touch sensitive device and includes: detecting submersion of a capacitive sense array (CSA), including detecting increased electrode responses from at least a subset of a plurality of sensor electrodes of the CSA that exceed a predetermined electrode response criterion. The method further includes: (1) identifying one or more normalization factors for the CSA based on the detected increased electrode responses from the subset of the plurality of sensor electrodes, and (2) normalizing, using the one or more normalization factors, the CSA to form a substantially uniform baseline response across the CSA. The method further includes during the submersion, and subsequent to the normalizing, identifying one or more subsequent electrode responses that differ from the substantially uniform baseline response by at least a threshold amount.
