Abstract
Official abstract text for this publication.
A method of operating a touch-sensing surface may include performing a first scan of a first set of electrodes of a touch-sensing surface, determining a presence of at least one conductive object proximate to the touch-sensing surface, in response to determining the presence of the at least one conductive object, performing a second scan of a second set of electrodes of the touch-sensing surface, and repeating the performing the second scan until the at least one conductive object is no longer proximate to the touch-sensing surface.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: performing a first scan of a first set of electrodes of a touch-sensing surface, wherein the first set of electrodes comprises only row electrodes or only column electrodes of the touch-sensing surface, wherein performing the first scan comprises measuring a self capacitance for each electrode in the first set of electrodes; determining a presence of at least one conductive object proximate to the touch-sensing surface based on the fir…
