1. A method comprising: based on a first scan of a set of sensor electrodes of the touch-sensing surface, calculating a first resolved location for a conductive object proximate to a touch-sensing surface, wherein the first resolved location is represented as touch coordinates identifying a point on the touch-sensing surface where the conductive object is located; predicting an approximate location for the conductive object based on the first resolved location, wherein the predicting comprises selecting a subset of sensor electrodes within an area surrounding the approximate location to be scanned in a second scan; and determining a second resolved location for the conductive object in the second scan based on the predicted approximate location by, scanning the subset of sensor electrodes of the touch-sensing surface without scanning the entire set of sensor electrodes, wherein the number of sensor electrodes in the subset of sensor electrodes is fewer than the number of sensor electrodes in the set of sensor electrodes; identifying that the conductive object is located at an edge of the area or outside of the subset of the sensor electrodes based on the scanning of the subset of sensor electrodes; and in response to identifying that the conductive object is located at the edge of the area or outside the subset of sensor electrodes, scanning at least one or more additional rows or columns of sensor electrodes that are adjacent to the subset of sensor electrodes without scanning the entire set of sensor electrodes.
