In one embodiment, an apparatus comprises a sense unit and a drive unit. The sense unit is operable to sense a first signal from drive lines of a touch sensor. The touch sensor comprises the drive lines and sense lines arranged relative to the drive lines such that intersections of the drive lines and the sense lines form one or more capacitive nodes. The drive unit is operable to transmit a second signal based on the first signal to the sense lines such that transmission of the second signal changes the perceived capacitance of the one or more capacitive nodes.

In one embodiment, an apparatus comprises a touch sensor comprising a touch-sensitive area, and a touch-sensor controller coupled to the touch sensor. The touch-sensor controller is operable when executed to: select one or more regions associated with a stylus within the touch-sensitive area, and scan one or more electrodes within each region.

In certain embodiments, an apparatus includes a touch sensor that includes a touch-sensitive area and a touch-sensor controller. The touch-sensor controller is operable to: select a first region around a determined first location associated with an object within the touch-sensitive area, select a second region around the determined first location associated with the object within the touch-sensitive area, and scan two or more electrodes within the first region and two or more electrodes within the second region to determine a second location associated with the object within the touch-sensitive area.
