Abstract
An input device including a sensing region is disclosed. The input device includes: sensor circuitry configured to: operate, during a first timeslot, electrodes as a first cluster; and operate, during a second timeslot, the electrodes as a second cluster, where the electrodes are aligned with an axis, and where at least one of the electrodes operates as a transmitter in the first cluster and as a receiver in the second cluster; and determination circuitry configured to: determine a first set of signal values associated with a first set of electrodes in the first cluster; determine a second set of signal values associated with a second set of electrodes in the second cluster; and generate a profile for the sensing region based on the first set of signal values and the second set of signal values, where the profile reflects an input object in the sensing region.
