Abstract
A processing system for an input device is configured to communicate with a host system and comprises a sensor module and a determination module. The sensor module comprises sensor circuitry and is configured to transmit transmitter signals with a plurality of transmitter electrodes and receive resulting signals comprising effects corresponding to the transmitter signals. The determination module is configured to determine, based on the resulting signals and a touch threshold, first positional information associated with a pre-touch state of an input object and second positional information associated with a touch event by the input object. The determination module is further configured to communicate data associated with the first positional information to the host system only upon occurrence of the touch event.
