Abstract
A method includes detecting a first signal on first electrodes along a first axis of a digitizer sensor, detecting a second signal on second electrodes along a second axis of the digitizer sensor, determining that hand input exists over the first electrodes based at least on the first signal and no hand input exists over the second electrodes. A first phase of the first signal detected on the second electrodes is determined. A second phase of the second signal detected on the first electrodes is estimated based on the first phase and a portion of the first signal associated with the second phase is extracted. Coordinates of a handheld device is determined based on the portion of the first signal extracted from the first electrodes and the second signal and the coordinates are reported to a host computing device associated with the digitizer sensor.
