Patent ID: 8773386

Claim:
A method comprising: detecting a presence of an input object proximate to a second electrode associated with a second axis of an input device and not detecting the presence of the input object proximate to a first electrode associated with a first axis of the input device, comprising: performing a first scan of the input device, wherein the first scan includes receiving first sensor signals from a plurality of electrodes; determining that a first signal profile that is based on the first sensor signals is outside of a range of a reference signal profile, wherein signal profiles determined to be within the range of the reference signal profile indicate presence of an input object; performing a second scan of the input device responsive to the first signal profile being outside of the range of the reference signal profile, and the detecting the presence of the input object proximate to the second electrode, wherein the second scan includes receiving second sensor signals from another pluraltiy of electrodes; and using the second sensor signals to detect the presence of the input object at least proximate to the first electrode.
