Abstract:
A method and apparatus perform a first scan of an input device and determine that a first signal profile received through the first scan is outside a range of a reference signal profile. The method and apparatus perform a second scan of the input device responsive to the first signal profile being outside the range of the reference signal profile and use a second signal profile received through the second scan to detect a presence of an input object at least proximate to the input device.
