Abstract
An apparatus may include processing logic coupled with a force sensor input and a touch sensor input. The processing logic is configured to determine a relative force magnitude based on a force signal received at the force sensor input and a baseline measurement of the force sensor. The processing logic updates the baseline measurement in response to detecting that the touch signal indicates the absence of the one or more touches from the sensing surface.
