Abstract:
A method and device are provided for measuring force on a force enabled input device having a touch surface. The method includes detecting force information associated with an input object contacting the touch surface, and determining a push event if the force information is either greater than a predetermined static push threshold value, or a substantially monotonic increase of at least a dynamic push threshold value above a low baseline value. The method thereafter determines a release event if the force information either decreases below a predetermined static release threshold value, or decreases from a maximum baseline value by an amount greater than a dynamic release threshold value. The method initiates a first type of user interface action associated with the input object based on a determination of the push event and the release event, wherein the first type of user interface action may comprise determining a virtual button click.
