Abstract
A method and apparatus use a plurality of first region values to calculate a second region value, each of the plurality of first region values reflecting sensor element activity in a corresponding region of an input module, the second region value reflecting sensor element activity of a group of the corresponding regions. The method and apparatus determine that the input object is present relative to the group of the corresponding regions if the second region value meets or exceeds a threshold presence value.
