Claim:
1. A method of sensing at least one object in proximity to an array of sensors, comprising: making a determination that an object greater than a predetermined size has been detected, wherein the predetermined size is large relative to a finger touch; defining an ignore zone relative to the object that includes first sensor locations of the object and second sensor locations surrounding a least a portion of the first sensor locations, wherein defining the ignore zone includes determining that a sense value of at least one of the second sensor locations meets or exceeds a threshold sense value of the ignore zone, wherein the threshold sense value of the ignore zone is less than a first sense threshold associated with the first sensor locations; and removing the ignore zone after a predetermined duration, wherein determination of proximity of other objects outside of the ignore zone is processed differently than determination of proximity of objects inside of the ignore zone.
