Abstract
A touch system for determining the position of a touch on a touch sensor includes a touch sensor and a user contact point separate from the touch sensor. Information from both the user contact point and a touch to the touch sensor is used to determine the position of the touch on a touch sensor. Multiple contact points or touch sensors may be incorporated into the touch system. The touch system may be configured to selectively activate the touch sensors and contact points and distinguish between information generated from the touch sensor and contact point.
