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.
Claims18
A system for determining the position of a touch on a touch sensor comprising a first user contact point separate from the touch sensor, wherein information from both the first user contact point and the touch on the touch sensor is used to determine the position of the touch on the touch sensor.

- collecting information from a first contact point, the first contact point being separate from the touch sensor;
- collecting information from the touch on the touch sensor;
- and
- determining the position of the touch on the touch sensor using information from both the first contact point and the touch sensor.
