Touch screen with selective touch sources
First Claim
1. A vehicle touch screen system comprising:
- a touch sensor accessible from a driver position and a passenger position;
a first contact point associated with the driver position, the first contact point driven with a first signal, the first signal being transferred to the touch sensor through a driver in the driver position by a driver touch input on the touch sensor;
a second contact point associated with the passenger position, the second contact point driven with a second signal, the second signal being transferred to the touch sensor through a passenger in the passenger position by a passenger a touch input on the touch sensor; and
a processor configured to discern driver touch inputs from passenger touch inputs based on detection of the first or second signals on the touch sensor, and further configured to determine touch input location on the touch sensor using the detected first or second signals.

Abstract
The present invention provides a touch sensor system that distinguishes from among distinct users. As a vehicle touch sensor system, the present invention provides a touch sensor accessible from a driver position and a passenger position, a first contact point driven with a first signal and associated with the driver position, a second contact point driven with a second signal and associated with the passenger position, and a processor configured to discern users in the driver position touching the touch sensor from users in the passenger position touching the touch sensor based on detection of the first or second signals on the touch sensor. For example, the vehicle touch sensor system can be a navigation system. Distinguishing the driver from the passenger can allow touch inputs from the driver to be disabled when the vehicle is in motion, for example.
