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.
