The system uses touch input to determine if a driver or passenger is operating the navigation system. If the system determines that the driver is operating the system, then an action is initiated (e.g., the user interface is locked down, a warning is provided). The navigation system allows a passenger in the vehicle to operate the navigation system while the vehicle is in motion. In an aspect, additional or other sensors (e.g., seat sensor, seat belt sensor, infrared sensor) can be used to detect whether a driver or passenger is operating the navigation system while the vehicle is in motion. ## Claims ### Claim 1 A method comprising: obtaining touch input via a touch-sensitive display of a system configured for operating in a vehicle, wherein the touch input corresponds to one or more contacts detected on the touch- sensitive display and comprises touch data from one or more touch sensors of the touch-sensitive display;
