A vehicle apparatus includes a seat and a transducer configured to vibrate such that a vibration is felt by a person sitting in the seat. A transducer control signal that is transmitted to the transducer is based on output from a sensor of the apparatus configured to measure data including parameters indicative of at least one of a vehicle system function, a vehicle environment, and driver state, or on output from the vehicle system indicating parameters related to the vehicle system, vehicle environment, or driver state.
