An ultrasonic haptic control system for a motor vehicle is provided. The system includes a steering wheel assembly comprising a ring-shaped member configured to be held by an occupant of the vehicle, and rotated about a central axis in order to steer the vehicle; and a plurality of ultrasound emitters associated with the steering wheel. The ultrasound emitters are configured to focus ultrasound waves within a central region about which the ring-shaped member circumferentially extends and/or radially outside of and adjacent to the ring-shaped member. The focused ultrasound waves are configured to form one or more haptic control surfaces. A method of operating a haptic control system is also provided.
