For a studio course on interaction design, we were tasked with designing a context-specific control that has distinct input and outcome. The context I received was a car.  

Through observational research and prototyping, I designed an analog volume control for an autonomous vehicle. The interaction requires users to place “pebbles” onto a “bowl” in order to increase volume and remove pebbles to decrease volume. This design relies heavily on the context of a self-driving car and the development of a new, yet accessible mental model for volume control.
