A user interface for an infotainment system of a motor vehicle includes a rectangular display screen and a rotatable ring having a central circular viewing window through which the display screen is visible. The rotatable ring includes a plurality of rotational positions relative to the display screen. An optical switch is disposed between the rotatable ring and the display screen and detects the rotational position of the rotatable ring. An electronic processor is communicatively coupled to the display screen and to the optical switch. The electronic processor controls an image presented on the display screen dependent upon the rotatable position of the rotatable ring as detected by the optical switch.
