mmi

MMI is a three-letter acronym used in several different domains, and its meaning varies by context. This article outlines a few of the more common uses.

Multi Media Interface (Audi) is an in-car infotainment system developed by the German automaker Audi. It centralizes control of audio, navigation, telephone, vehicle settings, and other functions through a central display and input methods such as a rotary dial, buttons, and later touch controls. Over time, MMI has evolved to include larger screens, handwriting and gesture input, voice control, and advanced connectivity, making it a core part of Audi’s in-car user experience.

Man–Machine Interface refers to the broader concept of interaction between humans and machines, particularly in industrial, manufacturing, or control-system environments. MMIs describe the user interfaces that operators use to monitor and control processes, equipment, or robotics. The term is sometimes used interchangeably with human–machine interface (HMI), though HMI is more common in contemporary literature and practice. Effective MMIs emphasize clarity, safety, and reliability and are designed to reduce operator error and latency.

Momentum Metropolitan Holdings, often abbreviated MMI, is a South African financial services company. It operates across life and health insurance, asset management, and retirement solutions. The group has undergone branding and structural changes over the years and is a notable example of a large, diversified financial services firm associated with the MMI acronym.
