MenschMaschineInterfaces, abbreviated MMI, denotes the set of devices, software, and protocols that enable humans to interact with machines, processes, and systems. The term is used across industrial automation, consumer electronics, automotive interfaces, medical equipment, and building management. An MMI typically integrates input devices (buttons, switches, keyboards, touchscreens, voice), output devices (displays, indicators, alarms, speakers), and software that translates human actions into control signals and presents system status to the operator.
Modern MMIs often form part of a layered architecture including field devices, programmable logic controllers or
Applications range from monitoring temperatures and processes in factories to operating robots, vehicle dashboards, and hospital
