An HMI (Human-Machine Interface) is a device or system that facilitates communication between humans and machines, most commonly in the form of a control panel with a display. It enables users to monitor, control, and configure machines, processes, or automation systems. Modern HMIs employ touchscreens, intuitive graphics, and visualization software to make even complex processes user-friendly.
HMIs are used in industry (production lines, PLC systems), transportation, HVAC systems, vending machines, and self-service terminals. They increase efficiency, safety, and usability, and their functions can be tailored to the requirements of specific applications.
