Human Machine Interface (HMI) refers to the technology that enables interaction between operators and machinery or control systems. HMI systems typically include touchscreens, buttons, and graphical displays, allowing users to monitor processes, input commands, and receive real-time feedback. They play a crucial role in enhancing operational efficiency by providing intuitive visualizations of complex data, alarms, and control settings. Commonly used in industries such as manufacturing, energy, and transportation, HMIs improve user experience, streamline operations, and enhance safety by allowing operators to make informed decisions quickly and effectively in dynamic environments.
