Human-machine interfaces (HMIs) are systems that allow humans to interact with machines or devices. They can be found in various applications, from industrial control panels to consumer electronics. HMIs translate user inputs, such as touch or voice commands, into actions that machines can understand, facilitating effective communication between humans and technology. These interfaces can include visual displays, buttons, touchscreens, and even voice recognition systems. By improving usability and accessibility, HMIs enhance user experience and efficiency in operating machines. Examples of HMIs include smartphone interfaces, automotive dashboards, and industrial control systems.
