Definitions Edit

The human-machine interface (HMI) (also called human-computer interface (HCI) or Human-to-Machine (H2M))

is the place where the human and the machine meet. It includes how people communicate instructions to computing systems, what computing systems provide in response, and how hardware, software, systems, and devices can be designed to do more to expand human capabilities.
[t]he combination of hardware and software that allows a human to interact with a machine to perform a task.[1]
consists of the following:

Overview Edit

"An HMI can range from a physical control panel with buttons and indicator lights to an industrial PC with a color graphics display running dedicated HMI software."[3]

HMI/HCI includes software and hardware that allows human operators to monitor the state of a process under control, modify control settings to change the control objective, and manually override automatic control operations in the event of an emergency. The HMI also allows a user to configure or control algorithms and parameters in the system. The HMI also displays status information, historical information, reports, and other information to operators, administrators, managers, business partners, and other authorized users. The location, platform, and interface may vary a great deal. For example, an HMI could be a dedicated platform in the control center, a laptop on a wireless LAN, or a browser on a system connected to the Internet.
