In Industrial manufacture, such as cement manufacture, fertilizer, steel, the production process are controlled by Human / operator. Operator able to control the process with HMI equipment. HMI (Human Machine Interface) is a medium for information exchange and mutual communication between electromechanical system’s and the user. It allows the user to complete settings through touchable images or keys on the user-friendly window. This is not only offer’s fast and convenient control of manufacturing automation, but also has replaced traditional controlling panel’s which need extensive wiring.
The user interface, in the industrial design field of human–machine interaction, is the space where interaction between humans and machines occurs. The goal of this interaction is effective operation and control of the machine on the user’s end, and feedback from the machine, which aids the operator in making operational decisions. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.
An user interface is the system by which people (users) interact with a machine. The user interface includes hardware (physical) and software (logical) components. User interfaces exist for various systems, and provide a means of:
- Input, allowing the users to manipulate a system
- Output, allowing the system to indicate the effects of the users’ manipulation
Generally, the goal of human-machine interaction engineering is to produce a user interface which makes it easy, efficient, and enjoyable to operate a machine in the way which produces the desired result. This generally means that the operator needs to provide minimal input to achieve the desired output, and also that the machine minimizes undesired outputs to the human.
With the increased use of personal computers and the relative decline in societal awareness of heavy machinery, the term user interface is generally assumed to mean the graphical user interface, while industrial control panel and machinery control design discussions more commonly refer to human-machine interfaces.
