Introduction to Human Machine Interface (HMI)

A human machine interface (HMI) is an interface which permits interaction between a human being and a machine. Human machine interfaces vary widely, from control panels for nuclear power plants to the screen and input buttons on a cell phone.

A human machine interface (HMI) is an interface which permits interaction between a human being and a machine. Human machine interfaces vary widely, from control panels for nuclear power plants to the screen and input buttons on a cell phone. Designing such interfaces is a challenge, and requires a great deal of work to make the interface functional, accessible, pleasant to use, and logical. Some engineers specialize in developing human machine interfaces and changing the ways in which people interact with machines and systems.


Two components are needed in a human machine interface. The first is an input. A human user needs some way to tell the machine what to do, to make requests of the machine, or to adjust the machine. Examples of input devices include keyboards, toggles, switches, touch screens, joysticks, and mice. All of these devices can be utilized to send commands to a system or even an interlinked set of systems.


The interface also requires an output, which allows the machine to keep the human user updated on the progress of commands, or to execute commands in physical space. On a computer, for example, users have a screen which can display information. A robot, on the other hand, may move in response to commands and store data on a hard drive so that people can see how the robot responds, learns, and navigates the world. Outputs can also include things as simple as status lights which alert people when toggles or switches have been activated.

The technology behind the human machine interface is constantly improving. Researchers have developed interfaces which can be controlled with the mind, for example, seeing applications for this technology among stroke patients and other people with severely restricted modes of communication. Likewise, outputs have become much more sophisticated over time.

As many people have noted, a poorly designed human machine interface can be extremely frustrating. On one end of the scale, the interface may be buggy or nonfunctional, causing difficulty because it does not work as intended. On the other end of the scale, the interface works, but it is designed in such a way that it is confusing and challenging to operate because it is not intuitive for users. The art of designing intuitive interfaces requires a deep understanding of how humans interact with their environment and an awareness of the psychology of designing interfaces in a way which will be accessible to a broad spectrum of humans. What works for an engineer in a human machine interface, for example, might not be as easy for a member of the general public.

Human Machine Interface Design:

• Outputs can also include things as simple as status lights which alert people when toggles or switches have been activated. The technology behind the human machine interface is constantly improving. Researchers have developed interfaces which can be controlled with the mind, for example, seeing applications for this technology among stroke patients and other people with severely restricted modes of communication.


• There are some companies that work on developing what are now only conceptual human-machine systems. These designs range from exoskeletons for industrial and military use that can be worn like a suit and allow the operator to lift weights far beyond what could normally be done, to fully articulated robots that can be used to work in dangerous environments or even under the ocean.

Human Machine Interface Software:

This system assists the pilot in flying the jet by observing vehicle tolerances, maintaining subsystems so the pilot does not have to do so, and taking initiative in alerting the pilot to anomalous conditions. During combat, the human-machine system can integrate the pilot's head motions with targeting computers that, in some cases, allow a pilot to simply look at a target to direct weapons fire in that direction.

Operator Interface:

• To control all of this functionality from a computer, DMX controller software has been developed. From the program’s interface, the user can set lights to go dimmer, go brighter, switch on and off and change color.

• The two most common terms for the industrial world are man-machine interface and human-machine interface. In processing and manufacturing, operator interface took over. In other areas, the term simply fell out of use without a replacement.
Human User Interface:

• User interface testing is quite common for both hardware and software, though with different goals and guidelines. Though different methods can be utilized for user interface testing, including both human testing and automated testing, the goal of such testing is typically the same.

• A user interface describes any mechanism by which a human interacts with a machine or computer. From automobiles to toasters to personal computers, nearly every mechanical and electrical device has a user interface.
Programmable Automation Controller:

• It is also important to estimate how many inputs and outputs will be needed on the device, and analyzes any special environmental or communication requirements in the usage location. In situations where an existing programmable logic controller is being replaced, the best option is usually to choose a PLC that is produced by the same manufacturer as the old unit.

• History PLCs were first created to serve the automobile industry. The first programmable logic controller project was developed in 1968 for General Motors to replace hard-wired relay systems with electronic controllers.
Human Computer Interface:

• These systems typically include calculations and displays of time and range to destination. Modern cell phones also include human-computer interaction design. Using the phone to find contacts, send messages, or retrieve voice mails requires a well- designed user interface.

• Outputs can also include things as simple as status lights which alert people when toggles or switches have been activated. The technology behind the human machine interface is constantly improving. Researchers have developed interfaces which can be controlled with the mind, for example, seeing applications for this technology among stroke patients and other people with severely restricted modes of communication.
