Human-machine interface (HMI) is the field that includes hardware and software components to enable people to communicate with machines. It offers a range of applications in both personal and professional environments. In this article, we will explore the definition of human-machine interaction as well as use cases, aspects, trends, and more.
HMI was born out of the need to create more user-friendly interfaces for computers. It combines elements from many different fields including ergonomics, psychology, cognitive engineering, and linguistics. Douglas Engelbart coined the term believing that humans could learn to operate computers through well-designed interfaces.
HMI terminals, also known as operator interface terminals (OIT) are an example of human-machine interactions. They are also referred to as local operator interfaces (LOI) or man machine interfaces (MMI). These devices communicate with PLCs in automation systems, process and convert input and output data into digital dashboards and facilitate control. They also manage and display alarms by using real-time data. HMIs are found in ATMs, gas stations Self-checkout lines, manufacturing facilities.
A touch-sensitive display is another kind of HMI that interprets the user’s movements to execute commands. This technology is used in tablets and smartphones with touchscreens integrated. They’re now part of our everyday lives. Pre-touch sensing is the newest technology in machine-human interaction. It anticipates the user’s intentions and performs the action before they’ve even spoken the command.
