Human-machine interaction (HMI) is a field that encompasses hardware and software components that enable users to interact with machines. It has a wide range applications in both personal and professional settings. In this article, we’ll examine the definition of human-machine interaction, use cases and trends.
HMI was born out of the need to create more user-friendly interfaces for computers. It combines elements from a number of different fields, including ergonomics, psychology, cognitive engineering, and linguistics. The term was first created by Douglas Engelbart, who believed that humans could be taught to operate computers through well-designed interfaces.
An example of human-machine interfacing is an HMI terminal, also known as an operator interface terminal (OIT), also known as a local operator interface (LOI) or man machine interface(MMI). These devices communicate with PLCs within automation systems, translate input and output data to digital dashboards, and allow for control. They can also display and manage alarms using real-time data. HMIs are typically found in ATM machines, gas stations self-checkout lines, as well as manufacturing facilities.
Another type of HMI is a touchscreen screen that interprets user’s movements and executes commands in line with the gestures. This technology is used in smartphones and tablets that come with touchscreens. They are now a part of our everyday lives. Pre-touch sensing is the newest development in the field of human-machine interaction. It anticipates the user’s intentions and executes the action before they have even given the instruction.
