What is an HMI?

HMI stands for Human-Machine Interface.

Automation software and hardware advances reduce programming tasks and provide more built-in configurability, scalability, background communication among software components, simulation/digital twin capability, and usability. 

In this day and age, human machine interfaces (HMIs) are everywhere. Think about every point of contact a human has with technology and it becomes a reminder that as humans, we interact with machines in just about every aspect of our lives. Self-service checkouts at supermarkets, using a SAT NAV or getting some cash at cash machines are all examples of instances when humans interact with an interface designed to help foster human/machine communication.
