What is HMI?

Basically HMI stands for Human-Machine Interface. And it is simply a device that allows communication and data exchange between a user or operator and a machine or process. Most often an HMI is a touch screen but a simple keypad that gives orders to a process is also an HMI, the main concept being that with an HMI you can either give instructions to the process, get information about the process, or both.

And HMI basically has two types Keypad HMI and Touchscreen HMI. Also HMI is widely used in industries but you can also find HMI everywhere around you, simple example of HMI is ATM and ATM is the HMI you use to withdraw your money. In industrial applications, the major functions of HMI are real-time information exchange between operators and production processes. HMI screens display data, provide visual feedback, and execute operational commands through input devices such as touch screens and keyboards.
