HMI
HMI (Human Machine Interface) is the part of a system that allows people to interact with machines, particularly in cars and electronic devices. Think of it as the screens, buttons, and controls that let drivers and passengers use their car's entertainment system, navigation, or climate controls. It's similar to how a smartphone's screen lets you interact with apps, but for vehicles and other equipment. When people mention HMI in their resumes, they're usually talking about designing or developing these user-friendly interfaces that make complex technology easy for everyday users to understand and use.
