Engineering Human Machine Interface (HMI) Systems

Human machine interface (HMI) – also known as User Interface (UI), Operator Interface Terminal (OIT) or Man Machine Interface (MMI) – encompasses hardware and software solutions for information exchange and communication between systems/machines and a human operator. HMIs enable control, management and/or visualization of device processes and can range from simple inputs on a touch display to control panels for highly complex industrial automation systems. HMIs can be found in multiple locations such as portable handheld devices, on machines, centralized control rooms, as well as factory floor machine and process control. Applications include industrial and building automation, digital signage, vending machine, medical, automotive, and appliances.
