HMI stands for Human-Machine Interface and refers to specially designed electronic display interfaces, which are intended to connect a person to a machine, device, or system. They are engineered to facilitate a streamlined use of machinery or systems by connecting human interactions through insights into mechanical functions, performance, and progress.
Integrated HMI displays eliminate the requirement of physical wires, switches, and controls, and incorporates software as an alternative to the physical element. This allows the users to access and carry out different functions of the machinery or systems.
What is MMI?
MMI, or a Multi-Media Interface, refers to a single integrated interface that is capable of controlling a diverse range of devices and functions. They can operate different components, including entertainment elements and electronics. MMI displays are widely used in cars as a central console, enabling different functions like satellite navigation, traffic management, radio control, music control, aux audio port, climate control, seat heating, HVAC, and so on.
What is OIT?
OIT refers to the Operator Interface Terminal. It is an operating system interface designed to retrieve and process information with more accuracy and precision. The OIT is extremely flexible and robust when combined with an HMI display, and enables the Human-Machine Interface to maximise its performance by establishing better control over data and work processes.
Applications of HMI / MMI / OIT
HMI / MMI / OIT displays have a multitude of applications. The key applications include:
Industrial automation displays
Medical heart monitoring and patient monitoring systems
Advanced Driver Assist Systems displays with integrated video output
Car control panels and entertainment systems
Display driving, frame grabbing, graphic rendering, and video processing
