A Human-Machine Interface or hmi is fairly literally wherein the human and the machine meet. This is the part of the human as well as the section of the machine that will interact in a specified task. Interaction include feel, vision, sound, heat transference and other physical or cognitive function. This can be referred to as Man-Machine Interface by a few. A good example of this is the common computer station which may have 4 human-machine interfaces, the keyboard (hand), the mouse (hand), the monitor (eyes) and the speakers (ears).
