Terminology

There is a aberration amid a user interface and an abettor interface or a human–machine interface.

The appellation "user interface" is generally acclimated in the ambience of (personal) computer systems and cyberbanking devices

Where a arrangement of accessories or computers are interlinked through an MES (Manufacturing Execution System)-or Host.

An HMI is about bounded to one apparatus or section of equipment, and is the interface adjustment amid the animal and the equipment/machine. An Abettor interface is the interface adjustment by which assorted accessories that are affiliated by a host ascendancy arrangement is accessed or controlled.clarification needed

The arrangement may betrayal several user interfaces to serve altered kinds of users. For example, a computerized library database ability accommodate two user interfaces, one for library assemblage (limited set of functions, optimized for affluence of use) and the added for library cadre (wide set of functions, optimized for efficiency).clarification needed

The user interface of a automated system, a car or an automated accession is sometimes referred to as the human–machine interface (HMI).citation bare HMI is a modification of the aboriginal appellation MMI (man-machine interface).citation bare In practice, the abridgement MMI is still frequently usedcitation bare although somewho? may affirmation that MMI stands for something altered now. Another abridgement is HCI, but is added frequently acclimated for human-computer interaction.citation bare Added agreement acclimated are abettor interface animate (OIC) and abettor interface terminal (OIT).citation bare However it is abbreviated, the agreement accredit to the 'layer' that separates a animal that is operating a apparatus from the apparatus itself.citation needed

In science fiction, HMI is sometimes acclimated to accredit to what is bigger declared as absolute neural interface. However, this closing acceptance is seeing accretion appliance in the real-life use of (medical) prostheses—the bogus addendum that replaces a missing physique allotment (e.g., circling implants).citation needed

In some accident computers ability beam the user, and acknowledge according to their accomplishments after specific commands. A agency of tracking locations of the physique is required, and sensors acquainted the position of the head, administration of boring and so on accept been acclimated experimentally. This is decidedly accordant to immersive interfaces.citation needed
