Human-Machine Interface (HMI)
Introduction
The user interface, or UI (from English User Interface, UI), is the means that allows communication between a user and a machine, equipment, computer or device, and includes all points of contact between the user and the equipment.
They are normally easy to understand and easy to operate, although in the field of computing it is preferable to refer to them as being "usable", "friendly and intuitive" because it is complex.
Definition
The user interface is the space where interactions between humans and machines occur. The objective of this interaction is to allow the most effective operation and control of the machine from interaction with the human.
Basic user interfaces are those that include elements such as windows, menus, graphic content, cursor, sounds, and in general, all those channels through which communication between the human being and the machine is allowed.
The goal of interface design is to produce an interface that is intuitive (self-explanatory), efficient, and enjoyable so that operating the machine gives the desired results.
There is a difference between a user interface and an operator interface or a human-machine interface (HMI).
In science fiction, HMI is sometimes used to refer to what is best described as a direct neural interface. However, this latter usage is having increasing application in the real-life use of (medical) prostheses, the artificial extension that replaces a missing body part (e.g., cochlear implants).[5][6].
In some circumstances, computers can observe the user and react according to their actions without specific commands.[7] A means of tracking body parts is required), and sensors that take note of head position, direction of gaze, etc. have been used experimentally. This is particularly relevant for immersive interfaces").[8][9].
