User interface

In general, the user interface is a set of physical and logical principles of interaction of technical means, that is, a set of temporary agreements and rules of algorithms for the exchange of data between components. Often, an interface is called software and hardware that implements interfacing between nodes and devices of computing systems. This concept extends to all physical and logical means of interaction between the computing system and the external environment, for example, the operating system with the operator, and so on.

User Interface: Views

It is accepted to distinguish them by such characteristics as the method of connection, the structure of the connections, the method of data transmission, synchronization and the principles of control. It is possible to distinguish the intra-machine interface, which is a conjugation of blocks and nodes to each other. There are two options for organizing this kind of interface: multiplex, in which each block of the computer is connected by its local wires to other blocks; Simply connected, as a result, all the computer blocks are connected through a common system bus to each other.

The external interface is a system of communication of the system unit with the periphery of the computer or with other computers. It is also customary to distinguish several types: interfaces of peripheral devices, network interfaces.

The user interface or human-computer interface is the way of interaction between a person and a computer. If he responds to user needs and knows his weaknesses, then he is human-oriented. The machine part of the interface is the part that is implemented in a machine that uses the capabilities of computer technology. The user interface is the part that is implemented by a person in the light of weaknesses, needs, habits, and the ability to learn and other factors. The system of state and international standards prescribes how the most common interfaces should look.

User Interfaces: Classification

There are three types: command, SILK and WIMP. At the command interface, the process of interaction between a person and a computer is made by submitting commands to the computer, then the result is given to the user. At the moment, this technology is practically not applied. WIMP differs in that the dialogue between the computer and the person is carried out with the help of graphic windows, menus and other similar elements. While this interface also sends signals to the machine, it is done through graphic elements. At the moment, the graphical user interface is an integral part of any computer. It was implemented in two different levels: a simple and complete WINP interface.

The SILK-interface is the closest to the familiar form of communication. In his framework, a normal conversation between a person and a computer takes place. The computer analyzes human speech and finds in it commands for itself, and then realizes them. The result of the execution of commands is translated into an understandable form for a person. The SILK interface uses: a semantic interface; Speech technology; Mimic interface.

Currently, all types of computers use the WIMP interface. The user interface is closely related to psychology and ergonomics. Psychology studies human behavior in different situations, its mentality, intellect, external and internal factors of irritation, reactions and habits. Ergonomics deals with the principles of human interaction with machines. With a thorough study of all this, programmers manage to create friendly interfaces with which the user is comfortable to work with.
