What is the human-computer interaction interface? What are the functions of the human-computer interaction interface?

Human-Computer Interaction Interface (HCI or HMI), also known as man-machine interface (MMI), operator interface terminal (OIT), local operator interface (LOI) or operator terminal (OT), refers to the communication media or means between people and computer systems. It is a platform for two-way information exchange of various symbols and actions between people and computers.

The main function of the human-computer interaction interface is to convert human intentions into a form that the computer can understand and process, and at the same time convert the computer's feedback into a form that humans can perceive and understand. This enables users to interact with the computer system conveniently and intuitively, improving work efficiency and user experience.

The human-machine interface is mainly composed of two parts: hardware and software. The hardware part includes processor, display unit, input unit, communication interface, data storage unit, etc. The performance of the processor determines the performance of the HMI product and is the core unit of the HMI. The software part includes system software running in the HMI hardware and screen configuration software running under the PC operating system.

Human-computer interaction interfaces are widely used in various fields, such as industrial automation, smart home, e-commerce, online education, etc. In these fields, human-computer interaction interfaces not only improve the usability and user experience of the system, but also improve work efficiency and reduce costs through intelligent and automated means.

With the continuous development of science and technology, the human-computer interaction interface is also evolving. At present, the human-computer interaction interface is developing in a more natural, intelligent and personalized direction. For example, through natural interaction methods such as voice recognition and gesture recognition, users can interact with computer systems more intuitively; through the application of artificial intelligence and big data technology, the human-computer interaction interface can understand the user's intentions and needs more intelligently and provide more personalized services.

The functions of the human-computer interaction interface mainly include the following aspects:

Input function:

One of the primary functions of the human-computer interaction interface is the input function, which allows users to input instructions or data to the computer through different methods (such as keyboard, mouse, touch screen, etc.). This function enables the computer to receive and process user information for subsequent operations or feedback.

Output function:

The human-computer interaction interface feeds back the information, results or error prompts processed by the computer to the user. This information can be presented to the user through screen display, sound prompts, printouts, etc., to help the user understand the working status or results of the computer.

Automatic data recording function:

By utilizing the data flow within the system, the human-computer interaction interface can automatically store data into the database and display or generate reports regularly. This function is very useful in data management and monitoring, and can help users quickly obtain and analyze data.

Alerts and information notifications:

When certain conditions are met, the human-computer interaction interface will trigger an alarm or information notification to ensure that users can handle important events or abnormal situations in a timely manner. This is of great significance to ensure the safe and stable operation of the system.

Graphical interface control:

Graphical interface control allows operators to directly control machines and other devices through a graphical interface. This design is designed to simplify the user's learning curve and improve operational efficiency. At the same time, when certain specific alarm conditions are met, the system will trigger an alarm to ensure that the operator can handle it in time.

Information conversion:

The human-machine interface is responsible for converting information into a form acceptable to humans, especially in the HMI (Human-Machine Interface) system. This includes converting the data inside the computer into human-readable text, charts, etc.

Historical and real-time data trend display:

The human-computer interaction interface can quickly display the captured data and automatically store it in the database for later viewing. At the same time, the real-time data trend display can immediately display the captured data to help users understand the real-time status of the system.

Report generation and printing:

The report generation and printing function allows the data to be converted into a printable format, which is convenient for users to manage and analyze. This is very useful for scenarios that require regular reporting or recording of data.

Control functions:

The control function enables users to intervene in the computer and its operating environment, including the management of applications, files and system settings. This function allows users to customize and adjust the working state of the computer according to their needs.

In summary, the functions of the human-computer interaction interface cover input, output, data management, alarm notification, graphic control, information conversion, data display, report printing and control, etc. The synergy of these functions makes the human-computer interaction interface an important bridge connecting people and computers, providing users with efficient and convenient operation experience.
