Human-computer interface (HMI) is a way of interaction and communication between a user and a computer. In recent years, with the rapid development of artificial intelligence, virtual reality, and augmented reality technologies, human-computer interfaces have been progressing and changing.
The simplest definition of a human-computer interface is an interface through which a person can issue commands to a machine, and through which the machine can return to the execution state and system state. Computer human-computer interface, also known as user interface, is the medium and dialog interface for transferring and exchanging information between human and computer, and is an important part of computer system.
The computer human-computer interface (HMI) is the medium of information exchange for interaction between the system and the user, which enables the conversion between the internal form of information (binary data) and human-acceptable forms, such as text, images, and sound. Human-computer interfaces exist in all areas that are involved in the exchange of information between the computer user and the computer system. Throughout the decades of computer technology development history, each time the human-computer interface changes have brought about a major leap in computer applications and computer technology.
With the development of digital circuits and computer technology, the functional division of future human-machine interface products will become less and less obvious, HMI functions will become more and more rich. HMI products larger than 5.7 inches will be all color display, screen life longer.
Due to the reduction in the cost of computer hardware, HMI products will be mainly tablet PCs for HMI hardware for high-end products, because such high-end products in the processor speed, storage capacity, the type and number of communication interfaces, networking capabilities, software resource sharing, etc. have great advantages, will be the future direction of development of HMI products. Of course, small size (display size less than 5.7 inches) HMI products due to its size and price advantages, with its further enhancement of functionality (such as increasing the IO function), will be widely used in small machinery and equipment for human-computer interaction applications.
The development of human-computer interface is characterized by
1. Human-computer interaction becomes closer to interaction with the real world. It provides new possibilities for reducing the cognitive burden of human interaction and making more use of the natural skills acquired from human evolution and experience.
2, the human-computer interface will increasingly have multi-modal high-bandwidth characteristics. There will be a big demand for group user interfaces that are adapted to the social organization and behavioral laws of human groups.
3, the next generation of human-computer interface design is an integrated approach to interaction. It will make extensive use of speech, natural language and high-level graphics, but also other interactive media can be used, but also three-dimensional images can be used to vividly guide the interpretation of the interaction and the task. In conclusion, the future of human-computer interface design poses a multifaceted challenge to researchers and designers.
The following are the future development trends of human-computer interface:
1. Natural interface: Natural interface refers to the use of natural scenes or life scenes for human-computer interaction. For example, air control equipment with virtual display, intelligent car equipment with breath-sensitive control system, etc. 2.
2. virtual reality technology: with the development of virtual reality technology, the human-computer interface gradually develops a new type of interactive interface, that is, people interact with computers through the 3D virtual environment, and its application involves virtual reality games, medical treatment, education and other aspects.
3. voice interaction: voice recognition technology has gradually entered people's lives, intelligent devices and products equipped with voice recognition technology are common, and daily life can also be controlled by voice interaction in smart home, smart car, etc.
4. Gesture Interaction: With the progress of gesture recognition technology, it will become another new trend of human-machine interface, realizing the control of human-machine interface through special gestures, which will be widely used in the fields of family entertainment, city management, medical care and so on.
5. Networking and Interoperability: With the development of Internet technology, HMI will also tend to be standardized and interoperable, which will help to ensure the stability and performance of the system while enhancing the human-machine interaction.
All in all, the future development trend of HMI not only involves the improvement of people's operation skills and experience, but also involves the diversification of forms, scenarios and venues, which means that the HMI technology is constantly changing and innovating while constantly being put into practice.
