Just like a computer talking to people through 1 Monitor 2 speakers; People talk to the computer through 1, keyboard 2, mouse.
CNC machine tools and people are displayed on the screen and numbers through 1. 2. Alarm sound,,, through the input keyboard,,, shows people and machines.
Just the technology in this field.
Question 2: Compared with the traditional user interface, the most important change of the multimedia user interface after the introduction of video and audio is that the interface is no longer a static interface, but a time-varying media interface related to time. Humans use language and other time-varying media (such as gestures) in a completely different way from other media. In terms of information presented to users, time-varying media are mainly presented in sequence, while visual media (words and graphics) that we are familiar with at ordinary times are usually presented at the same time. In the traditional static interface, users either choose from a series of options (explicit interface communication component) or interact in a recognizable way (implicit interface communication component). In the user interface of time-varying media, all options and files must be presented in order. Due to the limitation of media bandwidth and people's attention, in time-varying media, users should not only control the content of information presented, but also control when and how to present it. The characteristics of human-computer interaction in VR system can be said to be the core of VR system. Therefore, the characteristics of human-computer interaction in VR system are the basis of all software and hardware design. Its characteristics are as follows: the viewpoint is the starting point of user observation. Navigation refers to the user's ability to change the observation point. Manipulation refers to the user's ability to act on the surrounding objects. Immersion refers to the user's immersive feeling, which is becoming more and more important in VR system. If the human-computer interaction in VR system wants to have these characteristics, it needs to develop new interactive equipment, including three-dimensional spatial positioning equipment, language understanding, visual tracking, head tracking, gesture recognition and so on. The human-computer interaction between multimedia and virtual reality system has some common characteristics. First of all, they all use multiple sensory channels, such as vision and hearing; Secondly, they are all time-varying media.
Question 3: What is human-computer interaction technology? Man-machine interaction technology refers to the technology of realizing the dialogue between man and computer in an effective way through computer input and output equipment. It includes that the machine provides a large amount of relevant information and prompts instructions to people through output or display devices, people input relevant information and prompts instructions to the machine through input devices, and people input relevant information and answer questions to the machine through input devices. Man-machine interaction technology is one of the important contents of computer user interface design. It is closely related to cognitive science, ergonomics, psychology and other disciplines.
Question 4: Introduction of human-computer interaction technology Human-computer interaction technology refers to the technology of realizing the dialogue between people and computers in an effective way through computer input and output devices.
Question 5: What does human-computer interaction mean? Human-computer interaction system (HCI) refers to the human-computer interaction system, which is a technical science that studies the communication between people and computers through mutual understanding, completes the functions of information management, service and processing for people to the greatest extent, and makes computers truly become harmonious assistants for people's work and study.
Man-machine interaction system is developed with the birth of computer. In modern and future society, as long as someone uses information processing technologies such as communication and computer to carry out activities for society, economy, environment and resources, human-computer interaction is an eternal theme. In view of its importance to the development of science and technology, it is the highest goal of modern information technology and artificial intelligence technology to study how to realize natural, convenient and ubiquitous human-computer interaction. It is also a new intersection of mathematics, information science, intelligent science, neuroscience, physiology and psychology, and will guide the hot direction of information and computer research at the beginning of 2 1 century.
Question 6: What is human-computer interaction? What are the common ways of human-computer interaction?
Question 7: What are the main technologies of human-computer interaction in virtual reality? Aiming at the demand of virtual substation training system, the man-machine interaction mode is studied. It mainly provides the functions of using a two-dimensional interactive device (mouse) to manipulate the selection, translation and rotation of objects in a three-dimensional space in a scene. Theoretically, these functions are accomplished by the principle of geometric transformation of objects in three-dimensional space of computer graphics. So as to realize the basic human-computer interaction operation in the virtual scene. In order to simulate the physical characteristics of real people walking, a virtual person is designed to control the viewpoint. The virtual substation training system developed by using the virtual reality environment of super cape VRT is used to simulate the real world with virtual reality, so as to overcome the limitations of the real environment (such as inconvenient operation, danger, unreachable, remote and occlusion). ), reduce the psychological burden of operators and reduce operational errors.
Question 8: Research and development of intelligent human-computer interaction technology. Which companies' geographic information systems are computer systems that collect, store, manage, analyze, describe and apply data related to the spatial and geographical distribution of all or part of the earth's surface (including the atmosphere) (1997 reference)? It consists of hardware, software, data and users. Its main function is to realize the collection, editing, management, analysis, statistics and mapping of geospatial data, and the tools have been gradually developed.
GIS began in Canada and the United States in the 1960s, and then many countries put in a lot of research work. Since the late 1980s, especially with the rapid development of computer technology, geographic information processing and analysis methods have become increasingly advanced, and GIS technology has become increasingly mature, which has been widely used in the fields of environment, resources, oil, electricity, land, transportation, public security, first aid, aviation, municipal management, urban planning, economic consultation and disaster loss prediction.
However, with the rapid development of information technology, especially computer technology, the proposal and implementation of digital earth, and the deepening and broadening of the application depth of geographic information system, geographic information system is experiencing rapid changes and development, which puts forward many new requirements for geographic information system. On the one hand, the progress of computers and technological breakthroughs such as the development and utilization of information networks make it easier to express information in digital form. On the other hand, geographic information still lags behind other information that is more suitable for digital forms, such as numbers and texts. Therefore, there are some difficulties and obstacles in the use of geographic information. If these obstacles can be properly solved, the application of GIS will develop by leaps and bounds. This paper introduces, analyzes and summarizes the hot issues of current geographic information system.
The influence of computer technology on the development trend of geographic information system
The main tools and platforms supported by GIS technology are computers and related equipment. Since the 1990s, with the development of computer technology, the processing speed of computer microprocessors is getting faster and faster, and the cost performance is getting higher and higher. Its memory can realize the ability of mapping large files to memory, and can store massive data. In addition, with the breakthrough progress of multimedia technology, space technology, virtual reality, digital mapping technology, data warehouse technology, computer graphics technology, three-dimensional graphics chip, large-capacity optical disk technology and broadband optical fiber communication technology, especially the establishment of satellite internet has eliminated the bottleneck of data communication, and a large number of high-resolution, hyperspectral and short-period remote sensing satellites can provide real-time earth observation images, which have shown a brighter prospect for the extensive and in-depth application of GIS technology. At the same time, the current GIS can no longer meet the requirements of the information age and the digital age. At present, GIS mainly presents the development trends of networking [1][3], openness [5], virtual reality [1], integration [2] and spatial multi-dimension [4][6].

It not only supports data flow within the application system, but also supports data flow between systems. Open GIS is to make different >>
Question 9: What are the human-computer interaction systems? With the continuous development of information technology, computers have penetrated into all fields of society, and people have entered the information age with computers as the main means of study, work and life. At present, students of any major in any university have to learn computer knowledge more or less.
With the popularization of computer knowledge, some students and parents think that computers are just tools to assist people in other jobs. Since any major in the university should learn to use computers, it seems unnecessary to study computers as a major. In fact, this is a misunderstanding of the computer major, which is caused by the lack of understanding of the training objectives and learning content of the computer major.
For example, maybe in the near future, everyone will use cars as a means of transportation, and everyone will drive cars, but certainly not everyone will study and design cars. Only people who study cars can do such a job. The same is true for computer majors. Everyone can use computers, but the research and design of computers can only be undertaken by computer professionals.
Non-computer majors receive popular computer education with the purpose of application. Computer students receive professional computer education. The purpose of training students in computer specialty is not to make them proficient in using computers, but to make them master the solid theoretical foundation of computers, learn advanced computer design and development technologies, and become professionals with good comprehensive quality, strong innovation ability and strong practical ability.
There are essential differences between the training scheme and curriculum system of computer major and computer teaching of non-computer major. First of all, students majoring in computer science must master a solid theoretical foundation and learn the mathematical basis of computer science, such as discrete mathematics, probability and mathematical statistics, formal language and automata, theoretical computer science and so on. These basic theories are often not systematically studied by non-computer majors. Without these theoretical knowledge, it is impossible to engage in theoretical computer science research in the future, such as computability theory, algorithm design and complexity analysis, cryptography and information security, distributed computing theory, parallel computing theory, network theory, bioinformatics computing, computational geometry, programming language theory and so on.
Secondly, students majoring in computer science must have systematic professional knowledge and learn a large number of professional basic courses and specialized courses, such as programming foundation, digital logic circuit, computer composition principle, operating system, data structure, compilation principle, network principle, software engineering and so on. Through these courses, students can deeply understand the hardware composition and structure of computers and master comprehensive software design and development techniques. The learning process emphasizes the combination of basic theory and practical application, and cultivates innovative ability in learning and practice. Non-computer majors generally only learn basic programming, simple operating system and network application, which are not comparable to computer majors in depth and breadth.
Thirdly, students majoring in computer science can also have a lot of opportunities to learn professional elective courses that reflect the frontier knowledge of computer science, such as database technology, artificial intelligence technology, multimedia technology, network security technology and so on. Through these courses, we can connect with the world's leading science and technology, broaden students' horizons, broaden their knowledge, and strive to cultivate students into compound talents suitable for research, design and application development. Non-computer majors often lack this opportunity to understand the frontier of computer science and technology, and all they learn are some mature basic computer knowledge, which is not challenging.
It is not difficult to see from the training scheme and curriculum system of computer major that students majoring in computer are not learning to use computers as a tool in the future, but using their own professional knowledge to enable users who use computers as tools to use computers more quickly, conveniently, effectively and safely.
Computer performance is always the most important aspect in computer design. There is still a big gap between China and the international advanced level in CPU design and implementation technology. It is the responsibility of computer graduates to design computers with faster calculation speed, stronger processing ability and more reasonable system structure. The basic requirements for undertaking this responsibility are to master a solid theoretical foundation of computer specialty, learn advanced design and development technology, and have extraordinary innovation ability, which can only be achieved through a series of professional course training. The average user only uses the computer through the operating system, not >>
