1. Education field
Allowing students to learn to return to the scene and participate in interactive virtual reality has three major characteristics: interactivity, immersion, and imagination.
The traditional education method acquires knowledge through pictures and texts printed in books and multimedia displays in the classroom. This way of learning gradually becomes tiring after a while, and the learning effect is poor. However, students who have played League of Legends all know why this game is so attractive. The essence is to return to the scene and participate in the process.
Virtual reality technology can clearly express things in three-dimensional space, allowing learners to interact directly and naturally with various objects in the virtual environment. And participate in the development and change process of events through various forms, so as to gain the greatest degree of freedom to control and operate the entire environment. This virtual learning and training environment that presents multi-dimensional information will provide the most intuitive and effective way for learners to master new knowledge and skills. It has obvious advantages and characteristics in many education and training fields, such as virtual laboratories, three-dimensional concepts, ecological teaching, special education, simulation experiments, and training in professional fields. For example, when students learn the composition, structure, and working principles of a certain mechanical device, such as a water turbine engine, traditional teaching methods use diagrams or videos to show students. However, this method is difficult for students to have a clear understanding of the operating process, status, and internal principles of this device. Virtual reality technology can fully demonstrate its advantages: it can not only intuitively show students the complex structure, working principle and operating status of each component during operation, but can also imitate the operation of each component during production. It provides students with simulation training opportunities to comprehensively inspect, manipulate and even repair virtual things by analyzing the performance and causes of faults, thereby achieving twice the result with half the effort in teaching and experimentation.
2. Military field
In the military, the latest technological achievements of virtual reality are often first used in aerospace and military training. Virtual reality technology can be used to simulate the control and training of new weapons such as aircraft to replace dangerous actual operations. Using virtual reality to simulate the actual environment, large-scale military internship simulations can be carried out in a virtual or simulated environment. The virtual reality simulation scene is just like a real battlefield, and operators can experience the real feeling of attacking and being attacked. This will facilitate a smooth transition from virtual weapons and battlefields to real weapons and battlefield environments, and its impact on various military activities will be extremely far-reaching and broad military application prospects. To date, virtual reality technology is playing an increasingly important role in the military.
3. Industrial field
Virtual reality has been widely used in industrial fields. For the automotive industry, virtual reality technology is not only the latest technology development method, but also a complex simulation tool. It aims to establish an artificial environment in which people can engage in real-time activities such as driving, operating and designing in a natural way. And virtual reality technology can also be widely used in automotive design, experiments, and training. For example, a three-dimensional car model established with the help of virtual reality technology in product design can display the car's suspension, chassis, interior, and even each welding point. Designers can determine the quality of each component and understand the operating performance of each component. This three-dimensional model is so accurate that car manufacturers can directly proceed with mass production based on the computer data obtained. Virtual reality technology also has a large number of applications in CAD, technical education and training and other fields. In the construction industry, virtual reality can serve as a further extension of well-produced architectural renderings. It can form an interactive three-dimensional architectural scene. People can walk freely in the building and operate and control the equipment and room decoration in the building. On the one hand, designers can understand from the perception of the scene, Discover design deficiencies; on the other hand, users can feel the real architectural space in the virtual environment and make their own judgments.
4. Art and Entertainment
Since the requirements for virtual reality in entertainment are not too high, VR has developed the fastest in this area in recent years. As a carrier for displaying information, the potential application capabilities of VR in the future art field cannot be underestimated. The on-site participation and interactive capabilities of VR can transform static art (such as oil paintings, sculptures, etc.) into dynamic ones, allowing viewers to better appreciate the author's art.
5. Medical treatment
In terms of medical education and training, doctors have limited opportunities to train and practice complex surgeries, but in the VR system, they can practice different operations repeatedly. VR technology will enable repeated and very realistic practice of operations that are dangerous, cannot make mistakes, but have little or no real practice. At present, many foreign hospitals and medical schools have begun to use digital models to train surgeons. The method is to combine information obtained by X-ray scanning, ultrasonic detection, nuclear magnetic resonance and other methods to establish a simulation model that is very close to the real human body and organs.
6. Urban simulation
Due to the high relevance and forward-looking requirements of urban planning, urban planning has always been one of the fields with an urgent need for new visualization technology. From master planning to urban design, at each stage of planning, through the description of the current situation and the future (immersive urban experience, real-time landscape analysis, building height control, multi-plan urban space comparison, etc.), it provides strong support for improving the living environment and forming unique urban styles. Planning decision-makers, planning designers, urban construction managers and the public play different roles in urban planning. Effective cooperation is the prerequisite to ensure the ultimate success of urban planning. VR technology provides the most ideal bridge for this kind of cooperation. The use of VR technology can enable government planning departments, project developers, engineering personnel and the public to interact in real time and truly see the planning effects from any angle, better grasp the shape of the city and understand the planner's design intentions. In this way, the macro-decision-making of decision-makers will become a more organic part of urban planning, and public participation can be truly realized. This is something that traditional means such as floor plans, renderings, sand tables and even animations cannot achieve.
7. Scientific Computing Visualization
In scientific research, people will always encounter a large amount of random data. In order to obtain valuable patterns and conclusions, these data need to be analyzed. The scientific visualization function converts a large amount of alphabetical and numerical data into visual images that are easier to understand than the original data, and allows participants to check these "visible" data with the help of visual virtual devices. It is often used to build digital models of molecular structures, earthquakes, and various components of the Earth's environment.
There are certain differences between scientific computing visualization supported by VR technology and traditional data simulation. For example, in order to design a wing with low resistance, people must analyze the aerodynamic characteristics of the wing. Therefore, people invented the wind tunnel test method. By using smoke gas, people can directly observe the interaction between the gas and the wing with the naked eye, thus greatly improving people's understanding of the dynamic characteristics of the wing. The purpose of the virtual wind tunnel is to allow engineers to analyze the complex three-dimensional properties and effects of multi-vortices, air circulation areas, turbulence when vortices are destroyed, etc. However, these analyzes are difficult to visualize using usual data simulations.
