First of all, we must understand the classification of VR system.
0 1
Non-immersive virtual reality system, in which users interact with virtual environment through keyboard, mouse, joystick or touch screen, is usually called non-immersive VR system, also known as desktop or window virtual reality system.
Non-immersive virtual reality is becoming more and more popular in modern education, because it can provide real-time visualization and interaction in a virtual world very similar to the real world, which is helpful to improve the efficiency of teaching activities. At the same time, the desktop VR is barrier-free, and students can complete the experiment on PC or mobile terminal, which is not limited by time and space.
02
Immersive VR system can make users fully integrate into and perceive the virtual environment and gain a sense of existence. Generally, there are two ways to realize system functions: CAVE automatic virtual environment (CAVE for short) and head-mounted display, and equipped with motion sensors to assist natural interaction.
Some scholars have found that immersive virtual reality can make users have better memory ability than non-immersive virtual reality. Their latest research on 20 19 shows that users pay more attention to the additional tasks of deep immersion experience, and the sense of space is very important for users' memory. However, immersive VR requires high terminal use, interactive experience and software quality, and is not suitable for most teaching subjects at this stage.
03
Distributed virtual reality system enables users from many places to interact in real time and share the same virtual world through the Internet. Virtual worlds do not exist independently, but run on multiple computer systems connected by networks. Some scholars believe that distributed virtual reality system is widely used in the field of education, which is convenient for long-distance multi-person learning.
Distributed VR system is helpful to cultivate students' team consciousness and help students understand the function of multi-role division of labor and cooperation, but it requires higher network environment of clients and data processing ability of servers.
The Application Theme of Desktop Virtual Reality System
Focus on cultivating students' ability to discover, analyze and solve problems. Students can master relevant knowledge points and skills through repeated operation training of experimental subjects. Such as circuit fault diagnosis, elderly care and other subjects.
Application theme of immersive virtual reality system
There is a high demand for immersion, such as driving skills, interior design and other subjects. Pay attention to deepening students' sensory experience of knowledge content, enhance students' memory of knowledge content through immersion and stimulate students' creative thinking.
The Application Theme of Distributed Virtual Reality System
Pay attention to cultivating students' teamwork ability, and deepen students' cognition and understanding of systematic knowledge, such as medical surgery, economic experiments and other disciplines.
Applying VR/ virtual reality technology to education classroom is a new teaching mode, which has certain advantages and disadvantages. Here are some advantages and disadvantages that you may want to consider.
Advantages:?
1. It provides a more interactive learning experience: through VR technology, students can interact in the virtual environment and participate in the learning process, thus better absorbing knowledge.
2. Enhance the realism of learning: VR technology can create realistic virtual scenes, help students to understand concepts more deeply and enhance their memory of knowledge.
3. Provide richer learning resources: VR technology can provide students with richer learning resources. For example, students can conduct experiments in a virtual laboratory without using real experimental equipment.
4. Cultivate students' creativity: VR technology can stimulate students' creativity, because they can freely explore and put forward new ideas in a virtual environment.
Disadvantages:
1. High cost: Using VR technology requires purchasing and maintaining special equipment and software, which will bring high cost.
2. High technical threshold: VR technology may be difficult for some students and teachers to master, and it takes time to learn and adapt.
3. It is easy to cause motion sickness: For some people, long-term activities in the virtual environment may lead to motion sickness or other physical discomfort.
4. Some disciplines are difficult to apply: Some disciplines may be difficult to apply VR technology, such as studying history or literature, which is not suitable for learning in a virtual environment.
Applying VR technology to education classroom has some obvious advantages, but it also has some disadvantages. Therefore, the use of VR technology needs to carefully consider its applicability and practicality, and choose according to the actual situation.
The application of VR technology makes "learning by doing" a reality anytime and anywhere.
