Evolution of Media Presentation Technology
Before we start talking about VR, let's take a look at media presentation technology. The evolution of surgery actually has a lot to do with VR and education. Historically, the evolution of media began with words, which is the earliest form of recordable media and belongs to a single media form, and has been widely used until now. The second form is composite media, including more than two forms of media technology. We often use audio-visual media, similar to early movies. The third media form is interactive composite media, such as multimedia technology, which is an interactive composite media produced by combining audio-visual technology after the invention of computers, and this media has been recognized and used by everyone for decades.
What kind of media form will appear after multimedia technology? Me? Scientists think it is virtual reality, that is, virtual reality, referred to as VR. VR is a highly immersive media form with a strong sense of immersion. What is immersion? Generally speaking, after wearing virtual equipment (virtual glasses, virtual helmet, etc.). ), we seem to have entered another world, giving users an immersive experience.
In the evolution of media presentation technology, each new media? The presentation form has made great progress compared with the previous media form. The emergence of VR may be an epoch-making product. This is a revolutionary node of media presentation technology, which will have a fundamental impact on all industries involved in media presentation.
Is there an education-related VR application developed by an American company? Education VR. Through an electronic pen, a pair of 3D glasses and a special computer, the 3D effect of human skeleton structure can be displayed, giving people a very realistic learning experience. This means that VR is a revolutionary media because it can present a very real "reality".
The picture shows the panoramic VR vision jointly launched by New Oriental and LeTV. Frequency teaching. After wearing 3D glasses, you will feel like you are in a classroom. Turn your head or look up or down, and the scene will change accordingly, which will bring a very realistic experience to the whole English teaching. In addition, there are other aspects of virtual teaching. As shown in Figure 4, in the field of medical teaching, using VR technology to present human body structure, learners can understand the appearance of human body structure more intuitively and clearly.
The application of VR in education is still in its infancy.
The emergence of VR has been several decades, and VR was first used? In the military field, it is used to realize military simulation of combat, flight and other tasks. With the development of the times, the application of VR in other industries has gradually expanded.
For example, the game entertainment industry uses the highly immersive field presented by VR? The scene is incomparable with current 3D movies and 3D games. In the field of architecture, VR equipment can be used to plan residential buildings and environment in an immersive way. In the field of industrial manufacturing, VR can be used to simulate equipment. In the medical field, VR plays a very important role in the presentation of medical knowledge.
As we all know, VR is very popular now, in games, movies and entertainment? Music is widely used, and the commercial application is earlier than the education industry. Now our educational application has begun to sprout. For example, in the virtual laboratory, students can conduct experiments by operating virtual experimental equipment to avoid potential safety hazards caused by dangerous chemicals, and at the same time, they can conduct experiments for many times, so that students can understand chemical principles more deeply and vividly. Another example is a virtual historical scene. VR technology can be used to create a virtual historical event scene, in which students seem to be witnesses of history or even witnesses. There is also virtual training, such as car maintenance. The installation and maintenance of various equipment can be trained through VR equipment.
How will the application of VR in the field of education develop?
1. Overview of the development cycle of mobile learning
A summary of the historical development cycle of mobile learning
Many people hold different views on the application of VR in education. ? Reviewing the development cycle of mobile learning will help us to judge the application cycle of VR in the education industry.
In fact, around 2007, mobile learning has sprouted. As a device, the release of iPhone is a revolutionary impact on mobile learning. Since the appearance of Apple devices in 2007, there have been many educational applications. However, after 2009, mobile learning is still in a relatively early introduction stage. It was not until 20 12 and 20 13 that mobile learning really broke out with the further popularization of Apple devices. In other words, after five or six years, when the iPhone became very popular, the whole concept and feasibility of mobile learning were greatly satisfied. With the increasing installed capacity, mobile learning has entered a very strong outbreak period.
2. Life cycle analysis of educational virtual reality.
The development cycle of mobile learning is also very suitable for VR education. ? There are several factors for a technology from germination to popularization: first, the experience effect. For example, early mobile learning, due to poor experience, has been stagnant, and it was not until the emergence of Apple devices that it was widely popularized. The second is the penetration rate of equipment. Now VR is considered to be very good, but its application in education is still very few. However, as long as the equipment is popularized to a certain extent, the quantity and quality of VR educational applications will be greatly improved. Many tools and talents have been developed for this purpose. At this time, the application will break out and the user's usage habits will begin to develop. In addition, the market development process of a product is also closely related to the promotion of capital. The greater the capital impetus, the shorter the maturity period. Fig. 8 is a prediction diagram of the development cycle of VR education.

20 16 is called the first year of VR, just as 20 13 is considered to be in? The same is true for the first year of online education. In fact, in China, online education sprouted at 1996, but it didn't start until 20 13. Similarly, 20 16 is the explosive period of VR investment, not the explosive period of application. Now a large amount of investment will accelerate its development.
We believe that more VR hardware products will come out in 20 17 years. The hardware structure will be formed in the next few years. From 20 18, VR applications will explode, and the development cycle of VR applications will be greatly shortened with the help of capital. 2065 438+08-2065 438+09, VR hardware will tend to be stable, and a large number of VR educational applications will be born. 20 18 when VR applications enter the explosive period, the hardware will become very popular, and the developed interface technology will also form a standard. In 20 19 years, VR education may enter the mature stage of application. The maturity of VR education application will attract a large number of learners, and at the same time, it will be integrated into the business model, and the user experience will be very good.
To sum up, in the next two or three years, after a lot of market information? The injection of capital will produce a lot of bubbles and make the industry mature. Then around 2020, the popularity of VR will enter the civil period as we use smart phones now. The author predicts that VR education will have such a development cycle.
What kind of subject field is suitable for VR?
Many people pay attention to the application of VR in the education industry. What is it like? Can VR be applied? We believe that VR is more suitable for natural, scientific and engineering disciplines. In addition, language, culture and human history can be applied. For example, biology, physics and chemistry, as well as basic disciplines such as technology processing, engineering technology and flight driving, as well as some visual scenes such as history, humanities, language learning and cultural narrative. In short, any subject with visual characteristics can be presented by VR. On the other hand, content that is difficult to visualize is not suitable for using VR. For example, some very abstract concepts, logic, and some mathematical concepts are difficult to express with VR.
VR is indeed an epoch-making media technology. What can it bring? High-quality learning experience. From the development of human learning technology, it has revolutionary characteristics. Although VR is still in its infancy, there are many problems, such as dizziness when wearing a VR helmet, poor interactivity and unclear image quality. However, with the continuous progress of VR technology, these problems will be effectively solved in the future.
In the past five years, the Internet has brought many surprises to the education industry. Learning experience anytime and anywhere, cross-regional sharing of high-quality educational resources, let society enter the era of learning for all. However, Internet education also encounters many problems, such as the loneliness of learning caused by the separation of teachers and students, and the persistence of learners' autonomous learning is not strong. The emergence of highly immersive media presentation technology represented by VR has brought unprecedented high-quality learning experience to learners, and it is also expected to solve the unsolved problems in Internet education. China Augmented Reality Industry Alliance referred to as AR Alliance or ARA believes that VR will work with the Internet to jointly promote the development of modern education.
