Application of AUGMENTED reality in education - Dr
At present, the contradiction between the people's ever-growing material and cultural needs and backward social productive forces has encouraged the rapid development of new and high technologies and accelerated their renewal. For electronic products, people prefer portable handheld devices with diversified functions. In the field of family education, many parents have begun to choose more convenient mobile phone directional software instead of traditional books and videos. This transformation means that children's education will gradually enter a new stage of development.
Augmented Reality technology (AR for short) applies virtual information to the real world, so that the real environment and virtual objects are superimposed on the same screen or space in real time, and the interaction between the virtual world and the real world is realized at the same time. Studies in recent years have found that the application of this technology in the field of children's education can produce good educational/teaching effects, and it has become an important tool to assist the development of children's education. Children's education mode integrating augmented reality technology changes the single feeling teaching, pays more attention to children's listening, speaking, reading, writing and other all-round immersive sensory experience, retain their playful nature, make boring learning become full of fun, enjoy learning, happy learning.
First, the concept of augmented reality technology
On the face of it, augmented reality is an on-the-spot feeling of reality. At present, the development and application prospects of this technology are optimistic about the relevant research institutions and companies around the world. Augmented reality (AR) technology is a comprehensive technology that relies on computer graphics technology and visualization technology, trying to create advanced experience that integrates virtual and reality. The working principle of this technology is relatively complex. In simple terms, virtual things are placed in the real environment through sensing technology, so that users can directly interact with virtual objects in the real space. With the rapid development of relevant high and new technologies, the combination of augmented reality technology and augmented reality technology has spawned new products with important value and significance, which have been applied in many fields and achieved good results. According to the current situation, the potential market and value of this new product based on this technology are quite large. The most significant three features of this technology are as follows :(1) it can achieve seamless integration between real and virtual; (2) Participating users can get a real sense of interactive experience; (3) The idea of overlaying virtual objects in a real environment becomes a reality. Looking at the application status of augmented reality technology at home and abroad, several application platforms have started this new service, and the technology is moving steadily on the road of white-hot.
Second, the bottleneck of augmented reality products
Currently, there are three main categories of ar products on the market. The first is head-mounted AR display, which is the most common product at present. This kind of products are mainly used in industry, medical treatment, education and other fields. The second type, hand-held AR display equipment. The biggest advantage of this kind of device is its convenience, the application field basically concentrates on business, game, education and so on. Third, desktop AR display. This kind of equipment is generally used for large space occasions, suitable for press conferences, venues to carry out activities.
For the field of children's education, the handheld/portable AR display device has a broad application prospect. Especially at present, when the overall fertility level and fertility willingness of the society are low, parents prefer to give their children better education. However, most parents in the professional curriculum knowledge reserve and parenting time, more or less there are difficulties. Portable AR display device, can let children at any time and anywhere on-the-spot perceptual learning. To some extent, it can reduce parents' worries about their children's learning and improve the possibility of their children's efficient learning outside the classroom.
At present, most children's education products based on augmented reality technology focus on cognitive level, using the mode of "scanning cards and displaying information" to help children strengthen their cognition of specific things or knowledge points. In general, the biggest disadvantage of such products is that the learning content is too simple and reduces children's sense of participation. In addition, the research and development process did not fully consider the cognitive rules of children of all ages. For example, at the age of three, children over three can no longer rely on simple demonstration teaching to enhance their cognitive abilities, and children under three are not physically able to use augmented reality products. Although great progress has been made in the research and development, promotion and application of such products, there are still many problems, including the above problems, which need further research.
The application of augmented reality technology in children's education
An excellent augmented reality educational product for children is bound to be centered on the Guidelines for Kindergarten Education (Trial), and fully demonstrate the value and significance of augmented reality technology. The learning content of the product is differentiated for children of different ages, but the learning content of each stage should include health, language, society, science and art, etc. The application of the product fully considers the characteristics of children, which can not only satisfy the curiosity of children, but also closely follow the basic purpose of the product education, so as not to ignore their thirst for knowledge.
For all stages of children's education, both the education environment and the education content must follow the principle of diversity and interest, so as to achieve the effect of efficient education. For example, a product called "Augmented reality Bear Exploration Series bear Cake" is a relatively successful case that is loved by a large number of consumers. If the product is divided according to the type, it belongs to the class scientific reading material, with the characteristics of accuracy, authority and science. The whole process of product development is independently completed by the company's internal staff, which is an original augmented reality product. The operation form of this product is mobile terminal device, that is to say, no matter mobile phone or tablet computer can be relatively convenient to complete the operation. This product design and research and development target population is for preschool children, specifically 4 to 6 years old children, the product in the design process strictly in accordance with the general characteristics of the age of children. In the process of use, school-age children can follow the character of cartoon bear, achieve the goal in the game to get a sense of achievement, and experience the happiness of learning. In the process of research and development, the product pays attention to the integration of sound effects, animation, video, interactive sections and many other elements, trying to provide more real and interesting experience for children receiving education. The content of the product refers to the cognitive rules of children, and the knowledge of mathematics, Chinese and English that comprehensive kindergarten will soon be upgraded to primary school should master. When the product completes the educational function, it attaches importance to the concept of time and space, and creates a unique logical thinking game, so that school-age children can learn happily in the game.
Iv. Building of children's education product platform system based on augmented reality technology
The essence of augmented reality technology is to complete the process of combining the virtual and the real. A mature augmented reality educational product for children should not only meet the rigid needs of high-quality hardware, but also have a unique and perfect software system. Only with both hardware and software can you create a more realistic and effective user experience. Therefore, children's education products of augmented reality should pay attention to each part at the beginning of design. The hardware part mainly has five systems, which are video display system, computer system, human-computer interaction system, sensing system and motion capture tracking system. The software part includes several modules, including 3d model module, platform development module, image recognition module and interactive operation module. At the heart of the platform are real graphics and image recognition and three-dimensional technology, both of which rely on electronics.
For example, cameras are an essential component of handheld devices, and their penetration and compatibility are guaranteed to a certain extent. Camera can capture a certain range of dynamic data and related instructions received from the operator, at this time all relevant information is transferred in the shortest possible time to be processed in the computer system, and then output the effective information through real-time display on the LCD screen display equipment, formed a relatively complete the actual interaction process.
5. Upgrading and innovation of augmented reality technology
A successful augmented reality education product for children usually focuses on children's school-age stage, so that the learning content of the product is clearly organized and easy to learn. Augmented reality products focus primarily on the user's sense of experience. For children's education, immersive experience is the most applicable and effective. A good product based on augmented reality technology can provide an opportunity for them to learn in the games they are interested in, which can not only solve the problem of children's concentration difficulty, but also fundamentally improve the efficiency and depth of learning. The learning process takes the game as the carrier, and at the same time sets up virtual and real interaction functions, such as allowing children to interact with virtual characters and complete learning tasks with virtual characters in the game. The interactive section should be designed to be easy to understand and allow children to operate independently. The path of technological upgrading and innovation cannot be divorced from the original intention of people-oriented education; In addition, the importance of individualized education should be explored to make children's education flexible and efficient.
Six, the summary
In general, the application of augmented reality technology in the field of children's education is the achievement of The Times. As one of the benchmark tools for the development of science and technology in the new era, augmented reality technology can not only change and supplement the traditional education model, but also fundamentally improve the experience and interest of education. Up to now, augmented reality children's education products have great market potential, which is a rare opportunity given by The Times for relevant development units. The subsequent research and development needs to accurately grasp the applicable group of children and combine the characteristics of the group to maximize the significance and value of the technology.
