Introduction and application of virtual reality technology

Virtual Reality technology (English name: virtual reality, abbreviated as VR), also known as spiritual technology, is a brand-new practical technology developed in the 20th century. Virtual reality technology includes computer, electronic information and simulation technology, and its basic realization mode is computer simulation of virtual environment, thus giving people a sense of environmental immersion. With the continuous development of social productive forces and science and technology, there is an increasing demand for VR technology in all walks of life. VR technology has also made great progress and gradually become a new field of science and technology.

Methods/steps

Comprehensive application

(1) Realistic experiential teaching. The biggest advantage of VR virtual reality technology lies in the open and free teaching space, which solves the problems of classroom interaction, answering questions, hands-on practice and so on. For example, using VR professional simulation experience, let children experience gourmet chefs, office workers and convenience store clerks. Children not only need to finish their work as they do in real life, but more importantly, as a professional adventure simulation experience game, children will experience more confusion that is difficult to adapt in the future during the game, and children can also gain a lot of life insights during the game. At the same time, helmet-mounted VR equipment is applied to the teaching of children's courses. Teachers will arrange the courses before class, and the application of situational teaching content setting will bring immersive teaching experience to children. Learning is like watching a movie, which increases the fun of learning and supplements the teaching materials to some extent. For example, when it comes to going to the grassland, the virtual scene immediately switches to the grassland. Under the guidance of teachers, children can observe all kinds of animals on the grassland and communicate with teachers to effectively stimulate their interest in learning. They can also effectively create learning scenes, support cooperation, promote communication, and promote knowledge expression and application, thus effectively building a very good learning environment for children to learn more. In addition, VR virtual reality technology is a powerful tool to help teachers and students in the teaching process. Children can imitate the synchronous operation of the old teacher in class. When the teacher talks about the knowledge points, the students immediately start practical operation, and the hands, brain, eyes and ears are called synchronously to enhance knowledge memory, effectively improve learning efficiency, use more realistic audio-visual stimuli, improve children's attention, and train children's emergency response ability to disasters in simulation. For example, the United States uses VR to synchronize natural phenomena such as hurricanes and earthquakes into the daily teaching of kindergartens. In the process of children's simulation, traditional teaching elements such as graphics and data of slides are embedded into the virtual environment, so that children can be placed in real situations and make correct decisions quickly under nervous psychology, so that children can cope with security threats more calmly.

(2) Interactive concept teaching. VR virtual reality technology can combine mobile devices with APP software. Children's applications include video +AR, AR, 4D bookstore, hallucination, new photos and so on. In addition, there are many kinds of augmented reality books with supporting apps, such as: The Robot Ran Out, The Experiment Ran Out, The Dinosaur Competition Came, etc. The special display effect of augmented reality is achieved by superimposing virtual images on the real world through mobile phones. With the improvement of the performance of VR virtual reality technology and the reduction of its price, more educational investment companies will develop more colorful teaching resources, so that VR virtual reality technology can quickly enter kindergarten teaching classrooms and be widely used in daily teaching, thus subverting traditional educational methods and teaching forms, which has great application potential and prospects.

Application advantage

(1) Simulation and openness. VR virtual reality technology has broken the limitation of kindergarten teaching space. Teachers can conduct centralized teaching in any teaching environment. Teachers anywhere can enter the same virtual place for real-time centralized teaching through related network communication equipment.

(2) pertinence and autonomy. Compared with the daily teaching in kindergartens in reality, one advantage of VR virtual reality technology is that it can easily simulate any teaching subject. With the help of VR technology, children can be exposed to various complex learning environments, so as to carry out targeted training and improve their comprehensive processing ability and related processing skills. At the same time, with the help of its own virtual teaching system, children can spontaneously carry out repeated activities training for many times, so that children can always be in the leading position of teaching, master the initiative of training, and greatly improve the teaching effect.

(3) Safety and compensation. As the most important safety in kindergarten teaching, virtual environment is far safer than reality. Teachers and children can boldly try all kinds of training programs in the virtual environment. Even if a "catastrophe" is created, it will not cause "bad consequences", but it will be included in the training evaluation as a reference for the final teaching assessment. Under the condition of ensuring children's personal safety, teachers can unload the burden of hidden dangers in teaching activities and carry out as many kinds of training as possible, thus greatly improving children's skill level. At the same time, VR virtual reality technology also makes up for many aspects that traditional teaching cannot achieve. When expressing some three-dimensional knowledge, such as nature, weather, singing, music appreciation, color, theme decoration, etc., the three-dimensional display form will inevitably make the learning process more vivid and easier for children to accept and master. Applying VR virtual reality technology to kindergarten teaching has unparalleled advantages. It is undoubtedly a trend of kindergarten teaching to create a virtual training platform.
