【摘要】：信息技术的快速发展推动着教学方式和新教学媒体的出现和运用,当前多媒体在教学中应用十分广泛时,教学技术更新速度极快,随之出现了虚拟现实技术这一新的教学媒体。虚拟现实技术即VR技术,这一技术是20世纪末兴起的一个具有综合性特征的信息技术,实现了多媒体技术、数字图像处理、传感器技术和计算机图形学等多项技术的融合。VR技术能够生成具有立体感的视觉和音效,由于人机交互是一种依靠自然技能且友好和谐的状态,而具有立体性的虚拟现实技术可以改变人机之间被动、枯燥的状态,这对于改善传统多媒体教学的现状将产生重要影响。虚拟现实技术可以实现多媒体教学的三维立体交互,构建一个看似虚拟,但境界逼真的多媒体教学环境。虚拟现实技术可以运用计算机来建立一个虚拟世界的系统,并进行体验,从而构成了一个计算机模拟的三维环境,即虚拟现实技术下的三维环境。这一虚拟的三维环境由计算机创建,并直接对计算机用户的视觉、听觉和触觉等感官产生影响,让人能够产生一种身临其境的感觉。随着虚拟现实技术的发展,当前其所涉及的范围很广,是一种集合了计算机技术、人工智能技术、图像处理、模式识别、语音音响处理、仿真技术等在内的集成技术。用户可以通过计算机进入到虚拟的环境之中,对环境中的对象进行操作与交互。本文将从教育技术学的角度对虚拟现实技术进行研究,将该技术作为一个新的教育技术,并在此基础上提出了教育技术学相关的新的研究领域——虚拟教学。虚拟教学一种将信息技术和现代人才培养管进行结合的新型教学手段,将人带入到一个虚拟空间内进行教学,虚拟教学主要利用虚拟现实技术,构建虚拟的学习环境,再将运用知识所产生的客观现实进行再现,从而将知识要点传授给学生,并引导学生运用自身的视觉和听觉等感官来接受虚拟环境中的信息,以此来提升学生对于学习的兴趣度以及自身的创新意识,引导学生积极发挥自身的想象力,提升创新思维。
[Abstract]:The rapid development of information technology promotes the emergence and application of teaching methods and new teaching media. At present, when multimedia is widely used in teaching, the speed of teaching technology renewal is very fast, and then virtual reality technology is a new teaching medium.Virtual reality technology is called VR technology, which is a kind of information technology with comprehensive characteristics that rose at the end of 20th century. It realizes multimedia technology and digital image processing.The fusion of sensor technology and computer graphics. VR technology can produce three-dimensional visual and sound effects, because human-computer interaction is a friendly and harmonious state based on natural skills.The three-dimensional virtual reality technology can change the passive and boring state between man and machine, which will have an important impact on improving the current situation of traditional multimedia teaching.Virtual reality technology can realize the three-dimensional interaction of multimedia teaching and construct a seemingly virtual but realistic multimedia teaching environment.Virtual reality technology can be used to build a virtual world system and experience, thus forming a computer simulation of three-dimensional environment, that is, virtual reality technology under the three-dimensional environment.This virtual three-dimensional environment is created by the computer and has a direct impact on the visual, auditory and tactile senses of computer users.With the development of virtual reality technology, it involves a wide range of technologies, which include computer technology, artificial intelligence technology, image processing, pattern recognition, speech sound processing, simulation technology and so on.The user can enter the virtual environment through the computer to operate and interact with the objects in the environment.In this paper, the virtual reality technology is studied from the point of view of educational technology, which is regarded as a new educational technology. On this basis, a new research field related to educational technology, virtual teaching, is put forward.Virtual teaching is a new teaching method which combines information technology with modern talent training, and brings people into a virtual space for teaching. Virtual teaching mainly uses virtual reality technology to construct virtual learning environment.Then the objective reality generated by the use of knowledge will be reproduced, thus the main points of knowledge will be imparted to the students, and the students will be guided to use their own senses such as vision and hearing to receive information in the virtual environment.In order to enhance students' interest in learning and their own innovative consciousness, to guide students to actively play their own imagination, improve innovative thinking.
