Design And Implementation Of Virtual Experiment Based On Immersive Virtual Reality Technology

With the rapid development of information technology,virtual reality is developed to the immersive virtual reality stage from computer simulation stage.This undoubtedly provides lots of technical supports for virtual reality in education.Based on this chance,this study is targeted at a series of problems in traditional experimental teaching environment of Computer Hardware Assembly in secondary vocational schools,including slow experimental equipment updating,large hardware loss,and safety loopholes in experimental process.The author designs and develops the immersive virtual experiment,realizes the core functions of hardware introduction,virtual scene roaming,simulation assembly hardware,and exercise test,and proposes a new approach to improve the traditional experimental teaching environment and teaching effect.The main research contents of this thesis include the following aspects:(1)Constructivism learning theory,autonomic learning theory,immersive theory and “cone of experience” theory are used as theoretical bases of the immersive virtual experiment teaching content design to guide development of computer hardware assembly virtual experiment.Also,the author elaborates and conducts advantages for key technology and relevant equipment used in the development process.(2)On the basis of analyzing application advantages of learner analysis,teaching goal analysis,feasibility analysis,demand analysis,immersive virtual experiment in education analysis,and Cognitive mechanism analysis,the author completes teaching content of immersive virtual experiment,interactive mode,operational mode,teaching evaluation,immersive realization element design of virtual experiment,functional module design,3D model and virtual scene design.(3)The author uses 3Ds Max and Unity3 d software to create 3D model and construct the virtual experiment scene.Mojing SDK is used as the virtual experiment display effect and interactive interface tool,combines with the head-mounted display and somatosensory handle to effectively overcome shortcomings of virtual experiment based on Virtools technology,and greatly improves immersion and interaction of virtual experiment to enhance students' learning interest.(4)The author completes the development of immersive virtual experiment application based on the mobile client,including menu module,basic learning module,virtual experiment module and experimental feedback module,conducts a system test for teaching content presentation,system operation stability and delay,and ensures stability of system operation.At last,the actual use effect and interview have gotten the good feedback results.
