Design And Implementation Of Interactive Teaching Platform Based On Virtual Reality Technology

The development of vocational education has become a vital part of China's current education field.Comprehensively improving the schooling level of vocational education and teaching quality has become an important measure to meet the new round of technological revolution and industrial transformation.Because the traditional teaching mode can no longer meet the needs of industry and enterprises for job ability,all higher vocational colleges should actively think about how to carry out teaching reform.Today,with the rapid development of science and technology,the use of information technology to implement teaching reform is undoubtedly the best choice.In order to speed up the process of teaching reform,an interactive online learning platform based on multimedia computer technology and network technology is constantly emerging.Although these teaching platforms have overcome the problem of uneven allocation of resources in time and space,and improved the teaching effect,they still can not meet the students' needs for experiment,practice and training.It is difficult to realize real-time interaction between teachers and students,and teachers are also unable to perform the functions of guidance and supervision.VR(Virtual Reality)can effectively solve the above drawbacks,but the hardware facilities of the existing VR system are very expensive,making it impossible to popularize in teaching.In this context,this thesis is based on VR for the design of interactive teaching platform.It mainly includes the following contents.Firstly,the history and development of VR technology are studied in detail,and the use of VR technology in different fields is summarized,focus on the analysis and collation of the current situation of VR technology in teaching at home and abroad,summarizing its advantages and disadvantages.This points the way for the design and implementation of the interactive VR interactive teaching platform.Secondly,it discusses the key technologies of virtual reality,introduces the relevant theoretical basis,and describes the current high degree of virtual reality equipment and its advantages and disadvantages for systematic analysis.From the perspective of instructional design,this thesis studies the design of human-computer interaction teaching process by using VR technology to develop learning scenes,introduces 3D modeling technology,model construction,picture text board production,video material production and virtual tour guide 3D scene.The principle of the design is to use 3dmax and Unity3 D engine to construct stereoscopic vision to construct a 3D view of the teaching needs,so as to design high quality pictures and video animation.From now on,introduce a simple interactive teaching platform formed by VR glasses(entry level),smart phone(android/ios),and Bluetooth wireless controller.The platform has low construction cost and wide coverage of students.It can also solve a series of problems such as shortage of teaching resources,lag of equipment conditions,aging of course content,and inability of teachers and students to interact in real time.Finally,take the tour guide practical course as an example to establish a teaching database,design scenes,perform virtual role-playing and emergency simulation exercises,teaching recording and playback,and apply tests on the platform to demonstrate the application effect of the platform in the tour guide practical course.The effectiveness and feasibility of the system were verified.
