Design And Development Of Physical Optics Virtual Laboratory Based On Multi-modal Interaction

The rapid development of information technology has provided new ideas for subject teaching.How to effectively apply information technology to subject teaching is a hot spot of current research.In subject teaching,physics experiment teaching is often the focus of educators’ attention,because in actual teaching,most schools have limited experimental conditions that cannot meet the learning needs of each student,resulting in poor experimental teaching effects.The emergence of the virtual laboratory has created good experimental learning conditions for students.Students can carry out experimental learning without being restricted by time and space,and cultivate their experimental operation ability to the greatest extent.At the same time,students can also observe in the virtual laboratory Experimental phenomena that are difficult to observe in real experiments help students better understand experimental principles.In view of this,this research uses multimodal interaction as the carrier,somatosensory interaction technology as the key technical support,and takes the physical optics experiment content in the high school physics curriculum as the starting point,and uses the Leap Motion somatosensory device to design and develop a new model based on multimodality.Physics and optics virtual laboratory for dynamic interaction.The first chapter analyzes the relevant national policy documents on promoting the application of new technologies,the research background of educational modernization,and the current status of classroom teaching in middle schools.The focus of the research is on the physical experiment classroom,and the integration of virtual reality technology and multi-modality are proposed.The purpose and significance of interactive and somatosensory interaction technology to develop the physical virtual laboratory are described in detail on the main content of the research and the specific methods adopted by the research.Chapter Two uses the literature research method to sort out and analyze the literature of multimodal interaction,somatosensory interaction technology and virtual laboratory at home and abroad in recent years.Summarized the current research situation is that virtual laboratories are mainly based on graphic design,and the three-dimensional sense is not strong,and some virtual laboratories developed based on Unity 3D do not incorporate multi-sensory interaction methods and are not immersive,so the author once again proposed Combining the current research hotspots with multi-modal interaction methods,develop a virtual laboratory that integrates multi-sensory interaction methods,and analyze the factors that need to be considered in design and development through related theoretical foundations.Chapter 3,by issuing questionnaires and interviews,investigates the needs of the application objects,clarifies the specific physical experiment content and corresponding functions developed by the virtual laboratory,puts forward the design goals and principles,and comprehensively considers other factors.Carry out the functional module division and frame logic design of the physical optics virtual laboratory based on multi-modal interaction.The fourth chapter discusses in detail the specific development process of the physical optics virtual laboratory based on multi-modal interaction,including the selected development tools,the key technologies used in the development and the realization of key functions.The fifth chapter discusses the application process of the physical optical virtual laboratory in the physics experiment classroom and the analysis process of collecting application data.According to the data results,the conclusion of the application effect of the physical virtual laboratory in teaching is summarized.Chapter VI summarizes the whole research content,puts forward the innovations and shortcomings of this research,and puts forward the corresponding prospects for the follow-up research.The physical-optical virtual laboratory based on multi-modal interaction integrates a variety of sensory interaction methods,allowing users to feel the charm of the virtual laboratory from various aspects of vision,hearing,and touch.It changes the interactive methods of traditional virtual laboratories and improves The fun of the learner’s learning process enhances the learner’s sense of immersion.At the same time,the integration of current research hotspots and multi-modal interaction methods have designed and developed specific teaching content,which also provides new ideas for the research field of the integration and application of education and emerging technologies.
