The Interaction Design Research Of Three-Dimensional Virtual Simulation Experiment System

Nowadays,computer technology,network technology and virtual reality technology are more and more applied in the field of education,which makes teaching and learning become more diversified and more innovative.Correspondingly,many educational application patterns related to the above technologies have emerged in large numbers,and the three-dimensional virtual simulation experiment is one aspect of the research and attention of many scholars and teachers.Nowadays,three-dimensional virtual simulation experiments are faced with the problems of simple interaction,poor participation and poor attraction,which make the effect of experiment teaching weakened.In order to improve the above problems,the author studies the interaction design of the theory and method.Firstly,this thesis,with the analysis of three-dimensional virtual simulation experiment system interaction design research status and the related theoretical basis,applies the emotional design theory to the interaction design of three-dimensional virtual simulation experiment system and elaborates the guidance levels,including the sensory level,operation level and emotional level,of the emotional design theory for the three-dimensional virtual simulation experiment system interaction design.Secondly,through the analysis of the above three levels,the interaction design model,which consist of two levels of emotional sensory design and emotional operation interaction design,is proposed.In the interaction design model,the above two levels of design are all based on operation object.Emotional sensory design includes inherent sensory design and feedback sensory design,and emotional interaction design includes task analysis,operation analysis and feedback analysis.At the level of emotional sensory design,the design principles of the three-dimensional virtual simulation experiment system are proposed.At the level of emotional operation interaction design,the method of hierarchical task analysis(HTA)is used to decompose tasks;the mode of operation are summarized through user operation actions decomposition based on mouse and keyboard device;the feedback patterns and design principles are summarized.After that,the user task,the operation mode,the operation object and the feedback mode are mapped analysis,and the mapping principles are summarized.And then,based on the above analysis and the actual design,this paper puts forward the interaction design process of three-dimensional virtual simulation experiment system.Finally,the author chooses "kalavinka schoolhouse digital exhibition",a liberal arts three-dimensional virtual experience,and"micro nano metal wire drawing",a science three-dimensional virtual experiment,as representative cases to interaction design.And then through the user experience questionnaire survey,the rationality of the design process and the validity of design methods and principles are verified.The thesis hopes that the study can provide users with more smooth operation,more pleasant experience and a certain reference value for the relevant virtual experiment design and development in the future.
