Research On Evaluation Method Of Gesture Interaction Design In Immersive Environment

Interactive evaluation is one of the important research issues of human-computer interaction.In human-centered interactive system of immersive environment,accurate evaluation of human body state can provide a strong basis and guarantee for interactive design in immersive environment.With the development of Virtual Reality(VR for short),the way of using gestures to interact with the immersive environment is on the rise.However,the traditional evaluation method is difficult to effectively evaluate the user's interaction state in the immersive environment,making it difficult for the corresponding gesture interaction design to meet the interaction requirements.In this paper,aiming at the evaluation design method of gesture interaction in immersive environment,two quantitative evaluation indexes based on gesture data of interaction trajectory and task completion data are studied.Because immersion environment gesture interaction system of the assessment system is not perfect,as the design immersion environment difficult gesture interaction assessment model,this article first embarks from the rule of the establishment of the evaluation model,set up the evaluation model based on objective data,then create the immersion experiment environment to collect experimental data,and again through the analysis of experimental data,how to optimize the environment of immersion of gesture interaction,finally transform analysis result into the actual system application,the specific work includes:(1)starting from the system analysis and combining the existing evaluation methods,the evaluation criteria of the prototype system of gesture interaction in immersive environment were established.Firstly,starting with the process of human-computer interaction prototype system analysis,the prototype system of gesture interaction design in immersive environment is analyzed.Secondly,by studying the evaluation methods commonly used in the field of human-computer interaction,the evaluation methods suitable for the gesture interaction design in the immersive environment are obtained.Finally,combining with the establishment criteria of the human-computer interaction evaluation model,the evaluation criteria for the prototype system of gesture interaction in immersive environment are established,which consists of five points:evaluation objective,evaluation mechanism,evaluation mechanism,evaluation index,evaluation method and effective scope.(2)based on the evaluation criteria,the GT evaluation model based on objective data wasestablished,and its effectiveness was verified through the design of immersive experimental environment and interactive tasks,and the optimization method of gesture interaction in the virtual reality environment was proposed.First,according to the established evaluation criteria of the prototype gesture interaction system for immersive environment,and combining the performance measurement method and the action trajectory method in the current evaluation methods of human-computer interaction field,a GT(Gesture & Task)evaluation mod was established to collect objective data in a task-driven manner.Secondly,an immersive experimental environment was established by combining the Unity3 D platform,and interactive tasks in accordance with natural gesture interaction were designed through the scene to collect the objective interactive data and subjective psychological data of the experimenters.Thirdly,through certain visualization and analysis methods,GT data were compared and verified.Finally,through the analysis of experimental data,an optimization method of gesture interaction in virtual reality environment is proposed.The experimental results show that the optimization method can effectively improve the interaction accuracy.(3)starting from the optimization method of gesture interaction in the virtual reality environment,the virtual chemistry experiment system was designed.Chemical experiment,the author of this paper in the simulation of interactive purpose is not clear,the problem such as training data are difficult to intuitive performance,and the proposed virtual reality based on Unity3 D platform environment optimization method of gesture interaction,designed and developed a visualized by virtual chemistry experiment operation side,site,account with the experimental data is stored virtual chemistry experiment system.
