With the development of virtual simulation technology and the maturity of related software and hardware,the learning resources created by virtual simulation technology are realistic in environment,physics and behavior,which can break through the limitation of time and space,and not be restricted by the objective conditions such as site and equipment to be operated indefinitely until the ideal effect is achieved.It can effectively solve the many difficulties in the current teaching operations,such as experiment,practice and internship,etc.However,there are many problems in the application of virtual simulation resources,such as the sick feelings of long time learning,the lack of high dimensional interaction and information feedback,the lack of learner's initiative to explore independently,etc.Therefore,it is urgent to explore a solution that can not only construct a simulation environment with high immersive comfort,but also consider learners' behavior and feelings.In this paper,from the aspects of immersion comfort,diversity and authenticity of haptic interaction feedback and analysis of interactive behavior,It integrates haptic feedback interaction into virtual simulation resources to design a immersive virtual simulation resource based on haptic feedback to assist students.Improve the ability of independent exploration and efficient learning in virtual simulation environment.The main research content of this article is as follows:(1)Analyze the deficiencies in immersion,interactivity and other aspects of virtual simulation resources,combine stereoscopic display and tactile feedback,to determine the guidance theory and design flow of immersive virtual simulation resources based on haptic feedback.(2)Explain the key technologies of immersive virtual simulation resources,define parallax types according to depth information of perceived objects,complete scene layout based on the optimal stereo comfort zone range,and design a tactile interaction and feedback model based on vibratory tactile reproduction technology In order to improve the efficiency of scene rendering and collision detection,the methods of scene optimization in the interaction process are explored.(3)According to the classification of haptic interaction in simulation resources,the whole interaction process is divided by key events points and then the types of tactile interaction and the change of system state in the interaction process are described.Through collecting the interactive data of key interactive event points,collating and summarizing the evaluation factors of interactive behavior analysis,constructing evaluation model and analyzing the learning behavior,process and effect of learners,and providing more comprehensive results feedback for the learners,instructors and developers.(4)Taking the experiment of seed germination in the biology experiment of high school as an example,the virtual simulation resources are constructed.According to the requirements of the experiment,the scene construction,the haptic interaction design and development are completed,and the questionnaire survey method is used to evaluate the experimental system.The results show that it is effective and feasible to apply the haptic interactive design method to the virtual simulation resource.Feasible,it can help students to explore independently and learn efficiently in virtual simulation environment.
