Research On User Behavior Consistency Of Interactive Virtual Reality System Based On Motion Capture

With the continuous development of virtual reality technology,people are no longer satisfied with simple visual experience,but gradually rise with interactive virtual reality system.At present,most of the existing virtual reality systems with interactive functions are users interacting with virtual objects,or multiple users interacting in the same scene,but no human body can be seen.The two interactive ways can significantly reduce the user immersive,according to the disadvantages of the existing virtual reality system has developed a set of interactive virtual reality system based on motion capture,the users of the system not only can interact and virtual objects,also can interact with virtual people,greatly increase the interest of the user experience.At the same time,using the virtual reality system,the consistency of user interaction behavior in the virtual environment is studied.The main research contents are as follows:(1)Research on the motion control of virtual human.In this part,the skeleton structure of the virtual human is studied first.Through the analysis of its skeleton hierarchy,the essentials of the virtual human motion editing are mastered.Then the Qualisys motion capture system used in this paper is introduced deeply,and the data form and process obtained by it are analyzed.Finally,the principle of virtual human motion control is analyzed for motion capture method.(2)Research on consistency of throwing behavior of users based on multi-factor analysis of variance.This study describes a whole set of processes from the overall design of the virtual reality system to its implementation.Unlike other VR systems,this VR system combines optical motion capture technology,and virtual human objects are added into the VR system.Finally,the collected data are analyzed by the method of multi-factor ANOVA,and the consistency of throwing behavior of users in virtual environment is studied.Some important results are obtained,for example,the "speed" of walking in VR has almost no effect on throwing accuracy.This study provides an important reference for future research on user action consistency in virtual environment.(3)Research on consistency of user interactive throwing behavior based on generalized linear mixed model method.As the system developed in the last part adds virtual human objects,the motion catcher who controls the virtual human cannot see the scene in the VR system.Therefore,based on the previous system,the system further developed a set of multi-person interaction system based on motion capture.The system not only inherits the functions of the previous system,such as real-time driving of virtual human and throwing ball in virtual environment,but also uses the UDP network transmission protocol to solve the problem of data transmission between scenes,and realizes the function of interaction between motion capture and user in VR environment.Finally,the VR system was used to collect data according to the designed experiment,and the data were analyzed by the method of generalized linear mixed model in SPSS.The study yielded a number of important observations that will inform the future development of virtual reality systems,as well as future developments related to motion throwing.
