Research On Realization Method Of Infinite Walking Space In Virtual Reality Environment

With the rise of meta-universe,the development of 5G technology and cloud technology,virtual reality technology has gradually entered the life of the public.Virtual reality technology has three characteristics: immersion,interactivity and imagination,which can improve people's life quality in the new era.However,virtual reality technology still uses the interactive scheme of handle movement,which leads to motion sickness and the lack of immersion.In virtual reality mobile interaction,there is still a lack of a real walking and moving scheme that is more in line with natural interaction behavior.After background research and current situation analysis,there have been some researches on virtual reality walking interaction schemes,such as Vientiane treadmill scheme and redirection scheme.However,these solutions are expensive to implement and narrow in scope of application,so they are difficult to become the main mobile interactive solutions in virtual reality technology.To solve the above problems,this thesis studies the realization method of virtual reality infinite walking space.Firstly,this thesis studies the real walking interaction,redirection walking scheme and non-Euclidean space walking scheme in virtual reality environment,and studies the self-overlapping scheme in detail.Secondly,this thesis summarizes the differences between real walking interaction and traditional virtual reality mobile interaction,analyzes the design requirements of virtual reality infinite walking space,studies the design principles of infinite walking space scenes,and completes the frame design of completely self-overlapping space and partially self-overlapping space.Then,this thesis studies the space connection rendering technology and space area enlargement technology of self-overlapping space,and realizes the virtual reality infinite walking space prototype based on these two technologies.Finally,based on the prototype of virtual reality infinite walking space,this thesis develops two sets of virtual reality real walking systems,complete self-overlapping space and partial self-overlapping space,respectively.The two systems are tested respectively,and the conclusion is drawn that part of self-overlapping space can better realize the interactive experience of virtual reality infinite walking space.
