| The emerging and development of virtual reality has put forward new challenges and requirements for the design of user interface.Compared with traditional user interfaces,the spatial properties of virtual reality are a great challenge to the original design methods;compared with real space,the information space of virtual reality is an expansion and an opportunity for it.The spatial experience that humans get in real physical space allows us to quickly understand and control the environment and information,and how users perceive the virtual reality space will greatly affect the way they interact with it.This study proposes a framework for virtual reality user experience,which focuses on the first three steps of "perception"-"intention"-"behavior"respectively.This study proposes a framework for virtual reality user experience,and conducts experimental investigations on the first three steps of "perception"-"intention"-"behavior" to fully explore users’ perceptions and cognition of virtual reality space,and use them to guide the design of examples.Firstly,from the spatial information value in image grammar,the experiment was conducted to explore the relationship of users’ spatial information value in virtual reality,and the conclusion was used to guide the layout of virtual reality information space,so that the information attributes can better conform to users’ cognition and thus improve the fluency of interaction.Secondly,the user’s interaction preferences in the 3D information space of virtual reality are explored with respect to the user’s perceptual matching of different spaces and different interaction channels.The experimental findings can provide reference for the selection of interaction methods in the 3D space,and provide more matching interaction methods for interaction tasks in different spatial areas,so as to reduce the user’s cognitive burden and fatigue,and enhance the naturalness,intuitiveness and immersiveness of the experience.Finally,this study selects 34 generic interaction tasks in virtual reality in 4 major categories,explores the consensus set of action features that match user intuitiveness,and organizes the dominant action features generated by users,which can provide a basis from user intuition when designing interaction behaviors,thus helping developers and designers to design systems that better match users’ cognition.At the same time,the optimal 34 specific interaction actions were selected as the standard input actions in this study,forming a consensus set of hand-eye actions.This was applied to the design examples in Chapter 5.In the process,the spatial perceptions in the user production actions were also collected and summarized as a supplement to the user’s conclusion on the information value of the virtual reality information space.Through the above research and analysis,this study designed the example "VR Modeling" with virtual reality modeling scenes,completed the scene design,scene construction,interaction development and user testing,and finally the feedback from the tested users is good,which also confirms the value of the previous theories to some extent. |
