The Design Of 3D Space Interface Based On Natural Gestures Interaction

With the development of virtual reality and augmented reality technologies,a three-dimensional space interface different from that displayed on a two-dimensional screen is spawned,and it also provides a platform for natural interaction methods such as language and gestures.In human-machine dialogue based on the three-dimensional space interface of the head-mounted display,gesture interaction becomes the main interaction method.This subject focuses on the mutual restriction mechanism and design method between the interaction method of natural gestures and the display method of the three-dimensional space interface.(1)The article summarizes and analyzes existing research and interaction examples,collects the types of gestures and poses commonly used by current users,and obtains the coding method of gesture interaction by deconstructing and assigning interactive gestures;(2)Conduct behavioral experiments in VR,and observe the performance of the subjects.The results of the experiments use the analysis method of mean variance and correlation to obtain the effect of depth space and control size on user gestures;(3)Through the interactive semantics of the natural gesture posture at the current stage,combined with the interactive tasks and information relationships applicable to the gesture interaction in the three-dimensional space,the interface layout method based on the natural gesture in the three-dimensional space is obtained;(4)Finally,the theoretical results are comprehensively applied to the example design,and the unity platform is used to complete the system design and development of interactive scenes under virtual reality.The research obtained the mapping mechanism between interface information relations and gestures,the influence of display depth and size on gestures,and the interface design criteria in three-dimensional space.The research results provide method guidance for the interaction design in three-dimensional space and enhance the user's operating experience in the future three-dimensional space system.
