Research On The Design Of Gesture Semantic Symbols In 3D Interface In Augmented Reality

With the development of augmented reality technology,natural and intuitive humancomputer interaction is the focus of current augmented reality technology research.In the threedimensional space based on augmented reality,good visual instructions or feedback information can effectively reduce the user's misunderstanding of interaction intentions and gesture input errors.Reasonable,efficient and satisfactory natural gesture operation is an important research content of natural human-computer interaction in augmented reality.Firstly,use user heuristics to study the semantic symbols of gestures,use user-centered concepts to design common gestures for interactive operations such as movement,rotation,and zoom in augmented reality,use expert scale evaluation methods to determine the set of gestures,and apply them to three-dimensional interface feedback in experiment.Secondly,by studying the visual characteristics of indicating semantic symbols in augmented reality interfaces,three-dimensional interface symbols are classified,and visual symbols with clear semantics are designed.Evaluate the impact of semantic symbols in the 3D interface on the time and error rate of gesture operations.Through research,it is found that the self-adaptive visualization element and the gesture semantic matching effect are good,improve the efficiency of gesture operation,and can be applied to the design of augmented reality 3D interface.Finally,the mobile augmented reality teaching app is used as a research and design practice,through user research methods to conduct task analysis and demand collection of users,complete the design of interface elements and natural gestures,integrate the design of natural gestures,human-computer interaction,and enrich user interactions Ways to improve the user' s interactive experience.Through the evaluation and test,the effect is good.This article helps to make augmented reality improve the visual interface of gesture interaction and reduce the cognitive burden,save the time for users to learn and understand,and achieve more efficient operation goals.In the design practice in the direction of teaching guidance,the feasibility of the gesture design method is verified.In addition,the idea of symbolic semantics can provide ideas for the design of three-dimensional interface and gesture semantic symbols in the future.
