Research And Implementation Of Gesture Interaction In Virtual Reality Interactive Games

With the continuous development of virtual reality technology,people are increasingly eager for natural interactions.Especially for heavy interactive games,the satisfaction of interaction directly affects the value of the game.There are natural advantages in using natural interaction gestures in virtual reality games,but currently there is a lack of reasonable and effective gesture design methods.This article studies the interaction of gestures in Leap Motion-based virtual reality games,using techniques such as computer vision and image processing.Gesture interaction enables the acquisition of natural gestures,the extraction of gesture features,the recognition of gestures,and the response of user needs.This paper first studies the related theory of gesture interaction and then extracts the basic interaction requirements in the virtual reality game,uses the prototype theory to extract the basic gesture gestures,and proposes the basic design method of the gesture.Improve the existing interaction model and apply it to interactive design of games,the main tasks include:(1)Analysing the problems brought about by the interactive methods used in virtual reality games at present,investigates the research status and application of virtual reality games related technologies at home and abroad,and clarifies the research significance and research contents of this paper.(2)The basic classification of hand gestures and its connection with semiotics are studied.The existing GOMS model is extended and applied in the virtual reality environment.The basic flow of the entire gesture interaction is elaborated,and the basic factors affecting the interaction efficiency of gestures are presented.Basic principles of design(3)Using prototype theory combined with basic interaction requirements and the semiotic relationship of gestures,the basic gesture gestures of gesture interaction in virtual reality are drawn,the basic characteristics of gestures are analyzed,and the basic characteristics of gesture interaction in virtual reality games are used.Mathematical expressions are used to extract some gesture features.Ways to describe gestures and use gestures to express ideas in a modular way.(4)Using game engine Unity3 D and Leap Motion to develop a virtual reality gesture interactive game,applying the above-mentioned gesture design method to the game and analyzing the factors that affect the efficiency of gesture interaction,and using the easy-to-use test for designing gesture interaction to verify the gesture design method Usability.The design practice proves that the gesture design method proposed in this paper can effectively guide the interaction design of the entire game,using the GOMSVP model proposed in this paper to describe the gesture interaction process in the game,and reduce the factors that affect the interaction efficiency.Reference and guidance for the application of gesture interaction in virtual reality...
