Research Of Virtual Hand Human-Computer Interaction Based On Data Glove

In the field of virtual reality,because of the key position in the interaction process of the hands,the research on virtual hand human-computerInteraction has always been a hot topic.Compared with the traditional way of human-computer interaction,the way of interaction based on virtual hand is more natural and efficient,this paper mainly studies the implementation of human-computer interaction based on the hardware of data glove.This paper analyzed the component in a virtual hand human-computer interaction framework from the theory of virtual hand human-computer interaction firstly,and then their function to realize in detail respectively,at last,it put forward the main technical problems need to be solved to complete the system on the basis above.Then the article studies the process how to map a hand to a virtual hand.Firstly,from the bone structure and motion characteristics of man hand,it uses the idea of object-oriented in programming language to finish the modeling of virtual hand;secondly it introduced the composition principle and using method of the key virtual reality hardware-data glove used in the paper;Finally,it studies the mapping of a real hand to a virtual hand from the coordinate system,put forward the related solutions at the same time.Then the key technologies related involves in the completion of the process of human-computer interaction is discussed in detail.At first,the construction of the virtual environment is completed under the condition of using OpenGL kit from theory of scene tree;then it studies the problem of collision detection which must be solved in virtual reality interaction,here it mainly introduces four common measurement methods under the algorithm of bounding box;at last the rules that virtual hand must follow is made under the action of scraping.At the end of this article, under the software configuration of visual studio 2010 ?OpenGL development environment and Windows 7 operating system,by the using of 5DT Data Glove Ultra,a human-computer interaction instance based on virtual hand is completed.
