Research On Human-Computer Interaction Technology Based On Data Glove And Tracking Device

The virtual reality technology in the short several years already in the industry, the medicine, the education, the entertainment and the military and so on many domains obtained the application and the development, caused the common people widely to pay attention, and was playing the significant promotion effect to the related domain."Interaction"is one of virtual reality technology essential features, and is also the virtual reality technological development driving force. Under the virtual reality technology's influence, the human-computer interaction technology has been developed from"the human adapts the computer"of the traditional information processing environment to realize"the computer to adapt the human"gradually. In the way the traditional monitor, the keyboard, the mouse and so on transforms which face computer's hardware equipment transformed into the helmet type monitor, the data glove, the space-tracking equipment and so on which face person's characteristic equipment. In the content no longer limits to the numerical calculus, the language processing interaction, but is expands to the image, the sound, the language and so on many kinds of form interactions. In the effect it achieves the lifelike virtual environment to cause the feeling which the user produces experiences personally.The hand signal is in the human daily life between the human and human the most natural one interactive mode. The computer provides humanity's nature interactive skill for the people, and carries on with its creation's virtual environment directly alternately, achieves or the close human daily nature interactive keenness and accurate, and it is one of virtual reality engineering research primary coverages. This paper take the data glove and the tracking device as the interactive equipment, realizes the hypothesized hand based on the hand signal recognition technology and the display control as well as carries on operations and so on selection, migration, release in the three dimensional scene to the hypothesized object model, mainly includes the following several aspects:Firstly, analysis from the physiology overall manpower's skeleton characteristic and the joint degree-of-freedom, has discussed the three dimensional modeling technology, OpenGL drawing technology and the skeleton outer covering animation technology ,has established the hypothesized hand static model;Secondly, analysis manpower movement characteristic, describe the hand skeleton's level relations and the movement space in detail, has established the hypothesized hand skeleton and analysis situs relations. It has analyzed the hypothesized hand's motion control principle thoroughly, introduced specifically the model geometric transform principle, has constructed the hypothesized hand's movement model, and realized the hypothesized hand's dynamic control. It has studied the skeleton outer covering animation technology, and solved the joint boundary skin tearing distortion problem;Thirdly, introduce in detail data glove's principle of work.It has established the data glove and the hypothesized hand's movement mapping process. It has analyzed the hand signal recognition technology principle, and studied based on data glove's hand signal recognition process;Fourthly, discusse the virtual reality technology concept, the duty and the operation classification. It has analyzed tracking device's principle of work, unifies the data glove, the application ray cast technology, and realized based on the hand signal recognition hypothesized choice and the operation process;Fifthly, in VC++, has constructed using the OpenGL three dimensional graph procedure based on the data glove and tracking device's human-computer interaction system. This system use data glove and the tracking device these two kind of model interactive equipment, to realize in the virtual environment the hypothesized hand demonstration and the dynamic control human-computer interaction function.
