THE RESEARCH AND DEVELOPMENT OF
INFORMATION INTERACTION TECHNOLOGY OF
VIRTUAL REALITY

ABSTRACT

With the development of displaying, high-speed graphic, sensoring,
multimedia and video technology, Virtual Reality Technology is
receiving interest from more and more researchers, and Its applications
have gone into nearly every fields: Military, Aero, Medical,
Arctecture,and Mechinery,etc,. Relatively speaking, China has just begun
the research on this advanced technology during recently years, as for its
application to medical, and especially for its application to Virtual
Operation, this kind of more difficult technology, related research is less.
In this thesis, in order to develop a virtual operation system, some key
technologies of virtual reality, such as sound simulation, guiding
technology, animation, scientific data visualization, Human-Machine
Interaction and 3D modeling have been researched. Most virtual reality
systems only offer visual reflection and it is a mute virtual world. This
thesis creates a virtual world with sound and realizes 2D and 3D sound
simulation on basis of DirectSound and WTK technologies. To help users
better understand some specialized virtual reality system, the
