Virtual reality design is a comprehensive integrated
technology involving computer graphics,
human-computer interaction techniques, sensor
technology and artificial intelligence, it produces vivid
three-dimensional computer-generated visual sense,
sense of hearing and sense of smell, making participants
through appropriate device experience and interact with
the virtual world naturally. When the participants have
location shift, the computer can immediately conduct
complex calculations, and return accurate 3D images so
that a sense of presence can be generated
