Introduction To Virtual Reality Technology

The introduction of Virtual Reality Technology

Virtual reality technology is a kind of simulation system that can create and experience virtual world. It uses computer to generate a simulation environment. Interactive 3D dynamic visual and physical behaviour simulation makes users immersed in the Environment.

Virtual Reality Technology (VR) mainly includes simulation environment, perception, natural skills and sensing equipment, etc. Perception means that the ideal VR should have all of the perception that people have. Except visual perception generated by computers’ graphic technology, there are hearing, touching, force perception, movement and other perception, even including the sense of smell and taste, also known as multi-perception.

These techniques are separately described below.

In contrast, using computer models to generate graphics and images is not too difficult. If there is enough accurate model and time, we can generate a variety of images of objects under different lighting conditions, but the key here is real-time. For example, in a flight simulation system, image refreshing is very important, meanwhile the image quality requirements are also high, coupled with a very complex virtual environment, the problem becomes more difficult.

In the VR system, binocular stereo vision plays a significant role. User’s eyes see different images are generated respectively displayed on different monitors. Some systems use a single display, but the user with special glasses, one eye can only see the odd frame images, the other eye can only see even frame images, the difference between the frames, which called ‘parallax’, produces a three-dimensional

Virtual campus is the earliest specific application of virtual reality technology in education and training. It has three application levels from shallow to deep, which are adapted to the different needs of the school: the simple virtual campus environment for visitors to browse teaching. Three-dimensional visualization campus relatively have more completely functions, it adds a series of user-friendly features to virtual reality. Virtual remote education can provide mobile teaching sites for campus. Provide interactive teaching classes and websites for distance learning, through links to campus websites by LAN tools for each user. It also accelerate the developments of new technology, and higher vocational training opportunities, create greater economic and social benefits. With the continuous development and improvement of virtual reality technology and the decreasing price of hardware equipment, we believe that virtual reality technology will be valued and favoured by educators with its strong teaching advantages and potentials. Training areas widely used and play an important
