Virtual reality (VR) is a computer technology that uses virtual reality headsets or multi-projected environments, sometimes in combination with physical environments or props, to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual or imaginary environment.

In the present book, fifteen typical literatures about Virtual Reality Applied Technology published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on Medical application, civil application, ect. We hope this book can demonstrate advances in Virtual Reality Applied Technology as well as give references to the researchers, students and other related people.
