Virtual Reality (VR) was created to fulfill human curiosity about exploring beyond the reality. Humans establish the experiences of a real world based on the feedbacks from sense organs, such as eyes, ears, nose and hands. By replacing real images, sound and tactility with computer-generated illusions, a virtual world can be built for the human user to navigate in and interact with. In this book, the authors gather current research from across the globe in the study of virtual reality including education processes implemented in the simulated environment of the laboratory; an intuitive 3D interface infrastructure for virtual reality applications; virtual environments for the visualization of cultural and archaeological heritage; virtual reality in psychotherapy and autism; and, virtual reality as a tool for machining-processes simulation and in the textile field.
