Virtual reality and augmented reality in industry

摘要

Virtual reality/augmented reality(VR/AR)has been widely used in the industrial fields,such as product design,manufacturing,assembly,maintenance,performance evaluation and other life cycle stages.The technical characteristics of VR can be summarized as virtual world,immersion,sensory feedback,and interactivity.The virtual world or virtual environment(VE)is a mapping of the real world.By reproducing the real environment,the operator can interact with the virtual world truly.For the research and application in the industrial fields,the modeling and simulation of the virtual world reflecting the physical nature are particularly important.
