虚拟现实及触觉交互技术:趋势与瓶颈

Virtual Reality and Tactile Interaction Technology:Trend and Bottleneck

虚拟现实是当前的前沿和热点。本文阐述了虚拟现实的概念、发展历程、虚拟现实系统及部分关键技术,并对虚拟现实、增强现实、介导现实和混合现实等概念的内涵进行了溯源和诠释。虚拟现实在内涵上既有交集又各有特异性,难以简单地用包含或被包含关系去进行描述。触觉技术对于虚拟现实系统的交互性具有重要价值,在阐述虚拟现实系统的基础上,论文进一步介绍了触觉交互涉及的触觉传感和触觉显示技术及相关产品。论文最后讨论了制约虚拟现实发展的一些关键技术瓶颈。

Virtual reality is a leading technology and hot topic currently This paper, firstly, expounds the concept, development history, system diagram and key technologies involved in virtual reality. Then this article investigates the origin of the connotation of some terms including virtual reality, augmented reality, mediated reality and mixed reality and explains them as well. This paper suggests that the above concepts appear to be mixed with each other, but have their own uniqueness and are not overlapping in relationship. The haptic/tactile technology plays an important role in virtual reality for a natural and perceptual experience, and the tactile sensing technology, tactile display technology and related products for haptic interaction are further introduced. Finally, some key technology bottlenecks which restrict the development of virtual reality are discussed.
