虚拟现实及增强现实技术在工业设计中的应用

Virtual and augmented reality applications in industrial design

工业设计技术已日益成为产品创新、价值增值过程中重要的手段。由于现有技术支撑手段的局限,传统工业设计过程中反复叠代修改的"设计-快速原形(CAD>RP)"循环制约了设计师发挥的空间。虚拟现实及增强现实技术的应用可以为设计师提供一个自然、辜观、交互的环境表达设计思想。虽然已有大量的文献描述混合现实技术的进展及其在制造业的应用,但还鲜有专门着重于工业设计这一重要的领域。本文从一个工业设计工程师的角度阐述了混合现实技术在工业设计中的应用,尤其着重于在增强现实环境下的三维空间设计、数字样机和虚拟装配,并与现有的设计方式进行了比较。

Industrial design has become crucial to the products innovation and value-added process in current highly competitive marketplace,In order to provide designers nature and intuitive means to express their ideas freely and overcome the technical gap in the iterative design process,virtual and augmented reality technologies are employed to supplement the traditional Computer Aided Design-Rapid Prototyping（CAD-RP） iterative design process.Although there exist a vast amount of literature on facilitating mechanical design and manufacturing with virtual and augmented reality technology,not much has been summarized specially on the mixed reality aided industrial design space.This paper has surveyed the development of virtual and augmented reality applications in industrial design from a designer＇s perspective,with a particular focus on spatial design,hybrid prototyping and assembly in an augmented environment.It provides a comparison between traditional design process and the improvements affected by mixed reality technology that both designers and researchers could benefit from it.
