全球化已将工程设计转变为由分布在各地的专家团队在全球范围内开展的工作。 VR 在设计中的广泛采用以及在设计审查任务中直接在讨论对象上进行操作和放置标记的需要导致了对虚拟协作环境中注释的研究。然而，传统方法尚未超越黄色便利贴+文本隐喻。事实上，音频、草图、视频和动画等多媒体提供了更大的表现力，可以在协作环境中得到很好的利用。此外，单独的注释无法捕捉讨论的基本原理和流程，而这对于理解项目设计决策至关重要。一个典型的例子是海上工程项目，这些项目通常需要分布在不同地区的高度专业化的工程团队，并且由于项目成本以及在审查深水石油和天然气平台设计时需要降低风险，因此需要提高生产率。在本文中，我们提出了一种丰富的、结构化的多媒体注释的方法，以支持设计审查任务中的讨论和决策。此外，我们的方法支持基于问题的论证，以揭示设计决策的出处，从而更好地支持工程项目的工作流程。虽然这是对解决方案空间的初步探索，但示例表明协作设计审查比传统方法有更大的支持。
Globalization has transformed engineering design into a world-wide endeavor pursued by geographically distributed specialist teams. Widespread adoption of VR for design and the need to act and place marks directly on the objects of discussion in design reviewing tasks led to research on annotations in virtual collaborative environments. However, conventional approaches have yet to progress beyond the yellow postit + text metaphor. Indeed, multimedia such as audio, sketches, video and animations afford greater expressiveness which could be put to good use in collaborative environments. Furthermore, individual annotations fail to capture both the rationale and flow of discussion which are key to understanding project design decisions. One exemplar instance is offshore engineering projects that normally engage geographically distributed highly-specialized engineering teams and require both improved productivity, due to project costs and the need to reducing risks when reviewing designs of deep-water oil & gas platforms. In this paper, we present an approach to rich, structured multimedia annotations to support the discussion and decision making in design reviewing tasks. Furthermore, our approach supports issue-based argumentation to reveal provenance of design decisions to better support the workflow in engineering projects. While this is an initial exploration of the solution space, examples show greater support of collaborative design review over traditional approaches.
