在异步在线讨论中，用户主动引用视觉材料（例如视频、文档）以提供支持证据和附加背景。然而，创建和理解复杂的参考文献可能具有挑战性，特别是当有多个参考对象需要参考时，或者当参考对象非常具体时（例如，论文中的特定句子而不是整个论文）。为了确定用户在使用现有讨论工具时使用多个和特定参考对象进行参考时遇到的挑战，我们进行了观察性研究和初步访谈。根据设计经验，我们构建了 Korero，一个旨在促进复杂参考操作的讨论界面。为了进行评估，我们在两项用户研究中将 Korero 与传统界面进行了比较，其中涉及不同参考难度的参考任务。我们发现，Korero 不仅显着减少了使用多个和特定参考对象进行参考的时间和精力，而且还显示出提高用户对讨论和参考材料的参与度的潜力。
In asynchronous online discussions, users actively reference visual materials (e.g., video, document) to provide supporting evidence and additional context. However, creating and comprehending complex references can be challenging, especially when there are multiple referents to refer, or when a referent is highly specific (e.g., specific sentences in a paper rather than the paper as a whole). To identify users' challenges in making references with multiple and specific referents while using existing discussion tools, we conducted an observational study and a preliminary interview. Based on the design lessons, we built Korero, a discussion interface that aims to facilitate complex referencing actions. For evaluation, we compared Korero against conventional interfaces in two user studies with referencing tasks of different referential difficulty. We found that Korero not only significantly reduces the time and effort in making references with multiple and specific referents, but also shows potential in increasing users' engagement with the discussion and referent materials.
