HCC: Supporting Disciplined Improvisation During Face-to-Face Discussion

即兴创作是富有成效的面对面讨论的标志，有助于产生创新的新闻想法或见解。尽管即兴发挥很重要，但支持讨论的计算工具侧重于支持固定的活动指令，如多项选择评估、想法收集、排名或概念图。为了支持即兴表演中涉及的动作，我们对有趣的、面向参与的技术的必要性进行了理论推导。这样的技术必须高度灵活，并支持一系列的表示，例如，不仅是文本，而且还有草图和特定于领域的符号。即兴创作的元过程施加了一个正交要求：需要从新的角度思考人工制品，然后将它们转换为新的表示形式。这个项目调查了技术在一种称为“有纪律的即兴发挥”的特定形式的敏捷性能中所扮演的角色。在这项工作中，我们将(1)开发一个支持有纪律的即兴表演的理论框架，(2)将一个称为“Group Scriblble”的原型课堂工具适应于有纪律的即兴表演的背景，以及(3)研究反复评估系统对有纪律的即兴表演的支持程度的方法。最后，这个项目旨在为我们提供新的线索，说明在我们学习和解决与周围人的问题时，技术如何能够实时地帮助我们。我们预计，我们的发现将为课堂教师和讨论主持人带来更好的软件和硬件。这项工作建立在对计算机支持的协作工作的先前研究的基础上，但通过研究基于计算机的工具如何支持曲折的现场表演而开辟了新的天地。

Improvisation is a hallmark of highly productive face-to-face discussion that leads to innovative news ideas or insights. Despite the importance of improvisation, computational tools to support discussion have focused on supporting a fixed repertoire of activities such as multiple choice assessment, idea gathering, ranking, or concept mapping. To support the moves involved in improvisation, we theorize the need for playful, participation-oriented technologies. Such technologies must be highly flexible and support a range of representations, e.g., not just text but sketches and domain-specific notation. Meta-processes for improvisation impose an orthogonal requirement: the need to reflect on artifacts from new perspectives and then transform them into new representations. This project investigates roles that technology can play in a particular form of agile performance called "disciplined improvisation." In this work we will (1) develop a theoretical framework for supporting disciplined improvisation, (2) adapt a prototype classroom tool called "Group Scribbles" for the context of disciplined improvisation, and (3) investigate methods for iteratively evaluating systems for their degree of support for disciplined improvisation.Ultimately, this project aims to shed new light on how technology can assist us in real-time as we learn and solve problems with the people around us. We anticipate that our findings will lead to better software and hardware for classroom teachers and discussion facilitators more generally. This work builds on prior research into Computer Supported Cooperative Work, but breaks new ground by studying how computer-based tools can support the twists and turns of live performance.
