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

即兴创作是高效面对面讨论的一个标志，可以带来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一直专注于支持一系列固定的活动，如多项选择评估、想法收集、排名或概念图。为了支持即兴创作中涉及的动作，我们理论上需要有趣的，以参与为导向的技术。这种技术必须高度灵活，并支持一系列表示，例如，不仅仅是文本，还有草图和特定领域的符号。即兴创作的元过程强加了一个正交要求：需要从新的角度反思工件，然后将其转换为新的表示。这个项目调查了技术在一种特殊的敏捷表现形式中扮演的角色，这种形式被称为“有纪律的即兴创作”。“在这项工作中，我们将（1）开发一个支持纪律即兴的理论框架，（2）为纪律即兴的背景调整一个名为“小组涂鸦”的原型课堂工具，（3）研究迭代评估系统对纪律即兴的支持程度的方法。最终，该项目旨在揭示新的技术如何帮助我们实时学习和解决我们周围的人的问题。我们预计，我们的研究结果将导致更好的软件和硬件的课堂教师和讨论主持人更普遍。这项工作建立在以前的研究计算机支持的合作工作，但通过研究如何基于计算机的工具可以支持现场表演的曲折开辟了新的天地。

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.
