CollabWall: Understanding Collaborative Work with Interactive Display Walls in Multi-Device Environments

处理复杂的数据，根据多个信息源做出决策，以及越来越多的由多名专家组成的协作团队执行意义生成活动。例如肿瘤委员会审查，来自不同学科的医生在这里讨论患者数据以制定最佳治疗计划；控制室，在这里监测和分析各种传入信息流；或者战略和想法工程会议，人们在这里分析笔记、草图和其他媒体，以合作产生想法和目标。在所有这些和其他场景中，人们共处一处，相互协作，并越来越多地使用数字支持。在以前使用白板或单个显示器的地方，越来越多的设置将交互式大型墙壁显示器作为关注和团队讨论的中心。此外，移动个人设备（如笔记本电脑、平板电脑或智能手机）和水平桌面显示器正在所谓的多显示环境（MDE）中使用。我们预计这样的环境将成为未来计算机支持的协同协作的主要设置。在之前的研究中，已经为MDE提出了几种技术解决方案以及许多交互技术，例如在个人设备和大型墙壁显示器之间传输数据。然而，在这样的环境中，协作工作是如何完成的，个人工作和群体工作之间的转换是如何发生的，用户在MDE中扮演什么样的角色，如何、何地、何时显示感知信息，以及如何使用前面和墙上的空间显示，这些问题仍然缺乏系统和基础的理解。计划中的项目旨在缩小这一差距，并为更好地理解多显示环境中的协作交互做出重要贡献。在此基础上，我们将首先开发MDE协作影响维度的设计空间。接下来，为了更好地理解交互、移动和邻近模式，我们将开发一个新的MDE分析工具包，该工具包包含复杂的可视化视图，允许对记录的行为进行半自动分析。通过几项实证研究，我们将确定协作用户的行为模式，将研究重点放在空间使用、意识方面和动态变化的角色上。因此，我们将仔细制定设计指南，以促进MDE中未来协作用户界面的设计。因此，我们的项目既有理论贡献，也有实践贡献，因为可视化分析工具包和详细的研究数据将提供给其他研究人员。

Working with complex data, reaching decisions based on multiple information sources and sensemaking activities are increasingly executed by collaborative teams, which often consist of multiple experts. Examples are tumor board reviews, where doctors from different disciplines discuss patient data for optimal treatment planning, control rooms, where various incoming information streams are monitored and analyzed, or strategy and idea engineering meetings, where people analyze notes, sketches and other media to cooperatively generate ideas and objectives. In all these and other scenarios, people are co-located, collaborate with each other and make increasing use of digital support. Where previously whiteboards or single displays have been used, there is a growing number of setups with interactive large wall displays being the center of attention and team discussion. In addition, mobile personal devices, such as laptops, tablets or smartphones, and horizontal tabletop displays are being used in what has been termed a Multi-Display Environment (MDE). We expect such environments to be the dominate setup for computer-supported co-located collaboration in the future.In previous research, several technological solutions have been proposed for MDE as well as numerous interaction techniques, e.g., for transferring data between personal devices and large wall displays. However, a systematic and foundational understanding is still missing, how collaborative work is actually accomplished in such environments, how the transition between individual and group work happens, which roles users take over in MDE, how, where and when awareness information shall be displayed and how the space in front of and on the wall display is being used. The planned project aims at closing this gap and contributing important steps to a better understanding of collaborative interaction in Multi-Display-Environments.As a basis, we will first develop a design space of influencing dimensions for MDE collaboration. Next, to better understand interaction, movement, and proxemic patterns, we will develop a novel MDE analysis toolkit comprising complex visualization views, which allows for a semi-automated analysis of recorded behavior. By conducting several empirical studies, we will then identify behavior patterns of collaborating users, focussing our research on the usage of space, awareness aspects and dynamically changing roles. As a result, we will carefully develop design guidelines, which facilitate the design of future collaborative user interfaces in MDE. Therefore, our project will both make theoretical contributions as well as practical ones, since the visual analysis toolkit and the detailed study data will be made available to other researchers.
