In many domains increased collaboration has lead to more innovation by fostering the sharing of knowledge, skills, and ideas. Shared analysis of information visualizations does not only lead to increased information processing power, but team members can also share, negotiate, and discuss their views and interpretations on a dataset and contribute unique perspectives on a given problem. Designing technologies to support collaboration around information visualizations poses special challenges and relatively few systems have been designed. We focus on supporting small groups collaborating around information visualizations in a co-located setting, using a shared interactive tabletop display. We introduce an analysis of challenges and requirements for the design of co-located collaborative information visualization systems. We then present a new system that facilitates hierarchical data comparison tasks for this type of collaborative work. Our system supports multi-user input, shared and individual views on the hierarchical data visualization, flexible use of representations, and flexible workspace organization to facilitate group work around visualizations.
在许多领域，加强协作通过促进知识、技能和想法的共享带来了更多创新。对信息可视化进行共享分析不仅能提高信息处理能力，团队成员还能就数据集分享、协商和讨论他们的观点及解读，并为给定问题贡献独特视角。设计支持围绕信息可视化进行协作的技术面临特殊挑战，且设计出的系统相对较少。我们专注于使用共享交互式桌面显示器，支持在同一地点的小团体围绕信息可视化进行协作。我们对设计同一地点协作式信息可视化系统的挑战和要求进行了分析。然后我们展示了一个新系统，该系统有助于为这类协作工作执行分层数据比较任务。我们的系统支持多用户输入、对分层数据可视化的共享和个人视图、灵活使用表示方式以及灵活的工作空间组织，以促进围绕可视化的团队协作。
