This paper presents a tool for the visual analysis of navigation patterns of moving entities, such as users, virtual characters, or vehicles in 3D Virtual Environments (VEs). The tool, called VU-Flow, provides a set of interactive visualizations that highlight interesting navigation behaviors of single or groups of moving entities that were the VE together or separately. The visualizations help to improve the design of VEs and to study the navigation behavior of users, e.g., during controlled experiments. Besides VEs, the proposed techniques could also be applied to visualize real-world data recorded by positioning systems, allowing one to employ VU-Flow in domains such as urban planning, transportation, and emergency response.
本文介绍了一种用于可视化分析3D虚拟环境（VE）中移动实体（如用户、虚拟角色或车辆）导航模式的工具。该工具名为VU-Flow，提供了一组交互式可视化功能，可突出显示单个或成组移动实体在VE中一起或分别移动时的有趣导航行为。这些可视化有助于改进VE的设计，并研究用户的导航行为，例如在受控实验期间。除了VE，所提出的技术还可应用于可视化定位系统记录的现实世界数据，从而使VU-Flow能够应用于城市规划、交通和应急响应等领域。
