投影策略和入侵自适应对保持拓扑的离屏可视化的影响
Topology-Preserving Off-screen Visualization: Effects of Projection Strategy and Intrusion Adaption
摘要：
随着越来越多的数据在大型信息空间中可视化，提供数据驱动上下文的方法变得不可或缺。因此，离屏可视化技术已经被广泛研究，因为它们能够克服概述和细节之间固有的权衡。一般的想法是将屏幕外定位的对象投影回可用的屏幕空间。分离的视觉线索，如光环或箭头，编码的位置和距离的信息，但不足以显示屏幕外对象的拓扑结构。出于该原因，现有技术将视觉提示集成到专用边界区域中。到目前为止，导航空间的尺寸没有得到适当的反映，这就是为什么我们建议根据空间位置调整边界的侵入。此外，屏幕外对象使用两种投影方法之一投影到边界区域：径向或正交。我们描述了一个对照实验，调查的效果，自适应边界入侵的拓扑结构以及用户的直觉，关于投影策略。实验结果表明，在自适应边界设计中，对不连通的点数据使用正投影策略。我们进一步讨论的结果，包括参与者的非正式反馈。
英文摘要：
With the increasing amount of data being visualized in large information spaces, methods providing data-driven context have become indispensable. Off-screen visualization techniques, therefore, have been extensively researched for their ability to overcome the inherent trade-off between overview and detail. The general idea is to project off-screen located objects back to the available screen real estate. Detached visual cues, such as halos or arrows, encode information on position and distance, but fall short showing the topology of off-screen objects. For that reason, state of the art techniques integrate visual cues into a dedicated border region. As yet, the dimensions of the navigated space are not reflected properly, which is why we propose to adapt the intrusion of the border pursuant to the position in space. Moreover, off-screen objects are projected to the border region using one out of two projection methods: Radial or Orthographic. We describe a controlled experiment to investigate the effect of the adaptive border intrusion to the topology as well as the users' intuition regarding the projection strategy. The results of our experiment suggest to use the orthographic projection strategy for unconnected point data in an adaptive border design. We further discuss the results including the given informal feedback of participants.
