视觉编码是信息被显示、感知、解释并最终从可视化传输到用户的媒介。传统上，这种编码将信息显示为长度、颜色、大小、斜率、位置和其他字形的表示。已经提出了这种编码的指导方针，但它们通常假设小的显示器，小的数据集和相对静态的用户。大型高分辨率可视化能够同时显示更多信息，允许用户利用物理导航（移动）作为探索数据空间的有效交互。在本文中，我们分析了大型，高分辨率的可视化的视觉编码的选择是否以及如何影响物理导航，并最终为空间信息可视化任务的任务性能。
Visual encodings are the medium through which information is displayed, perceived, interpreted, and finally transferred from a visualization to the user. Traditionally, such encodings display information as representations of length, color, size, slope, position, and other glyphs. Guidelines for such encodings have been proposed, but they generally assume a small display, small datasets, and a relatively static user. Large, high-resolution visualizations are able to display far more information simultaneously, allowing users to leverage physical navigation (movement) as an effective interaction through which to explore the data space. In this paper, we analyze if and how the choice of visual encodings for large, high-resolution visualizations affects physical navigation, and ultimately task performance for a spatial information visualization task.
