We introduce Tilt Map, a novel interaction technique for intuitively transitioning between 2D and 3D map visualisations in immersive environments. Our focus is visualising data associated with areal features on maps, for example, population density by state. Tilt Map transitions from 2D choropleth maps to 3D prism maps to 2D bar charts to overcome the limitations of each. Our paper includes two user studies. The first study compares subjects' task performance interpreting population density data using 2D choropleth maps and 3D prism maps in virtual reality (VR). We observed greater task accuracy with prism maps, but faster response times with choropleth maps. The complementarity of these views inspired our hybrid Tilt Map design. Our second study compares Tilt Map to: a side-by-side arrangement of the various views; and interactive toggling between views. The results indicate benefits for Tilt Map in user preference; and accuracy (versus side-by-side) and time (versus toggle).

倾斜图：沉浸式环境中等值线图、棱镜图和条形图之间的交互式转换

我们介绍了 Tilt Map，这是一种新颖的交互技术，用于在沉浸式环境中直观地在 2D 和 3D 地图可视化之间转换。我们的重点是可视化与地图上的区域特征相关的数据，例如各州的人口密度。倾斜图从 2D 等值线图到 3D 棱镜图再到 2D 条形图的转换，以克服每个图的局限性。我们的论文包括两项用户研究。第一项研究比较了受试者在虚拟现实 (VR) 中使用 2D 等值线图和 3D 棱镜图解释人口密度数据的任务表现。我们观察到棱镜图的任务精度更高，但等值线图的响应时间更快。这些视图的互补性启发了我们的混合倾斜地图设计。我们的第二项研究将倾斜地图与： 各种视图的并排排列；和视图之间的交互式切换。结果表明 Tilt Map 在用户偏好方面的优势；和准确性（与并排相比）和时间（与切换相比）。
