抽象的。尽管二维(2D)地图现在无处不在，但作为另一种选择，城市的照片逼真三维(3D)表示(例如Google Earth)已经获得了科学家和公众用户的极大关注。然而，关于3D照片真实感对行人导航的影响，还没有一致的证据。与传统的符号化2D地图相比，3D照片真实感能否以更高的效率和更高的效率传达导航地图信息，以及更低的认知工作量，目前尚不清楚。本研究旨在探讨以实验室为基础的视线追踪方法，探讨照片真实感的3D呈现方式是否能促进数字环境中的地图阅读和导航过程。在这里，我们展示了符号化2D地图与照片级真实感3D地图的区别，这取决于用户的眼球运动和导航行为数据。我们发现，与使用2D地图阅读地图相比，使用3D表示的参与者效率更低，效率更低，并且需要更高的认知工作量。然而，使用3D表征的参与者在复杂决策点的自我定位和定向方面表现得更有效。研究结果将有助于提高步行导航地图在未来设计中的可用性。
Abstract. Despite the now-ubiquitous two-dimensional (2D) maps, photorealistic three-dimensional (3D) representations of cities (e.g., Google Earth) have gained much attention by scientists and public users as another option. However, there is no consistent evidence on the influences of 3D photorealism on pedestrian navigation. Whether 3D photorealism can communicate cartographic information for navigation with higher effectiveness and efficiency and lower cognitive workload compared to the traditional symbolic 2D maps remains unknown. This study aims to explore whether the photorealistic 3D representation can facilitate processes of map reading and navigation in digital environments using a lab-based eye tracking approach. Here we show the differences of symbolic 2D maps versus photorealistic 3D representations depending on users’ eye-movement and navigation behaviour data. We found that the participants using the 3D representation were less effective, less efficient and were required higher cognitive workload than using the 2D map for map reading. However, participants using the 3D representation performed more efficiently in self-localization and orientation at the complex decision points. The empirical results can be helpful to improve the usability of pedestrian navigation maps in future designs.
