2D 和 3D 视图在许多可视化领域中一起使用,例如医学成像、流动可视化、海洋学可视化和计算机辅助设计 (CAD)。将这些视图组合到一个显示中可以通过以下方式完成:(1) 方向图标(即单独的窗口),(2) 就地方法(例如,剪辑和切割平面),以及 (3) 一种称为 ExoVis 的新方法。 2D 和 3D 视图的显示方式会影响心理注册的难易程度(理解视图之间的空间关系),这是影响用户性能的重要因素。本文从支持心理登记的能力方面对上述方法进行了比较。经验结果表明,使用就地显示比使用 ExoVis 更容易进行心理记录,并且使用 ExoVis 比使用方向图标更容易。不同的心理转变策略可以解释这一结果。结果表明,当就地显示不合适时(例如,当就地方法隐藏数据或将 3D 视图切割成多个部分时),ExoVis 可能是方向图标的更好替代方案。
2D and 3D views are used together in many visualization domains, such as medical imaging, flow visualization, oceanographic visualization, and computer aided design (CAD). Combining these views into one display can be done by: (1) orientation icon (i.e., separate windows), (2) in-place methods (e.g., clip and cutting planes), and (3) a new method called ExoVis. How 2D and 3D views are displayed affects ease of mental registration (understanding the spatial relationship between views), an important factor influencing user performance. This paper compares the above methods in terms of their ability to support mental registration. Empirical results show that mental registration is significantly easier with in-place displays than with ExoVis, and significantly easier with ExoVis than with orientation icons. Different mental transformation strategies can explain this result. The results suggest that ExoVis may be a better alternative to orientation icons when in-place displays are not appropriate (e.g., when in-place methods hide data or cut the 3D view into several pieces).
