了解用户如何感知3D几何对象可以为在CAD或医学成像等应用程序中创建更有效的可视化工具提供基础。本文研究了方位指示器如何影响用户感知显示为多个视图的3D对象的形状的准确性。多个视图迫使用户推断对象的方向，并识别不同有利位置之间的对应特征。这些都是困难的任务，并不是所有的用户都能准确地完成它们。我们使用认知实验范式来评估两种类型的取向指示器对一个人比较不同取向对象的观点的能力的有效性。实现的方向指示器是与3D对象共享中心点的同位指示器，或者与3D对象不同位置(从3D对象移位)的方向指示器。这项研究还考虑了其他因素，包括物体的复杂性、旋转轴以及用户在空间能力上的个体差异。我们的结果表明，方位指示器有助于用户比较多个视图，并且其效果受到辅助类型、人的空间能力和任务难度的影响。除了建立定向指标的作用外，本文还帮助演示了特定实验范式和分析的应用，以及在设计界面辅助工具时考虑个体差异的重要性。
Understanding how users perceive 3D geometric objects can provide a basis for creating more effective tools for visualization in applications such as CAD or medical imaging. This article examines how orientation indicators affect users' accuracy in perceiving the shape of a 3D object shown as multiple views. Multiple views force users to infer the orientation of an object and recognize corresponding features between distinct vantage points. These are difficult tasks, and not all users are able to carry them out accurately. We use a cognitive experimental paradigm to evaluate the effectiveness of two types of orientation indicators on a person's ability to compare views of objects presented in different orientations. The orientation indicators implemented were colocated, which shared a center-point with the 3D object, or noncolocated with (displaced from) the 3D object. The study accounts for additional factors including object complexity, axis of rotation, and users' individual differences in spatial abilities. Our results show that an orientation indicator helps users in comparing multiple views, and that the effect is influenced by the type of aid, a person's spatial ability, and the difficulty of the task. In addition to establishing an effect of an orientation indicator, this article helps demonstrate the application of a particular experimental paradigm and analysis, as well as the importance of considering individual differences when designing interface aids.
