Abstract Drawing is a powerful tool for industrial designers when presenting the potential of an idea to convince viewers. Thus, they should have an increased understanding of perspective drawing techniques. These techniques may still cause miscommunication between designers and viewers even though they are applied correctly. The present study examines whether the perspective drawing techniques in terms of eye-level positions and view-angle choices, influence the viewers’ ability to identify the drawn-objects accurately. Results reveal that the identification accuracy in one-point and two-point perspective techniques is found dissimilar between different eye-level positions. Drawings generated at 20° to 50° of view-angles with one-point, and 10° to 20° of view-angles with two-point perspective, are perceived more accurately compared to other view-angles. Results partially conflict with the guidelines suggested by the literature. Findings of the study are relevant for designer practitioners, researchers, educators, and students when creating design drawings carrying high communication value.

透视图的感知：关于选择视线和视角的原则的争论

对于工业设计师而言，抽象绘画是一种功能强大的工具，它可以展现一种想法来说服观众。因此，他们应该对透视图绘制技术有更多的了解。即使正确应用了这些技术，它们仍然可能导致设计者和查看者之间的沟通不畅。本研究从视线水平位置和视角选择方面检查透视图绘制技术是否会影响观看者准确识别绘制对象的能力。结果表明，在不同眼睛水平位置之间，发现了单点和两点透视技术的识别准确度不同。以20°到50°的单点视角和10°到20°的单点视角生成的工程图，与其他视角相比，可以更准确地感知。结果与文献中提出的指导原则部分冲突。研究结果与设计师从业人员，研究人员，教育工作者和学生在制作具有较高交流价值的设计图时相关。
