This study examined how tumbler characteristics influenced the perception of volume at different viewing angles. Three tumbler characteristics were individually examined, namely, shape, size, and elongation. At four viewing angles (0°, 30°, 60°, and 90°), 50 participants poured a certain amount of liquid (150 or 200 mL) into a designated tumbler according to their perception. Results showed that tumbler size and elongation influenced volume perception. At viewing angles of 0° and 30°, the participants poured more liquid into short-wide tumblers than into tall-slender tumblers. At viewing angles of 60° and 90°, the results were opposite. The reason may be that the change of viewing angle made the participant's sight cues from the container diameter more visible than those from the container height. Similar results were obtained for the pair of small and large tumblers. However, no effect of viewing angle on tumblers with different geometric shapes was observed. The contradictory results in comparison with those of previous studies may be related to viewing angle; in addition, the effect of viewing angle was also influenced by the characteristics of tumblers.
本研究考察了杯子特征如何在不同视角下影响体积感知。分别对三种杯子特征进行了考察，即形状、尺寸和细长比。在四个视角（0°、30°、60°和90°）下，50名参与者根据自己的感知向指定的杯子中倒入一定量的液体（150或200毫升）。结果表明，杯子的尺寸和细长比会影响体积感知。在0°和30°视角下，参与者向矮胖杯子中倒入的液体比向高瘦杯子中倒入的更多。在60°和90°视角下，结果则相反。原因可能是视角的变化使参与者从容器直径获得的视觉线索比从容器高度获得的更明显。对于一对大小不同的杯子也得到了类似的结果。然而，未观察到视角对具有不同几何形状的杯子有影响。与先前研究结果相矛盾可能与视角有关；此外，视角的影响也受杯子特征的影响。
