本文的目的是研究瞳孔直径的变化是否可以反映不同程度的局部三维图像以及其他验证特征的不适程度。此外，我们还讨论了这些系统在通过部分3D图像引导视觉注意力时的有效性。从IAPS（国际情感图像系统）中选择的图像用于制作3D图像。计算刺激图像与对照图像产生的瞳孔变化的功率谱比，即S/C值。投影影像印象VAS评分与S/C值之间的关系是本研究的主要关注点。因此，二维中性图像的平均S/C值为0.634 ~ 1.318，而部分三维中性图像的平均S/C值为0.412 ~ 1.552。2D中性图像VAS评分为3.6 ~ 8.5，部分3D中性图像VAS评分为1.2 ~ 7.4。2D中性影像VAS评分与S/C值的相关系数为0.116，部分3D中性影像VAS评分与S/C值的相关系数为- 0.114。在部分3D图像中，这种负相关系数与之前的研究一致，而两幅图像的相关系数都相对较低。建议在实验过程中修改VAS评分收集技术，S/C值可能作为不适测量的候选值。
The purpose of this paper was to examine whether the changes in pupil diameter can refrect on the degree of discomfort by various levels of partial 3D images as well as other validated characteristics. Moreover, we discuss the effectiveness of the systems while guiding visual attention by partial 3D images. Images chosen from IAPS (International Affective Picture System) were used to make 3D images. Power spectrum ratio of the pupil variation, called S/C value, generated by stimuli images to those by control images was calculated. The relationship between VAS scores for the impression regarding projected images and the S/C values was set to the major concern for this study. As a result, the average S/C values in 2D neutral images ranged 0.634 to 1.318, whereas the average S/C values in partial 3D neutral images ranged 0.412 to 1.552. VAS scores in 2D neutral images ranged 3.6 to 8.5 and that in partial 3D neutral images ranged 1.2 to 7.4. Moreover, correlation coefficients between VAS scores and S/C values in 2D neutral images was 0.116 and those in partial 3D neutral images was −0.114. In partial 3D images, this negative correlation coefficient was found in consistent with the previous study, whereas the correlation coefficients for both images were relatively low. It was suggested that S/C value was likely to use as a candidate for discomfort measure with a modification of collection technique for VAS scores during the experiment.
