This paper describes how the screen size of 3D displays affect the subjective impressions of 3D-visualized content. The key requirement for 3D displays is the presentation of depth cues comprising binocular disparities and/or motion parallax; however, the development of displays and production of content that include these cues leads to an increase in costs. Given the variety of screen sizes, it is expected that 3D characteristics are experienced differently by viewers depending on the screen size. We asked 48 participants to evaluate the 3D experience when using three different-sized stereoscopic displays (11.5, 55, and 200 inches) with head trackers. The participants were asked to score presented stimuli on 20 opposite-term pairs based on the semantic differential method after viewing each of six stimuli. Using factor analysis, we extracted three principal factors: power, related to strong three-dimensionality, real, etc.; visibility, related to stable, natural, etc.; and space, related to agile, open, etc., which had proportions of variances of 0.317, 0.277, and 0.251, respectively; their cumulation was 0.844. We confirmed that the three different-sized displays did not produce the same subjective impressions of the 3D characteristics. In particular, on the small-sized display, we found larger effects on power and space impressions from motion parallax (η² = 0.133 and 0.161, respectively) than for the other two sizes. We found degradation of the visibility impressions from binocular disparities, which might be caused by artifacts from stereoscopy. The effects of 3D viewing on subjective impression depends on the display size, and small-sized displays offer the largest benefits by adding 3D characteristics to 2D visualization.

本文介绍了 3D 显示器的屏幕尺寸如何影响 3D 可视化内容的主观印象。3D 显示器的关键要求是呈现包含双眼视差和/或运动视差的深度提示；然而，包含这些提示的显示器的开发和内容的制作会导致成本增加。鉴于屏幕尺寸的多样性，预计观看者对 3D 特性的体验会因屏幕尺寸而异。我们要求 48 位参与者评估使用三个不同尺寸的立体显示器（11.5、55 和 200 英寸）和头部跟踪器时的 3D 体验。参与者被要求在查看六个刺激中的每一个后，根据语义差异法对 20 个相反术语对上的刺激进行评分。使用因子分析，power，与强三维、真实等有关；能见度，与稳定、自然等有关；和space，与敏捷、开放等相关，方差比例分别为 0.317、0.277 和 0.251；他们的累积是 0.844。我们确认三种不同尺寸的显示器不会产生相同的 3D 特征主观印象。特别是在小型显示器上，我们发现运动视差对功率和空间印象的影响更大（η ²= 0.133 和 0.161，分别）比其他两种尺寸。我们发现双目视差会降低可见度印象，这可能是由立体镜的伪影引起的。3D 观看对主观印象的影响取决于显示器尺寸，而小型显示器通过在 2D 可视化中添加 3D 特征来提供最大的好处。
