The sense of discomfort when watching stereoscopic display caused by visual fatigue has hindered the widespread applications of stereoscopic display. In this work, we explore the relationship between visual fatigue and stereoscopic parallax using subjective assessment. The visual fatigue of the subjects is evaluated after viewing different parallax stereoscopic samples. It shows that visual fatigue exacerbates greater in negative parallax than positive parallax. Surprisingly, the results indicate that visual fatigue can be alleviated with tiny parallax, which increases the comfort of stereoscopic visual perception. We envision that this relationship is able to provide helpful hints in designing visual healthy stereoscopic images.

视觉疲劳与立体视差的主观评估

视觉疲劳导致观看立体显示时的不适感，阻碍了立体显示的广泛应用。在这项工作中，我们使用主观评估来探索视觉疲劳与立体视差之间的关系。观察不同视差立体样本后评估受试者的视觉疲劳。这表明负视差比正视差更严重地加剧视觉疲劳。令人惊讶的是，结果表明，微小的视差可以缓解视觉疲劳，增加立体视觉的舒适度。我们设想这种关系能够为设计视觉健康的立体图像提供有用的提示。
