Abstract The vertical parallax of both eyes, caused by tilting the head when watching three-dimensional (3D) television or movies, can induce visual fatigue or visually-induced motion sickness. The purpose of the present study was to investigate levels of discomfort and fatigue and eye movements induced by viewing a 3D movie with vertical parallax. Two experiments were conducted to investigate the relationship between the degree of vertical parallax and the magnitude of the effect. The results indicate that the viewer’s feeling of visual malaise increases as the angle of the screen increases, with respect to the observer’s head, because eye movement does not compensate for the parallax in the vertical direction. Binocular rivalry is believed to occur when viewing a 3D movie with vertical parallax, which may induce even more visual malaise.

观看具有垂直视差的 3D 电影的效果

摘要 观看三维（3D）电视或电影时，由于头部倾斜而引起的双眼垂直视差会引起视觉疲劳或视觉诱发的晕车。本研究的目的是调查因观看具有垂直视差的 3D 电影而引起的不适、疲劳和眼球运动的程度。进行了两个实验来研究垂直视差程度与效果大小之间的关系。结果表明，相对于观察者的头部，随着屏幕角度的增加，观看者的视觉不适感也会增加，因为眼球运动无法补偿垂直方向的视差。人们认为在观看具有垂直视差的 3D 电影时会发生双眼竞争，这可能会导致更多的视觉不适。
