Each visual stimulus in (a) and (b) includes two gray meteor objects: one meteor object was intended to induce visual discomfort due to excessive screen disparities (i.e., disparity-induced discomfort), while the other meteor object was intended to induce visual discomfort due to fast changes of disparity (i.e., motion-induced discomfort). The lateral distances between centers of the two meteor objects were set to (a) 5 deg and (b) 15 deg, respectively. The figure (c) is the magnified version of a meteor object and figure (d) illustrates the presentation of synthetic simple scenes in our experimental environment.

The x-axis indicates the disparity magnitude and the y-axis indicates the in-depth motion velocity. Note that the units of the x-axis and y-axis are the angular disparity (deg) and the change of angular disparity (deg/s), respectively.

The first and second columns correspond to examples of animated scenes, and the other columns correspond to examples of natural scenes. Note that these scenes contain various living and nonliving entities in diverse places, such as humans, man-made objects, etc. Figure Legend: From: Experimental investigation of discomfort combination: toward visual discomfort prediction for stereoscopic videos J.

The abscissa represents the content index and the ordinate represents the normalized comfort scale, respectively. The error bars represent the 95% confidence interval. Note that higher nMOS represents more uncomfortable. Figure Legend: From: Experimental investigation of discomfort combination: toward visual discomfort prediction for stereoscopic videos J.
