We reviewed studies of viewers' reactions to stereoscopic image sequences. The dimensions considered were perceived image quality, sharpness, depth and naturalness. Stereoscopic displays produced a reliable and consistent increase in the perceived depth of image sequences. By comparison, improvements on other dimensions were not as robust. The key conclusion is that viewers' responses to stereoscopic image sequences vary along a number of independent dimensions. Overall preference for stereoscopic images will occur only if the enhanced depth perceived in a stereoscopic image sequence is not accompanied by distortions created by excessive disparity, ghosting/crosstalk, or conflicts between monoscopic and stereoscopic depth information.
