Combination of Binocular Disparity and Motion Parallax Does Not Contribute to the Fixing of Depth Reversal
The visual phenomenon that perceived depth sign is opposite to depth sign geometrically predicted from binocular disparity or motion parallax is known as depth reversal (Gillam, 1967; Hayashibe, 1991). Combination of binocular disparity and motion parallax generally improve depth perception (Nawrot...

description | The visual phenomenon that perceived depth sign is opposite to depth sign geometrically predicted from binocular disparity or motion parallax is known as depth reversal (Gillam, 1967; Hayashibe, 1991). Combination of binocular disparity and motion parallax generally improve depth perception (Nawrot & Blake, 1991). In the current study, we investigated if the combined display contributes to the fixing of depth reversal. In a dark room, a surface slanted about a vertical axis was displayed for 800 ms by binocular cue only, by motion cue only, or by binocular and motion cues. Six subjects judged the apparent slant. Overall, mean frequencies of reports of reverse slant were 78.2%, 36.8%, and 78.6% for binocular cue only, motion cue only, and binocular and motion cues, respectively. Namely, combination of binocular disparity and motion parallax does not contribute to the fixing of depth reversal. |
