Do people compensate for incorrect viewing position when looking at stereograms?
” Perception 34 ECVP Abstract Supplement Do people compensate for incorrect viewing position when looking at stereograms? A R Girshick, M S Banks A conventional picture viewed from its centre of projection (CoP) produces the same retinal image as the original depicted scene. When viewed from another position, the retinal image specifies a different scene, but people typically perceive the original depicted scene, not the one specified by the retinal image. Thus, they compensate for incorrect viewing position. Compensation is based on a measurement of the slant of the picture surface, and the primary cue for the measurement is binocular disparity. Using disparity works because disparity signals the slant of the picture surface and is unaffected by the depicted 3-D contents of the picture. In stereograms, the disparity signals both the 3-D contents of the depicted scene and the slant of the picture surface. Here, we ask if observers compensate for incorrect viewing position with stereogr
