Consistent stereoscopic information increases the perceived speed of vection in depth.
Previous research found that adding stereoscopic information to radially expanding optic flow decreased vection onsets and increased vection durations (Palmisano, 1996 Perception & Psychophysics 58 1168-1176). In the current experiments, stereoscopic cues were also found to increase perceptions of vection speed and self-displacement during vection in depth--but only when these cues were consist...
متن کاملThe Role of Perceived Speed in Vection: Does Perceived Speed Modulate the Jitter and Oscillation Advantages?
Illusory self-motion ('vection') in depth is strongly enhanced when horizontal/vertical simulated viewpoint oscillation is added to optic flow inducing displays; a similar effect is found for simulated viewpoint jitter. The underlying cause of these oscillation and jitter advantages for vection is still unknown. Here we investigate the possibility that perceived speed of motion in depth (MID) p...
متن کاملControlling Perceived Depth in Stereoscopic Images
Stereoscopic images are hard to get right, and comfortable images are often only produced after repeated trial and error. The main difficulty is controlling the stereoscopic camera parameters so that the viewer does not experience eye strain or double images from excessive perceived depth. Additionally, for head tracked displays, the perceived objects can distort as the viewer moves to look aro...
متن کاملDisparity-energy signals in perceived stereoscopic depth.
Stereopsis, the ability to sense the world in three dimensions (3D) from pairs of retinal images, functions when both images have corresponding elements. When observers view stereograms lacking a global match, they do not perceive 3D structure, whereas several cortical areas encode stereoscopic depth in the disparity energy. Whether these neural representations are exploited or ignored in perce...
متن کاملVection in depth during consistent and inconsistent multisensory stimulation.
We examined vection induced during physical or simulated head oscillation along either the horizontal or depth axis. In the first two experiments, during active conditions, subjects viewed radial-flow displays which simulated viewpoint oscillation that was either in-phase or out-of-phase with their own tracked head movements. In passive conditions, stationary subjects viewed playbacks of displa...
