Stereoscopic perception of real depths at large distances.
There has been no direct examination of stereoscopic depth perception at very large observation distances and depths. We measured perceptions of depth magnitude at distances where it is frequently reported without evidence that stereopsis is non-functional. We adapted methods pioneered at distances up to 9 m by R. S. Allison, B. J. Gillam, and E. Vecellio (2009) for use in a 381-m-long railway ...
متن کاملDepth Perception and Visual After-effects at Stereoscopic Workbench Displays
The vivid and clear way of virtual scene presentation in Virtual Environments (VE) is nearly exclusively accomplished by stereoscopic displays. Depth perception with these displays differs from the viewing conditions in reality and causes usability problems. For this reason three important aspects of visualization at a stereoscopic workbench display were analyzed. The results of three experimen...
متن کاملStereoscopic Depth Perception during Binocular Rivalry
When we view nearby objects, we generate appreciably different retinal images in each eye. Despite this, the visual system can combine these different images to generate a unified view that is distinct from the perception generated from either eye alone (stereopsis). However, there are occasions when the images in the two eyes are too disparate to fuse. Instead, they alternate in perceptual dom...
متن کاملDefaults in stereoscopic and kinetic depth perception.
This study presents three findings concerning the mechanisms of depth perception. First, the shape of the three-dimensional percept evoked by two-frame motion is defined solely by the rotation component around an axis in the frontoparallel plane; the visual system assigns a default value to this rotation component to arrive at a unique solution. Second, when the visual axes of two eyes are almo...
متن کاملStereoscopic depth perception from oblique phase disparities
In order to understand the role of oblique retinal image disparities in the perception of stereoscopic depth, we measured the depth perceived from random dot stereograms in which phase disparities were introduced in a selected band of stimulus orientations. A band of orientation was defined by a center orientation that ranged from 7.5 (near vertical) to 82.5 o[rientation]deg and by a bandwidth ...
