Binocular disparity is of vital importance in stereoscopic vision. It determines the depth magnitude and effects the impression formation when human watch three-dimensional things. However so far how binocular disparity activates the brain regions hasn't got consistent conclusions. So a fMRI(functional magnetic resonance imaging) experiment was designed to locate cortex areas related with stereoscopic...
Purpose: To identify the regions responding to the stereoscopic motion induced by binocular disparity and investigate the relationship between the response intensity of these regions and speeds of spatial motion. Methods: The stereoscopic stimulus applied Random Dot Stereogram (RDS) distributed as checkerboard and a series of continuous disparities formed a dynamic stereoscopic stimulus. Observer...
The visual fatigue is a common question in stereoscopic image observation based on parallax, and the essential reason is that convergence and focus adjustment are inconsistent, which violates the principe that convergence and focus adjustment are consistent in the real world. The paper explores the causes of visual fatigue in stereoscopic image observation by the visual physiology and psychology,...
