VISUAL DISPARITY Meaning and
Definition
-
Visual disparity refers to the discrepancy or difference between what the eyes see or perceive in terms of the position or orientation of objects or stimuli. It is a phenomenon that emerges due to the spatial separation of the eyes, causing each eye to have a slightly different perspective on the visual scene.
The human visual system relies on this visual disparity or binocular disparity as a powerful cue for depth perception and determining the spatial relationships between objects in a three-dimensional space. Visual disparity occurs because the eyes are positioned apart from each other, resulting in two slightly different images that are captured by each eye. These two separate images are then processed by the brain, which integrates them to create a single, unified perceptual image.
Visual disparity can vary depending on the distance or location of objects in the visual field. When objects are close to the observer, the visual disparity is greater, allowing for more accurate depth perception and perception of the object's three-dimensional structure. Conversely, as objects move further away, the visual disparity decreases, and the depth cues relying on other factors such as relative size, perspective, and shading become more prominent.
The brain's ability to process the visual disparity and integrate the visual information from both eyes provides humans with a sense of depth and allows for precise spatial perception. Understanding and studying visual disparity can have applications in various fields, such as virtual reality, stereoscopic displays, and medical imaging, where accurate depth perception is crucial for realistic and immersive visual experiences or precise diagnosis and treatment planning.

Etymology of VISUAL DISPARITY
The word "visual" is derived from the Latin word "visus", which means "sight" or "vision". "Disparity" comes from the Latin word "disparitas", meaning "difference" or "unequal". Therefore, the term "visual disparity" refers to a difference or inequality in vision or sight.
