Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

We discuss a novel method forviewpoint-rotation of visual stimuli, and demonstrate using a mirror stereoscopethe three-dimensional percept of rotation-in-depth. The technique can be used to investigate the role of stereoscopic cues in encoding viewpoint-rotated figures.

Here we present a comprehensive battery of tasks to assess binocular vision. Tasks include peripheral stereoacuity and motion-in-depth, which are not assessed by current clinical tests. Incorporating these tasks will provide an in-depth assessment of an individual’s binocularity.

Perspectives on Sensation and Perception

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University The study of sensation—how signals are transduced from sensory organs, like the eyes—and perception—how the brain interprets these messages—has a rich history dating back to the 19th century, when great strides were made in understanding the properties of light and how they relate to the visual system. Importantly, such sensory and perceptual processes determine what we see, feel, taste, and hear in our surroundings. However, many...

FAQs
The brain uses binocular disparity, meaning the difference between the two retinal images, to infer spatial relationships. Because the eyes view a scene from slightly different angles, corresponding features do not appear in exactly the same location in each image. Comparing these differences helps the visual system estimate relative distance and the three-dimensional placement of objects.
Eye convergence and focusing provide additional cues that complement binocular disparity. Convergence reflects how the eyes coordinate their positioning, while focusing contributes information associated with viewing objects at different distances. The brain integrates these signals with the two retinal images to construct a depth estimate, making coordinated eye function important for accurate three-dimensional perception.
A depth estimate depends on coordinated information rather than a single visual signal. Binocular disparity supplies differences between the eyes’ views, while convergence and focusing add related information about visual distance. Integrating these cues allows the brain to organize the scene in three dimensions and judge the relative position of objects more effectively.
Clinical assessment can reveal problems with binocular function and eye coordination. Reduced or abnormal depth perception may help identify visual disorders such as strabismus, in which the eyes are not properly aligned, or amblyopia. These evaluations provide information about how effectively the visual system combines input from both eyes during three-dimensional viewing.
Depth-perception tests can support diagnosis and help clinicians monitor changes during treatment. Repeated assessment provides information about whether binocular function or eye coordination is improving, remaining impaired, or changing over time. This makes stereoscopic evaluation useful not only for initial characterization of a visual problem but also for tracking clinical progress.
Findings from depth-perception assessment can help guide visual rehabilitation by showing how well binocular information is being integrated. The same measures support research into sensory integration, the process by which the visual system combines information from multiple sources. Together, clinical and research uses connect measured visual performance with treatment planning and understanding of visual function.
