- Updated April 14, 2017. Depth perception is the ability to perceive the world in three dimensions (3D) and to judge the distance of objects. Depth perception is achieved when the brain processes different pictures from each eye and combines them to form a single 3-D image.

- Visual perception is the ability to see and interpret (analyze and give meaning to) the visual information that surrounds us. The process of taking in one's environment is referred to as perception. If perception is inaccurate, incorrect or altered in any way - problems with reading, spelling, handwriting, math and comprehension occur.

Sight Distance and Reaction Time Sight Distance. 1  Sight distance means the distance from which you can see and identify a hazard. You often see an object before you’re able to identify it as a hazard. 2  If the stopping distance to an object is greater than the sight distance, you’re in danger of hitting the object.

Low Vision Assessment and Rehabilitation Visual Acuity Notation. Visual acuity is the ability to see and discriminate a certain size target at a specified distance. Distance vision can be measured by various methods, but basically looks like a fraction, e.g. 20/20, 20/200. The first figure (numerator) records the distance at which the testing was done (in feet).

Perception and Its Influence on Individual Behaviour Perceptual Set: Perception, as we have defined, is a generic term for the complex sensory control of behaviour. It is inferred from a hypothetical internal event of unspecified nature, controlled largely by external stimulation and variables such as habit and drive. Therefore, it is appropriate to state that people tend to perceive what they expect to perceive.

What Does Visual Lead Time Mean? The visual lead time is the distance of attention that a driver should pay attention to. The driver should anticipate traffic movement and potential hazards for the visual lead time. This includes scanning sidewalks and the road while making adjustments to the car's speed or position as necessary.

Perception of Depth by Michael Kalloniatis and Charles Luu Perception of Depth by Michael Kalloniatis and Charles Luu. Stereopsis refers to our ability to appreciate depth, that is the ability to distinguish the relative distance of objects with an apparent physical displacement between the objects. It is possible to appreciate the relative location of objects using one eye (monocular cues).
