GestaltLaws of Organization(Perceptual Organization)Gestaltis a psychology term which means "unified whole". It refers to theories ofvisual perceptiondeveloped by German psychologists. These theories attempt to describe how people tend to organize visual elements intogroupsorunified wholeswhen certain principles are appliedSix main factors that determine how the visual system groups elements into patternsFigure-Ground PerceptionProximity SimilarityContinuityClosureConnectednessFigure-Ground Perceptionis a type of perceptual grouping which is a vital necessity for recognizing objects through vision. InGestalt psychologyit is known as identifying afigurefrom the background. For example, you see words on a printed paper as the "figure" and the white sheet as the "background

ProximityProximityoccurs when elements are placed close together. They tend to be perceived as a group.Example

SimilaritySimilarityoccurs whenobjects look similarto one another. People often perceive them as a group or pattern.Example

ContinuityContinuity occurs when the eye is compelled tomove throughone object andcontinueto another object.Example

Continuation occurs in the example above, becausethe viewer's eye will naturally follow a line or curve.The smooth flowing crossbar of the "H" leads the eye directly to the maple leaf.ClosureClosureoccurs when an object isincompleteor a space is notcompletely enclosed. If enough of the shape is indicated, people perceive the whole by filling in the missing information.Example

Although the panda above is not complete, enough is present for the eye to complete the shape. When the viewer's perception completes a shape,closureoccurs.ConnectednessWe perceive spots, lines or areas as a single unit when uniform and linkedExample

Movement PerceptionMoving objects whether they are people, animals, cars, or tress of Earth plummeting down a hillside is called as real movement or motion. However, psychologists have studied several types of apparent movement, or illusions of movement. These include the following:Auto Kinetic EffectStroboscopic MotionPhi-PhenomenonAuto kinetic Effectillusory movement of a single still object, usually a stationary pinpoint of light used in psychology experiments in dark rooms. As one stares at a fixed point of light, ones eye muscles become fatigued, causing a slight eye movement. Without the usual reference points available in the everyday environment, the movement of the image on the retina isperceivedas its actual movement in space.Stroboscopic Motionis a visual phenomenon caused by aliasing that occurs when continuous motionis represented by a series of short or instantaneous samples.Phi-Phenomenonis the optical illusion of perceiving continuous motion between separate objects viewed rapidly in succession.Depth PerceptionThe termdepth perceptionrefers to our ability to determine distances between objects and see the world in three dimensions.Two types of CuesMonocular(using one eye)Binocular(using two eye)
