GESTALT PRINCIPESop basis van: http://www.slideshare.net/jandot/intro-to-data-visualization


Gestalt - Principle of Simplicity

• Every pattern we see is seen such that we see a structure that is as simple as possible.


Gestalt - Principle of Proximity

• Things that are close to each other are seen as belonging together(=> clusters)


Gestalt - Principle of Similarity

• Things that are similar in some way are perceived as belongingtogether.


Gestalt - Principle of Closure

• You will try to complete a pattern.


Gestalt - Principle of Connectedness

• Things that are connected are perceived as belonging together. This encoding is stronger than similarity, shape, colour, and size.


Gestalt - Principle of Good Continuation

• Objects will be grouped as a whole if they are co-linear, or follow a direction (Chang, 2002; Lyons, 2001).


Gestalt - Principle of Familiarity






Gestalt - Principle of Symmetry


• Objects must be balanced or symmetrical to be seen as complete or whole (Chang, 2002).

Gestalt - Principle of Isomorphism


• Is similarity that can be behavioural or perceptual, and can be a response based on the viewers previous experiences (Luchins & Luchins, 1999; Chang, 2002). This law is the basis for symbolism(Schamber, 1986).
