2
‘rules’ that we apply to visual information to assist our organization and interpretation of the information in consistent meaningful ways.
3
When we need to organize or make sense of something in our visual field When something is inconsistent or incomplete Is it a conscious effort to do this? Not usually.
4
Advertising to distract you Painting for depth and texture cues Different colour road work signs to make sure they stand out.
5
Gestult Principles Depth Principles Perceptual Consistancies
6
A German word meaning form or shape Gestalt principles of visual perception refer to the ways in which we organise the features of a visual scene by grouping them to perceive a whole, complete form. Gestalt principles help us construct a meaningful whole object from an assortment of parts that, when considered as individual bits, lack any real meaning.
7
Figure Ground Organisation Closure Similarity Proximity
8
The viewer classifies the information in the visual field so that prominent and relevant stimulus is identified against plainer surroundings Figure – the prominent in the centre of our focus Ground – the back ground or plainer stimulus. Separated by a line called a contour Face or vase?
9
Separated by a line called a contour A type of perceptual organization that involves distinguishing edges of regions for the purpose of shape determination and determination of shape across an edge.
10
Traffic signs Reading Looking at photographs M.C. Escher’s paintings When the figure could be the ground and the ground could be the figure it is said to be REVERSIBLE (M. C. Escher) CAMOFLAGE occurs when figure and ground are not easily separated (Emma Hack)
13
the perceptual tendency to mentally ‘close up’, fill in or ignore gaps in a visual image and to perceive objects as complete (‘whole’)
15
the tendency to perceive parts of a visual image that have similar features such as size, shape, Texture Colour as belonging together in a unit, group or ‘whole’. (are the vertical or horizontal lines more prominent?)
16
Any type of uniform
17
The tendency to perceive parts of a visual image which are positioned close together as belonging together in a group. When stimuli are located near one another they are perceived as belonging together.
18
In proximity the bigger picture or group is made up of smaller individual pieces. The larger group is called the global level The individual pieces is the local level. On the left the global and Local letters are the same. On the right the global and Local letters are different.
