PERCEPTION OF SPACE DEPTH AND DISTANCE

One example is the photographic art exhibit called "the Family of Man"-503 pictures occupying some 8,000 Feet (2,700 meters) of wall space in New York's Museum of Art Planned and executed by Edward Steichen. A floor plan was made by Arch. Rudolph, which is a crucial step in determining the overall arrangement of pictures.

An important feature of perception of depth and solidity of objects is constituted by the shadows which are casts upon parts of them by the general illumination. Normally, shadows appear on the receding parts of objects and indicates recession and hence solidity. Changes in the appearance of depth can be produced by altering the direction of the incident light.

The perception of depth depends upon the direction of the light perceived, not on the physical direction of light. A concave relief (matrix) can reverse its depth and is then perceived as a convex (patrix).

PSYCHOLOGICAL FACTORS AFFECTING ACCURACY OF SHAPE PERCEPTION

End of Chapter 5

The simpler the actual shape which is viewed like squares, triangles, circles, the more likely it is to be perceived accurately, even though in a very short period of time.

Chapter 8: Space Articulation

Perception

-is the process by which we organize and interpret the patterns of stimuli in our environment, the immediate intuitive recognition, as of an aesthetic quality.

The separation of two lines placed end to end can be perceived more readily thsn separatetion of 2 lines placed side by side.

Spacial Perception

The Perception of Objects

-all spacial implications are mentally conditioned by the environmental and experience of the viewer. VISION is experienced through the eyes, but interpreted with the mind. Perception invovolves the whole pattern of nerve and brain response as well as the visual 'stimulus'.

Objects can be perceived not only visually but by the sound of familiar voices, people can be recognized. In identifying objects, they may be touched and weighed in the hand. If they are food objects, they may be smelt and tasted. Thus the observer may continue examining the object and placing together the various sensory impressions until he has made up his mind what it is.

-Eunice B. Ocampo from ARC13

2 Different Types of Vision

Perception of Shape

Stereoscopic- is applied to his inability to overlap these views, which are slightly different, into one image. This viual process created an illusion of three-dimensional depth. making it possible to judge distances.

Kinesthetic- man experiences space in the movements of the eye from one part of a whole work of art to another. Space is experienced while viewing a two-dimensional surface because we unconciously attempt to organize it's separate parts so that they can be seen as a whole. In addition, man explores objects surmental recognition of them. Objects close to the eye require more. Ocular movement then those more distant, and this factor adds spatch illusion to man's Kinesthetic vision.

The most important feature of a shape or object is its general outline or contour. With a solid object the particular contour exhibited to us at any one moment varies with its position in space. The visual shape of a square- topped table is square only when we look at it from above.

Fluctuation

Instances of fluctuation are given by the phenomena of alternating 'Figure' and 'Ground' alternating perspective and retinal rivalry.

"FIGUREGROUND"- a phenomenon wherein drawings consisting of black lines, any line which surrounds an area, and which is recognized as representing an object is quickly picked out by the observer, and it then seems to him to stand out from the background in an obvious manner.

Some part of it will always be "figural" and to be differentiated from the rest of the field which forms the "ground" to it's figure.

Vanity

When you look at this figure from afar it looks so much like a skull but when near, it clearly shows a lady in front of a mirror.
