Gestalt Principles of Visual Perception
Gestalt is a psychology term which means "unified whole". It refers
to theories of visual perception developed by German
psychologists in the 1920s. These theories attempt to describe how
people tend to organize visual elements into groups or unified
wholes when certain principles are applied.

 Gestalt – Movement in experimental
psychology which began prior to WWI.
 We perceive objects as well-organized
patterns rather than separate components.
 “The whole is greater than the sum of it’s
parts.”
 Based on the concept of “grouping”.

We impose visual organization on stimuli

Three Main Principles:
Grouping (proximity, similarity,
continuity, closure)
Goodness of figures
Figure/ground relationships

Grouping:
Law of Proximity

Grouping: Law of Similarity: Shape, Scale, Color

Law of Good Continuation, or
Continuity
Objects arranged in either a
straight line or a smooth
curve tend to be seen as a
unit.

Law of Closure

Law of Common Fate

Goodness of Figure, or the Law of Pragnanz
According to the Gestaltists, the whole stimulus pattern determines the
organization of its own parts. The Gestalt psychologists believed that all the
grouping laws are particular examples of one general principle- the law of
pragnanz. The law of pragnanz is a term to refer to the tendency to perceive
figures as good, regular, and simple with minimum cognitive effort. Therefore,
this law is also known as the law of good figure.

Figure/Ground relationships
Figure – seen as the foreground
Ground – seen as the background
Contours – “belong” to the figure

Reversible Figure/Ground
relationship

relationship
Can be affected by the
principle of smallness:
Smaller areas tend to be seen
as figures against a larger
background.

Relationship:
Tessellation – interlocking
figure/ground
M.C. Escher

 Gestalt laws of Grouping organize the
visual scene into units
 The Law of Pragnanz, or Goodness of
Figure creates the simplest most meaningful
pattern
 Figure/Ground relationships define
important parts of the scene

Problems with Gestalt theory:
It is a phenomenological approach
Some of the terms are vague

compositions
• Direction in visual design
• Texture

Elements of visual design
 This series of lectures is covering the
elements of visual design and while these
are primarily limited to dot, line, shape,
color and texture, there are other aspects
that are often considered as elements of
visual design. Space and direction are
seen as some of these by design
philosophers.

Space
 Space has to be included in any
visual design.
 In 2-dimensional arrangements space
means leaving some blank areas in a
composition.
 A human eye needs space to feel
comfortable, and space will let the
eye distinguish the part that's meant
to be noticed compared to just the
background.
 Sometimes not including space in a
visual design is acceptable, but care
has to be taken to ascertain that the
final visual effect is not over crowded
and chaotic.
ADT I 2006 Prof Anil Kumar, DOA, CRSCE 26

Space
 Space gives depth and
dimension and is in front of or
behind objects, around them, or
projecting from them.
 Space adds interest,
excitement, and contrast to a
visual design.
 Any shape that overlaps
another seems to be in front of
it and warm colors seem to be
in front of cool ones in the total
space of the composition.
 Anything which adds depth or
the appearance of depth will
enhance the display.

DIRECTION
 Compositions can have
direction - Horizontal,
Vertical or Oblique.
 Horizontal suggests
calmness, stability and
tranquility.
 Vertical gives a feeling of
balance, formality and
alertness.
 Oblique suggests
movement and action.
 The composition could be
centered and still too.

Directional Movement
 Directional Movement - is a
visual flow through the
composition.
 It can be the suggestion in a
visual design as the eye
moves from object to object
by way of placement and
position.
 Directional movement can be
created with the placement
and size of shapes used in a
composition.
 It is also with the placement
of dark and light areas that
attention can be moved
through a composition.

Note the different suggested directions in the four compositions

Texture
 Texture - is about surface quality either
tactile or visual. Texture can be real or
implied by different uses of media. It is
the degree of roughness or smoothness in
objects.
Texture is the surface quality of a shape -
rough, smooth, soft hard glossy etc.
Texture can be physical (tactile) or visual.

 Texture is a surface
quality.
 It relates to the
appearance of a surface.
 Appearance can be
perceived by either the
eyes or touch.
 Surfaces can look or feel
smooth, rough, soft, cool,
or warm.
 They can look pleasant or
unpleasant, which can
have a dramatic effect on
a display.

Texture
 Textures range from the smoothest polished
mirror to the roughest sandpaper like surface.
The term is often misused to refer only to rough
surfaces but this is not correct. All surfaces have
texture.
 A designer recognizes that different textures
can affect interest in different ways.
 Some surfaces are inviting and some are
repellent and reaction is normally created by
texture or color.
 Using different textures can increase interest in
a composition by adding variety without
changing color.

Texture
 Texture refers to the quality of a surface.
Everything that has a surface has texture.
There are two kinds of texture:
 Tactile touch 3D texture
 Visual illusion 2D texture

Texture
 TACTILE TEXTURE
Tactile means touch. Tactile texture is the
actual (3D) feel of a surface. This is of
paramount importance to three-
dimensional design but of can also be a
factor of generating interest in two-
dimensional design.
 The actual surface texture needs to either
be felt, or seen with light raking across its
surface to make the texture visible.

Texture
 VISUAL TEXTURE
Visual texture refers to the illusion of the
surface's texture.
 It is what a surface looks like.
 The textures seen in a photograph are
visual textures.
 No matter how rough objects in the
photograph look, the surface of the
photograph is smooth and flat.

 Visual texture is
always a factor in a
composition because
everything has a
surface and hence a
texture.
 Plain paper has a
boring texture that is
only slightly different
from the note book's
paper. Some other
colored papers are
more visually
interesting. This is
because of their color,
but also their texture.
 Look around to see
what interestingly
textures (both visual
and tactile) can be
seen.

PATTERN
 Patterns also create textures
 A recognizable motif regularly repeated produces a pattern.
Pattern requires repetition -- in design as in life (a pattern of
behavior). The more regular the repetition, the stronger the
pattern. Compare this field of flowers with a checkerboard. Both
have a repeating motif.
 All of the motifs in a pattern have surfaces, so there is always
texture. But there is not always pattern -- only when you notice it.

Texture and Pattern
 Texture and pattern are related. When you look closely at a
tree you can see the pattern of leaves that make its
surface. When you back away you loose awareness of the
leaves and notice the texture the leaves make on the tree.
Farther away still and you can see the pattern of the trees
making up the forest and finally the texture of the forest.
In this way pattern changes to texture as you loose sight
of the individual motifs. This is easy to do with natural
patterns, but you have to get quite far away from a
checker board grid to see it as texture.

 Patterns are generally more noticeable than
textures. This makes them a stronger visual
element for controlling attention.

 By now you would be reasonably well
acquainted with textures, space (2-D) and
direction in visual design.

Elements OF DESIGN
*Line
*Value
*Shape
*Form
*Color
*Texture
*Space
Henri Matisse. Interior with Egyptian Curtain 1948. Oil Painting

Line
When you, as a child, first picked up a crayon, a line
might have been the first mark you made. You use lines
to write numbers, symbols, and the letter of the alphabet.
You use lines to draw pictures. Lines are everywhere. In
drawing, line is an element of art that is the path of a
moving point through space.
What type of lines do
you see around you?

Artists use line to lead your eyes around a work of art. This is
because the artist wants to lead you through their composition. Line
creates movement, and leads your eye into, around, and out of visual
images as in this painting by Yvonne Jacquette. Oil, 1988
Notice how the artist uses the
line of the highway to pull
your eyes into the artwork.
Line has width as well as
length, but usually the width
of the line is smaller than the
length.
Artists create lines in many
different ways. A line can be
drawn on a paper with pencil
or scratched in clay with a
stick.

Some lines that we think we see in nature really do not
exist. For instance, when you look at the edges of shapes,
you think of lines. In the photo of the dogwood blossom,
notice that there are no black lines around the flower, only
black against white. However in a sketch of the same
blossom, lines are used to define the shape of the flower.

Kinds Of Line
Vertical
Horizontal
Diagonal
Curved
Zig Zag, or also known as geometric

Value
Value is the element of art
that describes the darkness
or lightness of an object.
Value depends on how much
light a surface reflects. A
surface has a dark value if it
reflects little light. It has a
light value if it reflects a lot of
light. Every time you make a
mark with a pencil, you are
creating a line with a certain
value. The harder you press,
the darker the value. A
series of closely placed lines
can create areas of dark
value. (Also known as
crosshatching)
Albrecht Durer. An Original Ruler Seated On a Throne. 1445. Pen and Ink

Value Bar. Various shades from white to black

Shapes and Form
All objects are either shapes or forms, whether they are
rocks, puddles, flowers, shirts, houses, whatever. The
words shapes and forms are used interchangeably in
everyday language, but in art, they mean very different
things.
A shape is a two dimensional area that is defined in some
way. In other words, it may have an outline or a boundary
around it. If you draw the outline of a square on a sheet of
paper, you have created a shape. All shapes can be
classified as geometric or free form shapes.
There are three basic geometric shapes that can be
defined with precise mathematical formulas.
square circle triangle

All other geometric shapes are variations or combinations of these
basic shapes
oval rectangle octagon parallelogram
hexagon
trapezoid pentagon
Free-form shapes are irregular and uneven shapes. Their
outlines may be curved, angular, or a combination of both.
Another term that is often used by your instructor is organic.
Organic is used when we talk about silhouettes of living things,
such as animals, trees, people, ect.

Forms
Forms are objects having three dimensions. Like shapes,
they both have length and width, but forms also have depth.
YOU are a three dimensional form, so is a tree or a table.

COLOR
Wassily Kandinsky Tension in Red 1926 oil
COLOR

Color
Color is the most expressive element of art. It shares a powerful
connection with emotion. Color can be a strong clue to an artists
symbolism, or meaning behind an artwork. Color can represent many
different feelings or ideas. Black can stand for mystery or evil, white
can mean purity or innocence. Red stands for love, passion, hunger, or
violence, green is meditative, calming, while blue is the symbol for
power, or royalty.
A prison system in North Carolina decided they would attempt to
reduce violent behavior within the prison by painting the prison with
the color pink. After consulting a color specialist, it was decided that
since pink is a feminine color, and females have less incidents of
violence, pink would be a good color for their facilities. After a few
months the rate of violence steadily increased. Prison officials were
left scratching their heads…what went wrong? Another color specialist
was consulted, and it was quickly discovered that pink is a variation of
red, which is the color of passion, and now the prison is a nice off
white.
Color is the element of art that is derived from reflective light. You
see color because light waves are reflected from objects to your eyes.

What color do you see
when you stare at the
red square, then shift
you gaze from the red
to the white area?
This is called an
afterimage. It occurs
because the receptors
in your eye retain the
visual stimulation
even after its has
ceased. Your brain
creates the afterimage
as a reaction to the
color you stared at
originally.

Hue
Hue is the name of a color in its true form. Red, blue, and yellow
are called primary colors. You cannot make primary hues by
mixing other hues together, however, by mixing black, white, or a
combination of primary colors, you can make any other color in the
spectrum.
Primary colors
Secondary colors are made by mixing two
primary colors.
Red and yellow Yellow and Blue Red and blue
orange Green Violet

Color Wheel
A color wheel is
the spectrum bent
into a circle. It is
a useful tool for
organizing colors.
There are yet
another group of
six colors called
intermediate, or
tertiary colors.
These are made
by mixing a
primary color with
a secondary colors
These colors include yellow green, yellow orange, red orange, blue
green, blue violet, red violet. Always list the primary color first
when referring to a tertiary color.

Color Schemes
Analogous Colors…colors that
are next to each other on the
color wheel, such as green and
yellow green.
Complementary
Colors…colors that are directly
across from each other such as
yellow and violet.
Monochromatic Colors…a
color scheme that uses only
one hue and black and white
mixed with that one color to
make tints, or values of that
color.
Warm colors
Cool colors

Your perception of color is influenced by the color that surrounds that
color. Notice that all squares are actually equal in size.

Franz Marc. Yellow Cow. 1911 oil.
Arbitrary Color. Artists sometimes use color to express emotions or
feelings, ignoring the actual colors of objects. They choose colors arbitrarily
to express meaning. Marc felt that yellow was a gentle, cheerful color which
symbolized the female, while blue symbolized the intellectual, and spiritual
male. Red symbolized the earth, with green being its compliment.

Texture
Jesus Bautista Moroles Granite Weaving Playscape 1995 granite
Everything you touch has its own
special feel, or texture. As an
element of art, texture may be
real, or implied or suggested, like
in a photograph, or in a painting.
Texture is the element of art that
refers to how things feel, or look
as if they might feel, if touched.
You perceive texture with two of
your senses; touch and vision.
Infants learn about their
environment by touching objects
and by putting them in their
mouths. Toddlers are attracted to
all objects that are within their
reach. When you look at surfaces,
you are able to guess their texture
because you have learned how
textures feel.

Janet Fish Oranges 1973 Pastel on Sandpaper
Janet Fish used pastels to create visual textures in this work.
In some areas she has combined different kinds of visual
textures, such as shiny-rough, and shiny smooth, and matte
smooth.

Space
Space refers to both outer space and inner space.
Rockets move through outer space to explore other
planets. People move through the inner space of
rooms and buildings. Space can be flat and two
dimensional, such as the space of a widow. Space
can also be three dimensional, such as the space
filled with water in a swimming pool.
Shapes and forms exist in space. Space is the
element of art that refers to the emptiness or area
between, around, above, below, or within objects.
All objects take up space. You for example, are a
living breathing form moving through space.
Shapes and forms are defined by the space around
and within them. They depend on space for their
existence. This is why it is important to understand
the relationship of space to shapes and form.

Positive and Negative Space
In both two and three dimensional art, the shapes or
forms are called the positive space or the figure. The
empty space between the forms are called negative space
or ground. In the next slide, Jasper Johns uses a play one
positive negative space. Are the faces or the vase the
positive or negative?

Jasper Johns Cups 4 Picasso 1972 Lithograph.
Do you see a vase or do you see profiles of Pablo Picasso. Jasper Johns
has deliberately organized this work as a visual puzzle to confuse the
viewer. One minute the faces are very clear and seem to be the figure,
while the space between the profiles is the ground. The next moment the
vase becomes figure and the space around the vase becomes the ground.

Experimenting with
Space
M.C. Escher Waterfall 1961 Lithograph
At first this print looks
normal. Water is falling to
turn a water wheel.
However, follow the water
from the base of the fall. It
runs uphill. Escher has
crated a visual puzzle using
the mathematics of
perspective.
