Design Theory - ✔✔A way to direct design based on a system of beliefs or philosophy.
Theory - ✔✔The most fundamental beginning of design.
Design History - ✔✔A valuable contribution to design theory by suggesting how past designs solved
certain problems or represented particular ideal.
Environmental Design - ✔✔A theory that focuses on the interaction between humans and their
environments that attempts to develop a rational design approach based on scientific research rather
than anecdotal evidence or personal philosophy. Often does not take into account the interaction
between humans and buildings.
Evidence Based Design - ✔✔Basing design in credible research that links one or more environmental
elements with a desired outcome. Often used in healthcare but has been applied to education and
workplace design.
Functionalism - ✔✔A simple rational design solution to design problems without extraneous decoration.
Reduced interiors to only what was required to meet strict functional needs without unnecessary
decorations.
Le Corbusier - ✔✔A house is a machine for the living
Gestalt Pyschology - ✔✔a psychological approach that emphasizes that we often perceive the whole
rather than the sum of the parts
Simultaneous Constrast - ✔✔a phenomenon in which a color appears to change depending on the
background color.
,Grouping - ✔✔humans perceive separate units in the visual field as a group, through proximity,
similarity, direction, and context
Closure (form constancy) - ✔✔the tendency to perceive incomplete forms as a whole
Continuity - ✔✔the tendency to see a line or shape as continuing in a particular direction rather than
making a sharp turn.
Simplicity - ✔✔humans prefer the simplest, most stable organization of forms. the brain organizes forms
into the fewest number of lines or parts.
Figure-ground - ✔✔the was form (figure) is distinguished from surroundings (ground)
Perceptual Constancy - ✔✔perceiving objects as unchanging (having consistent lightness, color, shape,
and size) even as illumination and retinal images change
Shape Constancy - ✔✔the perception of objects as having their original shape regardless of change in
orientation or point of view.
Size Constancy - ✔✔the perception of objects having the same size regardless of viewing distance.
Lightness Constancy - ✔✔the perception of objects to have the same lightness or darkness regardless of
the illumination of the space in which it is viewed
Color Constancy - ✔✔the perception of an objects color as the same regardless of the lighting conditions
Binocular Disparity - ✔✔the difference in the retinal images of the left and right eye which allows the
viewer to perceive distance and three-dimensions
Interposition - ✔✔a distant object may appear to be overlapped or partly hidden by a closer object
,Linear Perspective - ✔✔parallel lines appear to recede toward a single point in the distance
Atmosphere Perspective - ✔✔haziness of an object that increases with distance caused by small
particles in the air
Texture Perspective - ✔✔the density of a texture seems to increases as the distance for the viewer
increases.
Size Clues - ✔✔when wo objects are the same size but the further one will make a smaller image on the
retina than the closer
Horizon Line Relationship - ✔✔the closer an object is to the horizon line the further away it is.
Cue Inconsistency - ✔✔visual cue inconsistencies such as an unpleasant smell in a restaurant or echoes
in a small intimate space
Political conditions - ✔✔A social and cultural belief that influence interior design through political
thought that creates awareness to a design ideal
Economic Conditions - ✔✔A social and cultural belief that influence interior design through the
economic growth at the time.
cultural attitudes - ✔✔A social and cultural belief that influence interior design through cultural views of
family, shared values, religion, fashion, leisure pursuits, sports, etc.
Symbolism - ✔✔A social and cultural belief that influence interior design though a clients idea of what
the project should be.
Regionalism - ✔✔A social and cultural belief that influence interior design by local geographic area
, Maslow's Hierarchy of Needs - ✔✔A variety of human needs that are defined by two groups: deficiency
needs and growth needs. Deficiency needs are food, water, minimal bodily comforts, safety needs,
belonging and love, self- esteem. Growth needs are self-actualization, education, order and beauty, and
self transcendence.
Behavior Setting - ✔✔A particular place with definable boundaries and objects in which a standing
pattern of behavior occurs at a particular time.
Territoriality - ✔✔The human need to lay claim to the spaces we occupy and the things we own.
Proxemics - ✔✔Created by Edward T. Hall which describes how people use space.
Intimate Distance - ✔✔Physical contact to 18"
Personal Distance - ✔✔18" to 4'
Social Distance - ✔✔4 to 12 feet. 4 to 7 in a close phase and 7 to 12 in the far phase.
Public Distance - ✔✔Ranging from 12 feet outward
Point - ✔✔perceived when a two dimensionally perceived object appears relatively small in relation to
the plane against which it is seen
Line - ✔✔an object or form whose actual or visual length greatly exceeds any actual width or depth it
may have
Plane - ✔✔a form with two dominant dimensions, length and width
Volume - ✔✔true three dimensional aspect of interior design having length, width, and depth. solid
(with mass) or void (space itself, defined by planes or other elements) or positive and negative space
