UNIVERSAL DESIGN PRINCIPLES
By the Center for Universal Design (CUD) at North Carolina State
University, established 7 principles of UD to provide guidance in the design of products and environments. Following are the CUD
principles of UD, each followed with an example of its application:
- Equitable
use.
The design is useful and marketable to people with diverse abilities. For
example, a website that is designed to be accessible to everyone, including
people who are blind, employs this principle.
- Flexibility
in Use.
The design accommodates a wide range of individual preferences and
abilities. An example is a museum that allows visitors to choose to read
or listen to the description of the contents of a display case.
- Simple
and intuitive.
Use of the design is easy to understand, regardless of the user's
experience, knowledge, language skills, or current concentration level.
Science lab equipment with clear and intuitive control buttons is an
example of an application of this principle.
- Perceptible
information.
The design communicates necessary information effectively to the user,
regardless of ambient conditions or the user's sensory abilities. An
example of this principle is captioned television programming projected in
noisy restaurants.
- Tolerance
for error.
The design minimizes hazards and the adverse consequences of accidental or
unintended actions. An example of a product applying this principle is
software applications that provide guidance when the user makes an
inappropriate selection.
- Low
physical effort.
The design can be used efficiently, comfortably, and with a minimum of
fatigue. Doors that open automatically for people with a wide variety of
physical characteristics demonstrate the application of this principle.
- Size
and space for approach and use.
Appropriate size and space is provided for approach, reach, manipulation,
and use regardless of the user's body size, posture, or mobility. A
flexible work area designed for use by employees with a variety of
physical characteristics and abilities is an example of applying this
principle.
