UNIVERSAL DESIGN
What is Universal Design
Universal Design is the design and composition of an environment so that it can be
accessed, understood and used to the greatest extent possible by all people regardless of
their age, size, ability or disability.
An environment (or any building, product, or service in that environment) should be
designed to meet the needs of all people who wish to use it. This is not a special
requirement, for the benefit of only a minority of the population. It is a fundamental
condition of good design.
If an environment is accessible, usable, convenient and a pleasure to use, everyone
benefits. By considering the diverse needs and abilities of all throughout the design
process, universal design creates products, services and environments that meet peoples'
needs. Simply put, universal design is good design.
PRICIPLES OF UNIVERSAL DESIGN:
Principle 1: Equitable Use
Principle 2: Flexibility in Use
Principle 3: Simple and Intuitive Use
Principle 4: Perceptible Information
Principle 5: Tolerance for Error
Principle 6: Low Physical Effort
Principle 7: Size and Space for Approach and Use
1. Equitable Use :- The design is useful and
marketable to people with diverse abilities.
Example :-
Power doors with sensors at entrances that are
convenient for all users
Integrated, dispersed, and adaptable seating in
assembly areas such as sports arenas and theaters
2. Flexibility in Use :- The design accommodates
a wide range of individual preferences and
abilities.
Example :-
Scissors designed for right- or left-handed
users
An automated teller machine (ATM) that has
visual, tactile, and audible feedback, a tapered
card opening, and a palm rest
3. Simple and Intuitive :- Use of the design is easy
to understand, regardless of the user's experience,
knowledge, language skills, or current
concentration level.
Example :-
An instruction manual with drawings and no
text
A moving sidewalk or escalator in a public
space
4.Perceptible Information :- The design
communicates necessary information effectively to
the user, regardless of ambient conditions or the
user's sensory abilities.
Example :-
Tactile, visual, and audible cues and instructions
on a thermostat
Redundant cueing (e.g., voice communications
and signage) in airports, train stations, and
subway cars
5.Tolerance for Error :- The design minimizes hazards
and the adverse consequences of accidental or
unintended actions.
Example :- An "undo" feature in computer software that
allows the user to correct mistakes without penalty
6.Low Physical Effort :- The design can be used
efficiently and comfortably and with a minimum of
fatigue.
Example :- Lever or loop handles on doors and
faucets
7.Size and Space for Approach and Use :- Appropriate
size and space is provided for approach, reach,
manipulation, and use regardless of user's body size,
posture, or mobility.
Example :-
Wide gates at subway stations that accommodate all
users
Controls on the front and clear floor space around
appliances, mailboxes, garbage dumpsters, and other
building elements
