The
world is full of diverse people, so the technology should be rich enough to
deal with all kind of people. So, the concept of universal design came into
being. As the name depicts universal design is design for all people,
regardless of their age, sex, education level, language, and impairments. The
concept of Universal design was introduced by North Carolina University in the
1990s (Connell et al., 1997) when the researchers of the University proposed to
make such a flexible design that can be used by all the people of the world
including the disabled one. Universal design has seven principles:
1.
Equitable use
2. Flexibility
in use
3.
Simple and intuitive use
4.
Perceptible information
5.
Tolerance for Error
6.
Low physical effort
7.
Size and space for Approach and use (Connell et al., 1997)
We should follow
these principles to make a universally designed system. Universal design is now
being used in different systems e.g. athletes are using Universal design for
learning in the most effective way (Vargas, Beyer and Flores). Universal design
plays a very vital role for diverse learners. Universal design for the learner
is a framework that provides guidelines. These guidelines help to make
documents accessible for all readers regardless of their diversity and
impairments (Scanlon,
Schreffler and James).
Similarly, universal design can also be used in the emergency management
system.
