2.  Universal usability is the design of things such
that they are useful to as many people as
possible. For example , a sidewalk may be
designed for people with disabilities, baby
carriages, bicyclist, commercial deliveries and
to protect pedestrians from cars. Universal
design is a move away from design for the “
average” person by considering a wide variety
of diverse use cases.
