Universal design is an approach to design that honours human diversity. It addresses the right for everyone – from childhood into their oldest years – to use all spaces, products and information, in an independent, inclusive and equal way. It is a process that invites designers to go beyond compliance with access codes, to create excellent, people centred design.
(Elaine Ostroff)
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 or disability
(Disability Act, 2005)
The design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialised design
(Centre for Universal Design, North Carolina State University)

6. Low Physical Effort
