1 Scope
1.1 This Guide provides guidance to writers of relevant International Standards on how to take into account the needs of older persons and persons with disabilities. Whilst recognizing that some people with very extensive and complex disabilities may have requirements beyond the level addressed in this Guide, a very large number of people have minor impairments which can be easily addressed by relatively small changes of approach in standards, thereby increasing the market for the product or service.
This Guide aims
-
a) to inform, increase understanding and raise awareness about how human abilities impact on the usability of products, services and environments,
-
b) to outline the relationship between the requirements in standards and the accessibility and usability of products and services, and
-
c) to raise awareness about the benefits of adopting accessible design principles in terms of a wider market.
