This Guideline provides core principles, guiding concepts, and tools applicable to the design and provision of PSE that are for use by seniors and those whose abilities are affected by aging. The Guideline may also be applied to designing PSE for the population at large, in conformance with the objectives of universal design.
The objective of this Guideline is to assist individuals and organizations in
(a) raising the awareness of how variations in human abilities affect the usability and safety of PSE;
(b) developing and implementing the practices of design for aging (DFA); and
(c) providing PSE that improve utility and accessibility, reduce health and safety risks, enhance quality of life, maintain dignity, and promote inclusion.
This Guideline may not apply to PSE for
(a) seniors with very severe or complex disabilities; or
(b) those whose disabilities or functional limitations are not the result of aging.
This Guideline does not reduce or replace regulations or other requirements for safety and functional provision of PSE.
1.4 Language of the Guideline
The use of this Guideline is voluntary. Because the principles, concepts, keywords, and design solutions are all written in general terms, not detailed as specific requirements, the word #should# has been used throughout. If an organization chooses to adopt the Guideline, it should review how to structure and define the prescriptive requirements.
