Website operators can promote
Universal Usability by giving information to users about the measures
taken at their site. A Universal Usability statement based on a standard
template would provide users with an easy-to-read, one-page summary of
the requirements and accommodations made at a given site.
The checklist given below provides several categories and subcategories
of measures that might be used to describe the Universal Usability efforts
of a given site. Each subcategory describes the kind of information that
should be provided (yes/no, lists, version numbers, etc.). Many sites
will find that many of these categories do not apply. However, for those
entries that do apply, site operators can increase the usability of their
site by providing as much detail as possible.
