computer accessibility

Computer accessibility refers to the accessibility of a computer system to all people, regardless of disability type, English literacy or digital fluency. The term accessibility is most often used in reference to specialized hardware or software, or a combination of both, designed to enable the use of a computer by a person with a disability or impairment. Accessibility is often abbreviated as the numeronym a11y, where the number 11 refers to the number of letters omitted. This parallels the abbreviations of internationalization and localization as i18n and l10n, respectively. Moreover, a11y is also listed on the USPTO Supplemental Register under Accessibility Now, Inc.

Compiled from independent standards experts, this document is the most comprehensive and technical standard for designing accessible features for software, covering all disabilities and all aspects of software. It provides examples of two priority levels ('Required' and 'Recommended') and offers a handy checklist designed to help with recording software testing results. Because of its complexity and technical nature, and with upwards of 150 individual statements, ISO 9241-172 is difficult to interpret and apply. Luckily, not every statement is relevant to every situation, so it may be advisable to identify a subset of statements that are tailored to the particular software environment, making the use of this document much more achievable.
