The Principles of Universal Design

The design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design. There are 4 main accessibility principles:

PERCEIVABLE

Starting at the most basic level, users must be able to process information. Take alternate means of processing into account. For example: providing text for those who cannot hear, and audio/alt text, etc. for those who cannot see.

OPERABLE

People need to be able to use a variety of tools to access content. All people, not just those with disabilities, make mistakes. Offer instructions to help all users.

UNDERSTANDABLE

If users can access your information, that doesn’t mean they can understand it. Understandable content uses clear, concise language and offers functionality that is easy to comprehend.

ROBUST

Users pick their own mix of technologies. Within limits, access to information should work well-enough across platforms, browsers, and devices to account for personal choice and user need.
