Accessibility

The "ability to access" the functionality of a system or entity, and gain the related benefits. The degree to which a product, service, or environment is accessible by as many people as possible. Accessible design ensures both direct (unassisted) access and indirect access through assistive technology (e.g., computer screen readers). In this sense, thinking about digital accessibility makes us consider the way in which we share information. Universal design ensures that an environment can be accessed, understood, and used to the greatest extent possible by all people.
