User Interface Options Plus (UIO+) allows you to customize websites to match your own personal needs and preferences. Settings for the adaptations can be set via the UIO+ adjuster panel or, if on a GPII (Global Public Inclusive Infrastructure) enable machine, from a keyed in preference set.
Adaptive user interfaces can change their appearance and/or interaction behaviour to match the requirements of an individual user, the used device and current context conditions.
The Accessible Rich Internet Applications (WAI-ARIA) specification defines roles, states, and properties that should be used to provide semantics in languages where they may not be available. Assistive technologies, such as screen readers, use what ARIA offers in order to communicate with browsers to present information about the status of interactions, and the like. As a result, WAI-ARIA is especially important to consider when creating dynamic content.
