Mixed-Initiative Design

An interaction design approach in which both the system and the user can take initiative in directing the flow of interaction, rather than one party being entirely in control. In accessibility contexts, mixed-initiative design is used to balance automated system actions (such as notifying users of dynamic content updates) with user autonomy (allowing them to decide when and whether to engage with those updates). This approach is particularly important for assistive technology users, where interruptions can be disorienting — for example, a screen reader using mixed-initiative design might play a subtle earcon to signal a page update, then let the user choose when to review the change rather than immediately redirecting focus.
