As we interact with user agents on a variety of devices, a growing number of asynchronous events, such as alerts and notifications, can arise that seek to capture the user's attention. These events arise from a hierarchy of sources, with varying urgency and relevance to the user. For users of assistive technologies, notifications can be disruptive to ongoing tasks, and techniques, such as ARIA live regions have been developed as a means to define when screen updates should be announced. Can the ARIA model serve as a more general model for defining how alerts and notifications should be handled in user agents? Further, should alert and notifications be re-thought to enhance accessibility, and specifically, to ensure that alerts can be detected and understood by all?
