Information Hierarchy

The organization and prioritization of information elements in an interface, determining what users encounter first and how content is structured for navigation. In accessibility, information hierarchy is crucial because screen reader users experience content sequentially rather than scanning visually. For calendar applications, BLV users prefer event titles before times (contrary to standard chronological time-first ordering), and list-based displays over grid layouts. Accessible information hierarchy should align with user task priorities rather than visual design conventions, use proper heading structures for screen reader navigation, and present the most important information first to minimize the time spent searching for relevant content.
