Presentation Description/Abstract
As mobile-first interfaces increasingly shape how users search, navigate, and interpret digital information, understanding their accessibility and Human Factors implications is essential.
Siu and Chaparro (2014) demonstrated that grid-based and list-based search interfaces produce distinct visual scanning patterns and perceptions of information hierarchy. Contemporary mobile interfaces, including vertically navigated platforms such as TikTok, introduce additional perceptual, cognitive, and interaction demands.
This integrative literature review examines grid-based and sequential mobile interface layouts using human factors principles and the Web Content Accessibility Guidelines (WCAG) 2.2. The analysis evaluates how interface organization relates to visual scanning, navigation performance, cognitive workload, and accessibility for users with varied perceptual and functional capabilities.
Particular attention is given to the distinction between accessibility conformance and measurable usability outcomes. The review synthesizes existing evidence to identify interface characteristics that support or constrain accessible interaction across different tasks and user populations. Findings will inform evidence-based UX/UI design education and establish testable hypotheses for future comparative eye-tracking studies extending Siu and Chaparro's (2014) research to contemporary mobile interfaces.
