• A Macroscopic Web Accessibility Evaluation at Different Processing Phases

  Nádia Fernandes, Luís Carriço (2012) — Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper investigates a fundamental question about automated accessibility evaluation: does it matter whether you evaluate a web page as it arrives from the server (before browser processing) or as the user actually experiences it (after browser pr…
