• Site-Wide Annotation: Reconstructing Existing Pages to Be Accessible

  Hironobu Takagi, Chieko Asakawa, Kentarou Fukuda, Junji Maeda (2002) — Proceedings of the Fifth International ACM Conference on Assistive Technologies (Assets '02)

  This paper from IBM Tokyo Research Laboratory presents a system for making inaccessible web pages accessible through external annotations, without modifying the original pages. The core problem is "page fragmentation" — on visually designed web pages…

• Three web accessibility evaluation perspectives for RIA

  Nádia Fernandes, Ana Sofia Batista, Daniel Costa, Carlos Duarte, Luís Carriço (2013) — Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper presents a large-scale comparative study of web accessibility evaluation across three distinct perspectives that reflect how Rich Internet Applications (RIAs) are actually experienced by users. The three evaluation perspectives are: E1, ev…
