• Proposing New Metrics to Evaluate Web Usability for the Blind

  Kentarou Fukuda, Shin Saito, Hironobu Takagi, Chieko Asakawa (2005) — CHI '05 Extended Abstracts on Human Factors in Computing Systems

  This four-page CHI '05 extended abstract argues that existing automated accessibility checkers — in 2005 typified by Bobby — had plateaued: they verified the presence of ALT attributes, labels, and markup conformance, yet real blind users still found…

• User Interface of a Nonvisual Table Navigation Method

  Chieko Asakawa, Takashi Itoh (1999) — CHI '99 Extended Abstracts on Human Factors in Computing Systems

  This two-page CHI '99 late-breaking-results extended abstract addresses a problem that was central to the early accessible web: HTML tables were everywhere — used both for tabular data and, at the time, as a layout device — but talking web browsers r…

• Analysis of Navigability of Web Applications for Improving Blind Usability

  Hironobu Takagi, Shin Saito, Kentarou Fukuda, Chieko Asakawa (2007) — ACM Transactions on Computer-Human Interaction (TOCHI), Vol. 14, No. 3, Article 13

  This TOCHI article is a two-study investigation into why modern web applications — especially visually dense online shopping sites — remain slow and frustrating for blind users even when they pass automated accessibility checks. The authors argue tha…

• Accessibility Commons: A Metadata Repository for Web Accessibility

  Shinya Kawanaka, Masatomo Kobayashi, Hironobu Takagi, Chieko Asakawa (2009) — ACM SIGWEB Newsletter, Summer 2009

  This short SIGWEB Newsletter article proposes Accessibility Commons (AC), a shared federated repository for externally authored web-accessibility metadata. The authors argue that accessibility cannot scale as long as fixes depend on the original site…

• Sasayaki: Augmented Voice Web Browsing Experience

  Daisuke Sato, Shaojian Zhu, Masatomo Kobayashi, Hironobu Takagi, Chieko Asakawa (2011) — Proceedings of the SIGCHI Conference on Human Factors in Computing Systems (CHI '11)

  This paper introduces Sasayaki (Japanese for 'whisper'), a prototype that augments the standard screen-reader voice with a second, physically separated synthesised voice that whispers contextually relevant hints — for example 'entering main content',…

• A Semantic-Web Based Framework for Developing Applications to Improve Accessibility in the WWW

  Christos Kouroupetroglou, Michail Salampasis, Athanasios Manitsaris (2006) — Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper presents a Semantic Web application framework designed to improve web accessibility by adding a metadata annotation layer on top of existing web pages. The framework addresses a core problem for blind users: screen readers serialize web pa…
