• Application of Content Adaptation in Web Accessibility for the Blind

  Pauli P. Y. Lai · 2011 · Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper proposes transforming web pages into hierarchical, numbered menu structures — modeled on Interactive Voice Response Systems (IVRS) — so blind users can navigate content by pressing number keys rather than listening sequentially through entire pages. The author…

• Crosschecking the Mobile Web for People with Visual Impairments

  Luís Carriço, Rui Lopes, Rogério Bandeira · 2011 · Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper proposes a framework for evaluating mobile web accessibility for specific disability profiles by coherently merging three sets of guidelines: WCAG (web accessibility), W3C Mobile Web Best Practices (MWBP), and disability classifications from the ICF. The authors argue…

• Spindex (Speech Index) Improves Auditory Menu Acceptance and Navigation Performance

  Myounghoon Jeon, Bruce N. Walker · 2011 · ACM Transactions on Accessible Computing

  This paper introduces the "spindex" (speech index), a novel auditory cue designed to improve navigation through spoken menus on mobile devices. The spindex works by pronouncing the first letter of each menu item before the full text-to-speech (TTS) rendering—analogous to the…

• Supporting Blind Photography

  Chandrika Jayant, Hanjie Ji, Samuel White, Jeffrey P. Bigham · 2011 · ASSETS '11: The Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility

  This paper explores how blind and low-vision people use cameras and presents two applications designed to make photography more accessible. The research begins with a large-scale online survey of 118 blind and low-vision people that establishes the empirical foundation for the…

• Exploring Iconographic Interface in Emergency for Deaf

  Tânia Pereira, Benjamim Fonseca, Hugo Paredes, Miriam Cabo · 2011 · Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2011)

  This demonstration paper presents a mobile phone application that enables deaf people to communicate with emergency medical services using an iconographic touchscreen interface rather than voice calls. In Portugal at the time of publication, deaf people could only access…

• An Integrated System for Blind Day-to-Day Life Autonomy

  Hugo Fernandes, José Faria, Hugo Paredes, João Barroso · 2011 · Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2011)

  This demonstration paper presents nav4b, an integrated system designed to support the day-to-day autonomy of blind people by combining indoor/outdoor navigation guidance with object recognition in a single platform. Unlike existing solutions that require users to carry multiple…

• Evaluating Quality and Comprehension of Real-Time Sign Language Video on Mobile Phones

  Jessica J. Tran, Joy Kim, Jaehong Chon, Eve A. Riskin, Richard E. Ladner, Jacob O. Wobbrock · 2011 · Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2011)

  This paper investigates the relationship between objective video quality metrics (PSNR — peak signal-to-noise ratio), subjective quality preferences, and actual comprehension of American Sign Language (ASL) video transmitted at very low bitrates on mobile phones. At the time of…

• StopFinder: Improving the Experience of Blind Public Transit Riders with Crowdsourcing

  Sanjana Prasain · 2011 · The Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This doctoral consortium paper presents StopFinder, a mobile system that uses crowdsourcing to collect and provide information about non-visual landmarks around bus stops for blind public transit riders. The research addresses a fundamental challenge: while people who are blind…

• Analyzing Visual Questions from Visually Impaired Users

  Erin L. Brady · 2011 · The Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This doctoral consortium paper presents an analysis of the types of visual questions that visually impaired users ask through VizWiz, a mobile phone application that provides near-realtime answers to visual questions. VizWiz allows users to take a photo with their phone, speak a…

• TypeInBraille: A Braille-Based Typing Application for Touchscreen Devices

  Sergio Mascetti, Cristian Bernareggi, Matteo Belotti · 2011 · The Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This demonstration paper presents TypeInBraille, a novel text entry application for touchscreen smartphones that allows blind users to type using Braille code rather than the standard on-screen QWERTY keyboard. While screen readers like VoiceOver have made smartphones broadly…

• Situation-based Indoor Wayfinding System for the Visually Impaired

  Eunjeong Ko, Jin Sun Ju, Eun Yi Kim · 2011 · The Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper presents an indoor wayfinding system for visually impaired people that uses situation-aware color codes affixed to building walls to guide users to destinations in unfamiliar environments. The key innovation is a situation-based approach: rather than providing all…

• Blind People and Mobile Touch-based Text-Entry: Acknowledging the Need for Different Flavors

  João Oliveira, Tiago Guerreiro, Hugo Nicolau, Joaquim Jorge, Daniel Gonçalves · 2011 · The Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper investigates how individual differences among blind people affect their performance with different touchscreen text-entry methods. Thirteen blind participants (ages 24-62) were evaluated using four methods on a Samsung Galaxy S: QWERTY (standard VoiceOver-style…
