• 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…

• HapticRiaMaps: Towards Interactive Exploration of Web World Maps for the Visually Impaired

  Nikolaos Kaklanis, Konstantinos Votis, Panagiotis Moschonas, Dimitrios Tzovaras · 2011 · Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper presents HapticRiaMaps, a free open-source web application from the Centre for Research and Technology-Hellas (CERTH) in Greece that makes online 2D maps accessible to visually impaired users through haptic force feedback and audio sonification. The system retrieves…

• 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…

• 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…

• Providing Haptic Feedback Using the Kinect

  Brandon T. Shrewsbury · 2011 · The Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This poster paper presents a system that combines the Microsoft Kinect depth camera with a custom haptic glove to provide spatial awareness to people who are blind or visually impaired. The research addresses a gap in existing mobility aids: while canes detect obstacles within a…

• 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…

• Supporting Spatial Awareness and Independent Wayfinding for Pedestrians with Visual Impairments

  Rayoung Yang, Sangmi Park, Sonali R. Mishra, Zhenan Hong, Clint Newsom, Hyeon Joo, Erik Hofer, Mark W. Newman · 2011 · The Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper presents Talking Points 3 (TP3), a location- and orientation-aware smartphone system designed to increase the "legibility" of indoor environments for pedestrians with visual impairments, fostering spatial awareness rather than simply providing turn-by-turn directions.…

• On the Audio Representation of Radial Direction

  Susumu Harada, Hironobu Takagi, Chieko Asakawa · 2011 · Proceedings of the SIGCHI Conference on Human Factors in Computing Systems (CHI '11)

  This paper proposes a new primitive for auditory displays — radial direction — and evaluates a concrete mapping of vowel-like sounds to eight cardinal and ordinal directions. The authors observe that almost all prior sonification work has mapped data to linear sound properties…
