• Exploring Visual and Motor Accessibility in Navigating a Virtual World

  Shari Trewin, Mark Laff, Vicki Hanson, Anna Cavender · 2009 · ACM Transactions on Accessible Computing

  This paper explores accessibility requirements for 3D virtual worlds, using PowerUp—an educational multiplayer game teaching middle schoolers about renewable energy—as a testbed. Virtual worlds present unique accessibility challenges: they rely on visual realism and dynamic…

• Haptic Handheld Wayfinder with Pseudo-Attraction Force for Pedestrians with Visual Impairments

  Tomohiro Amemiya, Hisashi Sugiyama · 2009 · Proceedings of the 11th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '09)

  This paper presents a compact handheld haptic device that guides visually impaired pedestrians by generating a directional force sensation — a feeling of being pulled or pushed toward the correct direction. The device exploits a perceptual phenomenon called "pseudo-attraction…

• Instant Tactile-Audio Map: Enabling Access to Digital Maps for People with Visual Impairment

  Zheshen Wang, Baoxin Li, Terri Hedgpeth, Teresa Haven · 2009 · Proceedings of the 11th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '09)

  This paper presents an automated system for converting standard digital map images into interactive tactile-audio maps that people who are blind can explore independently. The core problem addressed is that while online map services like Google Maps provide rich geographical…

• Real-Time Anomaly Detection for Traveling Individuals

  Tian-Shya Ma · 2009 · Proceedings of the 11th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '09)

  This short paper presents a real-time anomaly detection system designed to help individuals with cognitive impairments travel safely and independently on routine journeys such as commuting via public transportation. The system works by comparing a traveller's current GPS…

• Usability of a multimodal videogame to improve navigation skills for blind children

  Jaime Sánchez, Mauricio Sáenz, Miguel Ripoll · 2009 · Proceedings of the 11th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '09)

  This paper presents a usability evaluation of two complementary tools designed to help blind school-aged children develop orientation and mobility (O&M) skills in closed, unfamiliar spaces. The first tool is the Digital Clock Carpet (DCC), a custom-built haptic input device…
