• Corridor-Walker: Mobile Indoor Walking Assistance for Blind People to Avoid Obstacles and Recognize Intersections

  Masaki Kuribayashi, Seita Kayukawa, Jayakorn Vongkulbhisal, Chieko Asakawa, Daisuke Sato, Hironobu Takagi, Shigeo Morishima · 2022 · Proceedings of the ACM on Human-Computer Interaction (Proc. ACM Hum.-Comput. Interact., Vol. 6, MHCI, Article 179)

  Walking an indoor corridor independently is deceptively hard for a blind traveller. Two problems compound: avoiding obstacles stacked against the wall (the same wall the traveller uses as a tactile guide) and recognising when an intersection has arrived and which directions it…

• LineChaser: A Smartphone-Based Navigation System for Blind People to Stand in Lines

  Masaki Kuribayashi, Seita Kayukawa, Hironobu Takagi, Chieko Asakawa, Shigeo Morishima · 2021 · Proceedings of the 2021 CHI Conference on Human Factors in Computing Systems

  Standing in line is a mundane-looking task — at a cashier, bus stop, or airport check-in — but for a blind person it is a brittle, anxiety-ridden sequence: find where the line currently ends (a position that moves), join it without bumping into anyone, and then shuffle forward…

• Smartphone-Based Assistance for Blind People to Stand in Lines

  Seita Kayukawa, Hironobu Takagi, João Guerreiro, Shigeo Morishima, Chieko Asakawa · 2020 · Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems (CHI EA '20, Late-Breaking Work)

  This CHI 2020 Late-Breaking Work is the preliminary study that seeded the CHI 2021 LineChaser paper by the same research group. Where the fuller LineChaser system would later combine line-end finding with AR-marker-based localisation and a dual audio/vibration interface, this…

• Exploring Aural and Haptic Feedback for Visually Impaired People on a Track: A Wizard of Oz Study

  Kyle Rector, Rachel Bartlett, Sean Mullan · 2018 · Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2018)

  This University of Iowa study investigates how to make outdoor jogging tracks accessible to people who are blind or have low vision, addressing a gap in exercise accessibility research. Standard 400-meter tracks rely entirely on visual lane markings, and the overwhelming…
