• ThermalCane: Exploring Thermotactile Directional Cues on Cane-Grip for Non-Visual Navigation

  Arshad Nasser, Kai-Ning Keng, Kening Zhu (2020) — Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This paper presents ThermalCane, a white-cane grip augmented with flexible Peltier thermoelectric modules that provide thermal directional cues for blind and visually impaired (BVI) navigation. While existing haptic navigation aids primarily use vibr…

• Making Mobile Augmented Reality Applications Accessible

  Jaylin Herskovitz, Jason Wu, Samuel White, Amy Pavel, Gabriel Reyes, Anhong Guo, Jeffrey P. Bigham (2020) — Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This paper tackles a fundamental accessibility gap in augmented reality: AR applications are overwhelmingly visual, mixing virtual 3D objects with the real world in ways that existing screen readers and accessibility services cannot interpret. The re…

• Challenging and Improving Current Evaluation Methods for Colour Identification Aids

  Connor Geddes, David R. Flatla (2022) — Proceedings of the 24th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 22)

  This paper critically examines how Colour Vision Deficiency (CVD) aids are evaluated, exposing fundamental flaws in common evaluation practices. CVD affects approximately 5% of the population and impairs the ability to accurately identify and discrim…

• 30 Years of Solving the Wrong Problem: How Recolouring Tool Design Fails those with Colour Vision Deficiency

  Connor Geddes, David R. Flatla, Ciabhan L. Connelly (2023) — Proceedings of the 25th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '23)

  This paper critically examines three decades of research into recolouring tools — colour filters and daltonization algorithms designed to help people with Colour Vision Deficiency (CVD) differentiate colours — and finds that these tools fundamentally…
