• Haptic comparison of size (relative magnitude) in blind and sighted people

  Sarah A. Douglas, Shasta Willson (2007) — Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  Douglas and Willson's Assets '07 paper is a controlled psychophysical study of how blind and sighted users compare relative magnitude using a PHANToM force-feedback device — the workhorse haptic input-output device of the era. The motivating problem …

• Accessible Touchscreen Technology for People with Visual Impairments: A Survey

  William Grussenmeyer, Eelke Folmer (2017) — ACM Transactions on Accessible Computing

  This comprehensive survey reviews the state of the art in touchscreen accessibility for people who are blind or have low vision, covering research from the mid-1990s through 2016. The authors organize the field by input modalities (gestural, voice, s…

• Refreshable Braille Oral Appliance

  M. A. Naomi Jobrack (2015) — Proceedings of the 12th International Web for All Conference (W4A)

  This paper presents preliminary research toward developing a Refreshable Braille Oral Appliance (RBOA) — a refreshable Braille display embedded in an oral retainer that would allow users to read Braille with their tongue. The envisioned device connec…

• SoundHapticVR: Head-Based Spatial Haptic Feedback for Accessible Sounds in Virtual Reality for Deaf and Hard of Hearing Users

  Pratheep Kumar Chelladurai, Ziming Li, Maximilian Weber, Tae Oh, Roshan L Peiris (2024) — ASSETS '24: Proceedings of the 26th International ACM SIGACCESS Conference on Computers and Accessibility

  This paper presents SoundHapticVR, a head-based haptic feedback system that converts spatial audio cues in virtual reality into vibrotactile feedback for Deaf and Hard of Hearing (DHH) users. VR environments rely heavily on spatial audio to convey cr…
