• Real-Time Depth-Camera Based Hand Tracking for ASL Recognition

  Brandon Taylor, Anind Dey, Daniel Siewiorek, Asim Smailagic (2017) — Proceedings of the 19th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This demonstration paper validates the use of a publicly available real-time hand tracking algorithm (Sphere-Mesh) for recognizing American Sign Language (ASL) handshapes using a depth camera. Sign Language Recognition (SLR) has long been a motivatin…

• TouchPilot: Designing a Guidance System that Assists Blind People in Learning Complex 3D Structures

  Xiyue Wang, Seita Kayukawa, Hironobu Takagi, Chieko Asakawa (2023) — Proceedings of the 25th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2023)

  This paper introduces TouchPilot, a step-by-step guidance system designed to help blind people independently learn complex 3D structures through interactive 3D printed models (I3Ms). While existing I3Ms allow blind users to trigger audio labels by po…

• How Accessible are Virtual Reality Freehand Gestures? Understanding Barriers for Users with Upper Limb Motor Impairments

  Lauren Pococke, Crescent Jicol, Christof Lutteroth, Christopher Clarke (2025) — ASSETS 2025: 27th International ACM SIGACCESS Conference on Computers and Accessibility

  This paper provides the first empirical examination of how accessible default freehand gesture implementations in virtual reality are for people with upper limb motor impairments. The researchers recruited 8 adults with conditions including lupus, rh…
