• Exploring feasibility of wrist gestures for non-visual interactions with wearables

  Shirin Feiz, I. V. Ramakrishnan · 2019 · Proceedings of the 16th International Web for All Conference (W4A)

  This paper investigates the accessibility of wrist gestures as an input modality for people with visual impairments (PVIs) interacting with smartwatches. Smartwatches hold particular promise for PVIs: they are always available, enable one-handed use (important when the other…

• Demonstration of GestureCalc: An Eyes-Free Calculator for Touch Screens

  Leah Perlmutter, Bindita Chaudhuri, Justin Petelka, Philip Garrison, James Fogarty, Jacob O. Wobbrock, Richard E. Ladner · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This demonstration paper presents GestureCalc, an eyes-free, target-less digital calculator for touch screen devices that replaces traditional button-based input with intuitive gesture-based input. The core problem is that existing calculator apps require precise tapping on…

• Typing Slowly but Screen-Free: Exploring Navigation over Entirely Auditory Keyboards

  Reeti Mathur, Aishwarya Sheth, Parimal Vyas, Davide Bolchini · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper introduces the concept of "keyflows" — entirely auditory keyboards that operate without a reference screen, enabling blind users to type while untethered from their mobile device. The core problem is that current accessible keyboards require blind users to constantly…

• GestureCalc: An Eyes-Free Calculator for Touch Screens

  Bindita Chaudhuri, Leah Perlmutter, Justin Petelka, Philip Garrison, James Fogarty, Jacob O. Wobbrock, Richard E. Ladner · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This full research paper presents GestureCalc, an eyes-free, target-less gesture-based calculator for touch screens, along with a rigorous three-session longitudinal evaluation with eight screen reader users. The system replaces the spatial button layout of conventional…

• Improving the Efficacy of Automated Sign Language Practice Tools

  Helene Brashear · 2007 · SIGACCESS Accessibility and Computing

  This paper describes dissertation research on improving automatic sign language recognition for CopyCat, an interactive computer game that helps young deaf children practice American Sign Language (ASL). The work addresses a critical need: 90% of deaf children are born to…
