• OS-Level Surface Haptics for Touch-Screen Accessibility

  Suhong Jin, Joe Mullenbach, Craig Shultz, J. Edward Colgate, Anne Marie Piper · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS)

  This demonstration paper introduces an operating system-level implementation of surface haptic feedback for Android tablets, built on the TPad Tablet platform developed at Northwestern University. The TPad combines a standard 7-inch Android tablet with a variable friction haptic…

• Enhancing Caption Accessibility through Simultaneous Multimodal Information: Visual-Tactile Captions

  Raja S. Kushalnagar, Gary W. Behm, Joseph S. Stanislow, Vasu Gupta · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS)

  This paper addresses a fundamental limitation of captions (subtitles) for deaf and hard of hearing (DHH) viewers: captions force viewers to split attention between reading text at the bottom of the screen and watching the visual action, inevitably causing them to miss…

• An Immersive Physical Therapy Game for Stroke Survivors

  Conor Kaminer, Kevin LeBras, Jordan McCall, Tan Phan, Paul Naud, Mircea Teodorescu, Sri Kurniawan · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS)

  This demo paper presents an immersive 3D game system designed to gamify physical therapy exercises for stroke survivors, enabling home-based rehabilitation that is both more engaging and capable of recording therapy progress. Stroke is identified as the number one cause of adult…

• Evaluation of Non-Visual Panning Operations Using Touch-Screen Devices

  HariPrasath Palani, Nicholas A. Giudice · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS 2014)

  This demonstration paper addresses a critical challenge in non-visual access to graphical information on touchscreens: how to pan across large-format graphics (maps, floor plans) without losing spatial orientation. The authors built on their Vibro-Audio Interface (VAI), which…
