• Understanding the Role of Age and Fluid Intelligence in Information Search

  Shari Trewin, John T. Richards, Vicki L. Hanson, David Sloan, Bonnie E. John, Cal Swart, John C. Thomas · 2012 · Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This study investigates whether age or fluid intelligence is the more important factor driving differences in how people search for information in hierarchical web interfaces. The researchers recruited three groups: 14 younger adults with high fluid intelligence (YH, mean age…

• Detecting Linguistic HCI Markers in an Online Aphasia Support Group

  Yoram M. Kalman, Kathleen Geraghty, Cynthia K. Thompson, Darren Gergle · 2012 · Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This paper investigates whether the language deficits associated with aphasia — an acquired language disorder typically resulting from stroke or brain injury — can be detected in online written communication. The concept of "HCI markers" is introduced: measurable signals…

• Exploration and Avoidance of Surrounding Obstacles for the Visually Impaired

  Limin Zeng, Denise Prescher, Gerhard Weber · 2012 · Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This paper presents the 3DOD (3D Obstacle Detector), a wearable system that combines a 3D Time-of-Flight (TOF) camera with a portable multi-line refreshable Braille display to help blind pedestrians detect and avoid obstacles beyond the reach of a white cane. White canes detect…

• Online Quality Control for Real-Time Crowd Captioning

  Walter S. Lasecki, Jeffrey P. Bigham · 2012 · Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This paper addresses quality control in Legion:Scribe, a system that provides real-time captioning by having multiple non-expert crowd workers simultaneously type what they hear, then automatically merging their partial transcriptions into a single caption stream. Real-time…

• Considerations for Technology that Support Physical Activity by Older Adults

  Chloe Fan, Jodi Forlizzi, Anind Dey · 2012 · Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This paper investigates how technology can help older adults overcome barriers to physical activity through a needs-based, qualitative research approach. Rather than starting from technology capabilities, the researchers interviewed 12 physically active older adults (aged 61-90)…

• Liberi and the Racer Bike: Exergaming Technology for Children with Cerebral Palsy

  Zi Ye, Hamilton A. Hernandez, T.C. Nicholas Graham, Darcy Fehlings, Lauren Switzer, Md Ameer Hamza, Irina Schumann · 2012 · Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This demonstration paper presents Liberi, a multiplayer exercise video game, and a custom cycling-based exergaming station designed to enable children with cerebral palsy (CP) to engage in vigorous physical exercise while playing with peers. Children with CP face limited…

• Tapulator: A Non-Visual Calculator Using Natural Prefix-Free Codes

  Vaspol Ruamviboonsuk, Shiri Azenkot, Richard E. Ladner · 2012 · Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This demonstration paper presents the Tapulator, a non-visual calculator for smartphones that replaces traditional on-screen buttons with a simple gesture-based numeric entry system using multi-finger taps and swipes. The core innovation is a natural prefix-free code for…

• Transforming Japanese Archives into Accessible Digital Books

  Tatsuya Ishihara, Toshinari Itoko, Daisuke Sato, Asaf Tzadok, Hironobu Takagi · 2012 · JCDL '12: Proceedings of the 12th ACM/IEEE-CS Joint Conference on Digital Libraries

  This JCDL 2012 paper from IBM Research Tokyo and Haifa tackles a problem that remained invisible in most English-focused digitisation work: producing fully accessible digital books from Japanese archives, where the writing system uses more than 10,000 characters (kanji plus…
