• Increasing the Accessibility of Pen-Based Technology: An Investigation of Age-Related Target Acquisition Difficulties

  Karyn Moffatt · 2007 · SIGACCESS Accessibility and Computing

  This paper describes dissertation research on improving the accessibility of pen-based devices (PDAs, Tablet PCs) for older adults by identifying and addressing the root causes of target acquisition difficulty. The author argues that previous research on target acquisition…

• Profiling Learners with Special Needs for Custom E-Learning Experiences, a Closed Case?

  Paola Salomoni, Silvia Mirri, Stefano Ferretti, Marco Roccetti · 2007 · Proceedings of the 2007 International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper from the University of Bologna tackles the problem of creating comprehensive learner profiles that capture both user accessibility needs and device capabilities — two dimensions that existing standards addressed separately but not together. The authors argue that no…

• Leveraging Rich Accessible Documents on the Web

  Rui Lopes, Luís Carriço · 2007 · Proceedings of the 2007 International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper by Lopes and Carriço from the University of Lisbon presents a framework for producing rich accessible documents on the web that goes beyond the common approach of providing simplified alternate versions for disabled users. The authors argue that accessibility in 2007…

• Humming Control Interface for Hand-held Devices

  Sook Young Won, Dong-In Lee, Julius Smith · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  This paper from Stanford University presents a control-by-humming interface that allows hands-free operation of portable devices such as cell phones and music players through subvocal humming detected by a Bluetooth-connected insertion earphone/microphone. The system converts…

• Using participatory activities with seniors to critique, build, and evaluate mobile phones

  Michael Massimi, Ronald M. Baecker, Michael Wu · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  This Assets '07 paper from University of Toronto engages older adults not as subjects of a usability study but as co-designers of a mobile phone system. Massimi, Baecker, and Wu argue that the two dominant trends in 'senior-friendly' phone design — oversimplified handsets like…

• Understanding mobile phone requirements for young adults with cognitive disabilities

  Melissa Dawe · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  Melissa Dawe's Assets '07 paper is a small, qualitative, ethnographically-informed study of how five Colorado families use mobile phones to support remote communication between parents and their young-adult children (ages 19-25) with cognitive disabilities. The paper is grounded…

• Semantic & syntactic context-aware text entry methods

  Jun Gong · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  Jun Gong's Assets '07 demonstration paper proposes a context-aware extension to the dictionary-based predictive disambiguation (DBPD) text-entry methods — the family that included the once-ubiquitous T9 on mobile phone keypads. DBPD methods let users press each multi-letter key…

• Barrier pointing: using physical edges to assist target acquisition on mobile device touch screens

  Jon Froehlich, Jacob O. Wobbrock, Shaun K. Kane · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  Froehlich, Wobbrock and Kane propose barrier pointing: a set of stylus-based target acquisition techniques that exploit the raised physical edge of a mobile touch screen to stabilise input for users with motor impairments. Standard touch-screen tapping requires a user to fly the…
