  • 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…

  • Slipping and drifting: using older users to uncover pen-based target acquisition difficulties

    Karyn A. Moffatt, Joanna McGrenere · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '07)

    Moffatt and McGrenere present an empirical study at the University of British Columbia investigating the underlying causes of pen-based target acquisition difficulty on a Tablet PC, with explicit attention to how age affects targeting ability. Thirty-six right-handed…

  • A comparison of area pointing and goal crossing for people with and without motor impairments

    Jacob O. Wobbrock, Krzysztof Z. Gajos · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '07)

    Wobbrock and Gajos at the University of Washington present a controlled study comparing two fundamentally different target-acquisition paradigms — conventional area pointing (move into a confined region and click) and goal crossing (sweep the cursor across a goal line, no click…

  • 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…
