  • Subdivision surface fitting to a dense mesh using ridges and umbilics 

    Ma, Xinhui; Keates, Simeon; Jiang, Yong; Kosinka, Jiri (Elsevier, 2014-11-20)
    Fitting a sparse surface to approximate vast dense data is of interest for many applications: reverse engineering, recognition and compression, etc. The present work provides an approach to fit a Loop subdivision surface ...
  • A submovement analysis of cursor trajectories 

    Hwang, F.; Keates, Simeon; Langdon, P.; Clarkson, J. (Taylor & Francis, 2005)
    Understanding human movement is key to improving input devices and interaction techniques. This paper presents a study of mouse movements of motion-impaired users, with an aim to gaining a better understanding of impaired ...
  • The use of cursor measures for motion-impaired computer users 

    Keates, Simeon; Hwang, F.; Langdon, P.; Clarkson, P. J.; Robinson, P. (Springer Verlag, 2002-11)
    “Point and click” interactions remain one of the key features of graphical user interfaces (GUIs). People with motion-impairments, however, can often have difficulty with accurate control of standard pointing devices. This ...
  • User models and user physical capability 

    Keates, Simeon; Langdon, Patrick; Clarkson, P. John; Robinson, Peter (Springer Verlag, 2002-06)
    Current interface design practices are based on user models and descriptions derived almost exclusively from studies of able-bodied users (Keates et al., 1999). However, such users are only one point on a wide and varied ...
  • Using motion-sensing remote controls with older adults 

    von Bruhn Hinné, Thomas; Keates, Simeon (Springer Verlag, 2011)
    This paper examines how motion sensitive remote control devices can improve the usability of television sets for older adults. It investigates the use of a pointing remote control where the actions are read and selected ...
