  • Computer-based tools for assessing micro-longitudinal patterns of cognitive function in older adults 

    Brown, Laura J. E.; Adlam, Tim; Hwang, Faustina; Khadra, Hassan; Maclean, Linda M.; Rudd, Bridey; Smith, Tom; Timon, Claire; Williams, Elizabeth A.; Astell, Arlene (Springer, 2016-07-29)
    Patterns of cognitive change over micro-longitudinal timescales (i.e., ranging from hours to days) are associated with a wide range of age-related health and functional outcomes. However, practical issues with conducting ...
  • Movement time for motion-impaired users assisted by force-feedback: effects of movement amplitude, target width, and gravity well width 

    Hwang, Faustina; Keates, Simeon; Langdon, Patrick; Clarkson, P. John (Springer Verlag, 2005-12)
    This paper presents a study investigating how the performance of motion-impaired computer users in point and click tasks varies with target distance (A), target width (W), and force-feedback gravity well width (GWW). Six ...
  • A submovement analysis of cursor trajectories 

    Hwang, Faustina; Keates, Simeon; Langdon, Patrick; Clarkson, P. John (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, Faustina; Langdon, Patrick; Clarkson, P. John; Robinson, Peter (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 ...
