  • Establishing design best practices for users with cognitive and learning difficulties 

    Keates, Simeon; Varker, Philip (Springer Verlag, 2007)
    In many respects, cognitive difficulties and learning impairments are the poor relation of Universal Access (UA) research. Research into emotional impairments is even less common. A simple review of almost any general UA ...
  • Gestures and multimodal input 

    Keates, Simeon; Robinson, Peter (Taylor & Francis, 1999)
    For users with motion impairments, the standard keyboard and mouse arrangement for computer access often presents problems. Other approaches have to be adopted to overcome this. In this paper, we will describe the development ...
  • Human-machine design considerations in advanced machine-learning systems 

    Keates, Simeon; Varker, P.; Spowart, F. (International Business Machines Corporation (IBM)/IEEE, 2011-09)
    This paper explores issues related to human–computer interaction with the new class of machine-learning systems that represent an exciting development on the frontiers of information technology. These systems represent a ...
  • Improving Web accessibility through an enhanced open-source browser 

    Hanson, V. L.; Brezin, J. P.; Crayne, S.; Keates, Simeon; Kjeldsen, R.; Richards, J. T.; Swart, C.; Trewin, S. (International Business Machines Corporation/IEEE, 2005)
    The accessibility Works project provides software enhancements to the Mozilla™ Web browser and allows users to control their browsing environment. Although Web accessibility standards specify markup that must be incorporated ...
  • Inclusive design for ordinary users in extraordinary circumstances 

    Keates, Simeon (Springer Verlag, 2009)
    Universal access is commonly interpreted as focusing on designing for users with atypical requirements – specifically users with disabilities or older adults. However, universal access is also about providing access to ...
  • Individual responses to a method of cursor assistance 

    Trewin, Shari; Keates, Simeon; Moffatt, Karyn (Informa Healthcare, 2008-01)
    Purpose. The aim of this study was to evaluate a new click assistance technique, Steady Clicks, designed to help computer users with motor impairments to click more accurately using a mouse. Specifically, Steady Clicks ...
  • Investigating perceptions of manufacturers and retailers to inclusive design 

    Dong, Hua; Clarkson, P. John; Ahmed, Saeema; Keates, Simeon (Berg Publishers, 2004-11)
    This paper describes a study into industry perceptions of barriers and drivers for inclusive design. The study investigated perceptions of manufacturers and retailers of consumer products in the United Kingdom (UK) and ...
  • Motor impairments and universal access 

    Keates, Simeon (Taylor & Francis, 2009)
  • 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 ...
  • Pragmatic research issues confronting HCI practitioners when designing for universal access 

    Keates, Simeon (Springer Verlag, 2006-11)
    Many HCI products exclude potential users unnecessarily. Such exclusion often arises because of a mismatch between designers’ perceptions of the wants and needs of the end-user and their actual wants and needs. Sometimes ...
  • 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 ...
