  • Canonical correlation analysis on data with censoring and error information 

    Sun, Jianyong; Keates, Simeon (IEEE, 2013-12)
    We developed a probabilistic model for canonical correlation analysis in the case when the associated datasets are incomplete. This case can arise where data entries either contain measurement errors or are censored (i.e., ...
  • Cognitive and learning difficulties and how they affect access to IT systems 

    Keates, Simeon; Adams, Ray; Bodine, Cathy; Czaja, Sara; Gordon, Wayne; Gregor, Peter; Hacker, Emily; Hanson, Vicki; Kemp, John; Laff, Mark; Lewis, C.; Pieper, M.; Richards, J.; Rose, D.; Savidis, A.; Schultz, G.; Snayd, P.; Trewin, S.; Varker, P. (Springer Verlag, 2007-04)
    In October 2005, the IBM Human Ability and Accessibility Center and T.J. Watson Research Center hosted a symposium on “cognitive and learning difficulties and how they affect access to IT systems”. The central premise of ...
  • Cognitive impairments, HCI and daily living 

    Keates, Simeon; Kozloski, James; Varker, Philip (Springer Verlag, 2009)
    As computer systems become increasingly more pervasive in everyday life, it is simultaneously becoming ever more important that the concept of universal access is accepted as a design mantra. While many physical impairments ...
  • Countering design exclusion: bridging the gap between usability and accessibility 

    Keates, Simeon; Clarkson, P. J. (Springer Verlag, 2003-10)
    It is known that many people are being excluded unnecessarily from using products, services and environments that are essential for supporting independence and quality of life. Such exclusion often arises from designers ...
  • Critical user forums: an effective user research method for inclusive design 

    Dong, Hua; Clarkson, P. John; Cassim, Julia; Keates, Simeon (Berg Publishers, 2005-07)
    Inclusive or universal design is about designing more accessible products and services for the widest possible range of users, regardless of age and capabilities. It requires better understanding and empathy with all ...
  • Design for participation: providing access to e-information for older adults 

    Keates, Simeon; Clarkson, P. John; Robinson, Peter (Springer Verlag, 2004-06)
    Electronic information sources are becoming increasingly more prolific and offer a huge potential for those able to use them. However, for those unable to access those services, there is the risk of being further disadvantaged ...
  • Designing user interfaces for “ordinary users in extraordinary circumstances”: a keyboard-only web-based application for use in airports 

    Keates, Simeon (Springer-Verlag, 2013-06)
    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 users ...
  • Developing a practical inclusive interface design approach 

    Keates, Simeon; Clarkson, P. John; Robinson, Peter (Elsevier, 2002-07)
    It is known that many products, both software and hardware, are not accessible to large sections of the population. Designers instinctively design for able-bodied users and are either unaware of the needs of users with ...
  • eHealth and the internet of things 

    Ball, Leslie D.; Szymkowiak, Andrea; Keates, Simeon; Bradley, David; Brownsell, Simon (SciTePress - Science and Technology Publications, 2013)
    To respond to an ageing population, eHealth strategies offer significant opportunities in achieving a balanced and sustainable healthcare infrastructure. Advances in technology both at the sensor and device levels and in ...
  • 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)

  • Pragmatic research issues confronting HCI practitioners when designing for universal access 

    Keates, Simeon (Springer Verlag, 2006-11)
