DESCRIPTION:Research on simulating user behaviour to predict machine perfo
 rmance was originally started during mid 40s. Computational psychologists 
 pioneered in modelling the mind by considering it as an ensemble of proces
 ses or programs. This stream of research gained much practical importance 
 with the introduction and popularity of the interactive computer systems i
 n mid 80s. There were numerous attempts during the past two decades to sim
 ulate users’ behaviour for computers and other digital electronic applia
 nces. However\, most researches ignored users with disabilities due to the
  diverse range of abilities. My research has added a new dimension in cogn
 itive modelling by including users with disabilities.  In particular\, I h
 ave developed a simulator that can predict the likely interaction patterns
  when undertaking a task using a variety of input devices\, and estimate t
 he time to complete the task in the presence of different disabilities. In
  this talk\, I shall describe different components of the simulator in det
 ail.  I shall also present my investigation on tracking eye gaze patterns 
 of people with visual impairment and on evaluating the effect of hand stre
 ngth on pointing performance of people with motor-impairment. I shall conc
 lude by discussing the implications and limitations of my study from a bro
 ad perspective of interactive system design and user modelling.
