DESCRIPTION:Scientists from many different disciplines (including physiolo
 gy\, psychology\, and engineering) have worked on modelling visual percept
 ion. However this field has been less extensively studied in the context o
 f computer science\, as most existing perception models work only for very
  specific domains such as menu searching or icon searching tasks. We are d
 eveloping a perception model that works for any application. It takes a li
 st of mouse events\, a sequence of bitmap images of an interface and locat
 ions of different objects in the interface as input\, and produces a seque
 nce of eye-movements as output. We have identified a set of features to di
 fferentiate among different screen objects and using those features\, our 
 model has reproduced the results of previous experiments on visual percept
 ion in the context of HCI. It can also simulate the effects of different v
 isual impairments on interaction. Our model of visual impairments are more
  detailed and accurate than the previous models and show probable interact
 ion pattern of visually impaired users.
