Input devices are an integral part of human and computer interaction. This research explores the relationship between user ability and user performance when using input devices in real tasks in a natural environment. User performances using a mouse, a tablet-with-stylus and a touch screen were measured in browsing and dragging tasks. User cognitive, perceptual and motor abilities were measured usmg widely used and simple psychometric tests. Input devices were rated before and after the tasks. Users provided their justification and described their experience in an interview after completing the task. The psychometric tests, i.e. Mini Mental State Examination for cognitive, Identical Picture for perceptual and Simple Reaction Time for motor abilities, measured user abilities effectively. The result shows that perceptual and motor abilities influence user performance for highly complex tasks. Consistent with previous studies, the mouse is the best device for a dragging task. Content analysis of user justification indicates that users prefer the mouse because of its effectiveness, ease of use and familiarity. User self-reported behaviour illustrates an extended user behaviour model which includes detailed descriptions of the activities. The click in Simple Reaction Time and the first move in the dragging task have been successfully modelled using microstrategies.
