Hand eye coordination patterns in target selection

In this paper, we describe the use of eye gaze tracking and trajectory analysis in the testing of the performance of input devices for cursor control in Graphical User Interfaces (GUIs). By closely studying the behavior of test subjects performing pointing tasks, we can gain a more detailed understanding of the device design factors that may influence the overall performance with these devices. Our Results show there are many patterns of hand eye coordination at the computer interface which differ from patterns found in direct hand pointing at physical targets (Byrne, Anderson, Douglass, & Matessa, 1999).
