Evaluation and Analysis of Eye Gaze Interaction
Abstract
Eye gaze interaction can provide a convenient and natural addition to user-computer dialogues. We have previously reported on our interaction techniques Using eye gaze. In this report, we assess the effectiveness of our approach in a controlled setting. We present two experiments that compare our eye gaze object selection technique with conventional selection by mouse. The results show that for a simple task, it takes 60% less time to select an object with our eye gaze technique than with a mouse. We also use Fitts' Law to investigate the speed and quality differences between eye gaze selection and mouse selection. Our eye gaze selection technique is shown to produce a low slope, more like pure eye movement, which suggests that the technique preserves the inherent speed advantage of the eye over the hand. We find that eye gaze interaction is at least as fast as the mouse and it is convenient in situations where it is important to use the hands for other tasks. It is particularly beneficial for the larger screens, workspaces, and virtual environment of the future, and will become increasingly practical as eye tracker technology matures.
