This project will demonstrate a new approach to employing users' gaze in the context of human-computer interaction. This new approach uses gaze passively in order to improve the speed and precision of manually controlled pointing techniques. Designing such gazeaugmented manual techniques requires an understanding of the principles that govern the coordination of hand and eye. This coordination is influenced by situational parameters (task complexity, input device used, etc.), which this project will explore in controlled experiments.
