GazeMetro: A Gaze-Based Interactive System for Metro Map

In this paper, we propose a gaze-based interactive system for metro map named GazeMetro, which helps explore and interact with the metro map only by eye movements, providing a new experience of interaction. The objective of GazeMetro is to provide metro map viewers with gaze-based interactions to search the metro map without other manual operations. We implement GazeMetro with 4 gaze-based interaction techniques which are Gaze Fisheye, Gaze Scaling and Panning, Gaze Selection and Gaze Hint. We conducted an experiment to evaluate GazeMetro and the results showed a positive evaluation in pragmatic quality and especially in hedonic quality.
