Abstract

We present a method to calibrate an eye-tracking system based on cockpit interactions of a pilot. Many studies show the feasibility of implicit calibration with specific interactions such as mouse clicks or smooth pursuit eye movements. In real-world applications, different types of interactions often co-exist in the “natural” operation of a system. Therefore, we developed a method that combines different types of interaction to enable implicit calibration in operational work environments. Based on a preselection of calibration candidates, we use an algorithm to select suitable samples and targets to perform implicit calibration. We evaluated our approach in an aircraft cockpit simulator with seven pilot candidates. Our approach reached a median accuracy between 2° to 4° on different cockpit displays dependent on the number of interactions. Differences between participants indicated that the correlation between gaze and interaction position is influenced by individual factors such as experience.
