Treffer: ArGaze: An Open and Flexible Software Library for Gaze Analysis and Interaction

Gaze analysis has evolved into a mature technique with diverse applications enabling theinvestigation of various human activities and cognitive processes such as reading, visualattention, memory as well as real time gaze interaction. However, existing proprietarysoftware or librairies often lacks the flexibility needed to incorporate emerging gaze metricsor real time processing, limiting researchers to predefined methodologies.To address these limitations, we introduce ArGaze, an open and flexible softwarelibrary designed to provide a unified and modular approach to gaze analysis or gazeinteraction. ArGaze facilitates real-time and/or post-processing analysis for bothscreen-based and head-mounted eye tracking systems. By offering a wide array of gazemetrics and supporting easy extension to incorporate additional metrics, ArGazeempowers researchers and practitioners to explore novel analytical approaches efficiently.This paper first reviews existing software solutions and their functionalities beforedelving into the design principles and features of the ArGaze library. Subsequently, threeuse cases demonstrate ArGaze’s efficacy in processing eye data from screen-based andhead-mounted eye trackers, showcasing its versatility and applicability across differentresearch and practical contexts.
