Evaluating programming proficiency has become more relevant as the demand for coding skills has increased. Current methods, such as questionnaires or interviews, are methods that lack intuition, flexibility, and real-time capabilities. In our work, we investigate eye gaze behavior as an estimate for skill assessment. Specifically, we conducted a study (N=14) using an eye tracker to analyze the participants’ abilities to understand source code by presenting them with a series of programs. We evaluated their eye movements based on common eye tracking metrics and identified mutual task-solving strategies among the participants. While we cannot relate these indicators to programming proficiency directly, this study serves as an evaluation of real-time methods for evaluating programming proficiency.
