Cover Story: Accurate estimation of cognitive load is critical for developing adaptive human–computer interfaces that respond in real time to users’ mental states. Eye movements, especially smooth pursuit tracking, provide a valuable, non-invasive indicator of cognitive effort. This work introduces a framework that leverages smooth pursuit eye movements to estimate workload without predefined target trajectories. Two trajectory-independent methods, validated on benchmark datasets, reliably detect cognitive fluctuations. A federated learning architecture preserves privacy while enabling scalable, collaborative model updates. This solution supports real-time cognitive monitoring for applications in AR, automotive, and education. View this paper
