Signals of Success and Struggle: Early Prediction and Physiological Signatures of Human Performance across Task Complexity

ArXi:2603.18798v1 Announce Type: new User performance is crucial in interactive systems, capturing how effectively users engage with task execution. Prospectively predicting performance enables the timely identification of users struggling with task demands. While ocular and cardiac signals are widely used to characterise performance-relevant visual behaviour and physiological activation, their potential for early prediction and for revealing the physiological mechanisms underlying performance differences remains underexplored.
