Effective signaling in e-learning, such as using digital pointers, can guide attention and improve learning. This study investigated how gaze behavior and the distance between gaze and pointer influence learning outcomes across three experiments. We first examined the relationship between gaze alignment with the pointer and quiz performance, finding that alignment reliably predicted performance (Experiment 1). Next, we evaluated the effects of signaling design, observing that precise synchronization of pointer movements with auditory content decreased gaze alignment and impaired performance predictions (Experiment 2). Finally, we demonstrated that gaze-pointer distance robustly predicts quiz performance in natural pointer conditions without forced synchronization (Experiment 3). These findings highlight gaze-pointer alignment as a critical factor in e-learning and underscore its potential for developing automated adaptive feedback systems to optimize learning experiences.
