The present study investigates the development, integration, and evaluation of AI‑driven avatars within emotionally adaptive virtual classrooms. Over recent years, online education has grown exponentially, distinguishing itself through scalability and accessibility yet often lacking the nuanced emotional support integral to effective learning. To address this gap, we leverage advances in affective computing and pedagogical agent design to create avatars that detect and adapt to learners’ emotional states in real time. Specifically, our system uses multimodal sensors—facial expression analysis, vocal tone recognition, and interaction metrics—to infer discrete emotions such as confusion, frustration, boredom, and engagement. These inferences inform the avatar’s adaptive behaviors, including modulating speech prosody, delivering empathetic dialogue, adjusting pacing, and providing timely encouragement. We implemented this prototype in Unity3D, integrating the OpenFace facial‑action‑unit toolkit and an open‑source speech‑emotion classifier. A mixed‑methods experiment was conducted with 120 undergraduate students, randomly assigned to either an Adaptive Avatar condition or a Control (non‑adaptive) condition. The Adaptive group’s avatars responded dynamically to affective cues, whereas Control avatars presented identical content without adaptation. Quantitative measures included a 10‑item post‑test for knowledge retention, the User Engagement Scale for affective engagement, and interaction logs (time‑on‑task, hint requests). Qualitative data were gathered via semi‑structured interviews exploring perceptions of empathy, support, and social presence. Results indicate that learners in the Adaptive condition achieved significantly higher retention (M = 8.2 vs. 7.1, p < .001), reported greater engagement (M = 4.1 vs. 3.6 on a 5‑point scale, p < .001), requested fewer hints, and spent more time on task.
