Research on Classroom Behavior Analysis and Quantitative Evaluation System of Student Attention Based on Computer Vision
Revolutionizing Online Education with AI-Powered Attention Analysis
This paper presents a novel deep learning-based system for analyzing student classroom behavior and quantitatively evaluating attention using computer vision. It addresses the growing need for objective assessment in online education by tracking multimodal behaviors like facial expressions, head posture, body movements, and eye gaze. The system leverages advanced techniques such as the Swin Transformer and ViT decoder for gaze estimation and the Analytic Hierarchy Process (AHP) for comprehensive scoring. It aims to provide real-time feedback to teachers and students, improving learning outcomes by identifying and correcting engagement issues. Experimental results confirm the system's accuracy in assessing student engagement, offering valuable insights for educators and promoting student academic development. This solution offers a scalable and objective alternative to traditional subjective evaluation methods.

Core Methodology
The core methodology involves a multimodal approach to capture student behavior. It utilizes computer vision to detect facial expressions, head posture, body movements, and eye gaze. A key innovation is the Learner Gaze Estimation Method Based on Sliding Window Self-Attention Mechanism, which uses a cross-encoder-decoder structure with Swin Transformer and ViT models to accurately track student gaze and determine focus. This moves beyond simple presence detection to nuanced engagement analysis.
Quantitative Evaluation
The system employs a multi-level comprehensive evaluation system that quantifies student attention across four dimensions: facial fatigue/alertness, head focus, emotional receptivity, and behavioral involvement. The Analytic Hierarchy Process (AHP) is used to integrate these factors with weighted analysis, providing a numerical standard for attention. The PAD model is applied for emotional quantification. This framework moves from raw behavioral data to actionable, quantifiable engagement scores.
Practical Application & Impact
The system offers significant practical benefits for online education. It provides real-time feedback to teachers, enabling them to adjust teaching strategies dynamically. Students receive timely reflection on their learning behaviors, fostering self-correction and optimal learning results. The experimental results, including data on facial fatigue (yawns/blinks) and head focus (pitch/yaw/roll angles), demonstrate the system's ability to accurately assess engagement and identify disengaged students, thereby supporting academic development.

Experimental Validation Highlights
The system was validated using data from online learning sessions. Quantitative scoring demonstrated strong correlation with actual student engagement. For instance, in head focus detection, significant score reductions were observed for students whose head angles exceeded thresholds, accurately identifying disengagement. The overall classroom participation score derived from the system showed only a ~1.43% deviation from human judgment, indicating high reliability and confidence. This validation confirms the system's ability to provide a robust and objective measure of student attention.
