A framework of imitative behavior analysis for animal exercise courses via human pose estimation
This study proposes HPE-IBA, a quantitative framework for evaluating imitative behavior in acting education using pose estimation. It collects motion data from students and gorillas, extracts 3D joint coordinates, computes dynamic joint angles, and applies correlation analysis and two-way ANOVA. The framework provides objective assessment, identifies core joints, and examines the effects of training status and gender on imitation performance, particularly in chest-beating and walking imitations, enhancing personalized training strategies.
Executive Impact & AI Opportunity
Problem: Assessment in Animal Exercise courses relies on subjective judgment, leading to inconsistent evaluations and hindering student improvement.
Solution: HPE-IBA framework uses pose estimation, correlation analysis, and ANOVA for quantitative, objective evaluation of imitative behavior.

Feedback Application
Core Joint Identification
Correlation heatmaps reveal high coordination in symmetric joints (e.g., shoulders in chest-beating) and relative independence in asymmetric joints. In walking, hip and knee joints show high coordination.
0.93
High correlation for shoulder joints in chest-beating, indicating strong synchronization.
Impact of Training & Gender
Two-way ANOVA shows training status significantly influences right knee angles in walking and influences right elbow angles in chest-beating, with gender interaction effects.
| Factor | Chest-Beating (Right Elbow) | Walking (Right Knee) |
|---|---|---|
| Training Status | Significant main effect (p=0.0068) | Significant main effect (p=0.0044) |
| Gender | Significant effect (p<0.05) | Weak influence (p=0.4129) |
| Interaction (Training*Gender) | Statistically significant (p<0.01) | Not significant (p=0.6629) |
Quantitative Feedback & Coaching
By quantifying joint angle deviations and analyzing influencing factors, the framework transforms subjective acting critiques into actionable, personalized feedback, improving training efficacy.
Personalized Coaching for Imitation
The HPE-IBA framework enables instructors to provide objective, data-driven feedback on specific joint movements. This moves beyond subjective evaluations, allowing for targeted guidance based on a student's gender and training background. For instance, if a trained female student struggles with right elbow angle variation during chest-beating, the system can highlight this discrepancy against the gorilla model, suggesting focused exercises for that joint. This level of detail was previously impossible, transforming generic instruction into precise, actionable coaching for improved performance skills.
Outcome: Improved student skill acquisition through targeted, data-backed interventions.
