GazeLLE-v3: State-of-the-art Gaze Estimator
GazeCoT leverages an improved gaze estimation model, GazeLLE-v3, built on the powerful DINOv3 backbone. This enhancement is crucial for accurately extracting fine-grained head and eye features, which previous models struggled with, leading to robust gaze target predictions.
| Model | Backbone | AUC (↑) | Avg. L2 (↓) | Min L2 (↓) |
|---|---|---|---|---|
| Human [106] | N/A | 0.924 | 0.096 | 0.040 |
| GazeLLE-L [106] | DINOv2-ViT-L | 0.958 | 0.099 | 0.041 |
| GazeLLE-v3-H (Ours) | DINOv3-ViT-H+ | 0.960 | 0.093 | 0.038 |
Enhanced Gaze Target Recognition
GazeCoT demonstrates a significant leap in MLLMs' ability to accurately infer gaze targets. This is a foundational step for unlocking advanced social intelligence in multimodal AI systems.

Ablation Study: Contributions of GazeCoT Components
Our ablation studies confirm that all components of the GazeCoT pipeline – GazeLLE-v3, the ROI description tool, and the structured CoT reasoning context – contribute to overall performance, especially in complex social intelligence scenarios where detailed context and careful management are critical.
| Condition (GPT-4.1) | Gaze Target Accuracy (%) | GSI Accuracy (%) |
|---|---|---|
| Baseline | 43.95 | 58.85 |
| GazeCoT (full pipeline) | 68.43 | 69.79 |
| GazeCoT (w/o ROI description) | 68.65 | 67.29 |
| GazeCoT (w/o structured context) | 69.53 | 60.63 |
Transforming Human-AI Interaction: Parent-Child JME Analysis
In a real-world user study involving parent-child joint media engagement (JME) analysis, GazeCoT significantly improved field note quality, explainability, and trustworthiness. Experts noted its superior ability to capture and analyze shifts in joint attention, validating gaze as a crucial social cue.
Case Study Highlight: Improved Field Notes
One participant (P1) commended GazeCoT’s ability to "find brief gaps in joint attention" that humans might miss, allowing for more insightful analysis. Another (P2) noted GazeCoT uses gaze to analyze joint engagement, which is "consistent with my own way of analyzing these clips," increasing trust in the system. These insights highlight GazeCoT's role in aligning AI's social perception and reasoning with human norms.
Impact: Better descriptions of interaction dynamics, accurate timestamping, and actionable advice for parents, making previously out-of-reach tasks possible.
Broadening HCI Application Horizons
GazeCoT's plug-and-play nature and robust gaze-informed reasoning unlock new possibilities across various HCI domains:
- Human-Robot Interaction (HRI): Enables robots to better decode user intent from gaze, leading to more intuitive and proactive assistance.
- Workplace Collaboration: Improves modeling of joint attention and mutual awareness in physical spaces, enhancing AI moderation of discussions.
- Early Childhood Education: Allows for open-ended, socially-aware content generation for analyzing and supporting child development.
- Accessibility Applications: Expands visual descriptions for blind and low-vision users to include non-verbal social dynamics.
- Creativity & Performative Applications: Models audience and performer attention, providing feedback for improving performance.
Ethical Implications: Balancing Innovation with Responsibility
While GazeCoT offers powerful social intelligence, its ability to perceive and interpret gaze raises significant ethical considerations, particularly regarding privacy and potential for surveillance. We categorize applications into two types:
| Application Type | Description | Ethical Considerations & Mitigation |
|---|---|---|
| Cooperative | Users proactively initiate the application and directly benefit (e.g., HRI, personal AI assistants). |
|
| Non-cooperative | Individuals' gaze/cognitive state analyzed without their proactive input or direct benefit (e.g., advanced security/employee surveillance). |

Key Limitations and Future Directions
- Latency & Cost: ROI description adds inference delay and token cost. Future work includes pipeline optimization (e.g., skipping ROI for simple tasks, local MLLMs, streaming output).
- Face vs. Head Detection: Current face detection model struggles with non-camera-facing individuals. Transitioning to robust head detection or using GazeLLE-v3 as-is (which handles non-facing individuals) is a future improvement.
- User Study Scope: Limited to one scenario (parent-child JME) and expert users. Future work will involve more diverse scenarios and user populations.
- MLLM Training Data: GazeCoT can be adapted to generate fine-grained captions on gaze and social interaction, mitigating the lack of gaze-related training data for future MLLM development.
