Peanuttoad/StreamGaze_v2

StreamGaze Dataset

StreamGaze is a comprehensive streaming video benchmark for evaluating MLLMs on gaze-based QA tasks across past, present, and future contexts.

Companion dataset: The EgoGazeVQA dataset is hosted separately at Peanuttoad/gaze_dataset.

🎯 Task Categories

Past (Historical Context)

• Gaze Sequence Matching: Match gaze patterns to action sequences
• Non-Fixated Object Identification: Identify objects outside gaze
• Object Transition Prediction: Predict object state changes
• Scene Recall: Recall scene details from memory

Present (Current Context)

• Object Identification (Easy/Hard): Identify objects in/outside FOV
• Object Attribute Recognition: Recognize object attributes
• Future Action Prediction: Predict upcoming actions

Proactive (Future-Oriented)

• Gaze-Triggered Alert: Alert based on gaze patterns
• Object Appearance Alert: Alert on object appearance

• scene_caption: Scene description
• action_caption: Action description

📝 QA Format

Each QA JSON file contains:
