# StreamGaze Dataset

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

## 🎯 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

## 📥 Usage

### Extract Videos

```bash
# Extract EGTEA videos
tar -xzf videos_egtea_original.tar.gz -C videos/egtea/original/
tar -xzf videos_egtea_viz.tar.gz -C videos/egtea/viz/

# Extract EgoExoLearn videos
tar -xzf videos_egoexolearn_original.tar.gz -C videos/egoexolearn/original/
tar -xzf videos_egoexolearn_viz.tar.gz -C videos/egoexolearn/viz/

# Extract HoloAssist videos
tar -xzf videos_holoassist_original.tar.gz -C videos/holoassist/original/
tar -xzf videos_holoassist_viz.tar.gz -C videos/holoassist/viz/
```

## 🔑 Metadata Format

Each metadata CSV contains:
- `video_source`: Video identifier
- `fixation_id`: Fixation segment ID
- `start_time_seconds` / `end_time_seconds`: Temporal boundaries
- `center_x` / `center_y`: Gaze center coordinates (normalized)
- `representative_object`: Primary object at gaze point
- `other_objects_in_cropped_area`: Objects within FOV
- `other_objects_outside_fov`: Objects outside FOV
- `scene_caption`: Scene description
- `action_caption`: Action description 

## 📝 QA Format

Each QA JSON file contains:
```json
  {
    "response_time": "[00:08 - 09:19]",
    "questions": [
      {
        "question": "Among {milk, spoon, pan, phone}, which did the user never gaze at?",
        "time_stamp": "03:14",
        "answer": "A",
        "options": [
          "A. milk",
          "B. spoon",
          "C. pan",
          "D. phone"
        ],
      }
    ],
    "video_path": "OP01-R03-BaconAndEggs.mp4"
  }
```
