## 📌 Introduction

**TeleEgo** is a comprehensive **omni benchmark** designed for **multi-person, multi-scene, multi-task, and multimodal long-term memory reasoning** in egocentric video streams.
It reflects realistic personal assistant scenarios where continuous egocentric video data is collected across hours or even days, requiring models to maintain and reason over **memory, understanding, and cross-memory reasoning**. **Omni** here means that TeleEgo covers the full spectrum of **roles, scenes, tasks, modalities, and memory horizons**, offering all-round evaluation for egocentric AI assistants.

**TeleEgo provides:**

- 🧠 **Omni-scale, diverse egocentric data** from 5 roles across 4 daily scenarios.
- 🎤 **Multi-modal annotations**: video, narration, and speech transcripts.
- ❓ **Fine-grained QA benchmark**: 3 cognitive dimensions, 12 subcategories.

## Download

```bash
# Extract (only need to specify the first file)
7z x archive.7z.001

# Or extract to a specific directory
7z x archive.7z.001 -o./extracted_data
```

## Dataset Structure

## Alternative Download Methods

If you have difficulty accessing Hugging Face, you can also download the dataset from:

**Baidu Netdisk (百度网盘)**
```
Link: https://pan.baidu.com/s/1TSqfjqeaXdP2TWEpiy_3KA?pwd=7wmh
```

The Baidu Netdisk version contains the **uncompressed data files** (MP4 videos and JSON annotations) directly


## 🧪 Benchmark Tasks

TeleEgo-QA evaluates models along **three main dimensions**:

1. **Memory**
   - Short-term / Long-term / Ultra-long Memory
   - Entity Tracking
   - Temporal Comparison & Interval

2. **Understanding**
   - Causal Understanding
   - Intent Inference
   - Multi-step Reasoning
   - Cross-modal Understanding

3. **Cross-Memory Reasoning**
   - Cross-temporal Causality
   - Cross-entity Relation
   - Temporal Chain Understanding

Each QA instance includes:

- Question type: Single-choice, Multi-choice, Binary, Open-ended
