## Introduction
### 🌟 Three distinct problem-solving modes
-  **Backward Tracing**: trace back to past events to answer the question.
-  **Real-Time Visual Perception**: understand and respond to events as they unfold at the current timestamp.
-  **Forward Active Responding**: delay the response until sufficient future information becomes available to answer the question accurately.
