## 🔍 Overview
we introduce <strong>EOC-Bench</strong>, an innovative benchmark designed to systematically evaluate object-centric embodied cognition in dynamic egocentric scenarios.
Specially, <strong>EOC-Bench</strong> features 3,277 meticulously annotated QA pairs categorized into three temporal categories: Past, Present, and Future, covering 11 fine-grained evaluation  dimensions and 3 visual object referencing types.
To ensure thorough assessment, we develop a  mixed-format human-in-the-loop annotation framework with four types of questions and design a novel multi-scale temporal accuracy metric for open-ended temporal evaluation.
