 The dataset is constructed based on existing egocentric 4D resources, building upon [ADT](https://arxiv.org/abs/2306.06362) and [THUD++](https://arxiv.org/abs/2412.08096). Our main contribution lies in the **large-scale, task-driven QA annotations**, which enable fine-grained spatio-temporal reasoning in dynamic egocentric scenes.
