## AI 摘要

针对可穿戴IMU信号高度依赖设备位置、朝向等具体设置，难以跨设备迁移的挑战，本文提出了AnyMo框架。该框架首先基于物理原理进行IMU仿真，在身体表面密集采样生成多样合成信号，用于预训练图编码器。随后，将多位置IMU信号转化为全身运动标记，并与大语言模型对齐以理解运动语义。实验表明，AnyMo在未见过的14个下游数据集的零样本活动识别、跨模态检索及运动描述三项任务上均取得显著提升，证明了其作为野外可穿戴运动理解通才模型的潜力。

As wearable and mobile devices become increasingly embedded in daily life, they offer a practical way to continuously sense human motion in the wild. But inertial signals are highly dependent on the sensing setup, including body location, mounting position, sensor orientation, device hardware, and sampling protocol. This setup dependence makes it difficult to learn motion representations that transfer across devices and datasets, and limits the broader use of wearable IMUs beyond closed-set recognition. We introduce AnyMo, a geometry-aware framework for setup-agnostic human motion modeling. AnyMo uses physics-grounded IMU simulation over dense body-surface placements to generate diverse and plausible synthetic signals, pre-trains a graph encoder from paired synthetic placement views and masked partial observations, tokenizes multi-position IMU into full-body motion tokens, and aligns these tokens with an LLM for motion-language understanding. We evaluate AnyMo on three complementary tasks: zero-shot activity recognition across 14 unseen downstream datasets, cross-modal retrieval, and wearable IMU motion captioning, where it improves average Accuracy/F1/R@2 by 11.7\%/11.6\%/22.6\% on HAR, increases zero-shot IMU-to-text and text-to-IMU retrieval MRR by 15.9\% and 28.6\%, respectively, and improves zero-shot captioning BERT-F1 by 18.8\%. These results support AnyMo as a generalist model for wearable motion understanding in the wild. Project page: https://baiyuchen.com/project/AnyMo.
