该数据集包含35名健康成年人（实验室环境）和32名（自由生活环境）的大腿佩戴加速度计数据（SENS motion，12.5 Hz，±4 g），并配有视频标注的活动真实标签。数据集涵盖了实验室协议和每人约1小时的标注自由生活活动。数据从原始Zenodo发布版本统一为每名受试者的parquet文件，每行代表一个原始加速度计样本，并附有1 Hz的活动标签。数据集共包含35名参与者，690万样本，40%已标注，标注时长为61.3小时。The dataset contains thigh-worn accelerometry data (SENS motion, 12.5 Hz, ±4 g) with video-labelled activity ground truth in 35 healthy adults (lab) and 32 (free-living), covering both a laboratory protocol and ≈1 h of annotated free-living per subject. Harmonized from the original Zenodo release into per-subject parquet files — one row per raw accelerometer sample, with 1 Hz activity labels asof-joined on. The dataset includes 35 participants, 6.9 M samples, 40% labelled, and 61.3 h labeled.
