axivity-ax6-left-forearm-nondominant

6-axis actigraphy (translation and rotation) using Axivity AX6 (similar to AX3 used in UK BioBank), configured with 100Hz sampling frequency, 16bit resolution and 2000dps gyro/rotation.<br>Attached with a velcro to the exterior of a cotton wrist band with arrow facing down towards the ground/back when arms are in a natural position along the body, on the left forearm (non-dominant arm).<br>Started acquisition in March 2021.<br>Each file represents one acquisition session of about 1 week. Multiple files can be concatenated to study a longer time period.本数据集采用Axivity AX6设备采集6轴活动记录仪（6-axis actigraphy）数据，该设备与英国生物银行（UK BioBank）所使用的AX3设备类似，配置参数为：采样频率100Hz、16位分辨率以及2000度每秒（dps）的陀螺仪旋转量程。 设备通过魔术贴（velcro）固定于棉质腕带外侧，佩戴于左前臂（非优势手臂），当手臂自然垂于身体两侧时，设备箭头朝下指向地面与背部。 数据采集始于2021年3月。 单个文件对应一次为期约1周的采集会话，可将多个文件拼接以研究更长时间跨度的数据集。
