Daily Living Activity Recognition Using Wearable Devices: A Features-rich Dataset and a Novel Approach

This dataset contains three-axial accelerometer, magnetometer, and gyroscope data recorded from different parts of the body: dominant wrist, hip, and ankle while performing 17 different daily-life activities. All data were recorded with medical-grade devices at a high sampling frequency (up to 256Hz). The dataset includes data of 8 volunteers, aged between 23-37, with a weight between 52-90 kg and height between 172-186 cm. All the subjects were healthy. Each person performed 17 different activities: (Set A Activities): RELAX, KEYBOARD, LAPTOP, HANDWRITING, HANDWASHING, FACEWASHING, TEETHBRUSH, SWEEPING, VACUUMING, EATING, DUSTING, RUBBING (Set B Activities): DOWNSTAIRS, WALKING, WALKING FAST, UPSTAIRS, UPSTAIRS FAST Set A activities have been performed for a fixed time, while Set B not. In particular, Set A activities have been performed for more than 120 seconds (in general for about 150 seconds), and we labelled in the dataset the central 120 seconds of each execution in order to obtain cleaner data. On the other hand, Set B includes: WALKING performed for 160 meters (in at least 110 seconds); WALKING_FAST performed for 205 meters (in at least 110 seconds); DOWNSTAIRS, UPSTAIRS, UPSTAIRS_FAST performed using a single flight of stairs with no intermediate floors between the steps for an average time of 40 seconds. While performing these activities, the subjects were wearing these three devices with the following settings: 1 Actigraph Centrepoint at the dominant wrist. Accelerometer recording at a sampling rate of 256Hz 1 Actigraph GT9X Link at the right hip at the height of the iliac crest (using the device belt clip). IMU (i.e., accelerometer, magnetometer, and gyroscope) recording at a sampling rate of 100Hz. 1 Actigraph GT9X Link at the height of the right ankle placed, with the help of the belt clip, on the subject's right side of the shoe, over the malleolus. IMU recording at a sampling rate of 100Hz. In any work using this dataset cite the related publication. The publication reports detailed information concerning the procedure followed for recording the dataset. Additional information and detailed biometric data of each subjects are, respectively, in the README.txt and subjects_info.csv files.本数据集收录了受试者在开展17项不同日常活动时，于身体三个部位（优势手手腕、髋部及踝部）采集的三轴加速度计（three-axial accelerometer）、磁力计（magnetometer）与陀螺仪（gyroscope）数据。所有数据均采用医疗级设备以高采样频率录制，最高采样率可达256Hz。 本数据集共纳入8名健康志愿者，年龄介于23至37岁，体重区间为52至90千克，身高区间为172至186厘米。每名受试者需完成17项日常活动，分为A、B两组： A组活动：放松（RELAX）、键盘操作（KEYBOARD）、笔记本电脑操作（LAPTOP）、手写（HANDWRITING）、洗手（HANDWASHING）、洗脸（FACEWASHING）、刷牙（TEETHBRUSH）、扫地（SWEEPING）、吸尘（VACUUMING）、进食（EATING）、除尘（DUSTING）、揉搓动作（RUBBING）； B组活动：下楼（DOWNSTAIRS）、步行（WALKING）、快走（WALKING FAST）、上楼（UPSTAIRS）、快速上楼（UPSTAIRS FAST）。 A组活动均采用固定时长录制，每项活动的录制时长超过120秒（通常约150秒）；为获取更纯净的有效数据，我们将每次活动执行过程中的中央120秒片段标注至数据集中。B组活动无固定时长要求：其中步行活动需完成160米（耗时至少110秒），快走活动需完成205米（耗时至少110秒）；下楼、上楼及快速上楼活动均采用单段无中间楼层的楼梯进行，平均耗时约40秒。 受试者佩戴三台设备，具体设置如下： 1. 优势手手腕处佩戴1台Actigraph Centrepoint设备，其加速度计采样率为256Hz； 2. 右侧髋部髂嵴高度处佩戴1台Actigraph GT9X Link设备（借助设备自带腰带夹固定），其内置惯性测量单元（Inertial Measurement Unit, IMU，包含加速度计、磁力计与陀螺仪）采样率为100Hz； 3. 右侧外踝上方鞋侧位置佩戴1台Actigraph GT9X Link设备（借助腰带夹固定），其内置IMU采样率为100Hz。 使用本数据集进行的任何研究工作，均需引用相关发表文献，该文献详细记录了本数据集的录制流程。额外说明信息及每名受试者的详细生物特征数据，分别存放在README.txt与subjects_info.csv文件中。
