smartphone-and-smartwatch-activity-and-biometrics-15m6
收藏资源简介:
这是一个包含156万样本的多设备时间序列语料库,捕捉了51名志愿者在执行18种活动时智能手机和智能手表上的3轴加速度计和陀螺仪读数。每位参与者在佩戴智能手机和智能手表的情况下,每种活动进行三分钟,产生了同步的传感器数据流,采样率为20赫兹。每条记录格式为:- subject-id:唯一标识符(1600-1650)- activity-code:表示18种活动的单个字母代码(A-S,不包括N,例如:走路、刷牙)- timestamp:Unix时间戳(秒)- x, y, z:给定轴的原始传感器值。数据集分为四个目录(phone-acc、phone-gyro、watch-acc、watch-gyro),每个目录包含51个每个参与者的文件。提供了原始数据以及10秒滑动窗口特征向量,可用于活动识别和行为生物特征建模。
This is a multi-device time-series corpus containing 1.56 million samples, which captures 3-axis accelerometer and gyroscope readings from smartphones and smart watches worn by 51 volunteers while they performed 18 distinct activities. Each participant wore both a smartphone and a smart watch, and completed each activity for 3 minutes, generating synchronized sensor data streams with a sampling rate of 20 Hz. Each record follows the format: - subject-id: Unique identifier (ranging from 1600 to 1650) - activity-code: Single-letter code (A-S, excluding N) representing the 18 activities (e.g., walking, brushing teeth) - timestamp: Unix timestamp (in seconds) - x, y, z: Raw sensor values for the respective axes. The dataset is divided into four directories: phone-acc, phone-gyro, watch-acc and watch-gyro, each of which contains 51 files, one per participant. Both raw sensor data and 10-second sliding window feature vectors are provided, which can be used for activity recognition and behavioral biometric modeling.
