Data Set Information:

PAMAP2体力活动监测数据集包含9名佩戴3个惯性测量装置和心率监测器的受试者进行的18种不同体力活动（如步行、骑自行车、踢足球等）的数据。该数据集可用于活动识别和强度估计，同时开发和应用数据处理、分割、特征提取和分类算法。

** Sensors **
3 Colibri wireless inertial measurement units (IMU):
 - sampling frequency: 100Hz
 - position of the sensors:
      - 1 IMU over the wrist on the dominant arm
      - 1 IMU on the chest
      - 1 IMU on the dominant side's ankle
HR-monitor:
 - sampling frequency: ~9Hz

** Data collection protocol **
Each of the subjects had to follow a protocol, containing 12 different activities. The folder a€?Protocola€? contains these recordings by subject.
Furthermore, some of the subjects also performed a few optional activities. The folder a€?Optionala€? contains these recordings by subject.

** Data files **
Raw sensory data can be found in space-separated text-files (.dat), 1 data file per subject per session (protocol or optional). Missing values are indicated with NaN. One line in the data files correspond to one timestamped and labeled instance of sensory data. The data files contain 54 columns: each line consists of a timestamp, an activity label (the ground truth) and 52 attributes of raw sensory data.

Attribute Information:

The 54 columns in the data files are organized as follows:
 1. timestamp (s)
 2. activityID (see below for the mapping to the activities)
 3. heart rate (bpm)
 4-20. IMU hand
 21-37. IMU chest
 38-54. IMU ankle

The IMU sensory data contains the following columns:
 1. temperature (?°C)
 2-4. 3D-acceleration data (ms-2), scale: ?±16g, resolution: 13-bit
 5-7. 3D-acceleration data (ms-2), scale: ?±6g, resolution: 13-bit
 8-10. 3D-gyroscope data (rad/s)
 11-13. 3D-magnetometer data (??T)
 14-17. orientation (invalid in this data collection)

List of activityIDs and corresponding activities:
1 lying
2 sitting
3 standing
4 walking
5 running
6 cycling
7 Nordic walking
9 watching TV
10 computer work
11 car driving
12 ascending stairs
13 descending stairs
16 vacuum cleaning
17 ironing
18 folding laundry
19 house cleaning
20 playing soccer
24 rope jumping
0 other (transient activities)
