The data are stored in a zip file. The zip file contains
Both Train and Test folder contains text files with raw sensor signals. The Train folder also contains a file names labels_train.txt that specifies which segments of the signals correspond to which activities.
The dataset consists of ================= - Files with Inertial sensor data: Raw triaxial signals from the accelerometer and gyroscope of all the trials with with participants. - A file with labels of all the performed activities. The dataset includes the following files: ========================================= - 'README.txt' - 'RawData/Train/acc_expXX_userYY.txt': The raw triaxial acceleration signal for the experiment number XX and associated to the user number YY. Every row is one acceleration sample (three axis) captured at a frequency of 50Hz. - 'RawData/Train/gyro_expXX_userYY.txt': The raw triaxial angular speed signal for the experiment number XX and associated to the user number YY. Every row is one angular velocity sample (three axis) captured at a frequency of 50Hz. - 'RawData/labels.txt': include all the activity labels available for the dataset (1 per row). Column 1: experiment number ID, Column 2: user number ID, Column 3: activity number ID Column 4: Label start point (in number of signal log samples (recorded at 50Hz)) Column 5: Label end point (in number of signal log samples) Notes: ====== - The units used for the accelerations (total and body) are 'g's (gravity of earth -> 9.80665 m/seg2). - The gyroscope units are rad/seg. - A video of the experiment including an example of the 6 recorded activities with one of the participants can be seen in the following link: http://www.youtube.com/watch?v=XOEN9W05_4A License: ======== Use of this dataset in publications must be acknowledged by referencing the following publications - Jorge-L.
