=================================================================================================== Smartphone-Based Recognition of Human Activities and Postural Transitions Data Set Version 2.1 =================================================================================================== Jorge L. Reyes-Ortiz(1,2), Davide Anguita(1), Luca Oneto(1) and Xavier Parra(2) 1 - Smartlab, DIBRIS - Università degli Studi di Genova, Genoa (16145), Italy. 2 - CETpD - Universitat Politècnica de Catalunya. Vilanova i la Geltrú (08800), Spain har '@' smartlab.ws www.smartlab.ws =================================================================================================== The experiments were carried out with a group of 30 volunteers within an age bracket of 19-48 years. They performed a protocol of activities composed of six basic activities: three static postures (standing, sitting, lying) and three dynamic activities (walking, walking downstairs and walking upstairs). The experiment also included postural transitions that occurred between the static postures. These are: stand-to-sit, sit-to-stand, sit-to-lie, lie-to-sit, stand-to-lie, and lie-to-stand. All the participants were wearing a smartphone (Samsung Galaxy S II) on the waist during the experiment execution. We captured 3-axial linear acceleration and 3-axial angular velocity at a constant rate of 50Hz using the embedded accelerometer and gyroscope of the device. The experiments were video-recorded to label the data manually. The obtained dataset was randomly partitioned into two sets, where 70% of the volunteers was selected for generating the training data and 30% the test data. 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.
