Help us complete this description Edit
This dataset contains smartphone sensors data for six physical activities. The data was collected using four participants. Moreover, each participant was provided with 4 smartphones on four body positions ( jeans pocket, arm, wrist, belt) so data was collected for each activity on these 4 positions. The activities were walking, running, standing, sitting, and walking upstairs and downstairs. Data was collected for three smartphone sensors (an accelerometer, a gyroscope, a magnetometer) at 50 samples per second. Further details can be found in the readme file in dataset archive.
