This dataset comprises motion sensor data from 115 subjects, each one with at least two acquisition sessions in different days. Data were captured using commercial smartphones, being recorded accelerometer and rotation vector signals. During a session, the corresponding subject held the mobile device in their pocket or waist and was requested to walk freely for five minutes. At the end of each session, accelerometer and rotation vector data acquired were stored in different files. The acquisition application adopted a sampling frequency of 40 Hz.Raw data are provided in the folder named `raw_data`, containing one txt file for accelerometer capture, for each session and user, and another corresponding rotation sensor capture in another txt file. Files are named as: ___session__data_.txt. Each row consists in a sensor reading, with the first column being the timestamp. The transformed data to user coordinates are provided in the folder `user_coordinates` following similar notation for the files. In this case, only transformed accelerations are provided, being named as `data_user_coord` in txt files.
