GSPEED - BLE-based gait speed dataset

Bluetooth Low Energy (BLE) database to evaluate the gait speed of individuals in an in-home environment. The database is composed of several BLE RSSI measurements from different wearable devices and different BLE beacons, corresponding to 382 walks performed by 13 actors. Each row represents an RSSI measurement. The structure of the dataset is as follows: mac: The MAC address of the detected beacon. rssi: The RSSI value obtained for the beacon. device: A four-character descriptor for the smartwatch that performed the scan. timestamp: The time stamp at which the scan was received. user: The id of the user that was performing the experiment. direction: A number (0 or 1) indicating the direction of the walk. walk_id: A number that identifies each walk. speed: The actual speed of the user, in $m/s$.This work was supported in part by the Spanish Ministry of Economy and Competitiveness through projects MICROCEBUS (RTI2018-095168-B-C53/C54), REPNIN+ (TEC2017-90808-REDT) and in part by the Regional Government of Extremadura and the European Regional Development Fund through project GR18038 and the Regional Government of Valencian Community by project AICO/2020/046
