Raw accelerometer data of 4 subjects, collected during a walk. Data were recorded on an iPhone 13 device, using Arduino Science Journal app. The data from the accelerometer includes the acceleration along the x-axis, y-axis, and z-axis. These axes capture the horizontal movement of the user (x-axis), forward/backward movement (y-axis), and upward/downward movement (z-axis).Each subject carried the phone in their right pant pocket during the walk. This dataset was used for a university project whose aim was to identify subjects by their walk using machine learning methods.
