The study was conducted by experts from the British University of Plymouth. It was attended by 44 people aged 18 to 56 years. They had to carry the smartphone in a bag on their belt for seven to ten days. While they went about their daily activities, the phone’s gyroscope and accelerometer measured and recorded their characteristic walking movements.
Each participant performed about 4000 exercises during the entire test period. Based on the recordings, a unique combination of movements was formed for each person. Scientists tried to identify the participants by it. On average, they were able to do this with an accuracy of 85%. The researchers believe the results could be significantly improved.
