Wrist Sensor Fusion Enables Robust Gait Quantification across Walking Scenarios



Quantifying step abundance via single wrist-worn accelerometers is a common approach for encouraging active lifestyle and tracking disease status. Nonetheless, step counting accuracy can be hampered by fluctuations in walking pace or demeanor. Here, we assess whether the use of various sensor fusion techniques, each combining bilateral wrist accelerometer data, may increase step count robustness...
