Abstract:Accelerometry-based activity sensors are nowadays widely deployed in ambulatory monitoring of physical activity. Field experiments are characterized by very little control over usage of the sensor [1]. A malfunctioning sensor, giving output within the range of normal physical activity, will not be noticed based on just the sensor output. A quick and reliable calibration procedure is required [2], focused on determining the relation between that accelerometer output and physical activity across a range of activity levels. The purpose of this study was to design an easy spot-check to monitor the validity and reliability of activity sensors.
