Step detector or pedometer is used to determine kinetic characteristics during patient activity. Depending on the ability of the pedometer these parameters can be the number of steps, distance, speed, acceleration, etc. This step detector / pedometer uses accelerometer and gyroscope to detect steps, determine step distances automatically, and compute other parameters from them. A good and reliable step detector is very important when determining patient activity, monitoring sport.
This algorithm was developed partly on X16C datalogger manufactured by Gulf Coast Data Concepts, tested on a representative annotated database achieving excellent result:
Sens = 99.6%
PPred = 99.9%
