Abstract
A person's exercise monitored using an accelerometer to detect and count the steps of the person. Furthermore, acceleration profiling distinguishes walking from running and total distance covered in the exercise is estimated using different stride lengths for walking and running. The person's pace may be maintained using a music playback unit with an adjustable rate of playback to influence the pace of the person with the music tempo.
