• a smart device communicatively connected to the wearable device for receiving the user exercise data and configured to play a course video through a display,
• wherein the smart device is configured to perform a plurality of steps or transmit the user exercise data and coach exercise data corresponding to the coach video to a computation module for performing the steps comprising:
• obtaining a coach window from coach exercise data, obtaining a user window from the user exercise data, wherein a length of the user window is longer than that of the coach window;
• searching a user segment from the user window that is most similar to the coach window;
• for a first exercise type, calculating an exercise score according to stabilities of the user segment and the coach window;
• and
• for a second exercise type, calculating the exercise score based on a difference between the user segment and the coach window by a deduction mechanism.
