Abstract: A method for correcting life patterns for providing feedback for an exercise program periodically or in real time is disclosed. The method of the present invention detects a starting point of a dynamic activity interval periodically or in real time by sensing movement of a user in daily life, and provides an exercise program for filling a deficient amount of activity compared to a target value in the detected activity interval when the starting point is detected. Therefore, the method of the present invention may simply provide feedback for an amount of activity of a pertinent interval at an actual starting point of the dynamic activity interval, and thus the user may effectively follow the provided exercise program for correcting life patterns.
