A method for detecting the fall of an object includes: acquiring a plurality of time-varying accelerations associated with a movement of said object； computing a plurality of respective velocities and displacements in the direction of gravity, based on the plurality of time-varying accelerations； determining lead time and return time of the movement, based on the plurality of accelerations, velocities and displacements, wherein the lead time equals a time interval from an original point of the movement to an extreme point of the movement, and the return time equals a time interval from the extreme point of the movement to a final point of the movement； and determining whether the fall of said object occurs, based on whether a peak value of the velocities is larger than a predefined threshold value and whether the lead time is longer than the return time.
