1. A fall detection system for detecting a user's fall within an activity space, the fall detection system comprising:
a plurality of sensing devices each of which is disposed on a sensing position of a shoe of the user, each of the sensing devices comprising:
a ranging device configured to measure a distance between the sensing position and an ambient object, thereby obtaining a set of distance measurement data; and
a communication device configured to transmit the set of distance measurement data;
a data server configured to receive the set of distance measurement data of each of the sensing devices and perform a fall detection operation to determine if the user falls down according to the set of distance measurement data, wherein the data server issues a fall detection signal when it is determined that the user falls down; and
a display device configured to receive the fall detection signal and display a warning message in accordance with the fall detection signal.
