Claim 3:
4. 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 in accordance with a waveform feature of the set of distance measurement data of each of the sensing devices 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;
wherein a first one of the sensing devices is disposed on a toe of the shoe of the user, and a second one of the sensing devices is disposed on a heel of the shoe of the user.
