Abstract
The disclosed apparatus may include at least one radar device that transmits a frequency-modulated radar signal to a plurality of transponders located on a wearable device worn by a user. The apparatus may also include a processing device that (1) directs at least one of the plurality of transponders to be in an active state that enables the transponder to receive and transmit signals, (2) detects, while the transponder is in the active state, a signal returned to the radar device from the transponder in response to the frequency-modulated radar signal, (3) calculates, based at least in part on the returned signal, a distance between the transponder and the radar device, and (4) determines, based at least in part on the distance between the transponder and the radar device, a current physical location of at least a portion of the user. Various other apparatuses, systems, and methods are also disclosed.
