1. A method of guiding a human being with one of:

  • an at least partial visual impairment condition and a temporarily induced at least partial visual impairment condition during locomotion thereof, comprising;

    embedding a receiver circuit within a dress accessory of the human being;

    receiving a scattered component of a signal from a transmitter circuit through the embedded receiver circuit, the scattered component resulting from scattering of the signal from the transmitter circuit by an obstacle;

    sensing data related to a distance between the human being and the obstacle during the locomotion of the human being through a distance sensor circuit communicatively coupled to the embedded receiver circuit in conjunction with a processor based on comparison between the scattered component and at least one of;

    threshold values and the signal from the transmitter circuit;

    embedding a communication circuit within one of;

    the dress accessory and another dress accessory of the human being;

    communicating, through the communication circuit, a varying distance between the human being and the obstacle through varying a time interval between communicative actions of the communication circuit configured to be sensed by the human being in order to enable the guidance during the locomotion thereof around the obstacle;

    determining, through a central server in conjunction with the processor, location information of the human being, the central server being communicatively coupled to the processor through a computer network;

    determining, through the central server in conjunction with the processor, that the obstacle is a new obstacle about which data is unavailable in at least one database associated with the central server based on the determined location information and predefined obstacle data stored in the at least one database corresponding to the determined location information;

    determining, through the central server in conjunction with the processor, that the obstacle is a static obstacle based on a time-invariant characteristic of the received scattered component of the signal, the time-invariant characteristic of the received scattered component of the signal being a power amplitude thereof for the determined location information of the human being;

    and interpreting, through a gesture interpretation circuit, a gesture from the human being to at least one of;

    trigger transmission of the signal from the transmitter circuit, and switch on at least one of;

    the receiver circuit and the distance sensor circuitadding data related to the obstacle to the at least one database associated with the central server following the determination thereof as the new obstacle and the static obstacle.
