WEARABLE DEVICE TO GUIDE A HUMAN BEING WITH AT LEAST A PARTIAL VISUAL IMPAIRMENT CONDITION AROUND AN OBSTACLE DURING LOCOMOTION THEREOF

摘要

A wearable device includes a receiver circuit embedded within a dress accessory of a human being to receive a scattered component of a signal from a transmitter circuit, and a distance sensor circuit to sense distance between the human being and an obstacle responsible for the scattered component during locomotion of the human being. The human being is associated with at least partial visual impairment. The wearable device also includes a communication circuit embedded within the dress accessory or another dress accessory of the human being to communicate a varying distance between the human being and the obstacle through varying a time interval between communicative actions to be sensed by the human being. If the obstacle is determined to be a new static obstacle through a central server, data related to the obstacle is added to one or more database(s) associated with the central server.

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 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 blind 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; and adding 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.
