Navigation System For The Visually Impaired And Method Thereof

A navigation method for the visually impaired, comprising,

• providing a server, a plurality of traffic condition information transmission devices and at least one mobile device, wherein the server comprises an acquisition module, a processing module and a transmission module, and each of the plurality of traffic condition information transmission devices is disposed correspondingly to a road lamps, and the at least one mobile device comprises a receiving module, a navigation module and a speech module;
• acquiring, by the acquisition module, construction information through a network service and/or real-time traffic condition information through a traffic broadcasting service;
• classifying, by the processing module, the construction information and/or the real-time traffic condition information according to a geographic location corresponding to the construction information and/or the real-time traffic condition information, and transmitting, by the transmission module, the construction information and the real-time traffic condition information according to the geographic location corresponding to the construction information and the real-time traffic condition information;
• receiving, by each of the plurality of traffic condition information transmission devices, the construction information and/or the real-time traffic condition information corresponding to a location thereof, and forwarding the received construction information and/or the received real-time traffic condition information;
• planning, by the navigation module of the at least one mobile device, a navigation route according to a requirement of the visually impaired;
• linking the receiving module of the at least one mobile device to at least one of the plurality of traffic condition information transmission devices located on the navigation route, and receiving, by the receiving module of the at least one mobile device, the construction information and/or the real-time traffic condition information transmitted from the linked traffic condition information transmission device, so as to make the navigation module modify the navigation route according to the construction information and/or the real-time traffic condition information received by the receiving module;
• and
• converting, by the speech module, the construction information and/or the real-time traffic condition information into speech information for the visually impaired, and converting, by the speech module, the modified navigation route into a real-time speech guiding message for the visually impaired.
