Description

Visually impaired navigation aids

This creation relates to a visually impaired navigation aid, especially a method that can not only make the overall structure design easier and more convenient, but also help users immediately guide when the position of the user's walking movement is deviated. It is an innovative designer of visually impaired navigation aids that prevents users from walking in the wrong direction of walking, making them more accurate in use, and adding practical features to their overall implementation and use.

According to the visually impaired people, there are many inconveniences in the action process due to visual obstacles. Thanks to the advancement of technology today, many related industries are committed to developing various types of visually impaired mobility aids for the visually impaired. It is more convenient to engage in various activities and help the home of the visually impaired to be more convenient.

Among them, please refer to the bulletin No. 5017559 "Analysis and Navigation System for the Action of the Blind" published on October 1, 2015. It includes: a hand-held mobile communication device, which is used to communicate with an Internet; a mobile recorder , Which includes at least a photography unit, which is used to record a road condition image; a reminder module, which includes at least one of a voice unit or a vibration unit, and issues a voice or Vibration alert; a Bluetooth, which communicates the handheld mobile communication device with the mobile recorder, and communicates the handheld mobile communication device with the reminder module; a database group including at least a route database and a traffic image Database, the route database includes information of a new route and at least one old route, the road condition image database includes at least one road condition classification image; a navigation module is stored in the handheld mobile communication device, and the Internet The network obtains a satellite positioning address of the handheld mobile communication device, and compares the satellite positioning address to Located on the new route or one of the old routes, and when the satellite positioning address is not on the new route or one of the old routes, a route alert is issued to the prompt module; an analysis module , Is stored in the handheld mobile communication device, and includes a route analysis and a traffic condition analysis, the route analysis is for selecting the new route or one of the old routes, and when the new route is selected, The Internet obtains the new route and saves the route database. The road condition analysis compares whether the road condition image matches the road condition classification image, and sends a road condition warning to the prompt module when the road condition matches. The warning is classified according to the corresponding road conditions. The process of the road condition analysis is as follows: the camera unit records the road condition image; Bluetooth returns the image to the road condition analysis; the road condition analysis obtains the analysis and comparison reference image from the road condition image database; compares a certain condition ; Road condition analysis sends a road condition instruction to the prompt module via Bluetooth; the prompt module notifies the user by voice or vibration.
