摘要

The present invention relates to a method for providing a route guidance service for visually impaired people, the method comprising the steps of: when a predetermined application is selected through a user input, transmitting a request for a route guidance service together with location information acquired through the GPS of a user terminal simultaneously with execution of the selected application; servicing, by a route guidance server, search path information corresponding to an input destination on the basis of the location information received from the user terminal according to the route guidance service request from the user terminal; broadcasting, by the user terminal, an inquiry signal through a Bluetooth device search request, identifying an earphone by a device which transmits a response signal to the broadcasted inquiry signal, and performing paging with the identified earphone; and recognizing a user's walking direction on the basis of the search path information through outputting a signal by gyro sensors attached to both sides of the earphone according to a user's movement, converting the recognized result into a guidance sound according to a route guidance service rule, and outputting the guidance sound to the earphone.
