PURPOSE: A walk navigation system for the blind is provided to guide the walking direction with vibrational patterns of a long and short-termed vibration of a vibration motor, thereby accurately providing a walk guide regardless of a gripped portion and a gripped direction of a handle. CONSTITUTION: A walk navigation system for the blind comprises a stick(100), a control server(200), a first navigation relay server(310), and a second navigation relay server(320). The stick is composed of a support, a handle, a transceiving module(130), and a sound recognition module(140). The control server is wireless-communicated with the stick, thereby receiving walk input information including sound command and generating walk route data corresponding to the sound command. The first navigation relay server is connected to the control server, thereby receiving the walk route data and transmitting the guide data to the transceiving module within a first wavelength range based on the same. The second navigation relay server is arranged to be spaced from the first navigation relay server in order to have a second wavelength range.
