Abstract
In a road guidance using a Braille block, it has not been possible to determine a walking direction of a user only by a single Braille block. To solve the above problem, in a road guidance system including a mobile information terminal and a Braille block, the mobile information terminal includes a photographing processing unit, a QR code analysis processing unit that analyzes a QR code, a voice output processing unit, and a control unit, a QR code is affixed to the Braille block, and the control unit analyzes the QR code affixed to the Braille block photographed by the photographing processing unit using the QR code analysis processing unit to obtain QR code information, generates road guidance information generated based on a walking direction of a user holding the mobile information terminal from the QR code information, and outputs the road guidance information from the voice output processing unit as a voice.
