In the prior art, in providing road guidance using tactile paving, it was impossible for a user to determine the direction to walk in from a single tactile paving block. In order to solve the aforementioned problem, this road guidance system comprising a mobile information terminal and tactile paving, wherein the mobile information terminal has an imaging unit, a QR code analyzer which analyzes QR codes, a voice output unit and a control unit, the tactile paving blocks each have a QR code affixed thereto, the control unit acquires QR code information by analyzing, by means of the QR code analyzer, a QR code affixed to a tactile paving block captured by the imaging unit, road guidance information generated on the basis of the walking direction of the user holding the mobile information terminal from QR code information is generated, and road guidance information is voice output from the voice output unit.

    在现有技术中,在利用盲道砖进行道路指引时,无法仅基于单个盲道砖判断用户的步行方向。为解决该问题,本发明提供一种包括便携式信息终端和盲道砖的道路指引系统,其中,便携式信息终端包括拍摄处理部、对QR码进行分析的QR码分析处理部、声音输出处理部和控制部,盲道砖上粘贴有QR码,控制部利用QR码分析处理部对拍摄处理部拍摄到的粘贴在盲道砖上的QR码进行分析来获得QR码信息,根据该QR码信息,生成基于持有便携式信息终端的用户的步行方向而得到的道路指引信息,从声音输出处理部通过声音输出道路指引信息。
