Abstract

To address the travel safety needs of visually impaired individuals, this paper presents a smart blind guidance shoe based on Internet of Things (IoT) technology to enhance their travel safety and autonomy. The system uses the STM32 microcontroller as its core controller and realizes obstacle detection, road condition recognition, and positioning and navigation functions through multi-sensor fusion. It also enables real-time data transmission and remote monitoring through “Bluetooth 5.0 + NB-IoT” dual-mode communication, in combination with a cloud platform and a mobile phone APP. This research provides a technical reference for the intelligence of travel assistance devices for visually impaired people and expands the application scenarios of IoT technology in the field of assisting special groups in walking.
