Path Finder

Path Finder is a supportive navigation system created to help visually impaired individuals move more safely and confidently. Traditional tools, like white canes, often miss important details especially small obstacles on the ground or hazards at head level. This can lead to accidents and make navigating busy or unfamiliar places stressful. Path Finder addresses these challenges by using smart sensors and wireless communication to give users real-time awareness of their surroundings. The system is made up of two parts, Smart Footwear and Smart Eyewear. The Smart Footwear uses a VL53L0X Time-of-Flight sensor and an ESP32 microcontroller to detect steps, curbs, or uneven ground and send this information wirelessly. The Smart Eyewear, built with an ESP32-C3, warns the user about obstacles at head height. A small buzzer provides simple feedback the closer the obstacle, the faster or louder the sound. By working together, these two devices offer a practical, affordable solution that helps visually impaired users navigate more safely and independently.
