INTELLIGENT ULTRASONIC DETECTION OF WALKING STICKS FOR THE BLIND

Abstract - Visually impaired individuals face significant challenges in navigating their surroundings independently and safely. This project presents the design and implementation of an intelligent walking stick equipped with ultrasonic sensors, a voice assistance module, and a water detection unit. The system is developed to provide real-time alerts to the user using vibrations and voice feedback when obstacles or wet surfaces are detected. Additionally, it incorporates a medicine reminder feature and an emergency alert mechanism through voice prompts, enhancing both daily usability and critical safety for the user. By integrating low-cost components like the Arduino UNO, APR33A3 voice module, and ESP8266 for wireless connectivity, the proposed system offers a reliable and affordable solution for aiding the visually impaired.
