Design and Development of a Smart Blind Stick for Enhanced Mobility and Independence of Visually Impaired Individuals

This study delves into the innovative design and development of a smart blind stick aimed at revolutionizing the mobility and independence of visually impaired individuals. Traditional white canes have long served as a primary aid for navigation, yet their limitations in detecting obstacles and providing real-time assistance underscore the necessity for a more advanced solution. The proposed smart blind stick integrates cutting-edge technologies such as ultrasonic sensors, artificial intelligence, fall detection and haptic feedback mechanisms to enhance the user’s spatial awareness and navigation experience. By leveraging ultrasonic sensors, the device accurately detects obstacles in the path and provide context-aware guidance. Furthermore, haptic feedback mechanisms deliver intuitive cues to the user, enabling them to distance their self from obstacles. When there is a sudden drop or falls, the accelerometer transmits data to GSM Module and send message notification to the user’s caretakers including the location. There is also an AI camera that allowed the caretaker’s to captured and view the surroundings of visually impaired through a mobile app. The design prioritizes user-centered principles, ensuring comfort, portability, and ease of use. Through rigorous development and iterative testing, the smart blind stick emerges as a promising tool to empower visually impaired individuals, fostering greater mobility, confidence, and independence in navigating their daily lives. The smart cane with overall user satisfaction of 4.11, proves the efficiency and effectiveness of it.
