Abstract
Visual impairment significantly affects the mobility and independence of millions of people worldwide. Individuals with visual disabilities often depend on traditional white canes or assistance from others for navigation. However, these conventional aids provide limited information about obstacles, environmental hazards, and path conditions. With the advancement of sensor technology and embedded systems, assistive devices can be designed to improve safety and independence for visually impaired individuals.
This paper presents the design and development of a Smart Blind Stick that assists visually impaired people in detecting obstacles and navigating safely. The proposed system integrates ultrasonic sensors, infrared sensors, and a water detection sensor to identify potential hazards such as objects, staircases, and wet surfaces on the path. When an obstacle is detected within a predefined range, the system alerts the user through an audio buzzer. A voltage regulator ensures stable power supply to all components, enhancing system reliability.
The proposed smart stick is designed to be low-cost, portable, energy-efficient, and easy to use. Experimental testing shows that the system effectively detects obstacles within a range of approximately 3–4 meters and provides immediate alerts to the user. The developed system offers a practical assistive solution that enhances mobility and safety for visually impaired individuals. Future improvements may include GPS tracking, voice assistance, and smartphone connectivity for enhanced functionality.
