For people with visual impairment, moving safely from one place to another is a daily challenge. Traditional walking sticks are helpful but limited, as they can only detect obstacles when they come into direct contact.
This often leads to unsafe situations, especially in crowded or unfamiliar environments. To overcome this issue, this paper presents a Smart Blind Stick that uses ultrasonic sensing along with IoT technology to improve navigation safety.
The system is built using an Arduino Uno, an ultrasonic sensor, and alert components such as a buzzer and vibration motor. It continuously checks for obstacles in front of the user and gives immediate feedback when something is detected within a certain distance.
This helps the user react quickly and avoid accidents.
In addition, the device can send information through the internet using a Wi-Fi module, allowing basic monitoring and emergency support. The overall design focuses on simplicity, affordability, and ease of use, making it suitable for real-life application and improving independence for visually impaired users
