Virtual Booth

The Smart Blind Stick is an assistive device designed to help visually impaired individuals navigate safely and independently. Built using an Arduino and an ultrasonic sensor, the stick detects obstacles ahead by measuring distance, similar to how bats use echolocation. When an object is nearby, a buzzer produces warning sounds to alert the user and help prevent collisions or injuries. The system also includes a Bluetooth module that connects to a mobile phone through a serial Bluetooth application. It sends warning messages such as “Obstacle Detected” and “Obstacle Very Close.” This project supports SDG 3: Good Health and Well-being and SDG 10: Reduced Inequalities by improving mobility, safety, and accessibility for visually impaired individuals.
