EchoStride is a low-cost smart walking stick designed to enhance the safety and mobility of individuals with visual impairments. The system integrates an ultrasonic sensor with an Arduino Uno microcontroller to detect obstacles in the user’s path. When an object is detected within a predefined distance, the device activates two alert mechanisms: a buzzer that provides an audible warning and a servo motor that delivers vibration feedback at the handle. This dual-alert system improves user awareness and response time, enabling safer navigation in various environments such as schools, homes, hospitals, and public spaces.

The main objectives of EchoStride are to develop an affordable assistive device, improve mobility safety, and promote independence among visually impaired users. The product emphasizes simplicity, accessibility, and cost-effectiveness by using readily available electronic components. Unlike conventional smart sticks that rely solely on sound alerts, EchoStride combines both sound and vibration feedback, offering a more effective and inclusive warning system.

Aligned with several Sustainable Development Goals (SDGs), including Good Health and Well-being, Quality Education, Reduced Inequalities, Industry Innovation, and Sustainable Cities, EchoStride demonstrates the potential of simple engineering solutions to address real-world social challenges. Overall, EchoStride presents a practical and innovative approach to improving the quality of life for visually impaired individuals while promoting inclusive and sustainable technology development.
