A Low-Cost IoT based Navigation Assistance for Visually Impaired Person

The Smart Shoe is an adaptive technology that can significantly improve the accessibility and comfort of living for individuals who are visually impaired. The proposed system presents a promising solution to address the challenges faced by visually impaired individuals in daily life. This system aims to assist visually impaired individuals with mobility and navigation by designing a Smart Shoe that can detect obstacles in their path. The shoe utilizes IoT technology and incorporates various sensors such as Ultrasonic, IR, Gyroscopic, and Accelerometer, along with a Microcontroller (ESP32), battery, and vibration motor. The shoe also has a battery that powers the system, making it independent of any external power source. When an obstacle is detected, the shoe sends a warning signal via voice command and vibration to the user via app. The app includes automated voice commands, which are sent to wireless headphones when an obstacle is detected. This feature makes it easier for visually impaired individuals to navigate and move around more independently. The system is portable, lightweight, easy to use, and affordable. This technology improves the accessibility and comfort of living for visually impaired individuals, enabling them to move around more safely and independently.
