The device is equipped with advanced functionalities, including GPS tracking for real-time location monitoring, MobileNet-based object and face recognition, OCR capabilities for reading printed text, and ultrasonic sensors for detecting obstacles, which trigger an alarm to alert the user. Its design prioritizes energy efficiency, allowing it to run effectively on low power while offering reliable real-time processing. By combining multiple assistive features into a single, cost-effective, and portable device, this solution sets itself apart from traditional options that often focus on one functionality or rely on expensive hardware. The modular and scalable architecture not only makes it an affordable and practical solution but also allows for easy customization and potential wireless enhancements. This flexibility opens up possibilities for broader applications in fields like assistive healthcare, autonomous navigation, and consumer electronics, making it a pioneering tool in inclusive technology that enhances mobility, security, and overall independence for its users.
