Raspberry Pi Based Smart Navigation System for the Visually Challenged

Self-determination is the foundational mechanism for realising one's dreams and goals in life. Unsighted people are justified in going out on their own. There are millions of visually challenged persons in the globe who are always in need of assistance. They must rely entirely on others for every minor work, not only devices. To replace the aforementioned gaps in the lives of visually challenged people, we offered a gadget loaded with modern technology that would allow the individual to conduct their own job rather than rely on others. In this project, we will use a Raspberry Pi to create a navigation system for visually challenged people, the system would contain a pi cam module to detect the objects further that will be implanted with a moisture and ultrasonic sensor to detect real-time obstacles while walking and will be linked to the Google Maps cloud for optimal navigation. This will result in a smart system that will be incredibly beneficial for blind people while also being more precise and safe. Blind individuals use voice to engage with the system. Using 4G technology, the cloud platform communicates with the smart phone. The suggested system may give more plentiful surrounding information and more accurate navigation, as well as validate the system's practicability.
