IoT-BLE Based Indoor Navigation for Visually Impaired People

Indoor navigation and location searches for visually impaired people are challenging due to their nature. The proposed system uses Internet of Things (IoT) technology to give real-time location and navigation aids to blind people. GPS-based systems fail in indoor, making navigation difficult for blind people. Bluetooth Low Energy (BLE) is used to identify the network of smart devices for real-time location and navigation. This system provides IoT infrastructure to deliver real-time aural feedback, turn-by-turn instructions, and customized user-friendly navigation. The technology provides real-time navigation and location-based services to improve the experience. Auditory and tactile signals include room names, neighboring features, and emergency exits. Scalability and versatility make the platform appropriate for indoor positions such as retail malls, airports, and schools.
