| Summary: | Visually Impaired person faces day to day challenges due to the lack of sight. One of the
difficulties faced come to indoor navigation. Without any guidance, the visually impaired can
easily get lost. Even with the advancement in technology, there is a lacking of systems to help
visually impaired with navigation.
This report presents the implementation of an Indoor Navigation System for the Visually
Impaired using Bluetooth Low Energy (BLE) Technology. The system uses multiple BLE
beacons to perform trilateration to location the user indoor. Through an Android Application,
it communicates with the beacons and provides indoor audio-guided navigation. Additionally,
the system uses Object Detection Algorithm to alert the user of obstacles ahead.
