The project is built for the visually impaired and blind individuals and to help them in their daily lives and to avoid obstacles using special detection sensors. This system uses a Raspberry pi board (microcontroller) as the core of the navigation system. The system uses various inputs it receives from the ultrasonic sensor, the infrared sensor, camera and microphone. The data and signals received from the various input devices is processed by the Raspberry board. A GPS module is also connected to the system so that the user’s current location can be tracked for safety purposes. The data from the GPS module is processed with the help of a GIS system, which sends the processed information to an image processing system, which with the help of the Google speech API. All the processed information is passed to the Raspberry board which processes it produces the audio output via headphones. The main purpose of the paper is to gather contextual information to aid the blind or visually impaired user and to lend them a helping hand in their daily lives.
