This paper presents the architecture as well as the implementation of the system that helps the visually impaired person to navigate autonomously in the indoor environment. This method utilizes the Global Positioning System (GPS) and it also incorporates object avoidance technologies. The system applies a zigbee protocol to provide the continuous tracking of the visually impaired person. It also consists of additional components like ATMEGA microcontroller, ultrasonic sensor and microphone to provide more refined location and orientation information. The visually impaired person issues the command and receives the direction response using audio signals. The latitude and longitude values are received continuously from the GPS receiver and then transferred to the PC using the zigbee transceivers, using these values the localization of the visually impaired person is attained using Google map.
