Abstract
Blind people need assistance in detecting obstacles, finding locations, and getting directions while moving around to reach their specified destination. Based on this persistent need, we suggest a navigation system to facilitate these requirements. We provided this navigation system to blind students, employees, or guests within King Saud University campus area. The technologies used in our proposed system are: the blind mobile device, RFID tags and Reader, GPS, text to speech, voice Recognition, and WiFi. The system detects the blind location using GPS, if internet connection is available, and uses RFID tags fixed outdoors and indoors on the building in the path, WiFi routers are used indoors to detect the location. The system uses voice recognition and text to speech to communicate with the blind to lead him to his destination and to give him the directions. The results show good performance in obstacles avoidance and in blind guidance.
