In our society, several supports are required for the physically disabled person. One of the supports is the guarantee of mobility for the blind and low-vision people. There are many efforts but even now, it is not so easy for the blind people to independently move anywhere. In this paper, a navigation scheme has been proposed and materialized for the blind and low-vision people in order to provide precise location information using Android-base smart phone with a view to move freely. The navigation scheme uses TTS (Text-to-Speech) for blindness in order to offer a navigation service through voice and Floyd-Warshall algorithm for suggesting the shortest paths. Also, it uses Google map API to show the route information. The proposed scheme, as an independent program, is fairly cheap and it is possible to install onto Android-based smart phone in an easy manner. This allows blind and low-vision people to access the program interactively. The performance of the application has been tested through Android 4.2.1 based Samsung Galaxy mobile phone. As the result the voice-support about the map information has advanced favorably. Download
