Abstract: As numerous applications can be derived from the third generation mobile communication technology, this thesis is about the research on developing the navigation system for the blind by leveraging on 3G and GIS. Such a system enables direction givers at home to direct the blind, allowing them to travel alone. Moreover, the system can also be applied to many other fields. The realization technology of the system mainly integrates the third generation system communication, the geographic information system (GIS) and the global positioning system (GPS).
