Route guidance providing method for e.g. church, involves outputting route instruction in position dependent manner, monitoring authentication of instruction by user, and outputting instruction until instruction reaches destination

摘要

The method involves selecting a special operating state against worst quality of Global positioning system signals. A user is signalized in the special operating state, and a route instruction is output in a position dependent manner. Authentication of the involved route instruction is monitored by the user, and the route instruction is output until the instruction reaches destination. The special operating state is acoustically signalized based on the route instruction in a differential way.
