Method and system for providing walking instructions with route guidance in a navigation program

Abstract: A system and method are disclosed that provide an end user of a navigation program with information about walking to a desired destination in combination with information about driving to or close to the desired destination. In addition to the calculation of a route for driving to the desired destination, the navigation program uses data in a geographic database to calculate one or more routes to reach the desired destination by walking from locations within a walking threshold around the desired destination. In calculating these one or more walking routes, the navigation program uses the data in the geographic database to assess the suitability of roads around the desired destination for pedestrian travel. In calculating these one or more walking routes, the navigation program can also include road segments in the walking routes without regard for travel restrictions that only apply to vehicular traffic. Additionally, if the navigation program is installed in a vehicle, the navigation program may indicate the walking distance to the desired destination along one of the calculated walking routes as the vehicle approaches the desired destination. Additionally, the navigation program may provide the end user with walking directions to walk to the desired destination along one of the calculated walking routes.

A hybrid indoor navigation system

Abstract: We describe a hybrid building navigation system consisting of stationary information booths and a mobile communication infrastructure feeding small portable devices. The graphical presentations for both the booths and the mobile devices are generated from a common source and for the common task of way finding, but they use different techniques to convey possibly different subsets of the relevant information. The form of the presentations is depending on technical limitations of the output media, accuracy of location information, and cognitive restrictions of the user. We analyze what information needs to be conveyed, how limited resources influence the presentation of this information, and argue, that by generating all different presentations in a common framework, a consistent appearance across devices can be achieved and that the different device classes can complement each other in facilitating the navigation task.

Mobile terminal and a server for navigation system

Abstract: A navigation system in which a mobile terminal side 101 is not equipped with a CD-ROM for storing map database 105 , but implements an on-demand navigation function by sharing the one provided within a server 102 . By limiting the communications between the mobile terminal 101 and the server 102 only to the beginning of the route guidance and the moment at which the mobile terminal has deviated from the route, the communication traffic can be reduced, minimizing thereby the communication cost and the total power consumption as a whole, and further even when the mobile terminal 101 has deviated from the guide route, the system can readily provide the user with information by which he can reach his destination through communications with the server, and enabling also an indication of the name of the road to be taken at every crossings.
