From Turn-By-Turn Directions to Overview Information on the Way to Take

Abstract: This chapter examines the in-advance route directions that provide a coarse overview on the way to take. We discuss the required properties of these directions in order for them being useful and present some first methods to generate such instructions. These methods are based on the model for context-specific route directions as presented in Richter & Klippel (2005); cardinal directions, global landmarks, and environmental structure, like different districts, are used as elements in our approach to generate coarse directions that indicate major reorientation points along the way. The generation process results in an abstract relational specification of these directions that reflect conceptual elements of route information; the abstract specification may then be externalized in different modalities, for example verbally or graphically, to be presented to the user, which will be outlined.

An assisting, constrained 3D navigation technique for multiscale virtual 3D city models

Abstract: Virtual 3D city models serve as integration platforms for complex geospatial and georeferenced information and as medium for effective communication of spatial information. In order to explore these information spaces, navigation techniques for controlling the virtual camera are required to facilitate wayfinding and movement. However, navigation is not a trivial task and many available navigation techniques do not support users effectively and efficiently with their respective skills and tasks. In this article, we present an assisting, constrained navigation technique for multiscale virtual 3D city models that is based on three basic principles: users point to navigate, users are lead by suggestions, and the exploitation of semantic, multiscale, hierarchical structurings of city models. The technique particularly supports users with low navigation and virtual camera control skills but is also valuable for experienced users. It supports exploration, search, inspection, and presentation tasks, is easy to learn and use, supports orientation, is efficient, and yields effective view properties. In particular, the technique is suitable for interactive kiosks and mobile devices with a touch display and low computing resources and for use in mobile situations where users only have restricted resources for operating the application. We demonstrate the validity of the proposed navigation technique by presenting an implementation and evaluation results. The implementation is based on service-oriented architectures, standards, and image-based representations and allows exploring massive virtual 3D city models particularly on mobile devices with limited computing resources. Results of a user study comparing the proposed navigation technique with standard techniques suggest that the proposed technique provides the targeted properties, and that it is more advantageous to novice than to expert users.

Navigation apparatus, service apparatus of navigation apparatus and service provision method by navigation apparatus

Abstract: PROBLEM TO BE SOLVED: To provide a navigation apparatus, a service apparatus of the navigation apparatus and a service provision method by the navigation apparatus which are applied to a car navigation apparatus, eliminate a user burden and accurately offer information meaningful for a user. SOLUTION: A category of shops etc. corresponding to a user preference and a tendency corresponding to the user preference in the category are detected by referring to an icon configured on a map by the user. The information relating to the shops and/or facilities is selectively offered to the user based on a detected result. COPYRIGHT: (C)2004,JPO

Displaying Navigation Information Within a Secondary User Interface of a Mobile Device

Abstract: Computer-implemented methods and systems of displaying navigation information on a mobile device include determining navigation directions to a destination location and providing related navigation information for display on a primary user interface while the mobile device is operated in an active operating mode. Upon detecting a transition of the mobile device from the active operating mode to a passive operating mode, a subset of location information is configured for display on a secondary user interface. The passive location information can include one or more of a semantic place label associated with the mobile device's current location and a directions indicator in which a user of the mobile device should travel along the navigation directions in order to reach the destination location from the mobile device's current location and/or device orientation. The navigation information can be updated continuously, periodically and/or upon reaching turn points within the navigation directions.

Navigating the future

Abstract: A United States Department of Defense system called NAVSTAR Global Positioning System (GPS) is revolutionizing navigation and positioning technologies. GPS is a satellite-based, radio-navigation system consisting of 24 satellites arranged in 6 orbital planes at an altitude of 20,000 km and a ground-based infrastructure that monitors and controls the satellites. Every transportation mode can benefit from GPS. On the nation's highways, GPS can provide navigation and guidance to vehicles and buses, automated voice for bus stop annunciation, and accident data collection. The rail industry can track hazardous cargo and monitor the location of entire trains on their track network to prevent collision. The most dramatic use of GPS will eventually be in guiding an aircraft from the time it takes off until the time it lands. Finally, many marine navigators use a complex system of buoys, navigational beacons, and landmarks, which can be pinpointed accurately using GPS. This article describes how GPS works, the services available and the errors associated with services, the needs and requirements of users, augmentation services, and future developments. The author reports that the advances being made today are nothing short of phenomenal.
