TL;DR: In this article, a navigation device is configured to provide an initial route based on an origin location and a destination location, and traffic messages describing traffic events are received by the navigation device.
Abstract: Based on an origin location and a destination location, a navigation device is configured to provide an initial route. Traffic messages describing traffic events are received by the navigation device. Based on a location code in each of the traffic messages, the navigation device determines a traffic event delay if the location code corresponds to any remaining segment(s) of the initial route. If at least one of the traffic messages corresponds to any remaining segment(s) of the initial route, a travel delay is calculated based on one or more traffic event delays. The navigation device calculates a new route from the current location to the destination location, and, if a new travel time of the new route is less than a remaining travel time of the initial route from the current location to the destination location plus the travel delay, the navigation device outputs the new route.

26 Jul 2006TL;DR: In this paper, a user previews a first navigational route generated by a first route generator, such as those incorporated in a navigation-related website, and a variety of location markers corresponding to different points along the route are generated.
Abstract: A method for matching navigational routes that are generated by separate route generators and are used by vehicle navigation systems. According to one embodiment, a user previews a first navigational route generated by a first route generator, such as those incorporated in a navigation-related website. From this first navigational route, a variety of location markers corresponding to different points along the route are generated. The location markers are then sent to a second route generator used by a vehicle navigation system, so that it can generate a second navigational route that is similar to the first route. The second navigational route is then sent to a navigation unit located on the vehicle, so that the driver can be given directions that generally correspond to the first navigational route which they initially reviewed on the navigation-related website.

TL;DR: Direct input by the user is combined with data derived from the observation of the user's LOM-Modality (Location, Orientation, and Movement) to annotate geographical data, and suitable routes even in unknown territory can be calculated.
Abstract: Although much effort is spent in developing navigation systems for pedestrians, many users with special needs are mostly excluded due to a lack of appropriate geographical data such as landmarks, waypoints, or obstacles. Such data is necessary for computing suitable routes which might differ from being the shortest or fastest one. In this paper, the concept of multimodal annotation of geographical data for personalized navigation is described. Direct input by the user is combined with data derived from the observation of the user's LOM-Modality (Location, Orientation, and Movement) to annotate geographical data. Based on this data and data derived from other users of the same user group, suitable routes even in unknown territory can be calculated.

TL;DR: A navigation system that allows a user to easily glance ahead down a route to see points-of-interest (POI) such as businesses along future portions of a route is presented to the user via an appropriate display as mentioned in this paper.
Abstract: A navigation system that allows a user to easily glance ahead down a route to see points-of-interest (POI) such as businesses along future portions of a route. POIs within a short distance radius of a selected future exit or other future point along the user's route may be presented to the user via an appropriate display. The short distance radius may be defined by constraints associated with the display (e.g., within a represented distance from the exit that can be shown in a current zoom level of the display). Instead of abandoning a navigation session, use of glance ahead instead suspends navigation while the user views snapshots of points-of-interest at each exit. The navigation system may show branded icons or business details associated with displayed POIs, preferably without the need for the user to access a separate screen.

TL;DR: The hypothesis is that images presented to the user in rapid succession can significantly enhance the previewing step, thus optimizing the selection step and improving navigability.
Abstract: In this paper we consider the role of rapid-fire presentation of images in the service of navigation in information spaces. We presume a model of information navigation in which the user performs a cycle of (pre)viewing, selecting, and moving. Our hypothesis is that images presented to the user in rapid succession can significantly enhance the previewing step, thus optimizing the selection step and improving navigability. We discuss two prototypes for navigation tools in Web information spaces in which images are used as the primary means for presenting meta-information about "upcoming" Web pages. The presentation is modeled as a flow of information streaming to the user, and orientation is visualized through positions in ordered sequences.
