Navigation system with animated intersection view

Abstract: A vehicle navigation system helps guide a driver to a destination by enhancing visualization of upcoming intersections. The navigation system stores animation data that depicts the intersection as it will appear to the driver. The animation data may be a sequence of images (e.g., digital camera images) taken at intervals before and after the intersection. The navigation system may show the images in synchronism with the progress of the vehicle to provide an animated display of the intersection for the driver. The animated display aids the driver with following a recommended navigation route to the destination.

Map matching method and apparatus for navigation system

Abstract: A map matching method and apparatus for a navigation system estimates a location of the navigation system on a correct road segment when a GPS signal is invalid. The map matching method creates a database of pairs of locations at which the navigation system encountered GPS signal loss and recovery in the first time. The navigation system conducts a map matching processing when the GPS signal is lost in the second time at the recorded location by incorporating various additional factors to match the current position with a correct road segment. The various additional factors, in addition to the measured data by a dead reckoning process, include road class, road accessibility, road angle, proximity to candidate road, etc.

Navigation and promotion distribution system

Abstract: A navigation and promotion system has a navigation module receptive of information relating to a current location of a user, a target destination, and location-dependent navigational options, wherein the navigation module is adapted to generate a navigational instruction based on the navigational options, the current location, and the target destination. A promotion module is receptive of information relating to user needs, promotional offers, and the target destination. The promotion module is adapted to select a promotional offer based on an inference of user interest, wherein the inference of user interest is based on the target destination. An output is adapted to communicate the navigational instruction and the selected promotional offer to the user.

Edge navigation user interface

Abstract: A user interface for a touch-screen display of a computing device is described. The user interface has an edge navigation feature designed to facilitate navigation through digital content items, such as electronic books, in response to user input received via the touch-screen display. This navigation may be to an arbitrary point within the content, or to previously defined bookmarks. The user interface provides a representation of a virtual edge of the content object, such as a book or album. Presentation of this virtual edge, overlaid with bookmark indicators, allows the user to spatially visualize the position of content within the book, and select a desired location or bookmark.

Modeling and verification of adaptive navigation in web applications

Abstract: The navigation of a web application is the possible sequences of web pages a user can visit. In the simplest case the next page is determined by the current page and the action (e.g. link, button) selected by the user. However, many web applications now incorporate adaptive navigation, where the next page also depends on the user's mode, for example whether they are a customer or an administrator, or depends on what pages the user has visited previously.Navigation models are useful for clarifying requirements and specifying implementation behavior. When a model is formal, it can also be used to generate design or implementation artifacts, and can be verified for properties such as broken links or length of navigation path. These uses are all important for the case of simple navigation, but even more important for adaptive navigation because of the added complexity. However, none of the current formal approaches can support adaptive navigation.In this paper we present an approach that uses Statecharts to formally model adaptive navigation, and show how important properties of a navigation model are verified using existing model-checking tools. We summarize the kinds of properties that can be checked with such a model, and describe how to use the Symbolic Model Verifier (SMV) tool to perform the verification. Finally, we use the Blockbuster® web site as a case study to demonstrate how our approach can uncover navigation problems that arise when new requirements are imposed.
