Accessible Menu Navigation Techniques For Electronic Devices

Abstract: Techniques are disclosed for providing an accessible menu navigation mode in electronic computing devices. The user can engage a manual reading mode, using a manual reading mode activation gesture, wherein the user may navigate through content, share content, or change reading rate, font, volume, or other device settings. The user may navigate through a menu structure using menu navigation gestures and the menu and sub-menu options may be read aloud to the user as they are navigated through. A selection gesture may allow the user to enable or adjust various menu and sub-menu options, and an earcon or sound effect may guide the navigation process and/or confirm a menu selection. The user may configure the navigation gestures and option selection gestures. The menu options may be structured to allow a user to access content navigation options with upward swipe gestures and access device settings using downward swipe gestures.

Comparative benefits of various automotive navigation and routing technologies

Abstract: The first practical in-vehicle automotive navigation systems utilized dead reckoning combined with digital map-matching to keep track of vehicle positions and to show them in real time on digital map displays. Global Positioning Satellites (GPS) and differential GPS have provided significant navigation system improvements when combined with dead-reckoning, and they have enabled alternative navigation systems that operate without dead reckoning. The introduction of map databases with accurate connectivity, directionality, and turn-restriction attributes have permitted automatic computation of optimum routes as well as presentation of turn-by-turn route-guidance instructions for driving those routes. This paper looks at advantages and limitations of various automobile location and routing techniques, and discusses how limitations can be overcome by combining techniques. Trade-offs between features, performance, and cost are also presented for some specific implementations.

Navigation system for electric vehicle and navigation service method thereof

Abstract: The present invention provides a navigation system for an electric vehicle and a navigation method for the same. The navigation system searches for the location of a charging station and paths where traveling of an electric vehicle is possible; provides the charging station location information and information of the searched paths to a navigation terminal, thereby improving usability and traveling stability of an electric vehicle, resulting in increased road efficiency.

A spatial cognitive map and a human-like memory model dedicated to pedestrian navigation in virtual urban environments

Abstract: Many articles dealing with agent navigation in an urban environment involve the use of various heuristics. Among them, one is prevalent: the search of the shortest path between two points. This strategy impairs the realism of the resulting behaviour. Indeed, psychological studies state that such a navigation behaviour is conditioned by the knowledge the subject has of its environment. Furthermore, the path a city dweller can follow may be influenced by many factors like his daily habits, or the path simplicity in term of minimum of direction changes. It appeared interesting to us to investigate how to mimic human navigation behavior with an autonomous agent. The solution we propose relies on an architecture based on a generic model of informed environment, a spatial cognitive map model merged with a human-like memory model, representing the agent's temporal knowledge of the environment, it gained along its experiences of navigation.

Address input method and apparatus for navigation system

Abstract: A method and apparatus for use with a navigation system allows a user to easily and quickly input an address of a destination with use of a specially made database even when spelling of the address is not certain to the user. The navigation system is designed to help the user in entering a desired street name accurately and efficiently by checking candidate cities when a first character of street name is specified. Since the user accurately knows at least the first character of the intended street name, the candidate street names will be narrowed down by selecting the city. The user may further input second character and further characters upon which the navigation system incrementally retrieves candidate street names with use of the comprehensive alphabetical usage file.
