Strapdown Inertial Navigation Technology, Second Edition

Abstract: photographing -not to mention walking in the city -plus those of us engaged with defense activities can state it is more convenient to get lost if one knows where this happ ens. Perhaps this is one of the key reasons why methods and technologies for navigation have been an area of continuing efforts and interest. After the introduction of fast moving vehicles, and later when defensive or hostile weapons came into use, it was not sufficient to know where the platform was located but it was really vital to be aware of its momentary alignment, of course , in a three dimensional space. New challenges were put to the shoulders of the navigator. When time, equipment. and location allow, navigation rel ying on external references such as radio beacons on ground or up in the space orbits are often preferred. However, such cooperative systems may not be available, or their performance is inadequat e for the short time constants of platform motion. We are thus forced to use autonomous navigation modes. It is here that inertial navigation systems have.

Displaying a map having a close known location

Abstract: A system and method is provided for displaying a map having a close known location and a destination and for providing navigation recommendations for traveling from the close known location to the destination. A user may use a mobile device to submit a request for navigation instructions for navigating from a starting point to a destination. The request may be submitted to a web server, to the mobile device itself, or to another device that can provide navigation instructions. The web server/mobile device or other device determines a recommended route based on the starting point and the destination, and attempts to locate a close known location to the destination near the recommended route. Navigation instructions are provided to the user including directions from the close known location to the destination.

User interface system and method for a vehicle navigation device

3D navigation techniques

Abstract: A system and method is provided for facilitating navigation techniques in a three-dimensional virtual environment. The present invention couples input driving techniques to the state of one or more workspace variables (e.g., object state, virtual body state, environment state) to change the user's viewing context within a single input control motion. Modification of the user's viewing context allows navigation to various positions and orientations with out the need to be provided with that viewing context prior to navigation. The modification of the user's viewing context also allows for single input motion employing the same input drive controls.

Vehicle navigation system and methods for incorporating user preferences into same

Abstract: Traffic information, including traffic flow information and traffic incident information, obtained through a traffic management system for providing and facilitating the exchange of traffic information between a remote location and a vehicle may be presented to a user on a user display in the vehicle. The traffic information may be presented to the user in several circumstances, either as cued by the user, or automatically presented by the traffic management system. The present invention discloses a vehicle navigation system for providing personalized traffic information to a user of the vehicle navigation system and methods for the same. The personalized traffic information is based at least in part on user preferences, either manually input by the user or automated by the vehicle navigation system.

Turning the page on navigation

Abstract: In this paper, we discuss the findings of an in-depth observational study of reading and within-document navigation and add to these findings the results of a second analysis of how people read comparable digital materials on the screen, given limited navigational functionality. We chose periodicals as our initial foil since they represent a type of material that invites many different kinds of reading and strategies for navigation. Using multiple sources of evidence from the data, we first characterize readers' navigation strategies and specific practices as they make their way through the magazines. We then focus on two observed phenomena that occur when people read paper magazines, but are absent in their digital equivalents: the lightweight navigation that readers use unself-consciously when they are reading a particular article and the approximate navigation readers engage in when they flip multiple pages at a time. Because page-turning is so basic and seems deceptively simple, we dissect the turn of a page, and use it to illustrate the importance and invisibility of lightweight navigation. Finally, we explore the significance of our results for navigational interfaces to digital library materials

Unified navigation shell user interface

Abstract: A user interface for navigating among screens on a personal computer. The screens, which include layers of a shell user interface and various locations within applications, are presented as pages. In addition, commands and help information of an application are presented as a web of command pages. To this end, a unit of measure, called a “place” is defined. In general, an application is a place, and separate documents within an application may also define a place. Separate command windows and dialog boxes within an application or a document typically do not define a place. Backwards navigation takes the user to the previous place, and forward navigation (if possible) takes the user to the next place. Because the underlying data for a page may change between an initial visit to a page and navigation back to the page, data objects and page code are maintained separately, and are combined only when a request for a page is made.

The Effect of Vehicle Navigation Systems on the Formation of Cognitive Maps

Abstract: Vehicle navigation systems aim to support drivers in strategic - e.g., route choice - and tactical components of the overall driving task, and. as such, they provide a relatively novel means by which individuals acquire and use spatial information. There has been considerable interest from researchers and practitioners in the design and evaluation of user interface for vehicle navigation systems. This emphasis is to be expected given that this technology is arguably the most sophisticated with which drivers have had to interact with vehicles. A mediating factor critical to these issues concerns the extent to which drivers develop a cognitive map when using a vehicle navigating system. The level of such internal knowledge will inevitably affect dependency on an external source of navigation information. Although there have been numerous mentions on the importance of this issue, remarkably few empirical studies have been undertaken. Furthermore, existing studies have been limited in three key aspects: requiring drivers passively to watch videos of interconnected routes while listening to navigation decisions, rather than actively partaking in navigation tasks; artificially motivating participants to learn the area to which they are traveling, by continually testing cognitive map development; and utilizing indirect rather than direct measures of cognitive map development. This paper aims to provide some preliminary data related to the impact of vehicle navigation system use on the formation of drivers' cognitive maps.

Movable-body navigation information display method and movable-body navigation information display unit

Abstract: A movable-body navigation information display unit is provided. In the movable-body navigation information display unit, a driver can intuitively and accurately recognize a relation between navigation information and a real picture or a real landscape. In addition, it is possible to avoid a state that visibility of a caution-needed picture such as a pedestrian in the real picture and a real picture of a road construction site is inhibited by an image of the navigation information. An image data creating section (405) matches road shape data with a road shape model to estimate posture data. In addition, the image data creating section creates picture (image) data for accurately compositing and displaying the image of the navigation information in an appropriate position in a real picture (or in a real landscape) of a road ahead of a movable body, and displays the navigation information as a three-dimensional icon or the like. A picture display section (5) performs display based on the picture data.

Method and system for topological navigation of hierarchical data groups

Abstract: A system and method to visually navigate hierarchical data groups are provided. If a user wishes to graphically view network traffic data for a particular business group of network nodes, a network topology navigation tool may be provided to display to the user such information that is relevant to the selected business group and the corresponding hierarchy level. The user may also be permitted to access more detailed connection information through appropriate drill-downs.

Methods for displaying a route traveled by mobile users in a communication network

Abstract: An improved system and procedure for allowing a user to post a route to another mobile user or to himself. In one embodiment, a user in a vehicle (26a) engages his user interface (51) to record and transmit the traveled route to a second user in a second vehicle (26b) or to himself at a later time. The recipient receives the route in accordance with his user ID and other parameters specified or messages left by the initiating user. The route can be displayed on a map, in text, or audibly broadcast. In an alternative embodiment, the route can be left by a non-mobile user for the benefit of a mobile user using, for example, a home computer.

Adaptive navigation support with public displays

Abstract: In this paper, we describe a public navigation system which uses adaptive displays as directional signs. The displays are mounted to walls where they provide passersbys with directional information. Each sign is an autonomous, wirelessly networked digital displays connected to a central server. The signs are position-aware and able to adapt their display content in accordance with their current position. Advantages of such a navigation system include improved flexibility, dynamic adaptation and ease of setup and maintenance.

Smooth traffic flow with a cooperative car navigation system

Abstract: With maturation of ubiquitous computing technology, it has become feasible to design new systems to improve our urban life. In this paper, we introduce a new application for car navigation in a city. Every car navigation system in operation today has the current position of the vehicle, the destination, and the currently chosen route to the destination. If vehicles in a city could share this information, they could use traffic information to globally plan semi-optimal routes for each vehicle. Thus, we propose a cooperative car navigation system with route information sharing (RIS). In the RIS system, each vehicle transmits route information (current position, destination, and route to the destination) to a route information server, which estimates future traffic congestion using this information and feeds its estimate back to each vehicle. Each vehicle uses the estimation to re-plan their route. This cycle is then repeated. Our multiagent simulation confirmed the effectiveness of the proposed RIS system. The average travel time of drivers using the RIS system is substantially shorter than the time of drivers who chose shortest distance or simple shortest time estimates. Moreover, as the number of RIS users increases, the total amount of traffic congestion in the city decreases.

System and method for dynamic navigational route selection

Abstract: A navigation system and method factors into its routing decisions information pertaining to transient delays encountered from time to time, one example of such a transient delay is accident information obtained from currently available broadcast traffic flow sources. The system can also factor in historically available traffic delay data based on time of day or other parameters. The navigation system keeps track of the routes traveled by the vehicle (or user) and the times of transit of such routes. When a user requests a route based upon given end-points, the navigation system can use its own stored historical data, as well as currently available traffic delay data, to calculate and announce a given route.

Method and system for multiple route navigation

Abstract: Method and system for providing multiple route navigation guidance. The system comprises a client integrated with a mobile communication device (e.g. PDA, cellular telephone, etc.) and a server communicating via wireless carriers and networks. The server obtains a user's initial position, a user-designated destination, and calculates multiple routes from the user's initial position to the destination. The client displays turn-by-turn navigation instructions to the user using the multiple routes sent by the server. If the client detects a deviation from the multiple routes, the client sends a request for new multiple routes to the server. Then, the server recalculates new multiple routes from the user's current position to the destination and sends navigation information related to the new multiple routes to the client.

Multiple roots in navigation pane

Abstract: A method and system of creating and customizing multiple roots in a navigation pane are described. By selecting desired pages and adding them to the navigation pane, users may create multiple roots with which to navigate. A multiple roots navigation system permits the user to bypass irrelevant pages while reducing the amount of information presented in the navigation pane. The individual root nodes may further be customized to reflect ownership, importance or general aesthetic preferences. Using multiple roots, a user is not restricted to a single hierarchical display structure.

Navigation method and system for accurately estimating positions of street address numbers

Abstract: A navigation method and system determines a more accurate position of a street address number with use of building footprint information or latitude/longitude information of POI (point of interest), thereby accurately defining a position of a destination. When a user specifies a street address number as his destination, the navigation system retrieves the street segment that should include the location of the specified address number therein. The navigation system also checks the map data as to whether there is any building footprint data or POI position data associated with the street segment. The navigation system selects absolute locations on the street segment based on the building footprint data or the POI position data and determines the location of the specified address number by interpolating between two absolute locations.

The multi-modal navigation system may be embodied in integrated navigation devices, as stand-alone navigation systems on a variety of computing devices, as a navigation service on a computing device or as a Web service, and the like. The multi-modal navigation system includes route data for a plurality of transportation modes. Route data for the plurality of transportation modes may be integrated, may be separately available, or any combination thereof.

3-D human navigation system considering various transition preferences

Abstract: Walking is the most fundamental means of human transportation. Unlike travel by car, walking is not planar, but rather stereoscopic. We therefore developed a real navigation system for pedestrian point-to-point navigation. We propose herein a method of 3D pedestrian navigation, in which position detection is driven mainly by dead reckoning. The proposed method enables ubiquitous round-the-clock 3D positioning, even inside buildings or between tall buildings. In addition, pedestrian navigation is customized by changing the costs of the road network links. Finally, a positioning data accumulation system is implemented so that we can log tracks and easily incorporate new roads or attributes in the future.

Presenting Route Instructions on Mobile Devices: From Textual Directions to 3D Visualization

Abstract: Publisher Summary This chapter reviews several means of presenting route instructions to a mobile user. It highlights some general considerations for presentations on mobile devices and discusses the process of generating route instructions, presenting route instructions, and technical issues associated with presenting route information in 3D. To produce a presentation that is appropriate for the current situation, it is necessary to adapt it to situational factors such as the currently available resources or the quality of the available positional information. Especially, when generating a presentation on mobile devices, two types of resources are of special importance: (1) Technical resources including factors such as speed, bandwidth and screen resolution and (2) The cognitive resources of the user that impact the way that information should be presented to the user. In addition to cognitive and technical resources, the user's current position is not only a key factor in determining the kind of situation a mobile user is in but also highly relevant in the context of generating and presenting route instructions. For example, knowing the user's current location is vital if the beginning of a route corresponds to his/her current location, which frequently occurs in the case of a mobile user.

The rotating compass: a novel interaction technique for mobile navigation

Abstract: In current mobile navigation systems users receive the navigational instructions on a visual display or by descriptive audio. The mapping between the provided navigation information and the surrounding world has still to be performed by the users. In our approach that aims at public spaces, we combine a public display that shows directions with a synchronized output on a personal device. We describe a system where on the public display a compass with a rotating needle is shown. When the compass needle points in the desired direction, the mobile device of the user vibrates. This unobtrusive cue, allows the user to navigate without listening to or looking at the mobile device. In this paper we introduce the concept of synchronized information displays for navigation. We describe our prototype of such a system and report on a user study, that shows the feasibility of the approach.
