Pedestrian navigation aids: information requirements and design implications

Abstract: Recent years have seen an increased interest in navigational services for pedestrians. To ensure that these services are successful, it is necessary to understand the information requirements of pedestrians when navigating, and in particular, what information they need and how it is used. A requirements study was undertaken to identify these information requirements within an urban navigation context. Results show that landmarks were by far the most predominant navigation cue, that distance information and street names were infrequently used, and that information is used to enable navigation decisions, but also to enhance the pedestrian’s confidence and trust. The implications for the design of pedestrian navigation aids are highlighted.

Transmission of special routes to a navigation device

Abstract: A vehicle navigation system includes an adaptive routing module (210) that allows a user to provide inputs that influence routes that are calculated to predetermined destinations. A route calculation module (204) executed by a navigation server (102) is operable to calculate a first route from the trip origin to the trip destination. An adaptive route calculation (204) executed by the navigation server (102) is operable to allow the user to enter a user modification of the first route. After the user modification is entered by the user, a second route to the trip destination is calculated as a function of the user modification. The second route is then transmitted to a vehicle navigation system (104).

Vehicle navigation point of interest

Abstract: The present invention provides a navigation system for assisting locating points of interest during vehicle navigation. The system includes a processor enabled by software to receive and store a user selection of preferred visitation points and a user selected time and to determine and indicate a subset of the preferred visitation points that are located within a predetermined location relative to the vehicle position at the user selected time or relative to a selected destination.

Methods, systems, and devices for location specific alerts

Abstract: Methods, systems, and devices for location specific alerts. The method can include determining one or more positions using a navigation device. One or more weather signals received on at least a first channel of the navigation device, where the one or more weather signals include location information, can be compared to the one or more positions. From the comparison, a weather alert can be generated in the navigation device. Determining the one or more positions further includes determining the positions from a global positioning system (GPS) enabled navigation device.

Communication type navigation system and navigation method

Abstract: A communication type navigation system representing information for helping a user to select a route when selecting a leading path from a plurality of advised routes searched. According to a route search request from a navigation terminal (60), a navigation information providing server (10) performs route search and selects a plurality of advised routes. Moreover, evaluation information is created for the plurality of advised routes selected by using information (traffic information, meteorological information, facility information, user profile information) managed/held by the navigation information providing server (10). The valuation information is referenced by the user of the navigation terminal (60) so that the user can select a desired advised route from the plurality of advised routes.

Display method and apparatus for navigation system

Abstract: A display method and apparatus for a navigation system which is capable of easily and quickly showing the existence of a large structure within which a specific point of interest (“POI”) is located. The navigation system searches a desired point of interest as specified by a user, examines whether the point of interest is located within a large structure, searches an icon representing a type of the large compound in which the point of interest is located, and displays the icon of the large structure and the POI name on a monitor of the navigation system. Upon selection of the icon by the user, the navigation system displays detailed information on the large structure.

Hands-free, speech-based navigation during dictation: difficulties, consequences, and solutions

Abstract: Speech recognition technology continues to improve, but users still experience significant difficulty using the software to create and edit documents. In fact, a recent study confirmed that users spent 66% of their time on correction activities and only 33% on dictation. Of particular interest is the fact that one third of the users' time was spent simply navigating from one location to another. In this article, we investigate the efficacy of hands-free, speech-based navigation in the context of dictation-oriented activities. We provide detailed data regarding failure rates, reasons for failures, and the consequences of these failures. Our results confirm that direction-oriented navigation (e.g., Move up two lines) is less effective than target-oriented navigation (e.g. Select target). We identify the three most common reasons behind the failure of speech-based navigation commands: recognition errors, issuing of invalid commands, and pausing in the middle of issuing a command. We also document the consequences of failed speech-based navigation commands. As a result of this analysis, we identify changes that will reduce failure rates and lessen the consequences of some remaining failures. We also propose a more substantial set of changes to simplify direction-based navigation and enhance the target-based navigation. The efficacy of this final set of recommendations must be evaluated through future empirical studies.

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.

M3I in a pedestrian navigation & exploration system

Abstract: In this paper, we describe a near-complete Pocket PC implementation of a Mobile Multi-Modal Interaction (M3I) platform for pedestrian navigation. The platform is designed to easily support indoor and outdoor navigation tasks, and uses the combination of several modalities for presentation output and user input. Whereas 2D/3D-graphics and synthesized speech are used to present useful information on routes and places, fused input from embedded speech and gesture recognition engines allow for situated user interaction.

Technique for suggesting favorites in navigation

Abstract: In a navigation device, user profiles may be stored and used to navigate a user who may be driving in a vehicle, on foot, or in other mode of transportation. Each user profile corresponds to one of the user's personae. For example, the user business profile corresponding to the user's business persona may be different from the user personal profile corresponding to the user's personal persona. For instance, the user business profile may include fine-dining type restaurants for business meetings while the user personal profile may instead include fast-food type restaurants for personal dining. The navigation device provides the user with a navigated route, together with information concerning the favorite facilities and events surrounding the navigated route, which satisfy the preferences in a selected user profile. In addition, blockages may also be established using the device to avoid selected areas, e.g., high crime rate areas, in the navigated route, or to block transmission of selected information concerning, e.g., uninteresting facilities and events, to the navigation device.

Pervasive information acquisition for mobile AR-navigation systems

Abstract: Today car-navigation systems are increasingly penetrating the automotive market. However, the need for location-based information systems is no longer limited to cars. Mobile outdoor navigation systems for pedestrians and electronic tourist guides are already available on PDAs. In addition, new indoor positioning technologies extend the area of application for location-based systems. Unfortunately, current navigation systems are burdened by the fact that they are bound to a specific tracking technology (e.g., a car navigation system works exclusively with GPS) and therefore cannot be employed in areas with alternative tracking equipment. Furthermore, the information is provided through an abstract metaphor that the user has to understand and translate into action. We present a new augmented-reality-based paradigm and a framework for mobile navigation systems that pervasively extracts position and orientation information from any sensory source and enhances the association to the real world by combining video techniques and 3D-graphics in an augmented reality view.

The information received from the user device includes updated map information, traffic information, news information, weather information, event-related information, business-related information, and user-specified information. The navigation device performs route following based on commands received from the user device and transmits routing instructions to the user device. The navigation device and user device are separately operable by a user.

Extracting landmarks for car navigation systems using existing gis databases and laser scanning

Abstract: Today’s car navigation systems provide driving instructions in the form of maps, pictograms, and spoken language. However, they are so far not able to support landmark-based navigation, which is the most natural navigation concept for humans and which also plays an important role for upcoming personal navigation systems. In order to provide such a navigation, the first step is to identify appropriate landmarks – a task that seems to be rather easy at first sight but turns out to be quite pretentious considering the challenge to deliver such information for databases covering huge areas of Europe, Northern America and Japan. In this paper, we show approaches to extract landmarks from existing GIS databases. Since these databases in general do not contain information on building heights and visibility, we show how this can be derived from laser scanning data.

Navigation system allowing to remove selected items from route for recalculating new route to destination

Abstract: A method for navigation system modifies a route to the destination by allowing a user to select a type of items or conditions to be avoided from the route. The method includes the steps of displaying a set of data indicating items that a user will encounter when the user follows the calculated route, prompting the user to select a type of the item to be avoided in a new route to the destination, and recalculating the new route according to the user's selection and guiding the user to the destination through the new route. The navigation system that allows the user to freely choose settings for retrieving data or recalculate the route to the destination when the user selects to avoid or omit a particular type of traffic maneuver, traffic incident, or points of interest.

Navigation system, and program and storage medium for use in the same

Abstract: A navigation system that searches for a route to a destination based on stored map data and provides navigation guidance to the destination along the route includes a controller that acquires road congestion information associated with the route, searches for the route to the destination based on a calculated search cost and changes a search cost based on predicted secondary congestion that is predicted based on acquired road congestion information, wherein a recommendable route that can avoid congestion is searched based on the search cost that has been changed based on the predicted secondary congestion.

Enhanced Situation Awareness in Sea, Air and Land Environments

Abstract: Summary United States (US) military Special Forces teams currently use 2D visual displays for navigation information in the air, in water, and on the ground These current displays demand the user’s visual attention, which can compromise mission effectiveness, and using visual displays in low light visibility environments can cause fatigue, degrade performance, and compromise a clandestine situation If navigation equipment that is dependent on visual displays were integrated with a tactile display, the need to use vision for navigation could be minimized The operator could be more effective if his eyes were used to survey the surroundings rather than continuously monitor a visual display The Tactile Situation Awareness System for Special Forces (TSAS-SF) was developed to investigate the potential of tactile displays for Special Forces operations The TSAS-SF will upgrade present 2D visual navigation displays and will provide non-visual, non-audible navigation information to Special Forces personnel by interfacing navigation information with a tactile display This new capability will provide 2D direction cues to the skin, which will free the user’s visual senses for higher priority tasks (eg contact identification and classification) Preliminary testing in a High Altitude, High Opening (HAHO) parachute environment and a ground environment, and earlier testing in an underwater environment (McTrusty, Walters, 1997, Rupert, McTrusty, Peak, 1999), have demonstrated that navigation can be performed faster with tactile cues than visual cues, and superior navigational accuracy can be achieved with less mental fatigue on the operator These results suggest that a tactile display that provides ‘eyes free’ and ‘hands free’ air and ground navigation information may provide the opportunity to devote more time to other instruments and tasks when operating in high workload conditions These effects can increase mission effectiveness The preliminary results from the air and ground navigation tests justify continued testing and evaluation to extend the capabilities of the tactile display, for use as an operational device for navigation in sea, air and land environments

Vehicle navigation and safety systems

Abstract: A vehicle navigation system for alerting a vehicle driver of the presence and status of traffic devices. The vehicle navigation system may alert a driver of the time remaining before a traffic device, such as a traffic light, changes the flow of traffic. The vehicle navigation system may also alert a vehicle driver of traffic devices, such as stop signs and speed limit signs, when the driver is approaching the traffic device. The vehicle navigation system may alert a driver through audible or visual alerts, or both. The vehicle navigation system may include a display screen that may or may not be attached to a vehicle. The vehicle navigation system may also include an in-vehicle alert system enabling vehicle drivers to send alert messages to other vehicle drivers within a close proximity.

Unifying navigation model

Abstract: Systems and techniques to provide a unifying navigation model with a navigation service that provides an interface to information sources. In general, in one implementation, the technique includes: uniting navigation hierarchies from different application sources, and providing a unified navigation area based on the united navigation hierarchy. Uniting the navigation hierarchies can involve supplying a navigation service with a navigation object model that provides, to a presentation layer, a homogeneous view of navigation information from the different application sources. Providing the unified navigation area can involve displaying a navigation window in a portal presentation, the navigation window including navigation links to resources of the different application sources, and the navigation links being organized according to the united navigation hierarchy.

Balancing search and retrieval in hypertext: context-specific trade-offs in navigational tool use

Abstract: We compare user navigation performance using two hypertext information sites of identical node structure but embedded in different metaphors. The first is based upon the layout of a house and is consistent with Euclidean space. The second represents social links between people for which a spatial metaphor is not apparent. Search for targets within the structures, and the speed of their subsequent retrieval on a second search, is compared in a 2 × 4 × 2 factorial design manipulating: metaphor (spatial or non-spatial); navigation, tools (participants have both a site map and bookmark tool, one of these, or no tools at all) and the time pressure under which navigation is carried out (paced or unpaced). A strong main effect is found in which the spatial metaphor produces higher performance under all conditions. Similarly, time pressure has the general effect of trading-off a faster initial search with less efficient retrieval later. However, navigation tool use is highly context dependent and sometimes counterintuitive: certain conditions show poorer performance with two navigation aids than one. We argue that navigation tools are mediating structures for activities, such as bookmarking and learning the structure of the site, which represent cognitive investment for future retrieval. In this view, user performance is optimized by the balance of two potentially antagonistic conditions. First, the usability of tools and metaphor must free cognitive resources for planning; but also, the difficulty of the task and the need for planning must remain visible to the user. The implications for design are discussed.

WebScout: support for revisitation of Web pages within a navigation session

Abstract: WebScout is a system that creates a personal archive of Web pages seen by the user and a rich record of the user's navigation, including various types of user and system generated annotations. We explore how this rich archive can be used to provide support for user navigation, in particular, for revisitation of pages within a navigation session. We describe the WebScout SessionNavigator feature that enhances the current browser functionality by providing both sequential and graph representation of the user navigation. It introduces the concept of a WebTrail which designates a sequence of navigation steps, started by a particular event, such as search, or explicit specification of a URL by typing into the address bar, or executing a link from a bookmark list. We present details of a user study that explores how users perceive and remember their navigation on the Web.

The navigation information acquisition unit acquires navigation information relating to movement of the movable body. The requirement judgment unit judges as whether or not dialog start requirements are satisfied on the basis of the navigation information. The control unit gives a speech to a user to start providing interactive information, in case where the dialog start requirements are satisfied.

Robot navigation in corridor environments using a sketch floor map

Abstract: This paper presents a new robot navigation system that can operate on a sketch floor map provided by a user. This sketch map is similar to floor plans as shown at the entrance of buildings, which does not contain accurate metric information and details such as obstacles. The system enables a user to give navigational instructions to a robot by interactively providing a floor map and pointing out goal positions on the map. Since metric information is unavailable, navigation is done using an augmented topological map which described the structure of the corridors extracted from a given floor map. Multiple hypotheses of the robot's location are maintained and updated during navigation in order to cope with sensor aliasing and landmark-matching failures due to factors such as unknown obstacles inside the corridors.

Distributed navigation system

Abstract: Computer-assisted navigation is achieved with component-oriented programming and instructions that provide a distributed component programming navigation system. The computer-assisted navigation is achieved with a computing device having program memory. Operationally, the component-oriented application loaded in the memory provides a distributed navigation system comprising a User Interface component, a Service Manager component, a User Positioning category of components that provides a user position based on navigation sensor data, and a Mapping category of components that accesses a map database and places the user position on a road segment of the map database. The components within the component-oriented application are managed by the service manager component to perform distributed navigation services.

Navigation system, navigation apparatus, and server apparatus

Abstract: The Navigation Apparatus transmits to a server apparatus a current position, a destination, and an area of a geographical information stored in a geographic information memory part. The server apparatus receives them to calculate one or more potential routes from the current position to the destination; sets a potential passing-by point for each potential route in the area of the geographic information stored in the Navigation Apparatus; and transmits those potential passing-by points to the Navigation Apparatus. The Navigation Apparatus receives them to calculate traveling routes from the current position to the potential passing-by points and selects one of the potential passing-by points, thereby deciding the passing-by point as a temporary destination within the area of the geographic information stored in the Navigation Apparatus. In this way, the route navigation can be realized without increasing the memory capacity of the geographic information memory part of the Navigation Apparatus. Additionally, since only necessary information, such as the geographic information, passing-by points and the like, are transmitted and received, the communication cost can be reduced.

Understandable navigation of an information array

Abstract: To prevent disorientation, the described systems and methods continuously maintain a visual landmark during electronic navigation of a one-dimensional list of items or a two-dimensional information grid in situations where only a part of the list or the information grid is displayed at a given time. In one implementation, an electronic program guide is dynamically scaled to maintain visibility of a navigation starting point during browsing with rudimentary navigation controls, but reverts back to a legible scale when navigation stops.

Navigation system and navigation equipment

Abstract: A navigation system and navigation equipment which reduce the time required for radio transmissions to implement fast navigational guidance. The navigation equipment communicates bi-directionally by radio with a navigation server, thereby providing navigational guidance. The navigation equipment transmits position data delivered by a GPS receiver to the navigation server through a communication device and acquires, from the communication device, map data for display indicative of a map of a surrounding area including a self-location provided by the position data sent back from the navigation server. The navigation equipment then performs map matching between road information contained in the acquired map data for display and the position information, thereby determining a current position on the road, thereby displaying a map in the form of an image on a display unit in accordance with the map data for display and displaying the current position determined by the map matching on the map displayed in the form of an image.
