Furthermore, the information itself, which can potentially be made available to a user, in some cases have a location reference, ie they are relevant only for specific locations or have in certain places a higher information content for the users.

Description

Technisches GebietTechnical area

Die Erfindung bezieht sich auf ein Verfahren zur Versorgung eines programmgestützten Informationssystems mit gezielten Ortsinformationen, bei dem durch das Informationssystem in Abhängigkeit eines sensorisch erfassbaren, personen- oder objektspezifischen Ortes zumindest eine Auswahl bestimmter Ortsinformationen bereitgestellt wird.
Derartigen Verfahren liegen Programmmodelle zur Handhabung von Ortsinformationen in Computerprogrammen zugrunde, die ihren Nutzern in Abhängigkeit von deren aktuellen oder zukünftigen Aufenthaltsort Informationen bereitstellen. In diesen Computerprogrammen erhalten Nutzer genau diejenigen Informationen, die sie tatsächlich benötigen, zu dem Zeitpunkt und an dem Ort, an dem entsprechender Bedarf auftritt.The invention relates to a method for supplying a program-based information system with targeted location information, in which at least one selection of specific location information is provided by the information system as a function of a sensory, personal or object-specific location.
Such methods are based on program models for handling location information in computer programs that provide information to their users depending on their current or future location. In these computer programs, users get exactly the information they need at the time and place they need it.

Der Dimension "Ort" kommt somit ein wesentlicher Gesichtspunkt zu, durch den die Informationsversorgung von Nutzern bei derartigen Computerprogrammen optimiert wird. Sie spielt in verschiedener Hinsicht eine bedeutende Rolle. So ist der Bedarf von Nutzern nach bestimmten Informationen bspw. abhängig vom Aufenthaltsort der Nutzer selbst. So werden bestimmte Informationen nur an bestimmten Orten benötigt. Weiterhin haben die Informationen selbst, die einem Nutzer potenziell zur Verfügung gestellt werden können, in einigen Fällen einen Ortsbezug, d.h. sie sind nur für bestimmte Orte relevant oder haben an bestimmten Orten einen höheren Informationsgehalt für die Nutzer. Selbst auch die Kommunikationsmedien, die derartige Computerprogramme nutzen, um die gewünschten Informationen einem Nutzer bereitzustellen, sind abhängig vom Aufenthaltsort des Nutzers.The dimension "location" thus has an essential aspect by which the information supply of users in such computer programs is optimized. It plays a significant role in several ways. For example, users' need for specific information depends, for example, on the whereabouts of the users themselves. Thus, certain information is required only in certain locations. Furthermore, the information itself, which can potentially be made available to a user, in some cases have a location reference, ie they are relevant only for specific locations or have in certain places a higher information content for the users. Even the communication media, the Such computer programs use to provide the desired information to a user, depending on the whereabouts of the user.

Derartige Computerprogramme müssen demzufolge in der Lage sein, Ortsinformationen sowohl in Zusammenhang mit dem Informationsbedarf von Nutzern, mit den Informationen selbst, mit Kommunikationsmedien und schließlich mit dem aktuellen und auch mit zukünftigen Aufenthaltsorten von Nutzern und anderen relevanten Objekten zu verarbeiten. Dazu ist die Verwendung von Sensorsystemen notwendig, die Personen und Objekte orten können. Diese Sensoren liefern Ortsinformationen, die ebenfalls darstell- und verarbeitbar sein müssen.Such computer programs must therefore be able to process location information both in connection with the information needs of users, with the information itself, with communication media, and ultimately with the current and future locations of users and other relevant objects. This requires the use of sensor systems that can locate people and objects. These sensors provide location information that must also be presentable and processable.

Stand der TechnikState of the art

Derzeit gibt es ein Vielzahl von Computerprogrammen, die Nutzern in Abhängigkeit ihres aktuellen oder künftigen Aufenthaltsorts Informationen bereitstellen.
Deratige Programme werden als Location Based Services bezeichnet und haben allesamt gemeinsam, dass sie ein Datenmodell für mögliche Aufenthaltsorte von Personen und Objekten enthalten. Aus dem Dokument WO 00/70504 ist ein System bekannt, bei dem einem Anwender "Location Based Services" in abhangigkeit von seinen Präferenzen angeboten werden.Currently, there are a variety of computer programs that provide information to users depending on their current or future location.
Such programs are referred to as location-based services and all have in common that they contain a data model for possible locations of people and objects. From document WO 00/70504 a system is known in which a user is offered "Location Based Services" depending on his preferences.

Prinzipiell gibt es zwei Möglichkeiten, Orte in einem Datenmodell zu repräsentieren. Sie können in Form geometrischer Daten, d.h. bezogen auf ein n-dimensionales Koordinatensystem, oder als symbolische Daten, d.h. als eine Menge von Symbolen oder Namen, die über Beziehungen verknüpft sind, abgebildet werden. Obwohl die meisten heute bekannten Systeme sich auf eine der möglichen Ortsrepräsentationen beschränken, gibt es bereits Ansätze, die eine Integration geographischer und symbolischer Orte vornehmen. Jedoch unterliegen die derzeit verwendeten Ortsmodelle einigen Beschränkungen, die sie für eine personalisierte, bedarfsgerechte Informationsversorgung ungeeignet machen.In principle, there are two ways to represent places in a data model. They may be in the form of geometric data, i. based on an n-dimensional coordinate system, or as symbolic data, i. as a set of symbols or names linked through relationships. Although most systems known today are limited to one of the possible location representations, there are already approaches that integrate geographical and symbolic locations. However, currently used location models are subject to some limitations that make them unsuitable for personalized, on-demand information delivery.

Zum einen gehen diese Modelle und die Systeme, in denen sie verwendet werden, von einem statischen Informationsbedarf der Nutzer aus, den das System selbst festlegt. Dieser Bedarf ist nicht oder nur in engen Grenzen vom Nutzer zu beeinflussen. Weiterhin kommt derzeit in einem Computerprogramm in der Regel nur ein einziges Sensorsystem zur Ortung zum Einsatz. Aus diesem Grund wird von jedem Programm nur ein enger Teilbereich möglicher Ortsinformationen abgedeckt.On the one hand, these models and the systems in which they are used assume a static need for information from the users that the system itself sets. This need is not or only within narrow limits of the user to influence. Furthermore, currently only a single sensor system is used for locating in a computer program. For this reason, each program covers only a narrow subset of possible location information.

Die verwendeten Modelle verwenden jeweils eine unterschiedliche Semantik; eine einheitliche Repräsentation von Orten in Computerprogrammen ist derzeit nicht bekannt. Zudem es ist insbesondere derzeit nur sehr begrenzt möglich, einen Ort, der in einer bestimmten Repräsentationsform vorliegt, in einen Ort einer anderen Repräsentationsform zu transformieren. Dies gilt besonders für unterschiedliche symbolische Orte. Eine dertige Transformation ist jedoch notwendig, um Ortsinformationen in den verschiedenen dargestellten Bereichen, in denen sie für die bedarfsgerechte Informationsversorgung relevant sind, adäquat zu verarbeiten.The models used each use a different semantics; a uniform representation of locations in computer programs is currently unknown. In addition, it is currently only possible to a very limited extent to transform a place which exists in a certain form of representation into a place of another form of representation. This is especially true for different symbolic places. However, such transformation is necessary to adequately process location information in the various areas depicted where they are relevant to on-demand information delivery.

Die im Zusammenhang mit der Repräsentation von Orten wichtigen Angaben zu Beziehungen von Orten untereinander wie Distanz, Enthaltenseinsbeziehungen, d.h. eine Überprüfung dahingehend, ob ein Ort in einem anderen Ort enthalten ist, bspw. Zimmer 23 ist in der 2. Etage des Hauses X enthalten, oder Überschneidungen sind mit den bisherigen Programmen nicht oder nur unbefriedigend gelöst. Ebenfalls sind mit den bekannten Programmen Beziehungen zwischen Orten und Personen bzw. Objekten nicht oder nur in geringem Maße abbildbar, d.h. individuelle Informationen können in Abhängigkeit zum aktuellen Aufenthaltsort einer Person oder eines Objektes nicht abgreufen bzw zur Verfügung gestellt werden.The important in connection with the representation of places important information on relationships between places such as distance, containment relationships, i. a check on whether a place is included in another place, for example. Room 23 is included in the 2nd Floor of House X, or overlaps are not or only unsatisfactorily resolved with the previous programs. Likewise, with the known programs, relationships between places and persons or objects can not or only to a small extent be mapped, i. Individual information can not be retrieved or made available depending on the current location of a person or an object.

Erfindungsgemäß setzt sich ein Verfahren zur Versorgung eines programmgestützten Informationssystems mit gezielten Ortsinformationen, bei dem durch das Informationssystem in Abhängigkeit eines sensorisch erfassbaren, personen- oder objektspezifischen Ortes zumindest eine Auswahl bestimmter Ortsinformationen bereitgestellt wird, aus folgenden Verfahrenschritten zusammen:According to the invention, a method for supplying a program-supported information system with targeted location information, in which at least one selection of specific location information is provided by the information system as a function of a sensor-detectable, person or object-specific location, consists of the following method steps:

In einem ersten Schritt wird mit einem technischen Ortserfassungsystem ein Ort, an dem sich bspw. eine Person aktuell aufhält, sensoriell erfasst. Die auf dieser Weise sensoriell erfassten Ortsdaten werden anschließend in eine Ortsdarstellungform überführt, die mit einem Referenzsystem, innerhalb dem die Ortsdaten räumlich zuordenbar sind, sowie mit einer hierarchischen Struktur assoziiert werden.In a first step, with a technical location detection system, a location where, for example, a person is currently located is detected by sensors. The location data sensory detected in this way are then converted into a location representation, which are associated with a reference system within which the location data can be spatially assigned, as well as with a hierarchical structure.

Die mit jeweils einem entsprechenden Referenzsystem sowie der mit dem jeweiligen Referenzsystem eigenen Hierachie assoziierten Ortsdarstellungsformen werden im weiterem in einer Ortsmenge und/oder in Form von Ortsvektoren zusammengefasst, in denen die Ortsdarstellungsformen wenigstens zweier Orte in einer vorgegebenen Reihenfolge miteinander verknüpft sind. Alternativ zum vorherigen Schritt der Ortsmengen- bzw. Ortsvektorenbildung oder aber auch in Kombination werden nach folgend Orts- und/oder Ortsvektorrelationen zwischen den Orten und Personen bzw.The locational forms associated with a corresponding reference system and the hierarchy associated with the respective reference system are further summarized in a set of locations and / or in the form of location vectors in which the locales of at least two locations are linked together in a predetermined order. As an alternative to the previous step, the Ortsmengen- or location vector formation or in combination but are following the following location and / or location vector relations between the places and people or

Objekten innerhalb sogenannter Positionierter Ortsmengen gebildet, um schließlich durch Anwenden von Operationen bei Übereinstimmung zwischen Orten, d.h. zwischen den Ortsdaten, die durch Ortssensoren gewonnen wurden, und in Informationsbedürfnissen abgespeicherten Orten, eine Generierung oder Bereitstellung von ortsabhängigen personen- oder objektspezifischen Informationen zu ermöglichen.Objects are formed within so-called Positional Locations, to finally by applying operations in case of coincidence between locations, i. between the location data obtained by location sensors and locations stored in information needs, to enable generation or provision of location-dependent personal or object-specific information.

In dem erfindungsgemäßen Verfahren werden die sensorisch erfassten Ortsdaten mittels sogenannter Sensoradaptoren, die spezielle Teile eines Computerprogramms darstellen, in Ortsdarstellungsformen umgewandelt, bspw. in Form von Koordinatenwerten eines Referenzsystems. Die in einer deratigen Ortsdarstellungsform transformierten Ortsdaten werden in Ortsmengen oder Ortsvektoren gruppiert, die man als grundlegende Repräsentationsformen von Orten ansehen kann. Ortsmengen sind dabei Sammlungen unsortierter Ortsangaben, die entweder aus einem oder mehreren Elementen bestehen können. Ortsmengen mit genau einem Element bilden sogenannte atomare Orte ab, während Ortsmengen mit mehr als einem Element zusammengesetzte Orte oder Ortsaufzählungen enthalten. Die einzelnen Orte bzw. Ortsdaten innerhalb einer solchen Ortsmenge werden über bool'sche Operatoren miteinander verknüpft. Ortsvektoren enthalten an ihren Knoten Orte in einer festen Reihenfolge; sie ermöglichen damit beispielsweise die Abbildung von Routen. Die Kanten innerhalb von Ortsvektoren geben Informationen über die Strecke zwischen den Ortsknoten, die sie verknüpfen. Sie können ebenfalls eine Ortsmenge oder ein Ortsvektor sein.In the method according to the invention, the location data acquired by sensors are converted into local representation forms by means of so-called sensor adapters, which represent special parts of a computer program, for example in the form of coordinate values of a reference system. The location data transformed in such a spatial presentation form is grouped into place sets or place vectors which can be regarded as basic representation forms of places. Spaces are collections of unsorted locations, which can consist of one or more elements. Spaces with exactly one element represent so-called atomic places, while places with more than one element contain compound places or place enumerations. The individual locations or location data within such a location are linked together via Boolean operators. Location vectors contain locations in a fixed order at their nodes; They allow, for example, the mapping of routes. The edges within location vectors give information about the link between the location nodes that link them. They can also be a place set or a place vector.

Für die Ordnung der Orte untereinander ist eine Baumstruktur vorgesehen, die es ermöglicht, Orte hierarchisch anzuordnen und damit komplexe Ortsstrukturen und sogenannte Enthaltenseinsbeziehungen abzubilden, d.h. es ist möglich nachzuprüfen, ob sich bspw. ein Zimmer x in der Etage y innerhalb eines Hauses z befindet.For the order of the places among each other, a tree structure is provided, which makes it possible to arrange places hierarchically and thus to map complex location structures and so-called containment relationships, i. It is possible to check if, for example, a room x is located in the floor y within a house z.

Im Gegensatz zum eingangs beschriebenen Stand der Technik werden Orte selbst nicht in verschiedene Klassen bzw. in verschiedene Referenzsysteme unterteilt, wie bspw. ein rein geographisches (Länge/Breite) oder rein symbolisches (Ortsname, Strassenname etc.) Referenzsystem. Das Ortsmodell bzw. das Verfahren assoziiert mittels der Sensoradaptoren vielmehr jeden Ort mit einem Referenzsystem, dem dieser Ort angehört. In diesen Referenzsystemen sind die Charakteristika der Orte, die dem System angehören, einschließlich ihrer Dimensionen, zulässigen Wertebereiche, Beziehungen der Dimensionen untereinander und zu Dimensionen anderer Referenzsysteme hin-terlegt.In contrast to the prior art described above, places themselves are not subdivided into different classes or into different reference systems, such as For example, a purely geographical (length / width) or purely symbolic (place name, street name, etc.) reference system. Rather, the location model or the method associates by means of the sensor adapters each location with a reference system to which this location belongs. In these reference systems, the characteristics of the locations belonging to the system, including their dimensions, permissible ranges of values, relations of the dimensions with each other and dimensions of other reference systems are stored.

Das Verfahren sieht weiterhin Transformationsvorschriften vor, die auf den Referenzsystemen operieren und Orte unterschiedlicher Referenzsysteme ineinander überführen können. Die Prüfung von Orten auf Enthaltensein, Gleichheit oder Zwischenraum wird damit sowohl für Orte, die auf demselben Referenzsystem basieren, mittels dieses Referenzsystems, als auch für Orte mit unterschiedlichen Referenzsystemen basierend auf den Transformationsvorschriften ermöglicht.The method also provides transformation rules that can operate on the reference systems and interleave locations of different reference systems. The examination of locations for containment, equality, or space is thus made possible both for locations based on the same reference system by means of this reference system and for locations with different reference systems based on the transformation rules.

Das Ortsmodell bzw. Verfahren definiert weiterhin eine Beziehung von Personen und Objekten zu Orten über die Modellierung von sogenannten Präpositionen. Präpositionen können den Orten einer Ortsmenge oder eines Ortsvektors zugeordnet werden. Sie sind außerdem um Distanzangaben erweiterbar. Distanzen bestehen typischerweise aus einer Maßeinheit, die eine metrische, zeitliche oder örtliche Einheit sein kann, einer Mengeneinheit sowie einem Operator. Auch werden Distanzen an anderen Stellen des Ortsmodells, insbesondere in den Referenzsystemen, verwendet. Es ist somit möglich Distanzen zwischen Orten und Personen bzw. Objekten sowie zwischen einzelnen Orten zu ermitteln.The location model or method further defines a relationship of persons and objects to places via the modeling of so-called prepositions. Prepositions can be assigned to the locations of a place set or a place vector. They are also expandable by distance. Distances typically consist of a unit of measure, which may be a metric, temporal, or local unit, a unit of measure, and an operator. Also, distances at other locations of the location model, especially in the reference systems, are used. It is thus possible to determine distances between places and persons or objects as well as between individual places.

Weiterhin vermag das Verfahren die Genauigkeit sowie die Wahrscheinlichkeit von Ortsangaben abzubilden. Dies ist insbesondere relevant für die Integration verschiedener Ortssensoren, die Ortungsdaten oft mit einer Unschärfe hinsichtlich ihrer Granularität und der Übereinstimmung von tatsächlichem mit geortetem Ort liefern. Es ist überdies auch möglich Referenzsysteme, zulässige Präpositionen, Distanzangaben und Wertebereiche dynamisch zu ergänzen, sofern dies ein Anwenderprogramm erfordert.Furthermore, the method can map the accuracy and the probability of location information. This is particularly relevant to the integration of various location sensors, which often provide location data with a blur in terms of their granularity and the coincidence of actual location with location. It is also possible to supplement reference systems, permissible prepositions, distance specifications and value ranges dynamically, if required by a user program.

Durch das Verfahren wird weiter die Möglichkeit geschaffen, Angaben zu Orten bezüglich Ortssensoren, Orts- und/oder Personen-spezifische Informationsbedürfnisse, Kommunikationskanälen und Informationen selbst in Computerprogrammen einheitlich zu verwalten. Auf diese Weise werden Computerprogramme in die Lage versetzt, den vorherrschenden Trend zur Personalisierung und Individualisierung der bereitgestellten Dienste und Informationen auch auf die Dimension Ort hin auszudehnen. So erhalten Nutzer von Computerprogrammen nur diejenigen Informationen, die sie wirklich benötigen und die an ihrem Aufenthaltsort relevant für sie sind.The method further provides the possibility of uniformly managing information regarding locations with regard to location sensors, location and / or person-specific information needs, communication channels and information even in computer programs. In this way, computer programs are enabled to extend the prevailing trend towards personalization and individualization of the services and information provided to the local dimension as well. Thus, users of computer programs only receive the information that they really need and that are relevant to them at their place of residence.

Die durch das Verfahren bereitgestellte Funktionalität stellt im Vergleich zu heutigen Computerprogrammen einen erheblichen Mehrwert für die Nutzer dar und verschafft ihren Anbietern erhebliche Wettbewerbsvorteile. Diese werden dadurch verstärkt, dass das vorliegende Verfahren und Modell dynamisch erweiterbar ist und in verschiedensten Anwendungsgebieten zum Einsatz kommen kann. So ist es möglich das erfindungsgemäße Verfahren bei geringem Zeit- und Kostenaufwand in Computerprogramme zu integrieren.The functionality provided by the method represents a significant added value for users compared to today's computer programs and provides their providers with significant competitive advantages. These are reinforced by the fact that the present method and model is dynamically expandable and can be used in a wide variety of application areas. Thus, it is possible to integrate the inventive method with little time and cost in computer programs.

Weiterhin können Anbieter von Computerprogrammen schnell und kostengünstig auf veränderte Anforderungen an die Programme reagieren. Besonders vorteilhaft lässt sich das erfindungsgemäße Modell auch in innovativen Anwendungen des so genannten "intelligenten Internet" einsetzen. Hier kann die vorherrschende Informationsflut durch eine gezielte Versorgung mit Informationen, die auch ortsabhängig aufbereitet und bereitgestellt werden, eingedämmt werden. Da diese Art der Anwendungen sich durch eine starke Verteilung der Datenverarbeitungsstationen auszeichnet, eignet sich das vorliegende Verfahren besonders gut, um durch seine Generität und Erweiterbarkeit eine einheitliche Plattform für Anwendungen des intelligenten Internet zu ermöglichen.Furthermore, providers of computer programs can respond quickly and cost-effectively to changing requirements on the programs. The model according to the invention can also be used particularly advantageously in innovative applications of the so-called "intelligent Internet". Here, the prevailing flood of information can be contained by a targeted supply of information that is also prepared and provided depending on the location. Since this type of applications is characterized by a strong distribution of the data processing stations, the present method is particularly well suited to its generation and expandability to provide a unified platform for applications of intelligent Internet.

Das erfindungsgemäße Verfahren ist in einem Modellversuch bereits in einer Plattform zur Bereitstellung personalisierter Verkehrsinformationen erfolgreich eingesetzt worden. So werden auf dieser Plattform registrierte Nutzer in Abhängigkeit von der aktuellen Verkehrslage zu einem Zeitpunkt benachrichtigt, zu dem sie eine geplante Autofahrt antreten, um zu einem gegebenen Zeitpunkt ein gegebenes Ziel zu erreichen. Dabei werden Pufferzeiten zwischen Benachrichtigung und Abfahrzeitpunkt sowie präferierte Fahrtrouten des Nutzers berücksichtigt. Auch ist es mölgich dem Nutzer auch während der Fahrt zu seinem Ziel aktuelle Informationen über die Verkehrslage auf der Fahrtstecke, mögliche Staus und Ausweichrouten in Abhängigkeit von der aktuellen Position der Nutzer zuzustellen. In diesem Beispiel liegt ein ortsabhängiger Informationsbedarf vor, der besagt, dass ein Nutzer aktuelle Stauinformationen für seine Route und sein Fahrtziel erhalten möchte, wenn er sich auf der Autobahn befindet. In diesem Informationsbedarf ist demnach eine Ortsangabe in der Form "auf der Autobahn" ent-halten. Um den Bedarf zu befriedigen, wird der Nutzer nach Fahrtantritt über Sensorsysteme geortet. Diese Systeme liefern den aktuellen Aufenthaltsort des Nutzers in Form von Gauss-Krüger-Geokoordinaten. Die Verkehrsinformationen selbst sind mit Ortsinformationen in Form von Autobahnkürzeln in Verbindung mit Kürzeln für Anschlussstellen und Autobahnkreuze versehen. Das Ortsmodell ist zuständig für die Abbildung, Verwaltung und Transformation dieser Ortsangaben in ihren unterschiedlichen Formaten. Die Ortsangaben Autobahn, Gauss-Krüger-Koordinaten und Autobahn- bzw. Anschlussstellen-/Autobahnkürzel werden in Ortsobjekten abgebildet, die sich jeweils auf ein semantisches Referenzsystem für Transportlinien bzw. für Geokoordinaten beziehen. Die präferierten Fahrtrouten der Nutzer werden als Ortsvektoren abgebildet, auf deren Kanten das Fortbewegungsmittel angegeben ist. Über Transformationsalgorithmen wird ermittelt, ob die Koordinaten, die ein Ortungsvorgang liefert, mit der Ortsspezifikation des Informationsbedarfs übereinstimmt. Weiterhin werden, wenn dies der Fall ist, diese Koordinaten in das Ortsformat umgewandelt, das in den Verkehrsinformationen vorliegt.The method according to the invention is already successful in a model experiment in a platform for providing personalized traffic information been used. For example, users registered on this platform will be notified, depending on the current traffic situation, at a time when they are planning a car journey to reach a given destination at a given time. Here, buffer times between notification and departure time as well as preferred routes of the user are taken into account. It is also important for the user to be provided with up-to-date information about the traffic situation on the route during the journey to his destination, possible traffic jams and alternative routes depending on the current position of the users. In this example, there is a location-dependent need for information stating that a user wants to receive up-to-date congestion information for their route and destination when they are on the highway. In this information requirement is therefore a location in the form "on the highway" ent-hold. In order to meet the demand, the user is located after departure via sensor systems. These systems provide the current location of the user in the form of Gauss-Krüger geo-coordinates. The traffic information itself is provided with location information in the form of motorway codes in connection with abbreviations for junctions and motorway junctions. The location model is responsible for the mapping, administration and transformation of these locations in their different formats. The location details of the motorway, Gauss-Krüger coordinates and motorway or connection point / motorway abbreviations are mapped in local objects, each of which refers to a semantic reference system for transport lines or for geo-coordinates. The preferred driving routes of the users are depicted as position vectors, on the edges of which the means of locomotion is indicated. Transformation algorithms are used to determine if the coordinates provided by a locate operation match the location specification of the information needs. Furthermore, if so, these coordinates are converted to the location format present in the traffic information.

Wege zur Ausführung der Erfindung, gewerbliche VerwendbarkeitWays to carry out the invention, industrial usability

In Figur 1 ist ein typisches Ablaufschema des Verfahrens dargestellt, das die Struktur sowie die Zusammenhänge der zuvor erläuterten Elemente Ortsmengen, Ortsvektoren, Präpositionen etc. zeigt.FIG. 1 shows a typical flowchart of the method, which shows the structure as well as the relationships of the previously explained elements of sets, position vectors, prepositions, etc.

Dargestellt sind zunächst Ortsmengen OM, die Orte und/oder Ortsvektoren enthalten, sowie Ortsvektoren OV, die aus mindestens zwei sensorisch erfassten Orten bestehen.Plotted are first sets of locations OM containing locations and / or location vectors, as well as location vectors OV, which consist of at least two sensory detected locations.

Mit den Orten O selbst ist eine Struktur S assoziiert. Diese Struktur S bildet sogenannte Enthaltenseinsbeziehungen zwischen den einzelnen Orten O ab. Die Struktur S weist hierzu Knoten K und Blätter B auf, die einen Baum bilden, wodurch eine hierarchische Anordnung von Orten ermöglicht wird. Beispielsweise ist der Ort "Raum 1.29", der einem Blatt entspricht, enthalten in dem "Gebäude der Firma X", die einem Knoten entspricht, das wiederum enthalten ist im Ort "Dortmund", der dem Knoten entspricht.A structure S is associated with the places O themselves. This structure S forms so-called containment relationships between the individual locations O. For this purpose, the structure S has nodes K and leaves B, which form a tree, which enables a hierarchical arrangement of locations. For example, the location "space 1.29" corresponding to a leaf is included in the "building of firm X" corresponding to a node contained in the place "Dortmund" corresponding to the node.

Zusätzlich zu diesen reinen Ortsangaben ermöglicht das Verfahren die Abbildung von Präpositionen P, d.h. Beziehungen zwischen Personen oder Objekten und Orten wie beispielsweise "in", "20 km vor", "außerhalb von". Um dies zu ermöglichen, enthält das Modell eine Positionierte Ortsmenge PO. In dieser Positionierten Ortsmenge PO sind so genannte Ortsrelationen OR enthalten; weiterhin können Vektorrelationen VR in ihr enthalten sein. Orts- und Vektorrelationen entsprechen den zuvor erläuterten Ortsmengen OM und Ortsvektoren OV, erweitern diese aber um die erforderlichen Präpositionen P. Eine Ortsrelation OR enthält einen Ort O sowie eine Präposition P, die sich auf diesen Ort O bezieht, bspw. "20 km im Umkreis von München". Eine Vektorrelation VR enthält analog einen Ortsvektor OV sowie eine zugehörige Präposition P, bspw. "auf der Route zur Arbeit".In addition to these pure locations, the method allows the mapping of prepositions P, ie relationships between persons or objects and locations such as "in", "20 km before", "outside of". To enable this, the model contains a Positioned Location PO. In this position Location PO are so-called location relations OR included; furthermore, vector relations VR can be contained in it. Local and vector relations correspond to the above-described local quantities OM and position vectors OV, but extend them by the required prepositions P. A local relation OR contains a location O as well as a preposition P which refers to this location O, eg "20 km in the vicinity from Munich". A vector relation VR similarly contains a position vector OV and an associated preposition P, eg "on the route to work".

Die Klasse Relation R stellt sicher, dass Ortsrelationen OR und Vektorrelationen VR vom selben Typ sind und ermöglicht die Vererbung von Operationen OP auf Orts- und Vektorrelationen. Sie ist mit den beschriebenen Präpositionen P assoziiert. Die Präpositionen P wiederum können eine Distanzangabe D besitzen, die aus einer Mengenangabe, bspw. "20 km im Umkreis von München", einer Maßeinheit, bspw. "km" und einem Operator, bspw. "im Umkreis von" bestehen.The Relation R class ensures that OR and vector relations VR are of the same type and allows the inheritance of OP operations on location and vector relations. It is associated with the prepositions P described. The prepositions P in turn may have a distance specification D, which consist of a quantity, for example "20 km in the Munich area", a unit of measure, for example "km" and an operator, for example "in the vicinity of".

Figur 2 veranschaulicht die Zuordnung von Orten O zu Referenzsystemen RS. Jeder Ort O wird durch eine Menge von Koordinaten KO beschrieben. Diese Koordinaten KO legen die Lage des Ortes O innerhalb eines Referenzsystems RS eindeutig fest. Unter Koordinaten KO sind nicht nur physikalische Koordinaten wie beispielsweise durch GPS-Systeme gelieferte Längen- und Breitengrade zu verstehen. Vielmehr sind die Koordinaten eines Ortes Werte beliebigen Typs, die sich auf eine Dimension beziehen. Beispiele hierfür sind die Dimension Raumnummer mit dem Wert 1.29 oder die Dimension "Städtename" mit dem Wert München. So gibt eine Reihe alternativer Referenzsysteme, in denen Koordinaten die Lage eines Ortes definieren, wie bpsw. Geographisches RS, Gebäude-RS, Gegenstands-RS oder UTM-RS.FIG. 2 illustrates the assignment of locations O to reference systems RS. Each location O is described by a set of coordinates KO. These coordinates KO uniquely determine the location of the location O within a reference system RS. Coordinates KO are understood to mean not only physical coordinates, such as longitude and latitude, for example, provided by GPS systems. Rather, the coordinates of a place are values of any type that refer to a dimension. Examples are the dimension room number with the value 1.29 or the dimension "city name" with the value Munich. Thus, there are a number of alternative reference systems in which coordinates define the location of a place, such as bpsw. Geographic RS, Building RS, Item RS or UTM-RS.

Die Ortungsgenauigkeit mit der verschiedene Sensorsysteme zur Ortsdetektion arbeiten wird in dem Verfahren ebenfalls berücksichtigt, indem eine für das jeweilige Sensorsystem spezifische Genauigkeit G mit den Werten W der sensorisch erfassten Koordinaten assoziiert wird.The location accuracy with which different sensor systems work for location detection is likewise taken into account in the method in that an accuracy G specific to the respective sensor system is associated with the values W of the sensory coordinates.

Auf diese Weise lässt sich beispielsweise abbilden, dass die einzelnen Werte W der Koordinaten bspw. die der Dimensionen D "Längengrad und Breitengrad" aufweisen und die Genauigkiet für eine Ortsangabe etwa 10 m beträgt.In this way, it can be shown, for example, that the individual values W of the coordinates have, for example, those of the dimensions D "longitude and latitude" and the accuracy for a location is about 10 m.

So beziehen sich Koordinaten KO auf genau ein Referenzsystem RS, das durch das Sensorsystem vorgegeben ist. Dieses Referenzsystem RS schreibt vor, welchen Eigenschaften die zugehörigen Koordinaten KO genügen müssen. Dies geschieht durch die Vorgabe der Dimensionen D, auf die sich die Werte W der Koordinaten KO beziehen und definieren zugleich den gültigen Wertebereiche.Thus, coordinates KO refer to exactly one reference system RS, which is predetermined by the sensor system. This reference system RS prescribes which properties the associated coordinates KO must satisfy. This is done by specifying the dimensions D, to which the values W of the coordinates KO refer, and at the same time define the valid value ranges.

Ferner wird durch das Referenzsystem RS festgelegt, welche Attribute Orte enthalten. Da jedes Referenzsystem einen Ursprung besitzt wird durch diesen Ursprung jedem Ort ein hierarchisch übergeordneter Ort oder eine übergeordnete Systemgrenze zugeordnet. Sofern es sinnvoll ist, sind in den Referenzsystemen RS Beziehungen zwischen den Orten dieses Referenzsystems hinterlegt. Für Räume kann dies beispielsweise ein Plan der durch das Referenzsystem abgebildeten Räume sein, in dem die Anordnung der Räume dargestellt wird.Furthermore, the reference system RS determines which attributes contain locations. Since each reference system has an origin, this origin assigns a hierarchically superior location or a higher-level system boundary to each location. If it makes sense, relationships between the locations of this reference system are stored in the reference systems RS. For rooms, this may be, for example, a plan of the spaces imaged by the reference system, in which the arrangement of the rooms is shown.

Weiterhin enthalten die Referenzsysteme RS Transformationsvorschriften für die Überführung von Orten, die sich auf ein Referenzsystem beziehen, in Orte mit einem anderen Referenzsystem und damit anderen Koordinaten.Furthermore, the reference systems RS contain transformation instructions for the transfer of locations which relate to one reference system, to locations with a different reference system and thus to other coordinates.

Die Referenzsysteme sind außerdem mit Sensoradaptoren verknüpft. Dies sind spezielle Teile eines Computerprogramms, die Ortungsdaten von Sensoren (GPS-Empfängern, Transpondersystemen, elektronischen Terminkalendern, Benutzereingaben etc.) entgegennehmen und in Koordinatenwerte eines Referenzsystems überführen.The reference systems are also linked to sensor adapters. These are special parts of a computer program that receive location data from sensors (GPS receivers, transponder systems, electronic diaries, user inputs, etc.) and convert them into coordinate values of a reference system.

Mit dem erfindunsgemäßen Verfahren ist es in erster Linie möglich Orte in Computerprogrammen zur personalisierten, bedarfsgerechten Informationsversorgung einheitlich abzubilden und so ortsabhängig relevante Informationen den Benutzern der Computerprogramme zur Verfügung zu stellen.With the method according to the invention, it is possible in the first place to uniformly map locations in computer programs for personalized, needs-based information provision and thus to make location-relevant information available to the users of the computer programs.

Besondere Bedeutung kommt dem Verfahren allerding zu, wenn die Informationsbedürfnisse von Nutzern von ihrem aktuellen oder prognostizierten Aufenthaltsort abhängen. Dies ist zum einen der Fall, wenn ein Informationsbedürfnis nur an bestimmten Orten auftritt oder aber, wenn die Informationen selbst, die für einen Nutzer relevant sind, dadurch definiert werden, an welchem Ort sich der Nutzer aufhält.The method is of particular importance if the information needs of users depend on their current or predicted whereabouts. This is the case, on the one hand, when an information need occurs only in certain places or when the information itself, which is relevant to a user, is defined by the location of the user.

Hier dient das erfindunsgemäße Verfahren dazu, aktuelle und zukünftige Aufenthaltsorte von Nutzern sowie Objekten abzubilden. Weiterhin bildet das Verfahren auch Ortsangaben in Zusammenhang mit dem Informationsbedürfnis von Nutzern ab, bspw. "Nachricht, wenn Frau X. das Gebäude betritt" oder "Benachrichtigung über Staus auf meiner Strecke". Eine wichtige Aufgabe der Computerprogramme, die das erfindunsgemäße Verfahren einsetzen, besteht auch darin zu überprüfen, ob ein aktueller oder prognostizierter Aufenthaltsort mit Ortsbedingungen mit dem Informationsbedürfnis eines Nutzers deckungsgleich sind. Hierzu werden Daten von Sensoren erfasst. Dies geschieht durch die oben erwähnten Sensoradaptoren.Here, the method according to the invention serves to map current and future locations of users and objects. Furthermore, the method also maps location information in connection with the information needs of users, for example. "Message when Mrs. X. enters the building" or "Notification of traffic jams on my route". An important task of the computer programs which use the method according to the invention is also to check whether a current or predicted location with location conditions is congruent with the information requirement of a user. For this purpose, data is acquired by sensors. This is done by the above-mentioned sensor adapters.

Die Sensoren können dabei von verschiedener Art sein. Sie lassen sich grob in genuine Ortungssysteme und abgeleitete Ortungssysteme klassifizieren. Genuine Ortungssysteme sind Sensoren, die für den Zweck der Ortsbestimmung entwickelt sind, wie beispielsweise GPS-, Transponder- oder Infrarotsysteme. Abgeleitete Ortungssysteme sind Systeme, die ursprünglich anderen Zwecken als der Ortung dienen, die jedoch auch für die Bestimmung von Aufenthaltsorten von Personen und Sachen verwendet werden können. Hierzu zählen Systeme zur Arbeitszeiterfassung, elektronische Terminkalender, Raumbelegungspläne, explizite Benutzereingaben etc..The sensors can be of different types. They can be broadly classified into genuine location systems and derived location systems. Genuine location systems are sensors designed for the purpose of location, such as GPS, transponder or infrared systems. Derived location systems are systems that originally serve purposes other than location, but can also be used to determine the location of people and things. These include systems for working time recording, electronic appointment calendars, occupancy plans, explicit user input etc.

Durch die Sensoradaptoren werden die ermittelten Daten, die von den Ortungssystemen gewonnen werden, in Orte entsprechend der Struktur der Orte in den Ortsmengen und Ortsvektoren umgewandelt. Die Adaptoren legen abhängig von der Art des Sensors und dessen Einsatz (Ort der Installation, Zweck des Computerprogramms) fest, welche Referenzsysteme für die Abbildung der verwendeten Sensordaten geeignet sind. Sie wandeln die so gewonnenen Daten in Koordinatenwerte des entsprechenden Referenzsystems um. Liegen die Sensordaten direkt als Koordinaten eines Referenzsystems vor (beispielsweise bei GPS-Koordinaten oder symbolischen Orten), so kann direkt eine Abbildung auf einen Ort stattfinden.By means of the sensor adapters, the determined data, which are obtained by the location systems, are converted into locations corresponding to the structure of the locations in the locations and position vectors. The adapters depend on the type of sensor and its use (location of installation, purpose of the sensor) Computer program), which reference systems are suitable for mapping the sensor data used. They convert the data thus obtained into coordinate values of the corresponding reference system. If the sensor data are directly available as coordinates of a reference system (for example, GPS coordinates or symbolic locations), then an image can be directly taken on a location.

Die so gebildeten Orte werden - sofern geeignet - zu Ortsvektoren und zu Ortsmengen gruppiert. Über die Ursprünge der Referenzsysteme wird die Struktur der Orte, d.h. hierarchisch über- und untergeordnete Orte, gebildet. Die gewon-nenen Sensordaten werden ferner mithilfe der Eigenschaften der Sensoren - wie Genauigkeit - und der Eigenschaften der Referenzsysteme in Distanzangaben entsprechend dem Modell umgewandelt und über Orts- bzw. Vektorrelationen zu Positionierten Ortsmengen gruppiert.The places thus formed are - if appropriate - grouped into place vectors and local sets. About the origins of the reference systems, the structure of the locations, i. hierarchically superordinate and subordinate places, formed. The acquired sensor data is further transformed into the model according to the model using the properties of the sensors - such as accuracy - and the properties of the reference systems, and grouped by means of location or vector relations into Positioned Locations.

Beispiel: Ortung einer Person mittels Ultraschall in einem Raum an 3m horizonal von linker oberer Raumecke und 4m vertikal von linker oberer Raumecke. Genauigkeit der Ortung 10 cm. Gegenstandsreferenzsystem des Raumes liefert Stuhl an 3,5 m horizontal und 4 m vertikal. Daraus Ableitung des Ortes Stuhl mit Distanz 50 cm.Example: Location of a person using ultrasound in a room at 3m horizonal from the left upper corner of the room and 4m vertically from the left upper corner of the room. Accuracy of the location 10 cm. The object's reference system provides chair at 3.5 meters horizontally and 4 meters vertically. From this derivation of the place chair with distance 50 cm.

Für Ortsangaben, die in den sogenannten Informationsbedüfnissen enthalten sind, d.h. die Informationsbedürfnisse sind zu jedem einzelnen Nutzer oder Objekt in einer rechnergestützen Datei hinterlegt, in der zu jedem Ort das jeweilige Informationsbefümis abgespeichert ist, werden keine oder nur eine geringe Zahl von Sensoradaptoren benötigt, da diese üblicherweise in symbolischer Form oder in seltenen Fällen als physikalische Koordinaten vorliegen. Die Abbildung der Ortsmengen und -vektoren, Strukturen und Präpositionen erfolgt analog.For location information contained in the so-called informational requirements, i. the information needs are stored for each individual user or object in a computer-aided file, in each place the respective Informationsbefümis is stored, no or only a small number of sensor adapters are needed, as these usually in symbolic form or in rare cases as physical coordinates available. The mapping of the local sets and vectors, structures and prepositions takes place analogously.

Sind die durch Sensoren gewonnenen oder in den Informationsbedürfnissen festgelegten Ortsangaben entsprechend dem erfindungsgemäßen Verfahren abgebildet, können Operationen auf den Ortsangaben stattfinden. Diese Operationen ermöglichen einem Computerprogramm festzustellen, welche Informationen für einen Nutzer in Abhängigkeit von dessen Ort relevant sind. Hierzu sind in erster Linie die Ortsangaben in den Informationsbedürfnissen mit den durch Sensoren ermittelten Orten zu vergleichen. Zu diesem Zweck enthält das Modell Operationen wie isln(), equals(), howFarFrom() etc. Diese Operationen, die auf Orten durchgeführt werden, ermöglichen es festzustellen, ob Orte gleich sind, ob ein Ort in einem anderen enthalten ist oder wie weit Orte von einander entfernt sind.If the location data obtained by sensors or specified in the information requirements are mapped according to the method according to the invention, operations can take place on the location information. These operations allow a computer program to determine what information is for a computer program Users are relevant depending on their location. For this purpose, the locations in the information needs are primarily to be compared with the locations determined by sensors. For this purpose, the model includes operations such as isln (), equals (), howFarFrom (), etc. These operations performed on locations allow to determine if locations are the same, if one is contained in another, or how far Places are distant from each other.

Bei der Durchführung dieser Operationen werden Transformationsvorschriften verwendet, wenn die Orte sich auf unterschiedliche Referenzsysteme beziehen. Dabei wird zunächst eine geeignete Transformationsvorschrift ermittelt, um die Orte in ein einheitliches Referenzsystem zu überführen. Je nach Referenzsystem wird dabei eine einheitliche Repräsentation in Form von physikalischen Koordinaten oder durch Überführung der Koordinaten eines Ortes in Koordinaten, die zum Referenzsystem des anderen Ortes gehören, mittels hinterlegten Abbildungsdaten, bspw. "Gebäude XY" entspricht "Musterstr. 10, 12345 Muster-hausen, BRD" oder - vorschriften, bspw. Algorithmen zur Umwandlung von GPS-Daten nach dem UTM-System auf GPS-Daten nach dem WGS84-System, erreicht.In performing these operations, transformation rules are used when the locations refer to different reference systems. First, a suitable transformation rule is determined in order to convert the locations into a uniform reference system. Depending on the reference system, a uniform representation in the form of physical coordinates or by transferring the coordinates of a location into coordinates which belong to the reference system of the other location, by means of stored image data, for example. "Building XY" corresponds to "Musterstr. 10, 12345 Muster- hausen, BRD "or - regulations, eg algorithms for the conversion of GPS data according to the UTM system to GPS data according to the WGS84 system.

Auf Basis dieser einheitlichen Repräsentationsform lässt sich die Gleichheit zweier Orte direkt ermitteln. Da zwei Orte zwar ungleich sein, sich aber in Teilen überschneiden können, liefert das Verfahren als Ergebnis eines solchen Vergleichs eine Wahrscheinlichkeitsangabe, mit der solche Überschneidungen abgebildet werden. Die Distanz zwischen Orten wird dabei auf der Basis von physikalischen Koordinaten oder über Eigenschaften des jeweiligen Referenzsystems (bspw. Position und Abmessung von Räumen in einem Gebäude) in metrische oder zeitliche Abstände umgerechnet. Zeitliche Abstände beziehen sich auf eine bestimmte Fortbewegungsgeschwindigkeit.On the basis of this uniform form of representation, the equality of two places can be determined directly. Since two places may be unequal but may overlap in parts, as a result of such comparison, the method provides a probability indication that maps such overlaps. The distance between locations is converted into metric or temporal distances on the basis of physical coordinates or properties of the respective reference system (eg position and dimension of rooms in a building). Temporal distances refer to a certain speed of travel.

Weiterhin ermöglicht das dargestellte Verfahren, Ortsangaben, die von Sensoren erfasst wurden, mit Ortsangaben mit Informationsbedürfnissen von Nutzern, die entweder von den Nutzern explizit dem Computerprogramm mitgeteilt oder von diesem implizit ermittelt wurden, zu vergleichen. Das Ergebnis eines solchen Vergleichs ermöglicht es dem Computerprogramm festzustellen, ob ein Nutzer, der sich an einem bestimmten Ort befindet, einen Bedarf an Informationen hat und wenn dies der Fall ist, welche Informationen für den Nutzer unter Berücksichtigung seines Aufenthaltsortes relevant sind.Furthermore, the illustrated method, location information that has been detected by sensors, with locations with information needs of users that either explicitly communicated by the users of the computer program or by implicitly determined. The result of such a comparison enables the computer program to determine whether a user who is in a particular location has a need for information and, if so, which information is relevant to the user taking into account his or her whereabouts.

  1. A method for supplying a program-aided information system with specific location information, in which the information system provides at least one selection of certain location-dependent information on the basis of a person-specific or object-specific location which is detectable by a sensor,
    characterized by the combination of the following steps:
    - detection of positional data for a person-specific or object-specific location by a sensor,
    - transformation of said sensor-detected positional data into a location representing form by means of at least one sensor adaptor which establishes a reference system, within which said positional data can be spatially attributed, as well as being associated with a hierarchical structure,
    - combination of said location representing forms in a location set and/or in form of positional vectors in which said positional data of at least two locations are linked in a prescribed order, and/or
    - formation of location relations and/or positional vector relations between the locations, persons or objects within so-called positioned location sets, and
    - application of operations for determining the matching of locations as a basis of generating or providing location-dependent person-specific or object-specific information.
  2. The method according to claim 1,
    wherein said sensor detection of said positional data is conducted by means of technical locating systems.
  3. The method according to claim 1 or 2,
    wherein said sensor-detected positional data are transformed into a location representing form in the manner of coordinate values within said reference system.
  4. The method according to one of the claims 1 to 3,
    wherein information or characteristics of the locations associated with the respective locations representing forms of the sensor-detected locations are stored in the respective reference system.
  5. The method according to one of the claims 1 to 4,
    wherein said locations are associated with a hierarchical structure in the form of a tree structure.
  6. The method according to one of the claims 1 to 5,
    wherein said sensor-detected positional data are combined in a random order in said location set.
  7. The method according to one of the claims 1 to 6,
    wherein said positional vectors have at least two nodes at which a sensor-detected location is provided in a fixed order, and
    a connection is provided between two said nodes, along said connection information regarding the route between two locations being linked, if need be, in the form of an additional location set and/or an additional positional vector.
  8. The method according to one of the claims 2 to 7,
    wherein said location representing forms are associated with information regarding the precision, with which the positional data is acquired by said technical locating system, and are associated with information regarding the distances within the reference system.
  9. The method according to claim 8,
    wherein said positional data associated with information regarding the precision and the distances within said location relations and/or said positional vector relations are grouped in said positioned location sets and are associated with so-called prepositions, which describe a spatial relative position between said locations and persons, respectively between said locations and objects, numerically and/or semantically.
  10. The method according to one of the claims 1 to 9,
    wherein the information requests are stored in the form of computer-aided data, and on the basis of said operations it is determined whether the positional data contained in said information requests match the positional data acquired by the position sensors.
  11. The method according to claim 10,
    wherein said operations check whether the location representing forms acquired from the sensor data and said locations in said information requests match or whether there is an inclusion relationship, and
    matching or numerical information regarding the spatial distance of said location representing forms acquired from the sensor data and said respective location-dependent information requests is determined.
