Description

Input of geodesics in a navigation device

Technical area

The invention relates to a method for entering geodesics in a navigation device, wherein the geodesics are related to an indication of a location that is detectable by a user. The invention also relates to a device suitable for carrying out the method. Furthermore, the invention relates to a device for providing and / or reproducing an indication of a location that can be detected by a user.

Background of the invention

On the way, for example, passengers of vehicles or pedestrians are provided with a large amount of information. These are, for example, acoustically detectable information that is provided via the broadcast, for example, or visually detectable information provided by an information carrier, such as a poster, which is arranged on a street. The information provided often includes data intended for further use by the recipient of the information. In particular, the information may include location information, specifying, for example, the location of an event to which the information relates, or the address of a restaurant to which the information relates. This information can be entered by the information receiver in particular into a navigation device in order to navigate to the relevant location.

In this case, there is the problem that the location information intended for further use can often not be noted on the way, since the information recipient does not carry utensils that can be used for quotation, or the Listing the location information is associated with an effort that the information recipient can not take on, for example, because he is busy with the driving of a vehicle, or would not take in the appropriate situation. The information recipient is therefore often reliant on keeping the information in his memory in order to use it at a later date. If the information recipient forgets the location details, however, these are often no longer or only with great effort to regain. This is disadvantageous on the one hand for the recipient of the information and on the other hand for the author of the place information, since these usually do not achieve their purpose if they are not available for later use. Thus, for example, an advertisement for a particular event or a specific device only achieves its purpose if the location information contained in the event or the address of the device is available to the information recipient after the information has been recorded for further use.

Presentation of the invention

It is therefore an object of the present invention to make available to a user who perceives an indication of a location, the location information in a manner that is as simple as possible for the user for further use in a navigation device.

According to the invention this object is achieved by a method according to claim 1, by a device according to claim 19 and by a device according to claim 21.

Accordingly, it is provided that a method of the type mentioned above is performed so that - in conjunction with the indication of the location electronically detectable additional data are provided, which contain the geodesics, - the additional data are detected by a receiving device, and - The geodetics of the navigation device contained in the additional data can be made available on the basis of an operating action performed on the receiving device.

Furthermore, a device for inputting geodesics into a navigation device is provided, wherein the geodesics are related to an indication of a location that can be detected by a user. The device comprises a receiving device, which is designed to detect geodata-containing additional data provided in connection with the indication of the location, and an operating device, by means of which the user can execute an operating action, the receiving device being designed for this purpose to make the geodata contained in the additional data available to the navigation device on the basis of the operating action.

In addition, an apparatus for providing and / or reproducing an indication of a location that is detectable by a user is provided. The device comprises a device for providing additional data, which contain geodesics, which are related to the indication of the location, and can be detected by means of a receiving device connectable to a navigation device.

The invention thus includes the idea that geodata comprehensive additional data that can be detected by a receiving device, in addition to a specified by the user indication of a location are provided. After their detection in the receiving device, the geodesics can be entered into a navigation device by an operator action of the user. In the navigation device, route guidance information can then be determined on the basis of the geodesics, by means of which the user is guided to the location.

The additional data is preferably provided separately from the location that can be detected by the user, ie, in particular via a separate channel. The invention has the advantage that the geodesics can be used in a simple manner, since the user can initiate the further use of the geodesics on the basis of a simple operating action on a receiving device. This is connected to the user with a very low cost and only a small amount of distraction and can therefore happen especially when traveling, for example while driving a vehicle. The invention thus offers advantages for the user of the receiving device. At the same time, the usefulness of the location information for their author is increased, since the simplifications achieved by the invention result in increasing the likelihood that the user will continue to use the location information or the geodesics relating to the location information.

An embodiment of the method and the devices provides that the additional data are at least partially displayed on the receiving device, wherein the operating action during the display of the additional data at the receiving device is executable.

During the display of the additional data on the display device, the user can decide whether he wants to continue to use the additional data and in particular the geodesics contained before he possibly performs the operating action. Furthermore, it is clarified by the display of the additional data to soft additional data relates to the operator action to be performed.

In a further embodiment of the method and the devices, it is provided that the additional data is displayed on the receiving device for a predetermined period of time substantially beginning with the acquisition of the additional data.

In this embodiment, the user advantageously has the possibility during the predetermined period of time to carry out the operating action and thus to change the direction. use of the additional data and in particular of the geodesists. After expiration of the time period, the additional data is preferably discarded, so that no special operating action is required for this purpose. This further increases the comfort for the user. Furthermore, a distraction that would be associated with such an operating action is avoided.

It may also be the case that additional data associated with a plurality of location indications occurs at short intervals, i. be detected simultaneously or in small, nonzero time intervals, by means of the receiving device.

In order to allow the user to select the additional data of location information of interest from the plurality of additional data, it is provided in an embodiment of the devices and the method that additional information associated with a plurality of location information, which has been detected by the receiving device within a small time interval, is within a list at the receiving device, wherein the user can select an entry of the list to which the operating action relates.

An alternative embodiment of the devices and of the method is characterized in that additional data associated with a plurality of location information which have been detected in the receiving device at a small time interval are displayed alternately at the receiving device.

The operating action with regard to additional data that is associated with a location that interests the user can also be carried out in this embodiment during the display of this additional data. The advantage of this embodiment is, in particular, that the user does not have to make a selection of the additional data from a list that would distract him, for example, from driving a motor vehicle. Therefore, this embodiment is particularly suitable for use of the receiving device in a motor vehicle. Moreover, an embodiment of the method and the apparatuses includes that the indication of the location is part of a broadcast program transmitted by a broadcasting station, wherein the additional data is sent in addition to the broadcasting program.

In this embodiment, the additional data is advantageously provided in addition to a broadcast program, which may be a TV or a radio program. In particular, the broadcast program may, for example, be a TV or radio contribution in which the location is mentioned, or an advertising broadcast which includes a mention of the location or a device located in the location. The embodiment makes it possible to make available to the user geodesics of locations which are related to the radio program on the basis of additional data. The additional data can be sent by the broadcaster or another station.

An associated embodiment of the method and the devices is characterized in that the additional data are sent substantially simultaneously with a mention of the location within the broadcast program.

In this embodiment, a synchronization between the content of the broadcast program and the provision of additional data is advantageously provided, which is characterized in that the additional data is essentially sent when the name of the location in the broadcast program takes place. This has the advantage that the additional data is provided to the user substantially at the time in which he captures the location within the broadcast program. This makes it particularly easy for the user to establish the relationship between the additional data and the location recorded via the broadcast. In addition, a development of the method and the devices that the receiving device is part of a radio receiver for receiving the broadcast program.

The advantage of this development is, in particular, that the radio receiver and the receiving device are an integrated device, so that the user does not need any additional device in order to receive the additional data provided in addition to the radio program.

A further embodiment of the method and the devices provides that the indication of the location is provided by an information carrier, wherein a transmitting device is arranged in spatial proximity to the information carrier, which transmits the additional data to the receiving device.

This embodiment has the advantage that additional data is made available in addition to location information provided by an information carrier. In this way, the user can in particular reuse the geodesics, which are related to a location indicated on the information carrier, in a very simple manner. The term information carrier is to be understood in the context of the invention in its broadest meaning. For example, it includes advertisements and advertising posters, information and advertising columns. In particular, the information carrier can also be embodied as a device for reproducing audio and / or video data.

In an associated embodiment of the method and the devices, it is provided that the transmission of the additional data takes place on the basis of a signal which is selected from the group comprising a radio signal, an acoustic signal and an optical signal.

Advantageously, the said types of signals allow a wireless transmission of the additional data from the transmitting device to the receiving device. Another advantage is that common portable terminals, such as For example, mobile phones, PDAs (PDA: Persona Data Assistant) or laptops, often already have interfaces for receiving one or more types of the aforementioned signals and therefore can be used without equipment with additional hardware as a receiving device according to the invention. When using radio signals, the additional data can be provided, for example, via Bluetooth or WLAN (Wireless Local Area Network). For optical data transmission, for example, offer infrared (IR) signals.

A further embodiment of the method and the devices is characterized in that the indication of the location is provided by an information carrier, wherein the information carrier has an electronically detectable marking, in particular a barcode, which contains the additional data and is detected by the receiving device.

The advantage of this embodiment is, above all, that the information carrier does not need to have any electronic transmitting device in order to provide the additional data, but remains purely passive. This avoids, in particular, the necessity of providing a power supply which is required, for example, when using a transmitting device.

Furthermore, a development of the method and the devices is characterized in that the additional data are encrypted and can be decrypted with a decryption key stored in the receiving device.

Advantageously, the additional data in this development can only be used by a user if this or its receiving device has a decryption key for decrypting the provided additional data. In this way it can be avoided that the additional data can be received and used by unauthorized users. An embodiment of the method and the devices also includes that the receiving device and / or the navigation device are installed in a motor vehicle.

Advantageously, the user can receive the additional data in this embodiment, while he is traveling with a motor vehicle. Another advantage is that the devices often present in motor vehicles, such as navigation devices and / or radio receivers, can be used within the scope of the invention.

A further embodiment of the method and the devices provides that the receiving device and / or the navigation device are components of a portable terminal of the user, in particular a mobile telephone, a personal data assistant, a laptop or the like.

This refinement also advantageously allows the user to receive the additional data while he is on the move. He wears the aforementioned devices often anyway with him. An additional device is therefore generally not required to receive the additional data. In addition, the aforementioned terminals, as already mentioned, often already have interfaces for receiving signal types, which can also be used to provide the additional data. These existing interfaces can be used advantageously within the scope of the invention.

In particular, if the receiving device and the navigation device are integrated in a single device, the additional data or the geodesics contained therein can be transmitted directly to the navigation device due to the operator action.

Likewise, however, in one embodiment of the method and the devices, it is provided that the additional data due to the operating action in the Receiving device stored and transmitted at a later date to the navigation device.

This embodiment is particularly suitable if there is no permanent connection between the receiving device and the navigation device and makes it possible to first capture the additional data by means of the receiving device and then to transmit it to the navigation device at a later time. For example, the user can capture the additional data using his PDA while he is on the road, and then transmit it to the navigation device of his motor vehicle in order to navigate to the location specified by the geodesics contained in the additional data.

With regard to the geodesics, an embodiment of the method and the devices provides that the geodesics comprise geocoordinates and / or an address of the location.

As a result, a location can be specified in a simple manner. From the geo-coordinates and / or the address of the place, the user can, however, usually not deduce which place it is. If, for example, the geo-coordinates and / or the address of a restaurant are specified, the user usually does not know which restaurant they are referring to. However, this information is useful for the future reuse of geodesists.

Therefore, in one embodiment of the method and apparatus, it is provided that the additional data include a name or description of the location.

Furthermore, an embodiment of the method and of the devices is characterized in that an association between the name or description of the location and the geodesics is stored in the navigation device where the route guidance information is determined by calling the name.

In this embodiment, the user can easily start the route guidance to the location specified by the geodesics contained in the additional data by selecting the name or description of the location assigned to the geodesics, which is generally available to the user more meaningful than the geodesics themselves. This further enhances the user-friendliness.

In addition to the method and the devices, a navigation system is also provided. This comprises a device for inputting geodesics into a navigation device, which is configured as described above, and a navigation device, which has a destination guide device, which is designed to determine route guidance information in dependence on the geodesics.

The navigation system may advantageously be implemented as an integrated system, in particular as a radio navigation system of a motor vehicle as a portable terminal, such as a mobile phone, a PDA or a laptop, which has a navigation device. Likewise, however, it can also be provided that the device for inputting the geodesics and the navigation device are each designed as an independent device.

In the device for providing and / or reproducing an indication of a location which can be detected by a user, different embodiments of the invention already mentioned above may in particular be a broadcast transmitter or an information carrier of the type described above. A system is further provided which comprises the device for providing and / or reproducing an indication of a location as well as the device previously presented for entering geodesics into a navigation device and / or the navigation system.

The above and other aspects of the invention will become apparent from the embodiments which will be described below with reference to the figures.

1 shows a schematic illustration of a navigation device 101. The navigation device 101 comprises a position-determining device 102, with which a current position of the navigation device 101 can be detected. In one embodiment, the position determination takes place in a satellite-based manner in a manner known to the person skilled in the art, using the signals of a plurality of satellites which are received in the navigation device 101. In this case, for example, the GPS (Global Positioning System) known per se or another satellite navigation system can be used.

Furthermore, the navigation device 101 comprises a destination guidance device 103 in which, on the basis of the current position of the navigation device 101, guidance information is determined which guides a user of the navigation device 101 to a predetermined navigation destination. The route guidance information is preferably determined using area data stored in a database 104 of the navigation device 101.

The area data includes digitized map data of a geographical area, preferably including a road network within the geographical area, and addresses of land or buildings in the geographical area. The map data and the position of the navigation device 101 determined in the position determination device 102 relate to a geodetic reference system in which each point of the geographical area is specified by a geo-coordinate. An example of such a reference system is WGS84 commonly used in the GPS (World Geodetic System 1984).

In one embodiment, the navigation device 101 also includes a memory 111, in which so-called points of interest can be stored. These include the geo-coordinates or the address of specific locations stored in the memory 111 along with a description of the location. The name includes, for example, a name of a person to whom the stored address is assigned, or another name of the place, such as the name of a restaurant. Points of interest can in particular be created by the user of the navigation device 101 in order to store the geo-coordinates or addresses of locations which are of interest to the user. By calling up a POI stored in the memory 111, the geo-coordinates or the adress information are adopted as the navigation destination, and in the route guidance device 103, a route to this navigation destination is determined.

Within the route guidance device 103, a route is preferably calculated on which the user of the navigation device 101 reaches a navigation destination based on the current position via the road network of the geographical area. Based on the route guidance information, the user is then instructed to follow the calculated route. The guidance information includes directional indications that preferably indicate in which direction the user has to turn to intersections in order to follow the calculated route. The directional hints may be output on a display device or in the form of voice messages. Furthermore, using the map data, a map can also be displayed on the display device, in which, for example, the current position of the navigation device 101 and the calculated route are displayed.

The navigation targets are provided to the route guidance device 103 in the context of the present invention by means of a reception device 105 which is permanently or temporarily connected to the navigation device 101. The receiving device 105 has a receiver 106, with which in particular geodesics comprehensive additional data can be received in the receiving device 105. Furthermore, a decoding device 112 is provided, which reads out the additional data from a received by means of the receiving device 105 signal. In addition, the receiving device 105 has a display device 107, which is designed, for example, as a display, and via an operating device 108, by means of which the user can operate the receiving device 105. The operator 108 includes, for example, switches, one or more buttons, or a keyboard for performing operator actions. Furthermore, the receiving device 105 has a processor unit 109 for controlling the functions of the receiving device 105. Furthermore, the receiving device 105 preferably comprises a memory device 110.

The navigation device 101 and the receiving device 105 are preferably integrated in one device. This may be, for example, a radio navigation system of a motor vehicle or a portable terminal, such as a mobile phone, a PDA (Personal Data Assistant), a laptop or the like. The mentioned devices are currently available! already on the aforementioned components that are included in the receiving device 105. Therefore, the devices only need to be equipped with software executable on the processor unit 109 in order to receive geodesics and make them available to the route guidance device 103.

In addition, some of the devices already mentioned have a navigation device 105 that can be used within the scope of the present invention. Likewise, however, provision may also be made for the navigation device 101 and the receiving device 105 to be separate devices, between which a data connection can be established via a suitable interface. For example, it may be provided that the receiving device 105 is a portable terminal in which the additional data is first received and stored. From the terminal, the additional data or the geodesics contained then be transmitted via an interface to a navigation device 101.

The geodesics contained in the additional data comprise the indication of an event, which can be used in the route guidance device 103 of the navigation device 101 in order to determine a route to the location specified on the basis of the geodesics. The geodesists therefore preferably include an address of the location, which contains, for example, an indication of a street, a house number, a city and optionally a postal code of the location concerned, and / or geo coordinates of the location.

The additional data are related to information which the user of the receiving device 105 acoustically and / or visually perceives. In one embodiment, illustrated schematically in Figure 2, this information is a broadcast program such as a broadcast report designating an address, or an advertisement broadcasting a location or address becomes. The receiving device 105 is preferably integrated in this embodiment in a radio receiver 201, with which the broadcast program is received and reproduced. As such devices, in particular, the aforementioned devices, such as radio navigation systems of motor vehicles, mobile phones, PDAs or laptops, in particular, are used, as they are often designed for a radio reception.

The broadcast program can be both a radio and a TV program. Accordingly, the radio receiver 201 includes a radio and / or TV receiver. In this case, the additional data are transmitted by a radio transmitter 202, for example, as an additional signal in addition to the actual broadcast signal containing the broadcast program. Thus, in this case, the receiving unit of the radio receiver 201, by means of which the broadcast program is received in the radio receiver 201, can be used as a receiver 106 of the receiving device 105. For the transmission of the additional data, in the case of radio, for example, a signal containing the additional data can be modulated onto a subcarrier. This procedure is known, for example, from the RDS (Radio Data System), in which a subcarrier with a frequency of 57 kHz is used to transmit additional information.

Preferably, the additional data in time proximity to the mention of the location or the address in the broadcast is broadcast by the broadcasting station 202, that is, the transmission of the overhead data is synchronized with the broadcasting program. For example, if a broadcast refers to an event taking place in a particular location, additional data comprising the geodesics of that location will be broadcast by the broadcaster 202 in close proximity to the mention, for example, during the broadcast of the cue. If an advertisement, in particular a radio commercial, contains an indication of a location, then the additional data may be transmitted, for example, at the beginning or during the broadcast of the commercial by the broadcaster 202.

In addition to the geodesics, the additional data preferably comprise information about the reference of the geodesics, which in particular contains a description or description of the location represented by the geodesics. For example, together with the geodesists who describe the location of an event, a name or description of the event and / or a name of the venue will be sent. For example, if an advertisement includes an indication of a particular restaurant, then a name and / or a brief description of the restaurant will be sent along with the geodesists representing the address of the restaurant.

In the receiving device 105, the additional data is received by the receiver 106 and read in by means of the decoder 112. Then the processor unit 109 controls the receiving device 105 such that the additional data is displayed on the display device 107. The representation of the data on the display device 107 is preferably carried out for a predetermined period of time, which is for example several seconds or several minutes. During the display of the additional data, the user of the receiving device 105 has the option of selecting an option from several options for further processing of the additional data. This is done by means of an operator action, which is carried out by means of the operating device 108 of the receiving device 105. Possible options for processing the additional data include, for example, storing, deleting, taking over the geodesics directly as a navigation destination and editing the additional data.

If the option "Save" is selected, the received additional data, including the geodesics, are stored in the storage device 110 of the receiving device 105 for further use. At a later time, the additional data can then be transmitted from the receiving device 105 to the navigation device 101. This is particularly advantageous if only a temporary data connection exists between the receiving device 105 and the navigation device 101. After the transmission of the additional data to the navigation device 101, a POI is preferably generated in the memory 111 of the navigation device 101. The point of interest includes the geodesists, ie the address and / or the geodesic of the place concerned as well as its name or description. To navigate using the navigation device 101 to the relevant location, the user calls the corresponding point of interest, which is then adopted as the navigation destination. If there is a permanent data connection between the receiving device 105 and the navigation device 101, when selecting the "Save" option, a POI is directly generated in the memory 111 of the navigation device 101 on the basis of the additional data. By selecting the "Edit" option, the user can edit the additional data. In particular, the user can change the name or description of the place to which the geodesics are assigned. In this way, the user can enter, for example, a name of the place, which he considers more appropriate or more meaningful than the name contained in the additional data. After the processing, the additional data are then stored in the memory device 110 of the receiving device 105 or in the memory 111 of the navigation device 101 in the manner described above on the basis of a corresponding operator action of the user.

If the user selects the option "adopt as navigation target", then the geodesics contained in the additional data are transferred directly to the route guidance device 103 of the navigation device 101 in order to determine a route to the location specified on the basis of the geodesics. As a result, the user can navigate in a simple manner immediately after the receipt of the additional data using the navigation device 101 to the relevant location. Of course, the option is only available if the receiving device 105 is connected to the navigation device 101.

If the option "Delete" is selected, the received additional data will be discarded. This preferably also happens when the time period provided for the display of the additional data has expired.

If several locations are provided in the radio program at short intervals or, as is possible in the case of a TV program, at the same time, then the time intervals in which the associated additional data are displayed at the receiving device and in which the user intersects Operating action to reuse the additional data can make.

In this case, the receiving device 105 can be configured such that the designations and / or the geodesics are displayed on the display device 107. several locations are displayed in a list. By means of the operating device 108, the user can go through the list and select an entry of the list in order to carry out the further use of this entry in accordance with one of the options presented above.

Likewise, it can be provided that is periodically switched between representations of the various location information associated additional data. The additional data associated with a specific location are displayed several times for a predetermined period in alternation with further additional data. During the display of the additional data, the user can perform one of the aforementioned operator actions in order to make the geodesics or the additional data available for further use in the navigation device 101. The switching between the representation of the various additional data has the advantage that no actuation of the operating device 108 is required to select the additional data associated with a location. This embodiment is therefore particularly suitable for use within a radio navigation system of a motor vehicle, since the driver is not distracted by the selection of additional data from a list.

In further embodiments, which are illustrated schematically with reference to FIGS. 3 and 4, the additional data is provided by an information carrier 301 or a transmitter 302 arranged in the region of the information carrier 301. In principle, all media for reproducing acoustically and / or visually detectable information come into consideration as information carriers 301. In one embodiment, the information carrier 301 is located in an area accessible to the public, so that the user of the receiving device 105 perceives this when he is on the move. Examples of such information carriers 301 are advertising media, such as posters or neon signs, information pillars or advertising columns and / or devices for reproducing videos, which comprise, for example, means for the projection of video data or a screen for the reproduction of video data. The additional data provided, in particular in particular, the geodesics contained in the additional data are related to the information reproduced by the information carrier 301. For example, the information carrier 301 may represent an advertisement for a restaurant, and the supplemental data may include a name or description of the restaurant, as well as geodesists indicating the location where the restaurant is located.

In one of the aforementioned embodiments, which is described with reference to the schematic representation in FIG. 3, a transmission device 302 is arranged in the region of the information carrier 301, which transmits the additional data by radio. In this case, radio standards known to the person skilled in the art, such as e.g. Bluetooth, WLAN or the like, are used. The transmission power of the transmission device 302 is preferably selected such that the signals 303 which contain the additional data can be received up to a distance in which the information carrier 301 can typically still be perceived. As a rule, these can be, for example, a few meters or a few tens of meters; larger transmission ranges are, however, also conceivable with information carriers 301 which can be perceived from a greater distance. The signal 303 containing the additional data is a radio signal. This is preferably emitted at regular intervals of, for example, a second or a few seconds. The signals 303 emitted by the transmitting device 302 are received by the receiver 106 of the receiving device 105 when it is located in the transmitting region of the transmitting device 302. The receiver 106 is formed in this embodiment as a radio antenna.

A further embodiment provides that acoustic signals 303, ie sound waves, are used to transmit the additional data which are transmitted by a transmitting device 302 designed as a loudspeaker and contain the additional data. The acoustic signals 303 preferably have a frequency which is above the frequency range of the human ear is perceptible. The human ear is capable of perceiving acoustic signals 303 at frequencies up to about 20 kHz. The acoustic signal 303, which contains the additional data, therefore has a frequency that is sufficiently high so that it can not be perceived by the human ear. For example, the frequency is greater than 25 kHz. The acoustic signal 303 is also transmitted by the transmitting device 302 at regular intervals, for example, one second or a few seconds. The receiver 106 of the receiving device 105 is formed in this embodiment as a microphone which is capable of receiving the acoustic signals 303. The signals 303 are received when the receiving device 105 is located at a sufficiently short distance from the information carrier 301 and the acoustic signals 303 are not shielded from the receiver 106.

If the information carrier 301 is an electronic device, such as a neon sign or a device for reproducing video data, it can be provided that the transmission devices 302 used in the previously illustrated embodiments are integrated into the device. Likewise, however, the transmitting devices 302 can also be arranged at a spatial distance from the information carrier 301 and be designed as a stand-alone device. If the information carrier 301 does not comprise an electronic device, as is generally the case, for example, with posters or advertising columns, then the transmitting device 302 is designed as an independent device and arranged in the region of the information carrier 301.

In addition, provision may also be made for the additional data to be transmitted via an optical connection from the transmitting device 302 arranged on the information carrier 301 to the receiving device 105. In particular, an IR connection is used to transmit a signal 303 containing the additional data. For this purpose, the transmitting device 302 is designed as an IR transmitter and the receiver 106 of the receiving device. device 105 as an IR receiver. The additional data are also sent in this case at regular intervals by the transmitting device 302 and can be received by the receiver 106 of the receiving device 105 when the user has the receiver 106 aligned accordingly. As a rule, for this purpose, the user must approach the receiving device 105 or the receiver 106 of the transmitting device 302 to a small distance, so that this embodiment is more suitable for use with portable receiving devices 105.

A further possibility for providing the additional data, which is illustrated schematically in FIG. 4, is to attach to the information carrier 301 an electronically detectable marking 401, such as a one- or two-dimensional barcode, wherein the additional data are coded in the marking and the can be read by means of the receiving device 105. The receiver 106 of the receiving device 105 is designed for this purpose as a reading unit which is capable of evaluating the electronically detectable marking 401. In order to detect the marking 401, the user must usually bring the receiving device 105 or the receiver 106 into close proximity to the marking 401. Therefore, this embodiment is also more suitable when using portable receiving devices 105. In addition, the user has a lower level of comfort than, for example, when transmitting the additional data by radio, via an optical connection or by means of acoustic signals. An advantage of the use of electronically detectable markings 401, however, is that no electronic transmitting device 302 has to be arranged on the information carrier 301 and therefore a power supply can be dispensed with.

Of course, the aforementioned embodiments may be combined, and the receiving means 105 may be equipped with a plurality of receivers 106, each adapted to receive a particular type of signal 303. This may result in different information sluggish 301 different methods for the transmission of additional data are used. For example, the receiving device 105 may have both a receiver 106 for receiving radio signals 303 containing the additional data and a reading unit for reading in markers 401 containing the additional data so that additional data provided by radio as well as by means of a marking 401 can be transmitted by the receiving device 105 can be detected.

Even if the additional data are provided by an information carrier 301 or a transmitting device 302 arranged in the region of the information carrier 301, it is provided, as in the provision of broadcast signals which contain the additional data, that the additional data is displayed on the display device 107 of the receiving device 105 after they have been detected by the receiving device 105. The user then has the option of controlling the further use of the additional data in the manner already described above. In particular, some or all of the described options "Save", "Delete", "Apply as destination" and "Edit" are also available.

Even if the additional data relate to location information that is provided by means of an information carrier 301, the case may occur that additional data relating to a plurality of location details is detected simultaneously or in a short time sequence in the receiving device 105, for example if an information carrier 301 comprises a plurality of location information and / or if a plurality of information carriers 301 are located in the vicinity of the reception device 105. If additional data relating to a plurality of location details are provided by one or more information carriers 301 at the same time or in a short time sequence, then, as already described above, a list with the additional data can be displayed at the receiving device 105, and the user can make individual entries Select from the list to reuse these entries according to one of the options presented above. It can also be provided As described above, the representation of the names and / or geodetics assigned to the various location details changes periodically, with the user being able to initiate the further use of additional data of interest if these additional data are displayed on the reception device 105.

Furthermore, it can be provided that the provided additional data is encrypted. A decryption of the additional data takes place here in the decoding device 112 of the receiving device 105 with the aid of a decryption key stored in the receiving device 105. This prevents the additional data from being collected and used by unauthorized persons. The decryption key can be introduced into a secure memory area when authorized receiving devices 105 are manufactured, so that the decryption key can not be read out of the receiving device 105 in a misguided manner. Likewise, the key can later be provided by a provider and introduced into the receiving device 105.
