Description

Method for operating a mobile electrical device

The invention relates to a method for operating a mobile electrical see device according to the preamble of claim 1.

Known mobile electrical devices are configured to record an image of a part of the optical environment by means of an optical recording device, to superimpose the optical image with further image contents, in particular virtual image contents to destinations from a target database, and to form the resulting image of a part of the environment of the image mobile electrical device output by means of an output device.

In the superimposition of the virtual image content with the recording of the recording device generic devices are set up to arrange the virtual image content on the image of the part of the environment of the mobile electrical device that this with a reference to a specific position or place in the recording of inserted or superimposed on optical recording device. In other words, this means that in known mobile electrical devices and methods for their operation the direction of an optical recording device by means of corresponding sensors, in particular

| Confirmation copy | determined by means of a compass, as well as the current geographical position of the mobile electrical device and lying in the respective identified direction targets are selected at a certain distance from the current geographical position and superimposed on these targets associated graphical symbols with the recording of the recording device and be output on an output device.

Corresponding known methods are sometimes attributed to the generic term of augmented reality.

A disadvantage of the method of the prior art is that mobile electronic devices over a steadily growing number of

As a result, the situation arises that in a certain situation, that is, when determining a current geographical position and a spatial orientation of the recording device of the mobile device, already at a very small spatial distance from the device a variety of potentially presentable goals exists. This in turn gives rise to disadvantages which, on the one hand, adversely affect the functionality of the corresponding method and, on the other hand, the operability of the mobile electronic device.

In the case of a large number of targets, which are to be superimposed by means of assigned virtual image contents with the recording of the recording device and output on the output device, reduced clarity may occur, which in the worst case results in the user of the combined output of the recording

Recording device and the virtual image content additional information is difficult or impossible. This may in particular concern the selection of goals.

In an attempt to reduce the number of targets to be overlaid with the recording device via virtual image content in To maintain a favorable for the presentation dimensions, it also comes in the known from the prior art methods to disadvantages that significantly limit the functionality or the user benefits of the corresponding methods. A first known way of reducing the number of targets is to limit the distance by taking into account, based on the current geographical position of the device, targets for the generation of a combined graphical representation. However, this leads to the disadvantage that the currently generated and output geographic representation includes in doubt only targets that are in close proximity to the current position of the device, and thus without the corresponding method and thus without using the mobile electronic device the user is noticeable.

An alternative, well-known approach to reducing the number of targets for generating and outputting corresponding graphical representations is to give limited consideration to existing or available target databases. However, this leads to the disadvantageous development that the generated and output graphical representations are adapted only to a very limited extent to the individual situation of the user and are therefore of little use for him or not at all.

Starting from this prior art, it is therefore an object of the present invention to propose a method for operating a mobile, electrical device, which overcomes the disadvantages of the prior art and in particular in consideration of a large amount of potential targets or target databases in a position to generate and output a graphical display which is both clear and informative for the user, comprising a recording of an optical recording device and virtual image contents associated with individual destinations. The object is achieved by a method according to the teaching of claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims. The method according to the invention is based on the basic idea that in the graphical representation, which is generated from the inclusion of a recording device and graphic symbols of targets in a certain geographical area in the vicinity of the current position of the device, respectively available in the field - Which targets from different target databases are subjected to a selection process or a filtering, which is done on the basis of at least one relevance criterion stored in the electrical device and that moreover adapted the respective graphical symbols that are used to generate a graphical representation based on at least one adaptation criterion become.

It is provided that a mobile electrical device operated by the method according to the invention comprises at least one position determination unit with which the current position of the device can be determined, for example a GPS unit. It is further provided that the device comprises at least one target database, for example a POI database, in which target-specific information with the geographical positions of the respective target is stored. It is further provided that the device comprises at least one optical recording device, at least one direction determination unit with which the spatial orientation of the optical recording device can be determined, at least one optical output device and at least one input unit with which operator inputs can be registered. The recording device may be, for example, a digital image sensor in conjunction with a corresponding optics. The direction determination unit can also be, for example, an electric compass or a gyrosensor act. The output device and the input unit can be designed, for example, as a combination in the form of a multi-touch display. In addition, it is provided that the device has a memory unit in which a Zielsuchradius can be set and stored.

For the method, it is provided in a first method step that the determination of the current position, the determination of the spatial orientation of the optical recording device and the reading of the target search radius from the memory unit. In a second method step, the determination of at least one geographical area is provided depending on the orientation of the recording device and / or the current position and the target search radius.

In this case, the geographical area in the horizontal direction can be limited by the viewing angle which is defined by the image detail given by the recording device.

In a third method step, the filtering of at least one destination from at least one destination database takes place based on the geographical position of the destinations relative to the at least one specific geographical area. Thus, a selection of targets is initially generated, which can in principle be integrated into the recording of the recording device in the current spatial orientation of the recording device by icons or virtual image content or superimposed with this.

In a further method step, there is a second filtering of the previously determined goals, whereby the filtering out of at least one of the geographically filtered out targets is based on the relevance of the filtered out targets for the user on the basis of at least one

Relevance criterion. In a subsequent method step, it is provided that graphic symbols are generated and adapted to the filtered-out targets, the adaptation taking place on the basis of at least one adaptation criterion. Alternatively to the generation of graphic symbols can also be provided that the graphical symbols are already held in the device or can be retrieved from the device from an external source by means of data transmission. In a first method step, the generation of a graphical representation comprising at least one optical image of the recording device and at least one geographical symbol of a target takes place, as well as the output of the graphical representation on the output device of the device. In summary, the method according to the invention thus produces an augmented reality representation of at least part of the environment of the mobile device, which essentially maps the part of the environment which is recorded by the recording device and in which graphical symbols of destinations are contained in a geographic area defined by the current location and spatial orientation of the host, and that the destinations also have increased relevance to the user. In addition, it is possible to additionally adjust the graphical symbols of the targets in order to generate or output an optimized graphical representation.

In principle, any database in which a respective entry or data record contains not only information which can serve to specify the geographical position but further information which can be usefully assigned to the respective destination is included as the target database in the sense of the method according to the invention , An example of corresponding databases is a contact database in which various persons or institutions have a postal address and further information, such as the name, for example. Another destination database may be, for example, a point of interest (POI) database known from navigation devices. In addition, the mobile device can also Target databases include or access target databases where the geographical position is not constant in time but rather variable in time, and thus represents a target database of moving targets. The moving targets or the information in addition to the variable position information may be, for example, persons, vehicles or the like. Access to external databases can be done by means of a known data transmission device with a corresponding server.

According to a first embodiment of the method, it is provided that the relevance of the destinations of a target database is determined by means of relevance criteria. The advantage of separate relevance criteria for different target databases lies in the fact that in many cases the type of data records or data records stored in the respective target database is. Goals provide or demand different possibilities or requirements for relevance assessment. For example, it may be provided to determine the relevance of goals superordinate by their temporal relevance. As a result, when filtering out targets of a target database with mobile targets, a relevance criterion can be derived which evaluates the relevance according to the age of the last position specification of the respective target. When filtering out lines from a special destination database, the relevance criterion can be configured such that the relevance is determined on the basis of a match of the current time with the opening times of the particular POI. When filtering targets from a contact database, the relevance criterion relevance can be assessed based on the frequency and / or the last time the respective contacts are used for a call and / or a message.

However, it may also be the case that the structure or type of information stored next to the geographical locations in different target databases is similar or at least similar. Conceivable are target databases in the manner of a POI database. For example, it is possible for the mobile electronic device to have or access different POI databases, with the individual destination databases comprising destinations of different categories. Thus, for example, a separate target database for culinary goals for shopping, for attractions or the like may be provided, in addition to the respective position information, such as opening hours and offer the respective destination, can be stored in the target database. In this case, an advantageous embodiment provides that the relevance of the goals of more than one target database can be determined by means of relevance criteria. For example, for all target databases whose datasets include opening times, a cross-database relevance criterion can exist in the match between the opening time and the current time of day.

In a further advantageous embodiment of the method according to the invention, it is provided that relevance weighting of different target databases can take place by means of at least one relevance criterion. This is particularly advantageous if a large number of target databases are searched or destinations are filtered out of the corresponding target databases. In order to avoid tedious and computationally executing a plurality of relevance scores for the most diverse goals, a relevance weighting of different target databases can be used effectively. In this case, provision may be made, for example, for target databases to be subdivided into relevance groupings, whereby instead of a relevance assessment of the individual target, a relevance evaluation based on the affiliation of the target to the respective target database takes place.

Furthermore, it is provided in a desirable embodiment of the method that relevance criteria are at least partially independent of each other, whereby more than one independent of each other Relevance determination can take place. For example, it can be provided that a temporal relevance based on a corresponding relevance criterion and an additional geographical relevance are determined for the goals of one or more target databases. Additional geographic relevance may, for example, be the relevance of the destination depending on the geographical altitude of the destination. The manner in which the geographical altitude of the respective destination is determined is initially arbitrary. An evaluation based on different, independent relevance criteria offers the advantage of a more accurate and reliable relevance determination in the current situation. In the example described above, the different and independent relevance determination allows, for example, the filtering of targets that have a high relevance based on their opening times, as well as of goals that by their exposed, especially elevated geographical, altitude even at a greater distance from the current position of the electric Device can be perceived identifiable by both the user and the optical pickup device.

In a further embodiment of the method according to the invention, it is provided that relevance criteria are at least partially dependent on one another and / or are at least partially weighted one below the other. Such a definition of relevance criteria is particularly suitable for the target databases, which comprise a particularly large number of data records or goals. In a further embodiment of the method, it is provided that, based on interdependent and / or weighted relevance criteria, an at least two-stage relevance determination can take place, in particular targets which have a high relevance with regard to the highest level of relevance determination being filtered out. The embodiment will be explained with reference to a contact database comprised by the electronic device. It can be provided that a First Relevance Criterion assigns a high relevance to all records contained in the contact database and / or contained in the particular geographic area. A second weighted relevance criterion may provide for higher relevance or weighting to those goals or contacts from which information has been used by the device in a certain predeterminable and past period of time to contact the destination, for example by telephone or in writing Relevance is assigned. According to a further embodiment of the method according to the invention, it is provided that relevance criteria can be influenced and / or created and / or stored by the operator. For example, the user can set up and store relevance criteria for a target database with special culinary destinations, which can be set to the category of individual goals, such as bar, restaurant, stand-up

Restaurant or Cafe, refer. In addition, it is possible, for example, to influence the relevance criteria in such a way that the relevance of the goals is assessed differently for different times of the day or weekdays (search for goals). In addition to the filtering of targets due to their relevance to the current situation, the graphical representation finally output by means of the method according to the invention can be improved, in particular, by an improved adaptation of the graphical symbols of the filtered targets before the current generation and output of the graphical representation. The way in which the respective adaptation criteria are to be used is fundamentally arbitrary. In general, however, an adaptation criterion will have a predefined setpoint value or a situation-dependent setpoint value, with which the graphic symbol is compared and adapted on the basis of the result of the comparison. Accordingly, it is particularly advantageous for the method according to the invention if the adaptation of the graphical symbols takes place as a function of the target database in which the corresponding target is stored. As a result, on the one hand the respective target can be assigned further information describing the corresponding destination by the corresponding graphical symbol and thus transmitted to the user. On the other hand, it is also possible to respond to the peculiarities of the objectives of a respective target database. By way of example, mention may be made of a so-called landmark target database which contains, in addition to the geographic position of the respective target, information on the three-dimensional structure of the respective target. From this information about the three-dimensional structure, it is possible, for example, to generate models with different levels of detail, which can then be linked or superimposed as a graphic symbol of the respective destination with the recording of the optical recording device and output to the user. The corresponding adaptation criterion may, for example, provide for the identification of the originating target database of the respective target.

Moreover, it is particularly advantageous if the adaptation of the graphical symbols takes place in dependence on the recording of the recording device. Which information about the reception of the recording device is used here is fundamentally arbitrary. In known digital image sensors as part of the recording device, however, it can be provided that information about the light conditions of the recording as well as about color ratios in the recording are used to adapt the graphic symbols. The particular advantage of this embodiment can also be described using the example of the aforementioned landmark database. By evaluating the information about the recording of the optical recording device, when using a model of a corresponding target, which is generated on the basis of the additional information about the three-dimensional structure of the target, it can be output to the image. units or image ratios of the recording of the recording device adapted and thus generates either a particularly optimal adapted to the recording of the recording device or a particularly prominent from the recording of the recording device graphical symbol of the target and output. Here, the corresponding adaptation criterion can be derived or defined, for example, from a situation-dependent statistical evaluation of the image data of the recording device.

A further advantageous embodiment of the method according to the invention, which likewise in no way exclusively affects the adaptation of graphical symbols of landmark destinations in the form of a model of the respective destination, is given by the adaptation of the graphical symbols as a function of the current position. In the example of the landmark models, this allows, for example, a generation and representation of a model of the target, which coincides in angular relationships, length ratios and other aspects with the actual view or a supposed view from the current position.

According to a further embodiment of the method according to the invention, it is provided that the adaptation of the graphical symbols takes place in dependence on the visibility of the target from the current position. In other words, this means that the graphical symbols of targets, which are hidden in the user's view or in the image of the environment by the images of the recording device of objects, terrain or the like, are displayed in an adapted manner. It can be provided that in the case of graphic symbols of hidden or invisible targets, the adaptation can consist in a graphical devaluation of the symbols, which can lead to the complete invisibility of the respective graphic symbol. This intuitively alerts the user that the corresponding target is not in the current position is visible. When assessing visibility, it is possible to derive or define adaptation criteria depending on terrain data or building data stored internally or externally to the device in corresponding terrain map databases or building map data databases. For meaningful interpretation of such data can also be provided that the current position and the orientation of the recording device are used to derive the adaptation criteria.

According to a further embodiment of the method, it can be provided that the adaptation of the graphic symbols takes place such that the graphic symbols at least partially comprise additional information about a destination. Which objectives contain additional information in the graphical symbol, and which information is encompassed by graphical symbols, is fundamentally arbitrary. By way of example, the name of the destination, special offers at the destination or through the destination should be mentioned here. The offers may be, for example, cultural offers, economic offers or the like. For example, the graphical symbol of a gas station may serve as the destination of a target database besides a

Pictogram describing the respective target database, in this case the refueling destination database, includes current fuel prices as additional information.

In a further refinement of the method, it is provided that the adaptation of the graphic symbols takes place in such a way that the vertical position of the graphic symbols is adapted with respect to the output on the output device. It is particularly advantageous if the adaptation of the vertical position of the graphical symbols is derived from at least the graphical altitude of the target. Furthermore, the current geographical altitude as well as the current position and orientation of the recording device can be taken into account. The thus adapted geographic symbols allow the Users an optimized identification and localization of the corresponding goals both on the output device output and in reality.

Various aspects of the teaching of the invention are shown schematically in the drawings and are explained below by way of example.

Fig. 1 shows the geometrical and geographical operations included in the first method steps. First, the current Position 1 of the mobile electrical device relative to a defined reference system, such as a geo-reference system detected. In the practical implementation, this is preferably done by a position determination unit, such as a GPS unit, through which the current position of the device in the form of position coordinates or geodesics can be determined. Based on the direction determination unit, the spatial orientation of the optical recording device is determined on the basis of the current position 1. For the horizontal portion of the spatial orientation of the receiving device, the radial boundaries 3 of the particular geographical area are determined on the basis of a predetermined or adjustable viewing angle. The radial boundaries 3 can be related to the recorded with the receiving part of the environment or be independent of this, in addition, starting from the current position 1, the radial

Extension of the geographical area determined by the stored in a memory destination search radius 4. From the area enclosed by the radial boundaries 3 and the arc of the target search radius 4 between the radial boundaries 3, starting from the current position 1, there results the geographical area 21 which is used to filter out targets.

The geographical area, like the current position, can be described by coordinates of the respective reference system and can thus serve as the basis for the filtering of destinations, insofar as these are likewise stored with corresponding or comparable coordinates in the respective target database. The geographically determined first filtering out of targets from at least one target database is followed by another filtering, which determines the relevance of individual targets in the geographical area on the basis of relevance criteria, wherein the relevance criteria are statically or dynamically adaptable and adapted to the user and the respective situation. It can be extremely advantageous if the horizontal relationship between the orientation of the receiving device and the horizontal orientation of a target 2 is determined. In Fig. 1, the determination is made with reference to the indicated north direction 5 with the aid of the angles a, ß and y. On the basis of the horizontal orientation of the target 2 relative to the orientation of the receiving device or to the north direction 5, a lifelike or angled horizontal arrangement of the graphical symbol of the target 2 can be achieved within the graphical representation, resulting in an intuitive orientation in the graph.

FIG. 2 shows a schematic representation of a mobile electrical device 6 as well as an output device 7 encompassed by the electrical device 6. A graphic representation 8 produced by the method according to the invention is output thereon. FIG. 2 likewise shows schematically the part of the environment 9 of the mobile electrical device 1 recorded by means of an optical recording device in the form of a terrain course. In addition to the part of the environment 9 of the device 1, the representation 8 comprises a graphic symbol 10 of a destination of a target database. The target in FIG. 2 originates from a landmark target database in which, in addition to the position of the target s, information about the three-dimensional structure of the target is stored, from which a model of the respective target is generated and / or adapted as a graphic symbol can.

In the example of FIG. 2, it follows that the graphic symbol 10 of the target represents a true-to-the-original model of the target adapted to the viewing direction and distance from the current position. In addition, it is possible to adapt the graphic symbol 10 with respect to the colors and / or the brightness to the recording of the graphic recording device. Further, in Fig. 2, the distance to the destination of the symbol 10 is included as additional information 1 1 in the graph 8. FIG. 3 shows a mobile electrical device 6 and the output device 7 included thereon, on which a graphic representation 8 is generated, which was generated by the method according to the invention. In the example of FIG. 3, the geographical area determined on the basis of the current position and the spatial orientation of the recording device does not coincide with the part of the environment recorded with the recording device or with the part of the environment output with the output device. As a result, a target located in the geographic area and filtered out by the filtering based on the relevance criteria can not be represented by an angular arrangement of the target's graphical symbol s from the current location and orientation of the host.

In this case, it is particularly advantageous if the graphical symbol 12 is adjusted prior to display on the basis of adaptation criteria derived from the current position, the orientation of the recording device and the part of the environment detected by the recording device. It is advantageous to adapt the graphic symbol 12 of the target in the form of a direction indicator, by means of which the user can determine in which direction the filtered target is located outside the represented part of the environment. In other words, this means that the graphical symbol 1 2 is adjusted depending on the orientation of the recording device and the current position of the mobile electrical device 1 1.

The graphical representation 8 of FIG. 3 comprises, in addition to the graphic symbol 12, a part of the environment 9 of the current position, which is recorded by the recording device and superimposed on the output device 7 with the graphic symbols of the filtered-out targets. 4 shows a mobile electrical device 6 with an output device 7, on which a graphic representation 8 according to an embodiment of the teaching according to the invention is shown. In addition to filtering out the destinations of different target databases on the basis of geographical position with respect to a certain geographic area and the filtering on the basis of relevance on the basis of at least one relevance criterion, FIG. 4 shows the advantageous effects of adapting the graphical symbols of the filtered-out destinations in such a way that the vertical position of the graphic symbols is adjusted with respect to the output on the output device.

By taking into account the geographical height values in the adaptation of the graphical symbols of the filtered targets, as shown in Fig. 4, a particularly intuitive and easily interpretable arrangement of the graphical symbols is achieved. As can be clearly seen, for example, from FIG. 4, the graphic symbol 13 a is located in the part of the environment 14 recorded with the graphic recording device much higher, namely on the mountain slope or on the ridge shown, whereas the targets of the graphic symbols 13 are clearly located in the valley. By appropriate adaptation of the graphical symbols can therefore for the

Users not only provide information on the horizontal orientation of the objectives, but also on the vertical height of the goals relative to the current position.

FIG. 5 illustrates the basic operations that are performed for adapting the graphical symbols of the targets considering the altitude and / or terrain data. In a hilly terrain 20, the receiving device of the mobile electrical device 16 is at a geographic height H l and is vertically aligned. A destination filtered out on the basis of relevance criteria from a culinary target database is assigned the corresponding graphical symbol 15. The geographical height of the corresponding target is H2. Based on the horizontal distance between the current position of the device 16 and the horizontal position of the target and the geographical difference ΔΗ, the angle between the orientation of the optical pickup and the vertical position of the corresponding target (a) can be determined by trigonometry corresponding adjustment of the graphic symbol 15 are made in order to allow a vertically true-to-scale representation of the graphic symbol 1 5. In the case of the target with the graphic symbol 1 7, a corresponding true-to-scale adaptation of the graphic symbol 1 7 would lead to a representation at the position 19. Since this position does not coincide with the actual position and accordingly can lead to a misinterpretation for the user, it is particularly advantageous if, in the adaptation of the graphic symbols, not only the geographical height values but also the corresponding terrain course 20 and thus the visibility of the target is taken into account by the current position. This can for example be taken from a Terrainkartendatenbank. It can then be ascertained by means of a corresponding analysis that the destination to which the graphic symbol 17 is assigned can not be seen from the current position of the mobile device 16 and the adaptation of the graphic symbol due to the geographical position

Height values are such that a display of the graphic symbol 7 at the position 19 is omitted.
