According to an embodiment of the present invention, the spatial information is provided as a set of real number triples. In particular, the spatial information may be provided in the form of CAD data of the closed area. According to another embodiment, a road network in the closed area may be represented by nodes and edges in the database means. The edges may, for example, be represented by linear splines or else higher-order splines. In particular, a respective edge may be assignable with associated costs or a cost function. The path determining means could then be arranged to take into account the cost of the edges in determining the path. In particular, the route determining means may be arranged to determine the route with the lowest total cost. The cost function can be proportional to the real length of the edge. In this way, the shortest route is determined by minimizing the cost function. However, according to another embodiment, the cost function may also be the "difficulty" of a particular path, for example due to from stairs or similar obstacles. In this way, for example, the best individual way for a particular group of people such. B. handicapped or blind persons can be determined by minimizing the cost function.

The following description refers to the attached drawings
taken in which like elements with the same reference numerals
The 1 shows the schematic representation of a Wegeiteitsystems 10 according to an embodiment of the present invention. The signage system 10 serves to locate and locate pedestrians in a closed area. The signage system 10 includes a central processing unit 20 and at least one terminal unit 30 that have a data connection 40 connected to each other. Typically, the central unit 20 trained as a central computer or server. In contrast, the terminal unit 30 as a fixed unit, as it is known for example from kiosk systems, or be designed as a mobile unit. The data connection 40 can be wired and / or wireless, such as WLAN, educated. Of course, the Wegeiteitsystem 10 be set up so that there are both fixed and mobile terminal units 30 may include. It can simultaneously wired and wireless communication connections 40 between central unit 20 and terminal unit 30 be furnished.
The central unit 20 includes a database resource 110 containing spatial information regarding the closed area. The spatial information allows a three-dimensional representation of at least a portion of the closed area in real time. For example, the spatial information may be a set of real number triples in the database means 110 to be provided. In particular, the spatial information may be provided in the form of CAD data of the closed area. Furthermore, in the database means 110 a road network may be represented in the closed area by nodes and edges in the database resource. The edges may, for example, be represented by linear splines or else higher-order splines. The central unit 20 further comprises a route determining means 120 adapted to determine a path within the closed area between a starting point and a destination point. Such methods for determining the route are generally known to the person skilled in the art and are therefore not explained further here. In addition, the Wegeiteitsystem has a visualization means 130 adapted to create a three-dimensional representation from the spatial information and the particular path in real time. Typically, this is achieved using virtual reality technology.
At the Wegeiteitsystem 10 according to 1 includes the terminal unit 30 a destination input means 140 adapted to define at least one target point located in the closed area. For this purpose, the terminal unit 30 a touch-sensitive screen and / or a pointing device and / or a keyboard and / or a voice input device, wherein the terminal unit may in particular have a graphical user interface. Typically, the graphical user interface includes a destination selection area for entering the destination. The way in this way by the destination input means 140 fixed destination point is then sent to the central unit 20 over the data connection 40 passed. There then determines the Wegbestimmungsmittel 120 the appropriate way, whereupon the visualization means 130 generates a corresponding three-dimensional representation of this path in real time. This real-time generated three-dimensional representation of the path is via the data link 40 to a means of representation 150 which is adapted, the three-dimensional representation on the terminal unit 30 play.
Typically, the starting point of the route is fixed at kiosk systems and corresponds to the location of the terminal. According to a further embodiment, the Wegeiteitsystem 10 but also a starting input means by which the starting point of the path can be determined. This is special Especially advantageous if the terminal unit is designed as a mobile device, or the routing system is called, for example on a non-building computer in a web browser to display a way. The starting input means and the destination input means may be realized in the same area. For example, first a starting point and then a destination point can be queried.
The 2 shows a guidance system 10 according to another embodiment of the present invention. Therein are the database means 110 and the path determining means 120 as well as in 1 in a central unit 20 arranged. Likewise, the destination input means 140 as well as the means of representation 150 in a terminal unit 30 , Unlike the in 1 shown system is in the embodiment of 2 however the visualization means 130 not in the central unit 20 but in the terminal unit 30 arranged. This embodiment requires some computing power of the terminal unit 30 as these are from the ones of the central unit 20 supplied raw data in real time the three-dimensional view must generate. However, in this embodiment, there is less bandwidth requirement of the data connection 40 provided, since not the complete graphs but only the raw data from the central unit 20 to the terminal unit 30 must be transferred.
The Wegeiteitsystem according to the two in the 1 and 2 shown embodiments allows the three-dimensional representation of a path from the user location to a user-defined destination in the closed area. Typically, this is achieved using virtual reality technology (VR technology). In this way, for example, the interior of a complex building can be displayed as it actually looks to the user. Thus, the way can be shown entirely from different perspectives and the user the way z. B. already go in advance virtually. The system is self-explanatory, the way query is answered in seconds, and an algorithm calculates and displays the cheapest way. This allows a user to see the entire building structure, its own location, the chosen destination, and the most favorable route to it. Due to the three-dimensional representation in real time (VR technology), the system is self-explanatory, so that no or at least hardly any reading and / or language skills are needed for operation. Furthermore, the completed area is displayed "as a whole". It is not, as usual, different floor cards behind or presented side by side. By omitting the map display objects can be displayed in three dimensions, so that these objects can be easily recognized later. The system conveys route and overview knowledge, which represents the highest form of spatial knowledge. Using the VR technique, the presented environment can be easily updated.
In the 3 various perspectives are shown, among which a user of the routing system can choose according to embodiments of the present invention. It shows 3A the so-called ego perspective, in which the path through the closed area is depicted as it would appear from the user's own perspective. In this respect, the user can get a good picture of his path. Another example of a perspective to select is that in FIG 3B represented so-called leadership perspective in which a "leader" or avatar leads the user along the appropriate path. The user gets a different view when he finds his way in the 3D shown vertical perspective. Likewise, an in 3C shown exocentric perspective in which the path is shown obliquely from above and thus contains some overview information. Finally, the user can also find the way in a so-called overall perspective, which in 3E shown, let represent. In the overall perspective, the entire building is displayed, so that the user is taught three-dimensional overview knowledge. By means of the overall perspective, the user can grasp the route to the desired destination at a glance and thus quickly receive the answer to his request. The guidance system therefore offers the user various perspectives, so that he can already walk the path virtually in advance (for example, in the egocentric or ego-centric perspective), before he then goes real. Additionally or alternatively, the user may see the building and the path in its entirety (for example, in the bird or exocentric perspective). The user can then safely access his destination, since he has already walked the path virtually once and the whole building is known to him after viewing. Using VR technology, any room in the building, or any section of the closed area, can be viewed from any perspective. In particular, the system is not limited to the above five perspective views, but other perspectives, such as perspectives adapted to specific applications, may also be presented.
In 4 is a graphical interface 300 according to an embodiment of the present invention. The graphical interface 300 includes a presentation area 310 in which the visualization means 130 generated three-dimensional representation of the way is displayed. By doing viewport 310 in 4 is exemplified the way in ego perspective shown. In doing so, the path becomes a line 315 marked. The lines 315 is according to 4 realized as a green, running at ground level three-dimensional tube. Of course, the lines 315 be realized in another form, for example as a three-dimensional bar, as a two-dimensional band or as an arrow or arrows.
The graphical interface 300 also has a destination dialing area 320 on. The one-touch dial area 320 is set up so that the user in the one-touch dialing area 320 select a destination in the closed area. It can be in the one-touch dial area 320 also predetermined fixed destination points can be selected. These predetermined destination points may be, for example, certain shops in a shopping center, certain clerks in an authority, certain gates in an airport, or certain zoos in a zoo. According to one embodiment of the present invention, the terminal unit 30 Furthermore, it is set up to output the distance from the currently displayed point on the way to the destination point, wherein the distance to the destination point and / or the duration until reaching the destination point are typically output optically and / or acoustically. This can be done by the terminal unit 30 for example, have a speaker. Furthermore, the terminal unit 30 have an input means. This input means may comprise a touch-sensitive screen and / or a pointing device (eg a computer mouse) and / or a keyboard and / or a voice input device.
According to one embodiment of the present invention, the graphical user interface 300 continue a perspective selection area 330 exhibit. In this area, by selecting a particular display style, the perspective in which the three-dimensional real-time representation is displayed can be changed. For example, by activating the corresponding icon in the perspective selection area 330 from the in 4 illustrated ego perspective on the in 5 shown exocentric perspective to be changed. Of course, any other representable perspective, in particular on the management perspective, the vertical perspective and / or the overall perspective, be changed.
In 5 is the avatar 340 shown, which goes the selected way to the destination point. Further shows 5 that also text information 350 such as floor information, room descriptions, etc. can be displayed in the three-dimensional real-time display. In particular, the starting point and / or the destination point can also be highlighted.
The 6 shows a graphical interface according to another embodiment of the present invention. It shows 6 the representation of a building in exocentric perspective, whereby in the individual rooms of the building, the brands of the respective shops and the visitor toilets as text or logo information 350 are displayed. In this way, a user can not only find the way to the store he is looking for but receives additional information about what other stores he passes on his way. In this way, a purchase can be planned more effectively. In contrast, shows 7 same way in ego perspective. In this case, the continuation of the path in the overlying floor is shown as extending below the floor ceiling lines. In this way, the user receives information about the course of the way in the upper floor, without "commit" this floor.
In 8th a comparison of the same way is shown in two different perspective views. Therein show the upper representations 8a the way out of the egocentric perspective, ie the way in which the user will then present himself in real life. In this way, a realistic impression of the way the user is created. On the other hand shows the 8b the way in exocentric perspective and gives the user in this way additional three-dimensional overview information. In particular, it may be worthwhile for a user to look at the same path from different perspectives or at least to look at certain complicated areas in the building from different perspectives. This can be done in the terminal unit 30 especially on the graphical user interface 300 , Also be arranged the possibility of forward and rewind the three-dimensional real-time display. For example, the forward, backward, and pause functions could be displayed using icons similar to the corresponding buttons on video or audio playback devices. In this way the functionality is conveyed intuitively and without corresponding language skills of the respective national language. Likewise, a function could be provided for faster forward and / or reverse of the three-dimensional representation. In this way, it is easier for the user to go to a certain place on the way.
In 9 is a guidance system 10 according to yet another embodiment of the present invention shown schematically. The signage system 10 is essentially the same as in 1 illustrated Wegeiteitsystem, but still has a control means 90 on. The control means 90 is with the central unit 20 connected so that the control means 90 the database resource 110 and / or the wayfinding means 120 can control. The interaction of control means 90 and central unit 20 will now be explained in more detail. In the database means 110 The spatial information is typically provided as a set of real number triples. In particular, the spatial information may be provided in the form of CAD data of the closed area. Furthermore, in the database means 110 a road network may be represented in the closed area by nodes and edges in the database resource. The edges may, for example, be represented by linear splines or else higher-order splines. Furthermore, a respective edge may be assignable with associated costs or a cost function. For example, the route determining means 120 set up to take into account the cost of the edges in determining the path. In particular, the route determining means 120 determine the path with the lowest total costs. The cost function can be proportional to the real length of the edge. In this way, the shortest route is determined by minimizing the cost function. However, according to another embodiment, the cost function may also reflect the "difficulty" of a particular path, for example due to stairs or similar obstacles. In this way, for example, the best way for a handicapped or a blind person could be determined by minimizing the cost function.
In this route determination by the Wegbestimmungsmittel 120 can now by means of the control means 90 are controlled intervention. For example, the control means 90 be set up to set costs for edges and / or edges and / or nodes to delete. In this way, via the control means 90 For example, current faults in building technology are taken into account. For example, the "cost" of a failed escalator can be significantly increased because the escalator is still usable but not so comfortable. Falls z. For example, if an elevator is completely off, its "cost" could be set to infinity, or the edge representing the elevator could be temporarily deleted. In this way, the defective elevator is left completely unconsidered during the route determination. Typically, the control means 90 integrated into a facility management system and monitored by the operator of the building. The control means 90 can still be used to update content. For example, the opening or closing of a shop can be fed via the control means in the routing system.
According to other developments, the control means 90 affect the 3D representation of the imaged space. Typically, the perspectives are not changed because they are user-specific. Furthermore, the control means 90 affect the selectable destination points, so that, for example (even only for a certain time) locked building areas are not selectable. Likewise, textual and / or pictorial information can be made available to the user via the control means. This can be done for example in a certain area of the user interface. The following are some examples of the use of the control means 90 specified. In one example, the elevators in a building have failed. The building operator can then exclude the elevators via the control means from the route calculation. The exclusion can be done, for example, by increasing the cost of the road network. The route determining means then calculates an alternative route that bypasses the locked elevators. In another example, an employee changes the department in an office building. The person responsible for the Wegeiteitsystem then simply changes the visible in the 3D display door plate of the office and updates the targets offered in the Zielwahlbereich goals and their position in 3D space, so that the employee can be found at his new workplace by a user. According to another example, the owner of a shop changes in a shopping center. The building operator changes the colors of the shop according to the new owner's corporate design and changes the store's logo visible in the 3D display. In addition, the operator of a shopping center within the space shown z. B. arrange billboards that refer to special offers of each store. As yet another example, in a particular area of the user interface, general information about the corresponding building / area / area is displayed, such as special (temporary) promotions, special offers, or events. All these changes or information can be immediately updated and made available to the user immediately.
In 10 is a guidance system with several terminal units 30 according to another embodiment of the present invention. This is based on the non-limiting assumption that the enclosed area is a large area and / or complex equipped with a complex road network. According to this embodiment, the routing system is set up to generate an identification code for a respective destination selection of a user and output it to the user. Thus, for example, the user who wants to reach the destination terminal from the terminal unit at the start location START to the terminal unit, receives after entering the destination assigned an identification code and issued. Subsequently, the user is shown the path from the location of the terminal unit at the location START to the terminal unit closest to the selected destination point AIM. This is done according to one of the embodiments described above. If the user follows this route and arrives at the nearest terminal unit, he can enter his identification codes at this nearest terminal unit. On the basis of the identification code, the nearest terminal unit can determine, for example, the destination point AIM and / or the route to it without further calculations. For example, this information can be stored centrally in the database means 110 or a dedicated memory means of the central unit and for each terminal unit 30 be stored accessible. The second terminal unit now displays again the path to the next terminal unit, etc. In this way, the user is in clear stretches of a terminal 30 led to the next, until he arrives at his destination point. Due to the clearly long sections of the user does not lose his orientation, since he only has to remember the way for the next section. Furthermore, the identification code allows fast and reliable input of the destination selection (eg by means of a contactless scanner).
