    [0001] The present invention relates to a method of geolocation and guidance in an environment where a pedestrian user is made to move, especially indoors. The invention also relates to a beacon and an application for the implementation of such a method. Geolocation and electronic guidance are widely used outdoors, particularly through GNSS ("global navigation satellite system") systems, mainly motor vehicles. While users spend more than 80% of their time inside 10 buildings, very few electronic means of geolocation and guidance are deployed indoors (or "indoor" in English). A known solution to this problem is to use a chip connected to a wireless network or to a terminal and implanted in a reader, in particular a smartphone, configured to recognize different points in the environment in order to locate the user. This type of solution needs to be permanently connected to the network or the terminal, which can lead to failures if the quality of the connection is low or non-existent. There is a need to enable a pedestrian to locate easily. in any type of environment, and to select a destination in this environment for guidance, by a means that is simple to implement, efficient, reliable, fast and inexpensive. The object of the invention is to meet this need and it achieves this, according to one of its aspects, thanks to a method of geolocation and guidance in an environment where a pedestrian user is made to move, especially indoors, the method using: at least one beacon, more preferably several beacons, detectable visually by the user and each arranged at a predetermined position of the environment and each having a unique identifier, a mobile reader, comprising a screen and / or a speaker, a geolocation and guidance application executable on said reader, configured to read the tag identifiers, and a mapping model of the environment, accessible by the application, in which the position of each tag is known, a method in which the reader present near a tag reads the identifier of the tag, the tags are arranged so that the reader can read only one e beacon at a time, the application displays on the screen of the player and / or di e by an audio message information depending on the last tag identified and linked to the cartographic model of the environment, and allows the user to find one's way Preferably, the application allows the user to select a destination; the application then determines the route between the position of the tag identified and the destination, and informs the user to guide it in the environment. Thanks to the invention, the user is intuitively, immediately and reliably guided in any type of pedestrian environment, for example a district of a city or a university campus, and at p. inside buildings. The invention can be used for guiding individuals in any type of building or space, for example a parking lot, including underground parking, a shopping center or a shopping arcade, a museum, a historic center, a center of 15 conferences, a salon or an exhibition, an office building, a hotel complex, an amusement park, a hospital, an administrative center, such as a town hall, a district court, a tax or security center airport, train or bus station, metro station or bus stop. The invention can be used for signaling evacuation routes, from interactive safety plans, in industrial environments and / or classified as hazardous, such as a nuclear power plant or a chemical plant, or to facilitate travel of persons with disabilities, with reduced mobility. The invention allows a high accuracy in the location of the user because each tag provides an exact location. A connection to a network, especially wireless, is not necessary to implement the method according to the invention at the time the location must be performed. This allows to respect the privacy of the user, which is not tracked permanently by a possible network. No transmission of information to third parties can thus take place, if desired. In addition, the invention can be implemented in an underground car park, including the lower floors, without risk of losing efficiency because of a weak or non-existent network connection.
    [0002] The geolocation and guidance method advantageously starts at the initiative of the user. The method according to the invention also allows autonomous operation, in that it avoids the need for a connection to an external communication network.
    [0003] The visual contact established with the beacon provides an intuitive help, the visual search being the first action of a lost user who seeks his way. The presence of the beacon can be visually indicated by any visual cue, for example a label. The beacon can be attached to a wall or door to-it other structural element of a building inviolably.
    [0004] According to the invention, it is not necessary for the user to be located permanently. This is not penalizing because only the localization at times and / or precise places is necessary during the guidance. On the contrary, a permanent location requires a more complex solution, greedy resources. The application can be made to launch automatically upon detection of a tag by the reader. Thus, the user does not have to launch the implanted application or to search for a connection to a wireless network. This is advantageous because a user seeking his way may be under stress, which can reduce his abilities. The method according to the invention can thus include the step of automatically launching the application in case of detection of a beacon, for example by any so-called NFC protocol (Near Field Communication). The detection can be done automatically by sufficiently approaching the reader of a tag. The solution according to the invention can provide a localization time, called TTF or "lime to fix" in glais, reduced to a few seconds, in particular less than 10 seconds, which makes it possible to give a response quickly to the user and to to relieve him in his search. Indeed, the response of the system does not depend on the possible waiting time to connect to the wireless network, including 3G ("third generation"). The method according to the invention also makes it possible to take into account all the ergonomic constraints of the place, thanks to the cartographic model, and the reader used. The number of tags can be related to the extent of the place and its complexity. The method is for example implemented by deploying within a zone between 1 and 100,000 tags, better than two tags. Locally, for example at the entrance of a building, only one tag can be deployed, the other tags concerning different buildings The identifier of a tag is for example a series of characters that provide information on the absolute position of the tag or its relative position in a benchmark related to the environment. It can also be a tag number and / or local map data. The cartographic model of the environment, that is to say the plane of the environment where the user evolves, is advantageously established from a functional model. To do this, a functional modeling software of the environment can be used. This software may rely on different sources, such as paper plans, digital files, photographs, satellite views and / or a site visit, to establish the model. The model advantageously contains the geometry of the different spaces of the environment, their function and use, for example hallway, office, meeting room, restaurant, toilet, staircase, elevator, coffee machine, etc. The template can also include the position and identifier of the tags. Walking and rolling networks, where appropriate, may also be included in the model. The template may be stored in a compressed format, and may be converted for use by the application to implement the method of the invention, for example when communicating with a tag. The set of cartographic models can be recorded in a database, for example contained in the computer where the functional modeling software was carried out which allowed the establishment of said models. The map templates can be stored on a computer on a computer server to which the mobile reader, or any other data transfer device, can connect to transfer the templates to the application. The map template can be saved entirely in the player's memory and be accessible by the application. In one variant, the application is configured for, when it is launched, in particular during the detection of a first beacon, to load the model by any means, for example by means of a wireless connection, 3G, 4G ("Fourth generation"), Bluetooth®, NFC, or by connecting to a data server. In a variant or in combination, the cartographic model is recorded in an active tag or downloaded via it, assimilated to a download terminal, available for example at the entrance or the reception of a building, and then downloaded by the application to pr of this tag. The download can be done after verification of the rights of the reader to access the requested cartographic model. In simple cases, it is possible to store the entire model each tag.
    [0005] In a variant, the cartographic model is distributed, that is to say that only a portion of the model is recorded on each tag, in particular a different portion for each tag, for example the portion relating to the immediate surroundings or close to the tag. position of the beacon in the environment. At each tag reading, the content necessary to guide itself in the environment close to said tag is advantageously downloaded by the application. A map data distribution software can be used to distribute and record, in a usable manner by the application, a portion of the model on the different tags according to their position in the environment. The registration format of the template may thus include penne concatenation features. t, from several portions of the model, to reconstitute it in its entirety. The cartographic model can know the geographical north, and possibly the location of auxiliary positioning means, such as WIFI terminals for example. Tags Another object of the invention is, according to another of its aspects, a beacon, more preferably a plurality of said beacons, each intended to be arranged at a predetermined position in an environment in order to be used for carrying out the method geolocation and guidance in said environment according to the invention, the method using a geolocation and guidance application executable on a mobile reader, each tag having a unique identifier related to its position in the environment, configured to be read by said reader to enable it to recognize the position of the beacon in the environment.
    [0006] The beacons are advantageously arranged in certain strategic locations of the environment, from the point of view of the pedestrian movement, for example the beginning of a corridor, an entrance hall, an elevator, a staircase. Beacons can be placed on walls or doors of buildings in the environment. They are each associated with a visual cue allowing the user to detect them visually. The beacons can communicate with the reader by radio waves, for example at 13.56 MHz or 2.4 GHz. Beacons may also not communicate by radio with the reader. The tags can in this case be optically passive, for example a QR code 10 observed by the reader, or optically active, for example with one or more LEDs emitting a coded signal, such as LIFI. The tags are preferably programmable tags, also called "tags" in English, for example using NFC (Near Field Communication) or Bluetooth technology, or incorporating a code. two-dimensional bar QR type ("quick response" in English) Each tag preferably includes a passive NFC chip. Each tag is thus a very simple element, easy to use, of low storage capacity, and having a very long life. Each tag may comprise a memory, especially of small size, for example between 10 bytes and 1T, better 10 bytes and 16 K, for example 8 K. In the case of a tag incorporating a QR code, which provides the advantage of being compatible with the majority of the current smartphones, the application can download in advance the cartographic model because the storage space of this type of support is most often limited. In addition, it is necessary for the user to launch the application itself, then observe the tag with the objective of the reader, the application being configured to recognize such a code from the acquired image. Tag programming and coding software can be used, in order to record information useful for implementing the method according to the invention and to ensure that they are recognized and read by the application. Each beacon is advantageously programmed with a unique identifier integrating its geodesic position information, that is to say its latitude and longitude.
    [0007] This identifier can be stored in the memory of the tag. In a variant, the identifier does not contain such information in itself. Depending on the environment and especially in the case where the memory capacity of the beacon is higher, in addition to the identifier, the beacon is programmed with all or 5 pe of the environmental mapping model, including a portion of the model generated by the functional modeling software and converted to the appropriate format. In addition, GNSS coordinates of the environment can be recorded in these tags in order to allow compatibility (continuity of the spatial repository and positioning) with the GNSS and cartographic systems. The content of the tags can be encrypted by any known means. The tag programming software can in particular be configured to protect them in writing. Thus, vis-à-vis the reader tags are passive, can only be read, avoiding being programmed fraudulently to deceive the user. Alternatively, the tags are active, other items may be recorded there, such as applications or messages, including commercial purposes, for example to report events, promotions, etc. This two-way link provides flexibility. Any interaction between the reader and a tag advantageously requires that the reader is present near said beacon. The distance between the reader and a tag 20 necessary for the detection of the latter may vary, in particular according to the technology used. This distance can be between 0 cm and 99 cm, better between 0 and 15 cm when using NFC technology. The reader can not; and identify only one tag at a time. . The interaction between the reader and a beacon terminates advantageously as soon as the proximity condition is no longer fulfilled. Beacons can be electrically powered or not. For example, transponders using NFC or Bluetooth (including BLE) technologies, themselves connected to a computer network and enabling bidirectional exchanges and volumes of tax data with the mobile reader, can be used. Player The reader is preferably a smartphone. In variants, the reader is a personal digital assistant or tablet.
    [0008] The reader advantageously comprises means enabling it to cooperate with the beacon, for example by NFC or Bluetooth® technologies, or QR code. It can thus comprise a camera and / or a reading antenna, in particular NFC. The reader is programmed to allow the implementation of the method according to the invention through the application. The screen of the reader is advantageously tactile. The reader may include a speaker for transmitting audio information. It can be determined using any sensor integrated in the reader, including gyroscope, accelerometer, atmospheric pressure sensor and / or compass, knowing the position and orientation of the beacon in the map model and the orientation of the reader during the detection of the beacon, if the user goes in the right direction that was reported to him after detection of this beacon, and in the case of a direction error, it can be reported to him. This can also help to estimate if it is on the right route. Another object of the invention is, according to another of its aspects, an application comprising code instructions executable on a reader and intended to be used for the implementation of the geolocation and guidance method in an environment according to the invention, the method using at least one beacon arranged at a predetermined position in the environment and having a unique identifier linked to this position, the application being configured during the execution of said instructions to read the identifier of the beacon and recognize its position in the environment, to allow the location and guidance of a user in the environment. The application is advantageously launched automatically during the detection of the tag, without additional intervention of the user. The application can be configured to be downloaded beforehand into an application market available at p. r reader, for example an Android, Apple or Windows application market. The application can still be supplied loaded on a computer-readable medium, for example a USB stick or SD card.
    [0009] In a variant, the application is configured to be automatically downloaded by the reader during the detection of the beacon, on such an application market. In another variant, the application is configured to be downloaded from a tag assimilated to a download terminal, available for example at the entrance or the reception of a building. The application is advantageously configured to read all the data contained in the tags, in particular their identifier and the cartographic model or a portion of the model of the environment, if appropriate. In the case where the content of the tags is encrypted, the application advantageously comprises means for decrypting at least a portion of said content. The application is advantageously configured for, when displaying a map on the screen of the player, indicate the position of the beacon on this plane. In a variant I 0 or in combination, the application can verbally transmit through the loudspeaker of the reader the position of the beacon to the user, as well as if necessary, as displacement instructions. The application can be configured to concatenate portions of the model, in the case of a distributed map model, to reconstruct it as beacons are read. In particular, in the case where the screen of the reader is tactile, the user can zoom, de-zoom and / or drag the cartographic model on the screen to explore different parts of the environment. In the case where the model is directly accessible by the application, the user conveniently consults and selects the destination where he wishes to go from a list offered to him according to its location. The destination selected by the user may be located near or within the position of a beacon recognized by the application. The user-selected destination may be a point of interest in the environment, such as an inquiry point, a toilet, a coffee machine, a cafeteria or a photocopier. One or more table (s) of correspondence between the model and a list of destinations can be loaded by the application, for example to update the cartographic model. Destination directories can also be generated and accessed by the application, the user being able to select his destination from these directories.
    [0010] The application T.ut be configured to automatically display on the map model points of interest based on the proximity of the tag and the destination selected by the user, for example to indicate the most important coffee machine. near or on the way to a point of sale.
    [0011] The application can be configured to implement an access control, in order to check whether the user has the right to penetrate into this or that part of the environment, in particular through parameters not accessible to the user. user who moves with the player. The application can transmit guidance messages to the user throughout the route of the tag to the destination. The guidance may consist of a display of a plane on the screen of the reader, this plane using in particular guide arrows. In a variant or in combination, the guidance may be audio. This does not pose a problem of autonomy of the reader, because the application does not use resource-intensive means, such as a GPS.
    [0012] The guidance is preferably performed at least partially by using one or more sensors integrated in the reader, such as a gyroscope integrated in the reader, accelerometer and / or an electronic compass. The application can be configured to detect the movement of the user through the sensor (s) and to indicate to the user whether he is heading in the wrong direction or later misjudging direction during guidance. The application can tell the user whether to use a staircase or an elevator. It is also possible to use available resources such as WIFI terminals for example, whose location is known by the cartographic model. When setting up a beacon, it is possible to record the power of the neighboring W77I terminals for this purpose, and to take this into account in the establishment of the cartographic model.
    [0013] Throughout the route, the position of the user can be updated by detecting other tags placed in the environment and placed near the reader. The latter can memorize the identifiers of the read tags in order to determine the consistency of the tags encountered and the path followed. Complementarity with other locating means may be provided, including WIFI terminals as detailed above. Additional information, previously contained in the reader and accessible by the application, can be loaded when the content of the tag is read by the application, for example information on the profile of the user, indicating no ent s' he is handicapped, visitor of the environment or professional, and / or information perme. t for example to indicate the emergency exits of the environment in the event of emergency evacuation, or the place of the car in the case of a car park. In the case of a disabled user, the map template can indicate where wheelchair access is located, for example. Another object of the invention is, according to another of its aspects, a method of installing beacons according to the invention, in an environment where a pedestrian user is made to move, no internally, the installation method using a cartographic model of the environment, in which, when installing tags in the environment, the position of each tag in the environment is indicated in the cartographic model and is linked to a unique identifier of the tag, to allow the location and guidance of the user in the environment, by implementing the method according to the invention. The position of the tags in the model c. The graphic can then be signaled by the reader to the user by any means, for example by a cross, a large point, for example a bright color, or a large circle of bright color. The method of installing the tags may include their programming with an identifier. At least a portion of the map template can be uploaded to the tag as part of its initial programming. The invention will be better understood on reading the following description, which will be followed by non-limiting examples of implementation thereof, and on examining the appended drawing, in which: FIGS. 1 and 2 schematically illustrate various steps and elements for implementing the geolocation and guidance method according to the invention; FIGS. 3A to 3C are examples of cartographic models of the environment used for the implementation. FIG. 4 represents a beacon variant according to the invention, and FIGS. 6A to 6D represent screenshots of the reader illustrating an example. FIG. operation of the application according to the invention. FIG. 1 shows different steps and elements enabling the implementation of the geolocation and guidance method according to the invention, in an environment where a pedestrian user is made to move, indoors in the example in question, for example a building or a public space. The method according to the invention implements beacons 1 arranged at predetermined positions in the environment and each having a unique identifier id linked to its position in the environment. The pedestrian user has a mobile reader configured to detect beacons 1 when placed nearby. This player executes an application 3 of geolocation and guidance, accessing the cartographic model 4 of the environment. In the example described, the reader 2 is a smartphone and comprises a touch screen, a memory and a speaker. The invention is however not limited to a particular type of mobile reader 2. The application 3 is advantageously launched by the reader 2, automatically, during the detection of a first tag 1, and it is configured to read information contained in the tag 1. In the example described, the application 3 is downloaded beforehand in a step 45 in an application market 21 accessible from the reader 2, for example market of Android, Apple or Windows applications. In variants, the application 3 is configured to be downloaded automatically by the reader 2 during the detection of the tag 1, on such an application market 21, or to be downloaded directly from a tag 1, in particular 25 a beacon acting as download terminal. The cartographic model 4 of the environment is advantageously established, during a step 41, at p of a functional model, by using a functional modeling software, based on different sources 40, namely plans on paper, digital files and photographs in the example considered. In a step 42 shown in FIG. 1, the cartographic model 4 is entirely saved in the memory of the reader 2 and is accessible by the application 3.
    [0014] In a variant, the application 3 is configured to, at its launch, load the model 4 by any means. In a variant or in combination, during a step 44, the cartographic model 4 is recorded in an active tag 1, available for example at the entrance or the reception of a building, and is then downloaded by the user. application 3 from this bali itself. Examples of cartographic models 4 are shown in FIGS. 3A to 3C. These models advantageously contain the geometry of the various spaces of the environment, their function and use, for example the amphitheatres and the reception desk of a p. e of the university campus considered in Figure 3A, the various offices, toilets and corridors of the office floor considered in Figures 3B and 3C. The cartographic model 4 advantageously also includes the position and the identifier of the beacons 1. A beacon 1 according to the invention is shown in FIG. 4. In the example considered, the beacon 1 is a programmable beacon using the NFC technology, comprising a memory, of size for example between 10 bytes and 8K. It may be a NTAG 203 or NTAG 213 chip. In the variant shown in FIG. 5, the tag 1 incorporates a two-dimensional QR-type bar code 11. The unique id identifier linked to the position of the tag 1 in the environment is read by the application 3 in order to recognize the tag 1. This identifier id is stored in the memory of the tag 1 during a step 43 shown in Figure 1. To do this, programming software and coding tags 1 can be used. The identifier id of the tag 1 can integrate a geodesic information. The identifier id is preferably encryptedly stored in the memory of the tag 1, the application 3 executes a proper algort e to decrypt. Figure 2 shows in more detail this. Prior to the implementation of the method according to Figure 2, after its establishment in step 41 described above, the cartographic model 4 is recorded at a step 46 in a compressed format, and is advantageously converted to be recognized and used by the application 3. In parallel, the set of cartographic models is recorded in a step 51 in a database 50, for example contained in the computer 30 where was executed the functional modeling software. The cartographic model 4 is recorded, in the example described, in the tags 1 during their programming in step 49.
    [0015] In a variant, during a step 48, the cartographic model 4 is distributed, a portion only being recorded on each tag 1, for example a different portion for each tag, preferably the portion relating to the immediate surroundings or close to the position of the tag in the environment. In this case, a map data distribution software is advantageously used to distribute and record, in a manner usable by the application 3, a portion of the model on the different beacons 1 as a function of their position in the environment. The progress of the method according to the invention through the application 3 will be described with reference to Figures 6A to 6D. When the reader 2 is placed near a beacon 1, the latter detects it and starts the application 3 automatically. The application 3 displays on the screen 5 of the reader 2 the cartographic model 4 of the environment, as represented in FIGS. 6A to 6D. The application 3 reads the id identifier of the tag 1 and recognizes its position in the environment. The position is transmitted to the user, and is displayed on the screen 5 of the reader 2, for example by a large dot, as shown in FIG. 6B. In a variant or in combination, the position of the beacon 1 is transmitted via the loudspeaker of the reader 2. As can be seen in FIG. 6B, the screen 5 of the reader 2 is touch-sensitive, the user can zoom in on the screen to explore different p. es of the environment and appreciate the details. The user advantageously selects the destination of the cartographic model 4, located near or not to the position of the beacon 1 recognized by the application 3, for example from a list that can be offered to him depending on his location in the environment and / or in destination directories accessible by the application 3. The application 3 calculates and / or shows the route between the position of the tag 1 and the destination selected by the user, and informs him in order to guide the environment, e - for example the route on the screen 5 of the reader 2 by lines and arrows, as shown in Figures 6A to 6D. In a variant or in combination, the guidance may be audio. The guidance is preferably performed using at least partially a sensor integrated in the reader 2, for example accelerometer, gyroscope and / or integrated compass. The application 3 is advantageously configured to indicate to the user if he is going in the wrong direction or is mistaken later direction during guidance, thanks to the movements detected by the reader. Throughout the route, the position of the user is advantageously updated by the detection of other tags 1 disposed in the environment and coming close to the reader 2. Of course, the invention is not limited examples of embodiments have just been described, the characteristics of which can be combined within non-illustrated variants.
