Description

INFORMATION DISPLAY MANAGEMENT SYSTEM THROUGH MOBILE SUBSTRATES

  FIELD OF THE DISCLOSURE OF THE PROFILES OF TARGET PEOPLE PRESENT IN THEIR VICINUM The invention relates to the field of the display of information, possibly of an advertising nature, intended for a public, or information of interest to a given population, by means of display support (s) at least partially mobile.  By display medium (or mobile support) is meant here a material comprising a mobile display part, or mobile, because it is mounted on a vehicle, possibly for public transport, and intended to support a poster, possibly of an advertising nature, or to display information (or information), possibly of an advertising nature, for a given period of time so that it (s) can (s) be observed by a public situated in its vicinity.  Mobile advertising is traditionally carried by at least partially mobile media such as billboards (possibly scrolling) or display screens for example light-emitting diodes (LED) or plasma) rotatably mounted on a base or mounted on vehicles using, preferably, very busy routes (city boulevards, major highways, airport or train stations, for example).  These advertisements may have been affixed by gluing on the mobile medium.  There are also mobile media with several posters scrolling in turn, or selectable in a tank and displayed on the face of the mobile support for a predetermined time.  The invention relates to mobile supports for selecting one of several displays or displaying on a screen information, information, an image or a video clip.  The display companies (so-called billboards) have at their disposal 2906626 2 fixed and / or mobile display networks and offer their advertising customers qualified displays according to the desired target.  The qualification of the display networks is a standard parameter for advertisers and billboards through a particular nomenclature 5 generally dividing the population into five levels of social level (A, B, C, D, E): thus, if the advertiser is interested in targeting a cadre population, it will require Category B targeting; to a senior management population will correspond Category A targeting, etc.  For example, a Category A signage network is often located in a large city, near business offices or residential neighborhoods.  However, the qualification of the display networks remains limited to the predefined categories and there is no other technical means of targeting the audience.  At most, some advertisers may have surveys carried out on the spot, that is to say close to the areas in which the mobile advertising media are moved, to know the profile of passing individuals and the impact that left this advertisement in their minds.  This single way of measuring targeting is very little used because it is expensive and provides the opinion of only a very limited panel of people (very) unrepresentative of the entire population.  In addition, it does not react quickly, given the time required to obtain and analyze the results of opinion polls.  The object of the present invention is therefore to solve the problem set out above in order to provide a more precise targeting that is as much as possible in affinity with the passing public.  To this end, the invention proposes a system for managing the display of information on at least one mobile display medium at least partially along a path, further comprising: locating means for determining persons targets, associated with profiles defined by objective and / or subjective characteristics, likely to be present in a given time interval in at least one first zone (of known perimeter, attached to a part of the display medium that follows the trajectory, located in the vicinity of the latter, and in which it is in visibility of the target 3 2906626), given the trajectory followed, the first storage means responsible for storing the profiles of the target persons, calculating means responsible for dividing in groups, each of which is defined by at least one profile feature, the specific target persons who are likely to 'being present in the first zone in the time interval, correspondence means responsible for establishing matches between the groups and information to be displayed, and control means responsible for causing the display to be displayed by the support of displaying at least one piece of information corresponding to the characteristic (s) of one of the groups chosen according to the number of target persons it groups compared with those of the other groups.  The invention thus has a dual function, the first is that of analyzing the average profile of the public attending an area located near a mobile display medium (for example, if the public has been previously qualified AB, the the invention makes it possible to verify it, or even to refine the qualification), and the second is that of the targeting of the public according to the result of the analysis obtained, in order to provide the public with information corresponding to at least a part of his average profile.  In this way, the invention makes it possible to achieve the objective desired by any advertiser, namely the targeting of the public by micro-segmentation and the display of really useful information, thus ensuring the optimization of the advertisers' budget.  The system according to the invention may comprise other characteristics that can be taken separately or in combination, and in particular: the display support may for example comprise a part dedicated to the information display and rotatably mounted on a base so as to follow a circular path according to a chosen rotational speed;

FIG. 7 illustrates an example of a table including information relating to the minimum / maximum quotas of information to be displayed over a given period of time; FIG. 8 schematically and functionally illustrates an example of a second embodiment of an information display management system according to the invention, and - Figure 9 illustrates, schematically and functionally, an embodiment of a management device according to the invention can be used in the display management system shown in Figure 8.  In the following, the elements (or modules) fulfilling identical or similar functions will bear identical references.  Referring first to FIG. 1, there is shown an information display management system according to a first embodiment of the invention.  As illustrated in FIG. 1, a management system according to the invention comprises at least one display medium SA, which is at least partially mobile, means for locating target persons ML1-s ML3, a first memory MS1 , an MCR correspondence module, an MCL calculation module and an MCM control module.  In what follows we consider only the case of a management system comprising a single display medium SA, to simplify the description of the invention.  However, the invention applies to any management system comprising at least a mobile display medium SA.  Furthermore, in what follows, by way of illustrative and non-limiting example, the information to be displayed is of an advertising nature.  But, the invention is not limited to this type of information.  It also concerns the display of information relevant to a given population.  The display medium SA can be either mounted on a vehicle VT (as illustrated in FIG. 1), and in this case its mobility is governed by that of the vehicle VT, or fixed by means of a base (or a pedestal) BF in a chosen place, for example on a square, and only its display AF can be rotated relative to its base BF (as illustrated in Figure 2), and in this case its mobility is governed by that of its AF display.  In the following, by way of illustrative and nonlimiting example, the display medium SA is mounted on the body of a vehicle VT, for example public transport.  The display medium SA is for example an advertising panel 25 comprising a block (or mechanism) loading MA in which is stored (for example by stacking) a set of advertising posters Ai.  For example, the loading block MA comprises three posters A1 to A3 (i = 1 to 3) that it is responsible for displaying (or presenting) on a visible window of the public through a mechanism, individually, or by 30 pair (see even by triplet), according to a command adapted for this purpose.  It should be noted that the invention is not limited to this type of display medium SA.  It relates in fact to any type of display medium that can be mounted on a VT vehicle or having a rotating display AF, 2906626 16 capable of displaying on command information or information, including scrolling displays or screens. light-emitting diode (LED) or plasma display, for example.  The (digital) display screens make it possible to avoid all the storage and display mechanics.  In addition, they may optionally transmit the data defining the information to be displayed with the display command.  The display medium SA is associated with a first zone Z1.  The latter is located in its vicinity (for example it surrounds it at least partially) and people and / or individual vehicles or public transport VT can move while viewing the information displayed by the support of SA display.  The perimeter of this first zone Z1 is known.  Furthermore, this first zone Z1 is attached to a part of the display medium which follows the path TR (that is to say to all the display medium SA in the case of FIG. 1 and to the AF rotary display in the case of Figure 2).  A schematic example of trajectory TR of a vehicle VT on a roadway (or road) RC is illustrated in FIG.  The arrows FO materialize the velocity vector at the instant considered of the vehicle VT (and thus 20 of the first zone Z1 attached to its display medium SA).  The locating means ML1 and ML2 (or ML3 and ML4) are responsible for determining target persons who are likely to be present in a given time interval in at least the first area taking into account the track TR followed.  By target person is meant here a person to whom a profile defined by one or more objective and / or subjective characteristics has been associated.  Among the objective characteristics that can be used, mention may in particular be made of the number of past passes in front of the display medium SA concerned, the number of visualizations of each of the advertising posters, and the like.  Among the subjective characteristics that can be used, mention may be made of gender, age, socio-professional category, occupation, professional and / or personal and similar areas of interest.  In general, any type of criterion (or characteristic) can be used to define a profile.  It should be noted that the profiles can be advantageously defined from the profiles used by the communication network operators to target their customers.  s The first memory MS1 is responsible for storing the profiles of the target persons.  Here, by time interval, is meant a time separating two successive positions of a display medium SA (or its rotary display AF) P (ti) and P (ti + 1), as illustrated in FIG. 4.  At time ti, where lo corresponds to the position P (ti) of the vehicle VT (and therefore of the first zone Z1), the locating means ML1 and ML2 (or ML3 and ML4) determine the positions of the target persons.  The instant ti + 1 is used by the locating means ML1 and ML2 (or ML3 and ML4) to predict the location P (ti + 1) where the vehicle VT (and therefore the first zone Z1) will be located, taking into account its position P (ti) and its vector velocity at time ti.  It is therefore at the predicted position P (ti + 1) of the first zone Z1 that one must determine if target persons are present at time ti.  It is considered here that the speed of movement of the display medium SA (or its rotary display AF) is significantly faster than that of a pedestrian.  The calculation module MCL is responsible for distributing in selected groups the target persons that have been determined by the locating means ML1 and ML2 (or ML3 and ML4) and which are therefore likely to be present in the first zone in the region. 'time interval.  By group is meant here a set defined by at least one profile characteristic.  Note that different groups are defined by combinations of different characteristics.  Moreover, it will be noted that a group can be defined by all the characteristics of a profile, or even of several profiles.  As illustrated, the management system may optionally comprise a definition module MD responsible for defining the aforementioned groups from the profiles stored in the first memory MS1, and to provide the definitions of these groups to the calculation module MCL.  The correspondence module MCR is responsible for establishing links between the groups (linked to the profiles that are stored in the first memory MS1) and the information that must be displayed by the display medium SA.  In other words, in the example described, the correspondence module MCR stores a correspondence table between the 5 groups and the corresponding advertising posters respectively.  The control module MCM is responsible for causing the display device SA to display at least one piece of information that corresponds to the characteristic (s) of a group that is chosen at least according to the number of target groups that it groups compared to those grouped by the other groups.  For example, and not limitation, the MCM control module may cause the display medium to display at least one item of information corresponding to the characteristic (s) of the group that groups the largest number of target persons. .  In other words, when the MCM control module receives from the calculation module MCL the distribution on the different groups (linked by the correspondence table to the various posters Ai available) of the target persons who are considered as present in the first zone. Z1, it selects the group that is associated with the largest percentage and generates a display command for the relevant SA display medium to display the display Ai corresponding to that selected group. in the correspondence table (MS1).  It is recalled that in the presence of digital display screens, it is conceivable that the display control comprises the data defining the information to be displayed or, more simply, a descriptor (or identifier) of the information to be displayed. (to avoid network overload during transmission).  This descriptor is converted by the processor MR, which comprises the display medium SA (and which is responsible for translating the received display command into instruction (s) understandable (s) by the display mechanism MA), in information data to be displayed, for example by means of a correspondence table between different descriptors and information (advertising) to be displayed.  In the nonlimiting example illustrated in FIG. 1, the MCM control module, the first memory MS1 and the correspondence module MCR, as well as the eventual group definition module MD are located in an SS service server. .  Moreover, in the nonlimiting example illustrated in FIG. 1, the calculation module MCL and part of the locating means ML2 are located in a calculation server SC.  A complementary part of the locating means ML1 is distributed in mobile communication equipment Tj that

  carry at least some of the target persons and in the VT vehicle carrying the SA display medium. Note that in the case of a rotary display AF rotation law can be known in advance, so that we can know at any time its orientation with respect to a reference direction. It is then useless to equip the display medium SA with locating means ML1. This may nevertheless be useful when the detection is done locally (as will be seen later with reference to FIGS. 8 and 9).

More specifically, in the nonlimiting example illustrated in FIG. 1, the vehicle VT and at least some of the target persons are equipped with a mobile communication terminal Tj (here j = 1 to 4) in which an implant is located. ML1 satellite positioning module. For example, the mobile communication terminals Tj are mobile phones that are connected to a mobile (or cellular) communication network RM. The latter is for example a GSM / GPRS network (Global System for Mobile Communications / General Packet Radio Service) whose cells are managed by base stations (called BTS (for Base Transceiver Station in English)). Of course, the cellular communication network may be of any other type as long as it allows the establishment of over-the-air (radio and / or terrestrial and / or satellite radio) communications. Therefore, it may be a UMTS network (Universal Mobile Telecommunications Service in English) whose base stations are called Nodes B, or a wireless LAN 30 type WiFi or WiMAX, for example. It will be noted that the calculation server SC preferably belongs to the operator of the mobile network RM. It is recalled that a satellite positioning module ML1 is responsible for delivering position measurement estimates of the equipment in which it is implanted, based on signals transmitted by a constellation of positioning satellites of a network. positioning of the RNSS type (for Radio Navigation Satellite Service in English), or GNSS, such as for example the GPS network, or the GLONASS network, or the future GALILEO network. It will be noted that the accuracy of the position measurements can be enhanced when the constellation of positioning satellites is coupled to a so-called augmentation system, of the SBAS (Satellite Based Augmentation System) type, such as for example the EGNOS system. Each satellite positioning module ML1 transmits the positioning data that it determines to a server of the network which is responsible for storing them in a customer information database of the operator of the mobile communication network RM. This database may be the Home Location Register (HLR) if the subscriber is connected to the radio access network of his home network or the VLR (Visitor Location Register) if the subscriber is connected. to the radio access network of another operator than his own. In the nonlimiting example illustrated in FIG. 1, the calculation server SC furthermore comprises a memory MS2 in which the definition of the perimeter of the first zone Z1 is stored. This definition comes from the SS service server, which also stores it, for example in the first memory MS1 (or in any other memory). As indicated above, this first zone Z1 is determined so as to cover part of the space surrounding a display medium SA and in which target persons can circulate, possibly inside a VT vehicle, while by being able to observe the poster Ai which is displayed. The definition of this first zone Z1 can be modified in time by the manager of the service server SS, in order to cover a more or less extensive territory, or to cover a larger or smaller population, especially in view of the time of the day (the population density around the sign is generally lower during the night, for example).

FIG. 5 shows schematically, in a view from above, an example of a first zone Z1. Here, the first zone Z1 is composed of: a first portion Z11 corresponding to a parcel of territory facing the display medium SA, substantially rectangular, with a large side R and a small side 02-03 equal to the width the display support SA (defined between the points 02 and 03; 01 designating the center), and - two lateral parts Z12 and Z13 formed of sectors of 45, radius R and respective centers 02 and 03. lo Of course other values for the angular sectors may be envisaged as long as they allow the target persons to view the poster Ai that is displayed. Moreover, other decompositions of the first zone Z1 can be envisaged. In the nonlimiting example illustrated in FIG. 1, the ML1 positioning modules, installed in the mobile terminals Tj of the target persons and of the vehicle VT, transmit their geographical positions to their mobile network RM. The ML2 part of the location means, here implanted in the calculation server SC, is then arranged to access the HLR information database in order to determine the geographical position P (ti) and at least the prior geographical position P (ti-1), and deduce from these successive geographical positions the speed of the vehicle VT. It can also be envisaged that the vehicle VT transmits its speed directly at the same time as its position. Then, the ML2 part predicts the following position P (ti + 1) of the vehicle VH, and therefore of the first zone Z1 from the geographical position P (ti) and the associated speed. The ML2 part then accesses the HLR information database again to determine all the clients whose geographical positions are substantially contained in those defining the first zone Z1 for the predicted position P (ti + 1). For this purpose, the ML2 part 30 compares the stored geographical positions (preferably only the target persons designated as such by the SS service server) to those which define the first zone Z1 given the definition of its perimeter which is stored in the second memory MS2, and each time it detects an identity corresponding to a target person, it records the identifier of the corresponding target person. In a variant, it may be envisaged that the identifiers of the target persons and the corresponding geographical positions are periodically stored in a memory MS3 of the calculation server SC. In this case, the ML2 part has only to make its comparison from the geographical positions stored in the memory MS3. Whenever the ML2 part has determined all the target persons present in a first zone Z1, preferably within a given time interval, it communicates their identifiers to the calculation module MCL. The latter can then divide into the groups, the definitions of which have been communicated to him by the service server SS and which are for example stored in the second memory MS2 with the definitions of the profiles, the target persons who are likely to be in the group. first zone is Z1 in its predicted position P (ti + 1). Then, it transmits to the control module MCM a message comprising the distribution of the target persons on the different groups. A nonlimiting example of determination of a distribution will be described below.

Over an elapsed time interval IT, the ML2 part of the location module has determined that 50 persons are likely to be present in the first zone Z1 in its predicted position P (ti + 1), for example located in a neighborhood of 'business. For example, it may be agreed between the manager of the SS service server and his advertiser clients to make a selection according to selected criteria, such as, first of all, gender and then the socio-professional category. Groups have therefore been formed from these criteria, and then transmitted to the calculation server SC (RM mobile network operator holder of personal information on these customers). An example of division into groups and subgroups is given in the following table. Total number of Sex Categories 2906626 23 socio-professional target persons 50 women: 32, ie 64% 17 A 15 B men: 18, ie 36% 12 A 6B It should be noted, as illustrated, that the calculation server SC can for example understand an MT timing module responsible for making the MCL calculation module work according to a chosen period, rather than in a quasi-continuous manner. When the MCM control module receives the distribution message, it chooses one of the groups object of the distribution, then determines in the correspondence module MCR the poster Ai which corresponds to this selected group (of course taking into account the posters Ai available in the considered display medium SA) and generates a display command to this display medium SA so that it can display the determined display Ai. In the case of the example described above, the control module MCM retains that the population most represented in the first zone Z1 is the female population of socio-professional category A. By accessing the correspondence table MS1, the control module determines that the socio-professional category A corresponds, for example, to an advertising poster Ai of an advertiser relating to jewelery or high-end cosmetics.

It should be noted that the decision for the selection of the poster Ai can be acquired with one or more levels of criteria. In the previous case, we went down to two levels of precision {sex + socio-professional category}, but this example is not limiting. In the example described with reference to FIG. 1, the display control is transmitted to the display medium SA via the mobile network RM. The display medium SA therefore comprises a processing module MR equipped not only with a display control message processing processor 2906626, but also means for receiving radio (or radio) signals. It should be noted that the MCM control module preferably selects a group only if it concerns at least two target persons. It should also be noted that the presence detection may also relate to occupants of VH vehicles, in particular those providing public transport. Indeed, it is possible to have predictive information on people who regularly use means of public transport VH, such as buses, subways, trains or buses, whose routes are generally predetermined and subject at fixed times. For example, if people use a public transport vehicle every day at the same time on the same line. Therefore, for these target persons it is not necessary that they have a location means, such as a satellite positioning module ML1. It is indeed possible to predict their presence inside a public transport vehicle VH which must pass through a first zone Z1 thanks to the predictive information of the public transport network (relating to the habits of the target persons and to the routes of the vehicles VH). By equipping VH public transport vehicles with a locating means, such as for example a satellite positioning module ML1, the part ML2 of the locating means can also detect the presence of a public transport vehicle in the first Z1 area when comparing geographical positions. This part ML2 must, however, include a prediction sub-module responsible for determining the target persons who are not equipped with a mobile terminal Tj but who are likely to be present in the first zone Z1 in its predicted position P (ti + 1) because they are presumed to be embarked on a VH public transport vehicle which is likely to be present in the first zone Z1 in its predicted position P (ti + 1), based on predictive information provided by the operators of the transport networks and for example stored in the memory MS2 or MS3.

In this case, the calculation module MCL is responsible for distributing in the groups defined by the manager of the service server SS the target persons detected individually (via their positioning modules ML1) as well as the target persons determined by the sub-group. prediction module 5 of the ML2 part. Moreover, it can also be envisaged that at least some of the target persons have a mobile terminal Tj equipped with a measurement module responsible for measuring physical quantities relating to the movements of the target person it equips. For example, the measurement module is responsible for measuring the speed and / or the changes of direction of the mobile terminal Tj that it equips, and for sending to the calculation module MCL (here implanted in the calculation server SC) the measured values, via the RM mobile network. In this case, the calculation module MCL is responsible for determining the target persons that are likely to be present in the first zone Z1 in its predicted position P (ti + 1), taking into account the physical quantities transmitted by their mobile terminals. Tj. For example, the calculation module MCL determines from the physical quantities received which are the target persons who are likely to be present in the first zone Z1 in its predicted position P (ti + 1) and who are about to leave it, but also which target persons are outside the first zone Z1 in its predicted position P (ti + 1) and are about to enter it. He is then able to not retain for the distribution the target persons who are likely to quickly leave the first zone Z1 in its predicted position P (ti + 1), but to retain those who are likely to enter it quickly. . For this purpose, the calculation module MCL can for example begin by pre-retaining the target persons who are located at a distance from the predicted position of the edge (or frontier) of the first zone Z1 (in its predicted position P (ti +1)) which is less than a first chosen threshold S1. Other target persons are automatically selected. Then, it multiplies the speed SP of a pre-selected target person, which has been considered by the ML2 part of the locating means as likely to be present in the first zone Z1, by a time of attention which can take two values: a first value V1 when this target person is likely to leave the first zone Z1 in its predicted position P (ti + 1) (taking into account the direction 5 of its velocity vector), and a second value V2 when the target person is likely to enter the first zone Z1 in its predicted position P (ti + 1) (taking into account the direction of its velocity vector). Finally, it compares with a second threshold S2 chosen the result of each multiplication (SPxV1 or SPxV2) concerning a pre-selected target person, in order to retain only those that are associated with a result greater than the secondseuil S2. The first V1 and second V2 attention time values are chosen according to the level of attention a target person has towards a displayed information when leaving the first zone Z1 (in its predicted position P (ti + 1)) or when it enters. This level being generally higher when entering the first zone Z1, V2 is preferably chosen to be greater than V1. In a variant which corresponds to the situation illustrated in FIG. 6, a second zone Z2 can be connected to the display support SA. More precisely, a second zone Z2 is defined around at least a portion of its first zone Z1, in order to take into consideration in the aforementioned treatment only those target persons who are considered likely to be present in the first zone. Z1 or in the second zone Z2. For example, the first MS1 and / or the second memory MS2 can also store the definition of the perimeter of the second zone Z2. In this case, the ML2 portion of the locating means can determine the target persons that are likely to be present in the second zone Z2 as it does for the first zone Z1 in its predicted position P (ti + 1). The ML2 part of the locating means, here implanted in the calculation server SC, predicts the position P '(ti + 1) occupied by the whole of the second zone Z2 taking into account the definition of its perimeter (which is stored in the second memory MS2) and its predicted position P (ti + 1) of the first zone Z1. Then, ML2 accesses the HLR information database to determine all clients whose geographical positions are substantially contained in those defining the second zone Z2 for the predicted position P '(ti + 1). To do this, the ML2 part compares the stored geographical positions (preferably only target persons designated as such by the SS service server) to those 5 which define the second zone Z2 given the definition of its perimeter, and each time it detects an identity corresponding to a target person, it records the identifier of the corresponding target person. The calculation module MCL can then determine from among the persons targets which are likely to be present in the second zone Z2 in its predicted position P '(ti + 1) those which are likely to quickly enter the first zone Z1 in its predicted position P (ti + 1) given their respective physical magnitudes. As indicated above, the control module MCM is responsible for causing the display medium SA to display at least one piece of information corresponding to the characteristic (s) of one of the groups, chosen according to the number of target people it groups compared to those of other groups. But, it can also make its choice based on minimum quota and / or maximum information that must be displayed 20 over a given period. Indeed, the final selection of the advertising poster to be selected can be made according to a minimum quota of posters that should be displayed over a given period (for example over a day) to avoid discriminating against certain advertisers who may to be poorly represented 25 and / or to respect certain contractual commitments with them. These quotas are for example defined in a quota table stored in a memory of the SS service server. Thus, to use the example presented in the preceding table, if several successive determinations have resulted in the selection of the same poster Ai (same result (female population of socio-occupational category A)), then the control module MCM must check whether minimum / maximum quotas have been defined. If this is the case, the control module MCM must select another group (for example that 2906626 associated with the distribution the second largest) and generate a display command designating the poster Ai associated with this group in the table. RCM (if his personal quota has not already been reached). FIG. 7 illustrates a nonlimiting example of a day information display quota table in the case of a display medium SA containing three posters A1, A2 and A3, respectively for three displays A1 ', A2 'and A3'. Each time a display Ai of the display medium SA is displayed, its effective display time is counted down by the maximum display time recorded in the quota table. When an Ai poster has been displayed for an effective duration greater than or equal to its maximum display time, it can no longer be displayed for the current period. On the other hand, when the given period (here the day) has expired, several situations can appear: the manager of the service server SS can memorize new data in the quota table, it can be decided, in the absence from any outside intervention, to reset the display times to their respective initial values, - it may be decided to store new advertising information corresponding to new advertisers and reset the display times to their respective initial values for the new advertisers. advertisers for whom the information has not been changed. It will be noted that the processing module MR of the display medium SA may comprise data transmission / reception means, preferably short-range, in order to broadcast at least in the first zone Z1 (in its position P ( ti + 1)) the information to display. Thus, each mobile terminal Tj of a target person can, if it is equipped with means for receiving short-range data, receive the information that is broadcast by the neighboring SA display medium. This significantly increases the likelihood that the target person will observe the information displayed. The short-range transmission technology that is used can be of any type, including RFID, Bluetooth, WiFi or infrared for example. Reference is now made to FIGS. 8 and 9 to describe a second embodiment of the system according to the invention. This second embodiment takes up almost all the elements (modules) constituting the system described above, while changing the location of a portion of them.

More specifically, the invention proposes to implement at least the MCM control module in a management device D housed in a display medium SA (as illustrated in Figure 8) or connected to the latter. In this case, the control module MCM receives from an MCL calculation module the definitions of the distributions of the target persons considered io as present in the first zone Z1 associated with its display medium SA and can implement the same functions as those described above with reference to Figures 1 to 7. It is thus at least responsible for causing the display medium to display at least one piece of information corresponding to the characteristic (s) of one of the groups of target persons in which the target persons likely to be present in the first zone Z1 in its predicted position P (ti + 1) have been distributed, according to the number of target persons it groups compared with those of the other groups, as well as possibly based on minimum quota and / or maximum information that must be displayed over a given period.

The group definitions and the local correspondence table between the groups and the available posters Ai can for example be transmitted by the service server SS and stored by the management device D in a memory MS4 accessible to the control means MCM.

As illustrated in FIG. 9, the management device D can also comprise an MCL calculation module responsible for distributing in the groups the target persons whose presence has been determined individually (as well as possibly collectively thanks to the predictive information). in the first zone Z1 in its predicted position P (ti + 1) by the locating means ML3 and ML4. In general, the calculation module MCL can implement the same functions as those described hereinabove with reference to FIGS. 1 to 7. The management device D can also comprise a time delay module MT responsible for making work on its possible MCL calculation module according to a chosen period, as previously described. In this second embodiment, the SS service server can be simplified since it no longer needs to understand a centralized control module. It now comprises the correspondence module MCR storing the correspondence table between the group definitions and the posters Ai that can be displayed by each display medium SA of the management system, the optional definition module MD making it possible to define the groups to be defined. from the profiles, and the first memory MS1 responsible for storing the profiles of the target persons. This second embodiment is particularly well suited, although not limitatively, to the case where the presence detection is carried out in each management device D for the first zone Z1 of its display medium SA.

Indeed, and as illustrated in FIG. 9, the management device D can comprise a part of the locating means ML4, the other part ML3 of these locating means equipping at least some of the target persons and the possible vehicle VT. (including the display medium SA), for example inside their mobile terminal Tj.

More specifically, the ML3 portion consists of data transmission modules, preferably short-range. Each ML3 data transmission module equips a target person and is responsible for transmitting radio signals that are representative of the identity of that target person. The management device D then comprises a data reception module MER for capturing the radio signals emitted by the neighboring ML3 data transmission modules in order to communicate the data they comprise to the part ML4 of the location means. The short-range transmission technology that is used can be of any type, including RFID, Bluetooth, WiFi or infrared for example. The ML4 part of the locating means is therefore responsible for estimating the distance separating the display medium SA, in its position P (ti) (since it receives the message at time ti), from the target person whose the data transmission module ML3 emitted a radio signal received by the reception module MER. Knowing the definition of the perimeter of the first zone Z1 and its predicted position P (ti + 1), it can then determine whether the target person who transmitted the received radio signal is likely to be located in the first zone Z1 in its predicted position P (ti + 1). If this is the case, the ML4 portion stores the identifier of the target person that is defined by the data of the received radio signal. He can then communicate this identifier to the calculation module MCL of his device D so that it takes into account in its distribution. This therefore requires that the MCL calculation module have access to the memory where the identifiers of the target persons are stored in correspondence of their respective profiles. As illustrated in FIG. 9, the device D may comprise a memory MS5 intended to store the identifiers of the target persons in correspondence of their respective profiles. This memory MS4 is for example supplied with data by the operator of the mobile network RM, or by the service server SS. But, as a variant, it is conceivable for the calculation module MCL to provide the mobile network RM with the identifiers of the detected target persons so that it transmits back to it the definitions of the profiles which are respectively associated with these identifiers.

Note that in this second embodiment, it is not useful for the management system to include a calculation server SC. But, we can consider a variant in which this can be useful. Indeed, in order to avoid the transfer of partially confidential data between the mobile network RM and the management devices D, it is conceivable that the latter do not comprise a calculation module MCL of decentralized type, but that a module of centralized calculation is provided in the calculation server SC, as described above with reference to Figures 1 to 7. In this case, each device D must transmit to the calculation server SC the identifiers of the target persons detected so that it proceeds to the 30. distribution then addresses this distribution to its MCM control module. It can also be envisaged that the management devices D do not comprise a detection module ML4 of decentralized type, but that a centralized ML2 part of the locating means is provided in the calculation server SC, as described above with reference to the In this case, the mobile terminals Tj of the target persons must be equipped with a satellite positioning module ML1 (as previously described with reference to FIGS. 1 to 7) and no longer with a module 5 of FIG. short-range ML3 data transmission. It will be noted that in this second embodiment, as in the first embodiment, the transmission / reception module MER of the management device D can be arranged to broadcast at least in the first zone Z1 (in its predicted position P (ti +1)) the information to display. Thus, each mobile terminal Tj of a target person may, if equipped with short-range data receiving means, receive the information that is broadcast by the neighboring SA display medium. This significantly increases the likelihood that the target person will observe the information displayed. Furthermore, at least in the case of the first embodiment, it can be envisaged that one of the display media SA of the management system is responsible for receiving for it and for other display media messages containing the display commands (as well as any definitions or descriptors of the information to be displayed) from the SS service server, and that it is responsible for broadcasting them by radio waves).

In a variant, it is possible to envisage a mode of transmission (propagative) step by step of the messages containing the display commands (as well as any definitions or descriptors of the information to be displayed) coming from the service server SS. In one case as in the other, the transmission and reception 25 may for example be done on a given band (for example VHF), the transmission being further TDMA mode synchronized to the GPS pulse, for example. The reception can be done continuously, each message then containing the references of the display medium ensuring the relay and the data broadcast.

This mode of operation can also be used to modify the information stored in the SA display media or the descriptor-information matches, particularly when they include a digital display screen. This information may, for example, be provided by means of a short-range transmission technique by a technical agent who travels in a vehicle equipped with a discount station. In the foregoing, there is described an exemplary implementation of the invention in which a single display medium SA was mounted on a vehicle VT. But, the vehicle VT may comprise at least two distinct faces on which can be mounted two display supports SA1 and SA2 respectively attached to the first zones Z1 and Z1 'distinct which follow its trajectory TR. In this case, the location means ML1 and ML2 (or ML3 and ML4) are responsible for determining the presence in the given time interval of target persons in each of the first zones Z1 and Z1 '. For its part, the calculation module MCL is responsible for distributing in a first set of groups EG1 the target persons whose presence has been determined in one of the first two zones Z1 or Z1 ', and in a second group of groups. EG2 (not necessarily identical to the first EG1) the target persons whose presence has been determined in the other of the first two zones Z1 'or Z1. In addition, the control module MCM is responsible for causing each of the two display supports SA1 and SA2 to display at least one piece of information that corresponds to the characteristic (s) of one of the groups of the corresponding set EG1 or EG2, chosen according to the number of target persons it groups compared with those of the other groups of the same set EG1 or EG2. All or part of the various modules constituting the management device D, the service server and the calculation server, according to the invention, can be implemented in the form of electronic circuits, software (or computer) modules, or a combination of circuits and software. The invention is not limited to the embodiments of management system, management device, service server and calculation server described above, only by way of example, but encompasses all variants that may consider those skilled in the art within the scope of the claims below. 34
