Abstract

The method for identifying at least one object (6, 8) belonging to a list of objects selected from a larger set of objects present in a store comprises an automatic comparison stage (146) for a list identifier contained in the memory of a mobile terminal with a list identifier contained in the memory of an electronic tag which is the closest to said terminal in order to determine if the identifiers of the list match, and, if the list identifiers do match, an automatic activation stage (148) for an operation (150) in which the object associated with said electronic tag is presented in order to indicate to a third party that said object belongs to the list corresponding to the list identifier recorded in the memory of the mobile terminal.

Description

Method and system for identifying an object belonging to a list of objects and information recording media for the execution of the method.

The invention relates to a method and a system for identifying at least one object belonging to a list of objects selected from a larger set of objects present in a store. The invention also relates to information recording media containing instructions for implementing the identification method.

More specifically, the invention relates to an identification method in which each object is associated with an electronic label carried by the object itself or by a gondola for presenting this object, each electronic label being equipped with a memory containing an identifier of the object with which it is associated.

Such methods prove to be particularly useful in the context of the consultation of objects inscribed on a list of objects to be purchased in one or more stores. Such a list is, for example, known by the term "wedding list", when this list relates to the gifts to be offered to a future married couple.

Currently, in order to establish such a wedding list, the bride and groom walk around the shelves of a department store and note on a notebook the reference of each item that will be entered in their wedding list. Then, once the wedding list has been established, third parties who wish to offer a gift to the bride and groom must obtain this wedding list and identify themselves in the aisles of the department store the items referenced on the wedding list, in order to be able to choose them.

Identifying each item on the wedding list in the store is long and tedious. Indeed, it requires the manual comparison by a third of the reference of each item registered on a label in the store, with the or each reference registered on the wedding list.

The invention aims to overcome this drawback by proposing a more user-friendly identification method for at least one object belonging to a list of objects. The subject of the invention is therefore a method of identification as described above, characterized in that it comprises: a) for the or each object belonging to a list, a step of recording in the memory of the electronic label associated with this object an identifier of the list, b) a step of automatic determination of the electronic label la nearest being equipped with a memory containing a list identifier. c) a step of automatically comparing the list identifier contained in the memory of the mobile consultation terminal with the list identifier contained in the memory of the electronic tag closest to this terminal, so as to determine whether these list identifiers match, and, d) only if these list identifiers match, a step of automatic activation of an operation of presentation of the object associated with this electronic label so as to indicate to a third party that this object belongs to the list corresponding to the list identifier recorded in the memory of the mobile consultation terminal.

In the above method, the objects appearing on a list drawn up by a user are each associated with an electronic tag in which an identifier of this list is recorded. Then, when a third party wishes to consult this list established by the user, he must have a mobile consultation terminal in which this identifier of the list of the user is registered and walk around the shelves of the store with this. mobile terminal. In this process, steps b), c) and d) are automatically carried out as the third party moves the consultation terminal in the aisles of the store. Therefore, each time the third party passes near an electronic label containing an identifier of the user's list, the object associated with this electronic label is automatically presented to it. Thus, the third party no longer has to manually compare the references written on the object labels with the references written on a list of objects selected by the user. This process is therefore simpler, and reduces the risk of errors.

According to other characteristics of the process according to the invention:

- step b) is preceded by step c) automatic establishment of a direct wireless transmission link between the terminal consultation mobile and each electronic tag near this terminal, and step b) includes an operation for selecting the wireless link established automatically with the closest electronic tag among the various links established during step e ), - step c) comprises an operation of transmitting the list identifier contained in the memory of the nearest electronic tag to the consultation terminal by means of said wireless link established automatically during the 'step e) and selected during step b); to reserve an object presented during the presentation operation, the method includes a step of automatically registering the identifier of the object presented in a list of reserved objects;

- It includes a step of automatic construction of a list of objects still available among those initially present in the list corresponding to the list identifier from the list of reserved objects and this initial list of objects;

the initial list of objects being recorded on a remote server connected to the consultation terminal by means of a long-distance information transmission network, the method comprises a step of transmitting the list of reserved objects to this remote server via said wide area network;

- initially to build the list of objects, the method comprises: a step f) of automatic determination of the electronic label closest to a mobile selection terminal, this mobile selection terminal being equipped with a memory containing a identifier of a list, and for the or each object to be inscribed on this list, a step g) of automatic reading of the identifier of the object, contained in the nearest electronic tag and of registration of this identifier in said list;

the list of objects being recorded on a remote server connected to the mobile selection terminal by means of a long-distance information transmission network, the method comprises a step of transmitting the or each object identifier to subscribe to the list, to this remote server via said long distance network. The invention also relates to an information recording medium, characterized in that it includes instructions for the execution of a method according to the invention when said instructions are executed by the consultation terminal L ' Another subject of the invention is also an information recording medium, characterized in that it includes instructions for the execution of a method according to the invention when said instructions are executed by the selection terminal.

The invention also relates to an information recording medium, characterized in that it includes instructions for the execution of a method according to the invention when said instructions are executed by the remote server.

The subject of the invention is also a system for identifying at least one object belonging to a list of objects selected from a larger set of objects present in a store, comprising electronic labels associated with each object and carried by the object itself or by a gondola for presenting this object, each electronic label being equipped with a memory containing an identifier of the object with which it is associated, characterized in that the system comprises: a) for the or each object belonging to a list, an electronic label associated with this object equipped with a memory in which is recorded an identifier of the list to which the object belongs in addition to the identifier of the object with which it is associated, b ) a mobile consultation terminal equipped with a memory containing a list identifier, c) means for automatically determining the electronic label of the most close to the mobile consultation terminal, d) means for automatic comparison of the list identifier contained in the memory of the mobile consultation terminal with the list identifier contained in the memory of the electronic tag closest to this terminal , so as to determine whether these list identifiers correspond, and means for automatic activation of an operation presentation of the object associated with an electronic tag whose list identifier corresponds to that registered in the consultation terminal, so as to indicate to a third party that this object belongs to the list corresponding to the list identifier registered in the memory of the mobile consultation terminal.

The invention will be better understood using the following description, given solely by way of example and made with reference to the drawings in which:

FIG. 1 is a schematic illustration of the architecture of an identification system of an object belonging to a list of objects according to the invention,

FIG. 2 is a flow diagram of a method for identifying an object belonging to a list of objects according to the invention and,

- Figure 3 is a schematic illustration of a variant of the system of Figure 1.

FIG. 1 represents a system allowing a simple identification of all the objects belonging to the same list of objects. This system is designated by the general reference 2.

System 2 includes a store 4 for selling objects. To simplify the illustration of Figure 1, only two objects, 6 and 8 have been represented inside this store. The object 6 is, for example, a book on which is fixed an electronic label 10. The object 8 is here, by way of example, a vase installed on a gondola 12 for presenting this vase. The gondola 12 carries an electronic label 14 corresponding to the vessel 8. The electronic labels are conventional and also known under the terms of "electronic tag" or under the initials "RFID" (Radio Frequency Identification). These labels are equipped with a memory so as to be able to store information relating to the object with which they are associated. Here, the labels each include an identifier of the object with which they are associated as well as other information relating to this object, such as its price. Note that for identical objects, the object identifier can be the same. These labels are, moreover, suitable for exchanging information with a radio transmitter / receiver via a short-distance radio wireless link conforming to the Bluetooth standard. Preferably, the electronic labels are here called active labels, that is to say equipped with their own source of energy. These active electronic tags have the advantage, on the one hand, of being able to initiate an exchange of information with a transmitter / receiver, and on the other hand, of being able to establish a radio link with the '' transmitter / receiver over a distance between 50 and 300 meters.

Conventionally, this store 4 is equipped with a local network 20 for transmitting information to which a local management server 22 and cash registers are connected. Here, only a cash register 24 has been shown to simplify the illustration.

A radio transmitter / receiver 25 conforming to the Bluetooth standard is also connected to this local network 20. The local server 22 is able, in particular, to manage the stocks of the store 4. For this purpose, it is able to communicate with each of the electronic tags associated with the objects via the transmitter / receiver 25 so as to read or record information in these tags. Furthermore, it is also able to communicate with cash registers 24 to receive from the latter, for example, the identity of the items sold.

The system 2 also includes several selection terminals and several consultation terminals. Here, to simplify the illustration, only a selection terminal 30 and a consultation terminal 32 have been shown.

The selection terminal 30 is intended to establish an electronic list of objects selected from among those present in the store 4. This terminal is mobile and movable by a human being. It includes an electronic calculator

33 connected to a short distance radio transmitter / receiver 34 conforming to the Bluetooth standard and to a long distance radio transmitter / receiver 36.

The transmitter / receiver 34 is able to establish a bi-directional link 40 for transmitting information between the terminal 30 and the or each label present near this terminal so as to be able to read and record information in these electronic labels. The transmitter / receiver 36 is, for its part, intended to communicate via a long distance network 42 for transmitting information with a remote server 44 via a wireless link 45. The network long distance 42 is, for example, the telephone network of a mobile operator.

The terminal 30 also includes a screen 46, a button. selection 47 and a loudspeaker 48 for presenting information to the user of the terminal 30.

The computer 33 of the terminal 30 is associated with a memory 50 capable of storing the information necessary for the execution of the method of FIG. 2.

The computer 30 is here a conventional programmable computer capable of executing instructions recorded on an information recording medium. To this end, the memory 50 includes instructions for the execution of the method of FIG. 2 when these instructions are executed by the computer 33.

Here, by way of example, all of the components of the terminal 30 are integrated into a mobile telephone or even into a personal digital assistant known by the term "PDA" ().

The consultation terminal 32 is intended to allow a simple identification of the objects belonging to a list of objects previously created among all the objects present in the store 4. For this purpose, the terminal 32 is capable of establishing a wireless link short distance 60 of information transmission with the electronic tags of the store 4 and a long distance wireless link 62 of information transmission with the remote server 44.

To have these capabilities, the terminal 32 similarly comprises the terminal 30 a programmable electronic computer 63, a short distance radio transmitter / receiver 64, a long distance radio transmitter / receiver 66, a memory 68, a screen 70, a button selection 71 and a loudspeaker 72. These elements having already been the subject of a description opposite the terminal 30, they will therefore not be described here in more detail.

Similarly to terminal 30, this terminal 32 is, for example, integrated into a mobile telephone or a personal digital assistant. The remote server 44 is intended to record each list of objects created from selection terminals, such as the terminal 30 and to manage the lists of objects recorded from information transmitted by the consultation terminals and by the cash registers. registers. To this end, the remote server 44 is associated with a memory 80.

The server 44 is produced from a conventional programmable computer capable of executing instructions recorded on an information recording medium. To this end, the memory 80 includes instructions for the execution of the method of FIG. 2 when these instructions are executed by the remote server 44.

Finally, in order to communicate with the consultation terminals, the cash register 24 is equipped with a short-distance wireless transmitter / receiver 84 conforming to the Bluetooth standard.

The cash register 24 is also connected via an information transmission link to the network 42 so as to be able to exchange information with the remote server 44. This information transmission link is, for example, a connection wired information transmission carried out from a modulator / demodulator or modem.

The operation of system 2 will now be described with the aid of FIG. 2.

Initially, each object in store 4 is associated, during a step

90 to an electronic label carried either by the object itself, or by the gondola for presenting the object. During this step 90, an identifier of the object with which it is associated is recorded in each of the electronic tags. This identifier is for example the product reference.

When a user wishes to establish a list of objects selected from those available in the store 4, they connect, in a step 92, to the remote server 44 using the terminal 30. Once the link 45 of transmission of information is established via the network 42 between the terminal 30 and the server 44, the user transmits his identity and his contact details to the server 44 so that the latter creates, during a step 94, an identifier for list of objects for this user. Initially, this identifier is associated with a empty object list. The list identifier is for example a file name in which the references of the objects forming part of the list will be recorded.

Once the identifier has been created, the server 44 transmits it, during a step 96, to the terminal 30. On receipt of this identifier, the terminal 30 saves it, during a step 98 in the memory 50.

Once the list identifier has been recorded in the memory of the terminal 30, the user then proceeds to a phase 100 of object registrations on his list. To do this, equipped with the terminal 30, it moves during a step 102, in the aisles of the store 4.

Permanently, during its movement, the terminal 30 automatically establishes, during a step 104, short-distance information transmission links between the transmitter / receiver 34 and there or each electronic tag located nearby, this is i.e. within range of transmitter / receiver 34.

During a step 105, the user brings the terminal 30 closer to the label of the object that he wishes to register on his list.

Then, from among the different wireless links simultaneously established, the terminal 30 automatically selects, in a step 106, the one which is established with the closest electronic tag. This selection is made, for example, on the basis of the power of the signals received, the signals received of higher power corresponding to the information transmission link established with the nearest electronic tag. For the remainder of the description, it is assumed that the label 10 is currently the closest to the selection terminal 30, so that, during step 104, the connection 40 is automatically established, and that, when in step 106, this link 40 was recognized as being the link with the nearest label. Consequently, the terminal 30 automatically links, during a step 108, the information contained in the label 10, then displays it on the screen 46, during a step 110. Thus, the user of the terminal 30 has information relating to the object to which the electronic label is closest at all times. The information read also includes the identifier of this object. To register this object on his list, the user presses, during a step 112, the selection button 47.

In response to this pressing of the button 47, the terminal 30 transmits, during a step 114, the list identifier contained in its memory 50 to the label 10, via the link 40.

On receipt of this list identifier, the label 10 stores in its memory, during a step 116, the list identifier received.

Then, the terminal 30 automatically establishes, during a step 118, the link 45 for transmitting information with the server 44 using the transmitter / receiver 36 and the network 42. Once this link 45 is established, the terminal 30 transmits to the server 44, during a step 120, the identifier of the object contained in the label 10 and the identifier of the list.

Upon receipt of this object identifier, the server 44 automatically registers it, during a step 124, in the list corresponding to the identifier of the list received.

Steps 102 to 124 are repeated for each object that the user wishes to register in his list. Thus, the saved list typically contains several identifiers of different objects selected by the user. Such a method for creating an electronic list of selected objects is particularly simple, since the user only has to walk around, equipped with the terminal 30 in the aisles of the store, bring the terminal 30 closer to the object he wish to select, and confirm their selection using button 47.

A potential buyer who wishes to consult the objects entered in the electronic list must have a consultation terminal and save in the memory 68 of this terminal the identifier of the list of objects that he wishes to consult. To this end, in the embodiment described here, a phase 130 of consulting the objects listed on an electronic list, begins with a step 132 of establishing the link 62 for transmitting information between the terminal 32 and the server 44 Once this connection has been established, the terminal 32 downloads, during a step 134, the identifier of the list that it wishes to consult. This list identifier to be consulted is recorded during a step 136 in the memory 68. Then, the buyer equipped with his mobile terminal 32 moves, during a step 138 in the aisles of the store 4.

Similarly to steps 104 and 106, the terminal 32 automatically establishes, during a step 140. short distance information transmission links with the nearby electronic tags, and selects, in a step 142, the information transmission link corresponding to the nearest electronic tag.

Here, it will be assumed that the electronic tag closest to the terminal 32 is the tag 14, so that the information transmission link selected is the link 60.

If the label 14 contains one or more list identifiers in its memory, then it or it transmits them during a step 144 to the terminal 32 via the link 60.

The terminal 32 then automatically compares, during a step 146, each list identifier received with that recorded in its memory 68.

If none of the list identifiers received does not correspond to that stored in memory 68, the method returns to step 138.

Otherwise, that is to say if at least one of the list identifiers received corresponds to that recorded in the terminal 32, the latter then proceeds to a step 148 of activating an operation 150 of presentation of the object corresponding to the buyer.

During this operation 150, the information concerning the object is read by the terminal 32 and displayed on the screen 70, while a beep emitted by the speaker 72 warns the buyer that the object corresponding to the 'closest tag belongs to the list you wish to consult.

If, after having consulted the information presented on the screen 70, the buyer wishes to acquire the corresponding object, he presses during a step 152, the selection button 71.

In response to the pressing of this button 71, the terminal 32 links, via the link 60, the identifier of the object contained in the label 14 and records, during a step 154, the identifier of the object read in memory 68. Thus, a list of reserved or purchased objects is created in memory 68. Then, if the buyer wishes to acquire other objects, he proceeds again to step 138.

Otherwise, he goes to the cash register 24 to pay for his purchases. Close to the cash register 24, the terminal 32 automatically establishes, during a step 158, a short-distance information transmission link with the cash register 24, via the transmitter / receiver 84.

Once this connection has been established, it transmits during a step 160, the list identifier and the list of reserved objects contained in its memory 68. The cash register 24 then automatically establishes, during a step 162, the invoice to be set from the object identifiers contained in the list of reserved objects received.

Once the invoice has been paid, the cashier 24 transmits, during a step 164, the list identifier and the list of objects reserved to the local server 22. The local server 22 then commands, during a step 166, clearing the list identifier in the memory of the labels associated with objects in the list of reserved objects. Thus, although the electronic label 14 has not been physically removed from the store 4, the object associated with this label 14 will no longer be presented during subsequent consultation phases as belonging to the list of objects selected by the initial user. This avoids the purchase in multiple copies of the same object registered only once on the list of objects, although the electronic label remains in place in the store 4 after the first purchase of this object .

In parallel with step 164, the cash register 24 automatically transmits to the server 44, during step 168, the list identifier and the list of reserved objects via the network 42.

The server 44, from the list of reserved objects transmitted by the cash register 24 and from the list of initially recorded objects, constructed during a step 170, a list of the objects still available. This list of objects still available is, for example, consultable via an Internet network, so that the person who created this list can know at all times the objects still available and the objects already purchased. FIG. 3 represents a variant of the system of FIG. 1 in which the magazine 4 additionally comprises a device 200 for locating the selection and consultation terminals 30, 32. This variant of the system 2 is designated by the general reference 202 The location device 200 is conventional, and implements, for example, a method for locating mobile terminals 30 _r 32 by triangularization.

To this end, the device 200 is formed of at least three short-distance radio transmitters / receivers conforming to the Bluetooth standard, each capable of communicating with the mobile terminals 30, 32. Here, to simplify FIG. 3, only one of these transmitters / radio receivers was shown. The information collected by each of these transceivers is processed in a conventional manner to determine the position of each of the mobile terminals inside the store 4. These transceivers are also connected to the network 20 so that the mobile terminals 30, 32 can exchange information with the electronic tags successively via the transceivers of the device 200, the network 20 and the transceiver 25. The operation of this system 202 is identical to that described with regard to FIG. 2, except for the fact that the determination of the electronic tag closest to the terminals 30 and 32 is not carried out by selection of the short distance information transmission link, having the strongest signal power. On the contrary, here, the distance between one of the mobile terminals and an electronic label is calculated from the geographic coordinates of the mobile terminal and those of the electronic labels present in the store 4.

In addition, in this variant, the exchange of information between the mobile terminals and the electronic tags is carried out only through the device 200, so that it is no longer necessary to establish direct wireless links. between mobile terminals and electronic tags. In particular, when a mobile terminal is brought closer to an electronic label, it is the device 200 which transmits to the mobile terminal the information relating to the object corresponding to the closest label.

In this variant 202, all of the steps of the method of FIG. 2 are adapted so that. the exchanges of information between the electronic tags and the ^" mobile ^" terminals are carried out each time via the device 200.

The systems 2 and 202 have been described here in the particular case where they have only one store 4. However, as a variant, the store 4 is replaced by several stores distributed in different geographic locations such as, for example, different cities.

The method of FIG. 2 has been described here in the simple case of a single list. However, the system described here is also capable of managing several lists simultaneously, either for the same user or for different users. In this case, it is important to note that the same electronic label can include several different list identifiers when the same object belongs to different lists.

In the system described here, the list identifier stored in the memory 68 of the consultation terminal is downloaded from the server 44. However, there are many other possibilities for recording in this memory 68 the list identifier that the 'we wish to consult. For example, in a particularly simplified version, this list identifier to be saved in memory 168 is simply entered by the buyer using a keyboard with which the terminal 32 is equipped. In systems 2 and 202, the presence a list identifier, corresponding to that registered in the consultation terminal, is only verified for the nearest electronic label. In another embodiment, the presence of the list identifier corresponding to the list identifier registered in the consultation terminal is verified, not only for the nearest electronic label, but also, for example, for the nearest 5, 10 or 20 electronic tags. Thus, the presentation operation 150 can be triggered in this variant, if at least one of the electronic labels in the nearest 5, 10 or 20 electronic labels contains the list identifier sought.
