Description

SET OF INTERCONNECTED OBJECTS IN PARTICULAR FOR

COGNITIVE SPORTS TRAINING AND ASSOCIATED SYSTEM

The invention relates generally to the field of computer-assisted physical activities and sports. More particularly, the invention relates to a set of interconnected objects for cognitive training in the practice of sport and physical activities. The invention also relates to a cognitive training system integrating at least one set of interconnected objects as mentioned above and to a method of operating the set of interconnected objects.

Research over the past two decades in the areas of neuroscience and cognition has shown that it is possible to train the human brain to improve a person's cognitive and motor skills, such as attention, perception, reasoning, decision making, coordination, responsiveness.

The results of this research have interesting applications in the field of physical and sporting activities, of course in performance training among high performance athletes, but also more generally in the general population, for example, for the well-being and maintenance of the motor skills of the elderly or people with disabilities, the prevention of health risks linked to a sedentary lifestyle, or,

Children's learning and motor development, and in certain occupations where situational awareness, rapid decision-making and precise motor control are of great importance.

Computer tools for cognitive sports training have been developed and are commercially available.

Thus, it is known the Intelligym software (registered trademark) which works on a conventional computer and is based on a video game approach, with reduced scenarios of game situation. The NeuroTracker system (registered trademark) calls upon immersion of the person, equipped with 3D glasses, in a virtual reality scenario displayed on a screen.

Furthermore, the method which is mental chronometry is an imposed tool in cognitive and experimental psychology and in neuroscience. The key variable in mental chronometry is the reaction time which corresponds to the duration of the information processing processes taking place in the human brain between a stimulus and the production of a motor response. The reaction time begins with the presentation of the stimulus, for example, visual or auditory, and ends with

The execution of a movement.

The stimulus, to which the subject must respond as quickly and as precisely as possible, is preceded by a warning signal which informs the person of the imminent onset of the stimulus. When the instruction to react as quickly as possible, while avoiding errors, is respected, the time which elapses between the stimulus and the execution of the motor response corresponds to the reaction time which represents the minimum time required to perform the set of operations leading to the appropriate response.

Mental chronometry involves numerous tests comprising simple tasks and tasks with choices which allow, by a subtractive method, to decompose a reaction time into a detection time, a discrimination time, a time to select the appropriate response and a engine time.

By American patent US6435878B1, an interactive computer program is known which uses mental chronometry for the measurement and analysis of cognitive skills. The computer automatically presents a sequence of visual and auditory stimuli. The program measures reaction times to stimuli, adjusts stimulation parameters and displays the scores obtained for analysis. The program compiles the history of test results, provides an overall assessment of the performance performed and comments on the results. The difficulty of the tests is adjusted according to the scores obtained in order to develop cognitive skills. The program assesses physical reaction time, perception thresholds, level of attention, speed, efficiency and capacity of information processing by the brain and basic cognitive processes including memory, access memory and decision-making speed. The disclosure of patent US6435878B1 is limited to a computer program with which the user interacts in a static position with usual means such as the computer keyboard or a video game controller. This software tool is dedicated to cognitive development in general and is not designed for cognitive sports training.

The tools of the state of the art described above are limited in their possibilities of use. They are spatially localized and require the physical presence of the actors in the same place. In addition, these tools are not particularly designed to facilitate cognitive training for several, nor to allow motor responses in the form of execution of tasks or physical exercises with movements and displacements of significant magnitude, and even less for outdoor use, for example on a soccer field. Group practice is likely to induce a favorable playfulness and increased cohesion, for example, in a sports team.

In cognitive training sessions, large-scale motor responses would provide significant physical activity which can only be beneficial for good physical condition.

Referring to Figure 1, there is now described a first example of deployment of a cognitive sports training system comprising a set of interconnected objects according to the invention.

The set of interconnected objects here comprises a display unit CUB and several wireless electronic beacons RI, DI and R2, D2.

It should be noted that the invention is feasible with interconnected objects of large, medium or small sizes. Thus, the CUB display unit may have a height, for example, of a few tens of centimeters for domestic use or a much more substantial height, for example several meters, for use on a sports field.

The display unit CUB is connected by a data communication link L _S c to a computer server MS. Such a computer server MS can consist of one or more computers comprising a processing unit, such as a microprocessor for example, in cooperation with memories and communication means allowing it to interact with other electronic entities via one or more links. wireless or wired. The computer server MS can thus be connected to an IP communication network such as the Internet. The data communication link

Lsc is a wireless link in the embodiment of Figure 1. Generally, it will be noted that the data communication link L _S c between

The display unit CUB and the server MS may be a wireless link or a wired link. Thus, this link L _S c may for example be established through a cellular mobile telephone network such as GRPS (General Packet Radio Service networks, according to terminology anglorespectively third or fourth generation of data communication network standards dedicated to interconnected objects wireless such as the Sigfox network (brand

Ethernet or ADSL terminology

Ethernet or an IEEE group (registered trademark) or (Asymmetric Digital Wi-Fi link,

802.11 in particular.

via through a

Subscriber Line a router link, according to wire defined by the standards of

As shown in Figure 1, the display unit CUB is interconnected with the tags RI, DI and R2 through wireless data communication links L _R i, L _D i and L _R2 , respectively.

The CUB visualization unit has the particular function of displaying stimuli for cognitive training exercises on visualization surfaces. Depending on the applications, a display surface will have the form of a simple panel of light emitting diodes LED (lightemitting diode, according to English terminology) for the display of messages or pictograms of stimuli, or a resolution screen more high for displaying stimuli images.

The CUB display unit is presented here in the form of a cube comprising four display surfaces E1 to E4 of which only the display surfaces E1 and E2 are visible in FIG. 1. In general, a shape in cube or in regular tetrahedron will be well suited for the CUB visualization unit which will have a lower face forming a base for the support on the ground as a support and lateral faces comprising the stimuli visualization surfaces.

The plurality of viewing surfaces allows several participants such as participants J1 and J2 described in FIG. 1, and sometimes hereinafter designated J, in an undifferentiated manner for the sake of simplification, for cognitive training sessions around the same CUB display unit. Due to the presence of this plurality of viewing surfaces, a single viewing unit CUB can be used for separate cognitive training sessions taking place simultaneously.

In addition to allowing several participants J around the same visualization unit CUB, the presence of different visualization surfaces is advantageous for certain types of exercise, in particular those aiming to evaluate the level of cerebral laterality of a participant J. For this, the CUB unit must include at least two viewing surfaces that can be seen simultaneously by the same participant. The two viewing surfaces will be exposed differently so as to induce sensitive visual discrimination between the two eyes of the observer. Thus, a first viewing surface is located to the right of an observer, or his field of vision, to be seen primarily by his right eye and the second viewing surface is located to the left of the observer to be seen primarily by his left eye. More generally, in order to obtain this vision of the two viewing surfaces by an OBS observer, as shown in

Figure 2, the first SI and second S2 viewing surfaces will be located in separate planes at the intersection PI, P2, and will form an angle between them

HP audio speakers, or more generally any other sound reproduction means, can be accommodated here in uprights forming edges of the display unit

CUB. Such HP speakers are intended for

The emission of auditory stimuli. Note that the function of these speakers

HP can also be filled with headphones (not shown) worn by participants

J. These headphones may prove essential in the case of simultaneous sessions using auditory stimuli, to avoid participants J being hindered by a session which is not their own.

The CUB display unit includes an electronic control unit 1, shown in Figure

3, which will be described in detail below.

Human-machine interface means TO in the form of keys and a wired connection USB port, for example compliant with the USB standard (Universal Serial Bus, according to terminology or any other alternative serial or parallel transmission technology), can be integrated in the CUB display unit The buttons are provided for the on / off control of the CUB display unit as well as for a basic control dialog with

The electronic control unit 1, for example through a drop-down menu of which

The display can be restored by one of the display surfaces E1 to E4, sometimes simply designated E, in an undifferentiated manner with regard to other even display surfaces, in the rest of the document, for the sake of simplification. The port

USB can be used for the connection of a keyboard and for downloading into the electronic control unit 1, for example from a storage memory, advantageously electrically erasable for example according to technology or English terminology "Flash memory" or any other equivalent rewritable data memory, of a cognitive training session comprising one or more sequences of exercises.

The cognitive training session is for example pre-programmed for one or more participants J. Le port

USB can also be used to execute configuration or troubleshooting routines.

It will be noted that the display unit CUB can comprise, according to a preferred embodiment, sealing means to ensure protection against humidity and rain during outdoor sessions. These sealing means may in particular comprise a protective cover covering the man-machine interface means TO and the USB port. The watertightness of E screens and HP audio speakers must also be ensured.

The wireless data communication links L _R i,

L _D i and L _R 2 are typically communication links by radio wave or more generally by electromagnetic wave for example, by the implementation of communication protocol (s) of Bluetooth type, typically of the type

Bluetooth 4.0 allowing a range of the order of a few tens to a few hundred meters with low consumption. In the embodiment of Figure 1, the data communication link L _S c is established through a cellular low-speed data communication network for wireless interconnected objects, such as the Sigfox or LoRa network, comprising gateways with the internet network to which the MS server is connected. In certain applications requiring higher speed data communications, the data communication link L _S c will be established directly through the internet network, for example, through an Ethernet or ADSL router via an Ethernet wired link or a Wi link -Fi or equivalent.

According to the invention, the tags are of two types, a first type called "reaction" designated by the radical R and a second type called detection "designated by the radical

D. In the configuration example in Figure 1, the tags RI and R2 are reaction tags and the tags DI and D2 are detection tags. For the sake of simplification, we will be able to designate undifferentiated by the reference

R, any reaction tag among the RI tags,

R2, R1A,

R2A, R2B, described by FIG. 1 or by FIG. 7. In the same way, we can subsequently designate in an undifferentiated manner by the reference

D, any detection tag among the tags

Dl, D2, D1A,

D2A, D2B, described by the figure or by the

Figure 7.

Finally, we will designate a data communication link established between

The CUB display unit and a reaction tag R by the radical

L _r , such as the links L _R i and L _R2 described in FIG. 1. A data communication link established between the display unit CUB and a detection beacon D may in turn be designated by the radical L _D , such the links L _D i and L _D 2 also described in Figure 1.

The reaction tags R are used to measure the reactions to the stimuli of the participants J. The tags R comprise means of detection / measurement of movement and are intended to be touched, taken and / or moved by the participants J. They will therefore preferably have shapes that facilitate their gripping. Handles or gripping buttons may be provided for this purpose. The reaction tags R include an electronic circuit 2, shown in Figure 4, which will be described below in detail.

According to a particular embodiment, the reaction tags R are produced in the form of a waterproof case that can be integrated into a garment, an armband, a bracelet or an accessory intended to be worn by the person during cognitive training exercises. Thus, for example, the reaction tag R can be carried in a pocket of the garment, or else hung on a Velcro strip (registered trademark) thereof or in any other way. Means of electrical charging by induction, described below with reference to Figure 4, may be provided in the tags and will facilitate sealing thereof due to the absence of electrical charging socket.

The detection beacons D essentially serve as markers for movements to be executed by the participants J with their respective reaction beacons R. Detection beacons D may be in various forms and have different functional architectures.

Thus, the detection tags D may, for example, have the shape of a stake to be planted on the ground, of a self-adhesive box to be fixed on a wall or any other shape.

In the example of Figure 1, the detection tags D are of two types, represented by the tag Dl and the tag D2.

The Dl beacon is a configurable beacon, that is to say, a beacon having an electronic architecture which allows a configuration as a detection beacon D or as a reaction beacon R. A configuration firmware, downloaded in the Dl beacon, more precisely in a memory cooperating with a microcontroller of said beacon Dl and whose execution or interpretation by said microcontroller, causes and / or fixes the operation of the latter as a detection beacon.

A detection beacon D can also have a simpler electronic architecture. This is the case of the detection tag D2 in FIG. 1. The detection tag D can then be presented, for example, in the form of a passive radio-identification transponder such as a passive RFID tag. ("Radio frequency identification" according to Anglo-Saxon terminology) which is supplied by the radio signal emitted by an RFID reader integrated into a reaction beacon R.

Typically, a reaction tag R can be assigned to each participant J. On the other hand, several detection tags D can be used by the same participant for a cognitive training exercise in a session.

Generally, the exercises proposed in the cognitive training sequence include simple movement exercises and more or less complex movement exercises, hereinafter called "compound movement exercise". Simple movement exercises are performed by participant J only with his reaction tag R. For compound movement exercises, the reaction tag R and one or more detection tags D will be used.

The tag reaction R is designed to be in interaction with movement of participant J and provides of the measurement data thereof. As illustrative, consider a exercise of

simple movement which only requires the use of the reaction tag R in order to measure a reaction time according to the method of mental chronometry. In this exercise, the stimulus displayed on a screen E of the CUB display unit, stimulus which comes after a warning signal, is for example "grab the tag R and place it at the end of your arm above your head ". The instant when participant J takes hold of the tag R is an event which is detected by it and causes the start of the transmission of movement measurement data to the display unit CUB, via a radio communication link L _R among the links referenced L _R i and L _R 2 described by way of example in FIG. 1, according to the tag R concerned. The display unit CUB then triggers a counting of an execution time TE of the exercise. The correct execution of the movement is followed until its completion thanks to the measurement data transmitted by the beacon R. The end of the movement is an event which is detected in the transmitted measurement data and the CUB display unit stops counting of the TE execution time. The execution time TE thus measured is the result of this exercise.

Still by way of illustration, let us now consider a compound movement exercise which requests the use of the reaction beacon R and two detection beacons Da, Db (not described in Figure 1), which are both coupled to the beacon of reaction R.

In general, the term “coupled tags” is understood here to mean that tags can be recognized as cooperating in the same exercise by reading one of the tags from an identifier stored in the other tag. The terms “identification coupling” will also be used in the following description.

In this exercise, the stimulus displayed on a screen E of the display unit CUB is for example “grasp the tag R and place it next to the tag Db after having passed through the tag Da”. The instant when participant J takes hold of the beacon R is an event which is detected by it and causes the start of the transmission of movement measurement data to the display unit CUB, via the communication link L _R. The display unit CUB then triggers a counting of the execution time TE. The execution of the movement is followed until its completion thanks to the measurement data transmitted by the beacon R. Proximity detection / identification means, described below, are included in the beacons. The passage through the Da tag is an event which is detected when the participant J with his R tag passes near the Da tag and a passage data is then produced. Depending on the type of the Da tag, the passage data is transmitted to the display unit CUB either by the Da tag itself which has its own communication link L _D (this is for example the case of the tag DI described by FIG. 1 which communicates with the display unit CUB via the communication link L _D i), or, when the beacon Da does not have a communication link (this is for example the case of the beacon D2 described in Figure 1), by the tag R via its communication link L _R. The arrival of the participant J with his tag R at the level of the tag Db is an event which is detected by the proximity of the two tags R and Db, and an arrival datum is then produced. The arrival data is transmitted to the display unit CUB in the same way as the passage data, depending on the type of the beacon Db. The display unit CUB then triggers an end of counting of the execution time TE.

It will be noted that the detection of an event “passage of beacon D” or “arrival on beacon D” by proximity detection can only intervene insofar as the R and D beacons can be recognized as being coupled. In the invention, the need for identification coupling results from the fact that several participants J coexist around the same display unit. Participants J are likely to have the wrong detection tag D when performing the exercises. During the course of the exercises, the event data are transmitted to the display unit CUB, typically in packets or messages, with identification data which make it possible to associate the events with the exercises and the sessions concerned.

The result of an exercise could for example be displayed on a screen E at the end of the exercise for quick feedback (or “feedback” according to Anglo-Saxon terminology) to participant J. The result could also be stored in the CUB display unit for display on the screen E of all the results at the end of an exercise sequence or of the cognitive training session. In this embodiment, all the data from the different sessions carried out by each participant J and the results obtained are stored in a history stored in the server MS. In order to feed this history,

The CUB display unit can transmit the result data to the server for each session

MS through the data communication link L _S c The history of the sessions carried out may be accessible, for example, through a remote application platform (not hosted by said server

MS. In this example, dedicated user accounts are assigned for this to participants J and their trainer. Analytical and statistical tools are accessible through the application platform to exploit a participant history or a plurality of participant histories in order to assess the progress of a participant or a group / team of participants. This exploitation of the histories may also take place by means of a dedicated application installed or installed in a personal computer, a tablet or a smart mobile phone also known by the Anglo-Saxon name "smartphone" after downloading the historical data in a like electronic device.

Cognitive training sessions can be prepared (choice of exercises, scheduling of exercise sequences, etc.) and programmed in advance, for example by a team coach, using the tools available through the application platform or in the dedicated application installed on computer, tablet or smartphone. The launch of a cognitive training session is triggered after the downloading to the display unit CUB of a session file F_SES containing all the data necessary for the course of the session. The downloading of a session file F_SES into the display unit CUB can be done through the communication link L _S c <by controlling this download from the remote application platform by means of a smartphone for example. Downloading an F_SES session file into the CUB display unit can also be done directly from the dedicated application installed in the smartphone, which is then placed in short-range wireless communication, for example of the Bluetooth type ( registered trademark), with the CUB unit. The USB port of the CUB display unit can also be used to download a session file F_SES contained in a removable storage medium such as a key using the standardized USB communication format comprising a flash type memory. The drop-down menu keys of the human-machine interface TO can then be used to control the downloading of the file F_SES from such a removable storage medium, once this has been inserted into the port referenced USB in FIG. 1 of the CUB display unit.

Referring now more particularly to FIG. 3, a preferred but nonlimiting example of an electronic control unit 1 included in a display unit according to the invention is described below in detail, such as the display unit. CUB visualization presented in Figure 1.

The electronic control unit 1 comprises a control unit 10, an internal communication bus PB ^ c, radio transmitter / receiver modules 11 and 12, a power supply unit 105 and a time base or clock ( not shown).

The control unit 10 is typically in the form of a microcontroller comprising, in a conventional manner, a microprocessor μΡ, a non-volatile data memory 100 of E2PROM type (for “Electrically-Erasable Programmable Read-Only Memory” according to a English terminology) containing an elementary BIOS system managing the inputs / outputs of the microcontroller, a volatile data memory 101 of SRAM type (for “Static Random Access Memory” according to English terminology) constituting the working RAM of the microprocessor μΡ, a non-volatile program memory 102 of Flash type, input / output interfaces 103, 104 and a wired USB communication port.

The program memory 102 contains an operating program OP_EXP which is executed by the control unit 10 for the implementation of the method of operating the set of interconnected objects according to the invention. The OP_EXP operating program is described in detail later with reference to Figure 6.

The input / output interface 103 is a data input / output port which is configured with a software layer for operation as a type I ² C bus interface. The standard I ² C (acronym for "Inter- Integrated Circuit ”according to English terminology) defines a synchronous serial communication bus. Interface 103 is connected to the internal communication bus PB ^ c of type I ² C.

The input / output interface 104 is an input / output port to which the keys PW, UP, DW and EN of the man / machine interface means TO are connected, as well as a light-emitting diode LED forming an indicator light. power up. The keys PW, UP, DW and EN are respectively the on / off key of the CUB display unit, the up and down keys of the command drop-down menu and the validation key of choice of the drop down menu.

The transmitter / receiver module 11 is here a radio communication module which is compatible with a cellular data communication network for interconnected objects, such as the Sigfox (registered trademark) or LoRa (registered trademark) network. The transmitter / receiver module 11 comprises in particular an integrated antenna of “microstrip” type, or “stripline” in English, and an interface

I ² C for connection on the internal communication bus

PBi2C ·

For example, the “MultiConnect xDot” module sold by the company MultiTech Systems (registered trademark), having an I ² C interface, could be used for the transmitter / receiver module 11. The communication link L _S c with the server MS is established through this transmitter / receiver module 11.

The transmitter / receiver module 12 is here a Bluetooth 4.0 radio communication module. Similarly to the module 11, the transmitter / receiver module 12 comprises in particular an integrated antenna of “microstrip” type and an I ² C interface for connection to the internal communication bus PB _i2c . For example, a module from the “I ² C Bluetooth Smart Modules” range, in 4.0, marketed by the company Panasonic (registered trademark), could be used for the transmitter / receiver module 12.

The transmitter / receiver module 12 is used in particular for the various Bluetooth communication links L _R and L _D established with the R and D tags, as well as for the Bluetooth communication link, indicated above, with a computer, tablet or smartphone. The communication network, materialized by the various communication links previously mentioned, in particular

L _r and

Ld, here authorizes bidirectional communication in point-to-point mode between the display unit CUB and the beacons R,

D, and the computer, tablet or smartphone. A standard seven layer OSI protocol can be implemented to allow multiple communications

Bluetooth simultaneously.

As shown in Figure 3, in this embodiment, the four screens El to E4 and the HP audio speakers of the display unit CUB are also connected to the internal communication bus PB ^ c through integrated interfaces I ² C .

The power supply unit 105 comprises a rechargeable battery 105b and alternating current / direct current (AC / DC) and direct current / direct current (DC / DC) converters, said converters not being shown in FIG. 3. The converters produce the various DC voltages necessary for the operation of the CUB display unit. The battery 105b is typically a lithium-ion type battery, which should allow sufficient operating autonomy. Means of electric charge by induction, not shown in Figure 3, may be provided, as well as possibly an electric power cable, also not shown in said Figure 3, to connect the power supply unit 105 to the mains electric alternative.

With reference now more particularly to FIG. 4, a preferred but nonlimiting example of an electronic circuit 2 of a configurable beacon is described below in detail, comprising a mode in which said beacon operates as a reaction beacon R hereinafter "reaction mode" and another mode in which it operates as a detection beacon D, hereinafter called "detection mode".

The electronic circuit 2 includes a control unit

20, an internal communication bus BB ^ c of the type

I ² C, a module 21 comprising an accelerometer and / or a gyroscope, a transmitter / receiver module 22 advantageously of the radio frequency type, a radio-identification module 23 and a power supply unit 24.

The control unit 20 is typically in the form of a microcontroller comprising, conventionally, a microprocessor μΡ, a non-volatile data memory 200 of the E2PROM type, a volatile data memory 201 of the SRAM type, a program memory non-volatile 202 of FLASH type containing a B_PROG tag firmware, input / output interfaces 203 (203a, 203b), 204 and a USB communication port _b .

The B_PROG beacon firmware includes a B_CONFIG configuration module and a B_DETECT detection module. The B_CONF module notably performs the configuration of the beacon as defined in a configuration file which has been transmitted to it (by an OP_CONF module, as we will see later in connection with Figure 7) from the electronic control unit 1 of the CUB display unit. The configuration carried out by the module B_CONFIG determines the operation of the beacon in reaction mode R or in detection mode D and carries out the identification coupling by registering one or more beacon identifiers identifying respectively the coupled beacon or beacons. The B_DETECT module manages the entire operation of the tag during an exercise.

The input / output interface 203, more precisely referenced 203a, 203b in FIG. 4, is an input / output port comprising inputs / outputs 203a to which an on / off button PW _B of the beacon and a LED diode _B forming power-on indicator and inputs / outputs 203b which are used for the control of the power supply unit 24.

According to a preferred embodiment, it will be noted that the electronic circuit 2 can be contained in a sealed manner in the body of the tag.

In general, the data communications in the cognitive training system according to the invention, between the server MS and the display unit or units CUB, are made by means of packets or PQ data messages whose general configuration is shown in Figure 5.

As shown in Figure 5, the general frame of a PQ packet includes a TI packet indicator, a PI packet identifier, a EA address, a DE recipient address, a DATA message field and a CRC cyclic redundancy.

The PQ packets transmitted are of different types and correspond to a session configuration mode or a session execution mode. In each of these two modes, the PQ packet can be an information message sending packet or an information message acknowledgment packet. The TI packet indicator makes it possible to differentiate between them the different PQ packets. The PI packet identifier is intended for the identification of duplicates in received packets.

In this embodiment, SYNC synchronization data can be encapsulated in the DATA message field. SYNC synchronization data allows the server MS to manage a synchronized sequence of common sessions executed on several CUB display units. This SYNC synchronization data is inserted into the PQ packet by the MS server and / or OP_SYN_RES synchronization software modules (as shown in Figure 6 by way of example) installed in the CUB display units, and are processed by them. Typically, the SYNC synchronization data includes a common clock supplied by the server MS to the CUB display units and fix the start times of the expected common events which must be synchronized in the CUB display units. During a common session, the server MS is informed by the visualization units CUB of the progress of the session in each of them and is therefore able to fix the starting times of common events.

With reference to FIG. 6, a nonlimiting example of an operating program OP_EXP of the display unit CUB, more precisely implemented by the control unit 10 of the electronic control unit 1 of said display unit CUB, is now described below. Such an operating program OP_EXP essentially comprises a software module OP_SES, a software module OP_CONF, a software module OP_RESUL and a software module OP_SYN_RES.

The OP_SES module is the kernel module which controls the execution of different cognitive training sessions which have been programmed and defined in an F_SES session file. The F_SES file is processed by an ITP interpreter module which retrieves different instructions and interpreted data relating to the configuration and execution of the sessions for the different participants J, among, in Figure 6, the participants Jl, Jn, ..., J4, around the same CUB display unit. Such a file F_SES makes it possible in particular to define the content or contents which will be displayed successively on one of the screens E of the display unit CUB, or even associated sounds. It also makes it possible to configure a predetermined display order, as well as a display time for each content, or even a pause or erase time for content that is also predetermined. The invention further provides an operating mode in which the ITP module reads the F_SES file randomly, so that two consecutive sequences of interpretation of said F_SES file by said ITP module instruct the same participant J differently via the screen or screens. E which have been allocated to it. The ITP interpreter module thus configures the software modules OP_CONF, OP_RESUL and OP_SYN_RES from the instructions and data extracted from the file F_SES.

For each of the participants, the OP_SES kernel module calls on the OP_CONF module to perform, from the interpreted data extracted from the F_SES file, the configuration of the CUB display unit and R, D tags. For this, the OP_CONF module performs the configuration steps AT_E, AT_R / D and CP_R / D and other possible configuration tasks that would be necessary for a specific application.

The steps AT_E and AT_R / D correspond respectively to the allocation of one or two screens E and to the allocation of tags R, D, to the participant J considered. The participants are then informed of these assignments by means of the CUB display unit, by a display on the screen or by voice message.

Step CP_R / D corresponds to the identification coupling between the reaction tag R and the assigned detection tag (s) D. To carry out this identification coupling, the identifier of each tag D to be coupled is communicated to the corresponding tag R through the data communication link L _R.

Once the OP_CONF module has completed its configuration, the process returns to the kernel module

OP_SES, at the level of a conditional step SP1 awaiting instruction. The reception at step SP1 (output Y) of a start instruction ST validates the start of a sequence of exercises EX among possibly a plurality of exercises EXi to EX _F.

Prior to the launch of the execution of an EX exercise, the process transmits a request for authorization to execute RS, or synchronization request, to the synchronization management module OP_SYNC_RES. The module OP_SYN_RES performs scheduling, monitoring and session synchronization functions in particular when a common session takes place with participants J who are assigned to different CUB viewing units, located in different places and connected through in particular the IP network and MP server. The RS request allows the OP_SYNC_RES module, on the one hand, to stay informed about the progress of the exercise sequence and, on the other hand, to master it. Information deduced from RS requests is integrated into the synchronization data SYN of the packets PQ, for a transmission to the server MP which is responsible for the general synchronization of the cognitive training system. Execution of exercise EX is launched when an authorization S_EN is received by the module OP_SES from the module OP_SYNC_RES.

The OP_RESUL module manages the EX exercise. The module OP_RESUL performs in particular mental chronometry measurements CHRO and makes a decision of success / failure S / E on the performance of exercise EX by participant J. Event data ED (t), representative of the motor responses, are transmitted by the R, D tags, and are used for CHRO measurements and the S / E decision. The ED (t) data specify the occurrence over time of the events detected by the tags R, D. The success or failure of the exercise EX can be determined by comparing measured durations DM between the occurrences of the tag events at maximum durations granted for the financial year. The I / O decision is communicated to the OP_SES module for its management of the EX exercises. The CHRO measurements and the S / E decision obtained in an exercise EX _n are used by the module OP_RESUL to adjust a difficulty of exercise DIF for the exercise following EX _{n +} i. The DIF difficulty can be adjusted by means of the maximum durations granted for the exercise and / or a more or less significant exercise complexity. The DIF difficulty adjusted by the OP_RESUL module is transmitted to the OP_SES module for application to EX exercises. The different results and data ED (t), CHRO, S / E, DIF obtained by the module OP_RESUL are used for the formatting of a history of HIST session as the EX exercises progress. At the end of the session, the HIST history is transmitted to the server MS for integration thereof into a general history of participant J.

The end of the sequence of exercises EXi to EX _F , represented by the block F_SE, is indicated by the signal F_EX on the module OP_SYNC_RES. The DISP block represents the display of the results of the session on one or more E screens. This display can be subject to an S_DISP authorization from the OP_SYNC_RES module, for example, for a simultaneous restitution of these results to several participants J to a common session cognitive training.

Figure 7 shows another example of deployment of a cognitive sports training system comprising two sets of interconnected objects according to the invention.

The sets of interconnected objects here comprise two display units CUB _A and CUB _{b to} which several tags R1A, D1A, R2A, D2A and R2B, D2B are attached, respectively.

In this configuration example, two participants J1A and J2A use the display unit CUB _A and tags R1A, D1A and R2A, D2A, in a similar manner to participants J1 and J2 in the example in Figure 1. The tags R1A , D1A and R2A, D2A are analogous to the tags RI, DI and R2, D2 in Figure 1. The tags R1A, D1A and R2A are interconnected to the display unit CUB _A through data communication links L _R i _A , L _D i _A and L _R2A which are analogous to the links L _R i, L _D i and L _R2 of Figure 1.

The CUB _b display unit is located in a location which is far from the location of the CUB _a display unit. The display units CUB _A and CUB _b are in communication with the server MS via data communication links L _S ca and L _S cb, respectively, in a manner analogous to the display unit CUB in FIG.

1.

A J2B participant uses the CUB _b display unit and R2B, D2B tags, which are analogous to the R2A, D2B tags, of the J2A participant. The R2B tag is a reaction tag and the D2B tag is a detection tag comprising a passive RFID tag. The detection beacon R2B is connected to the display unit CUB _b through a data communication link L _R 2b similar to the link Lr2A ·

In this example, participant J1A alone performs a cognitive training session. The J2A and J2B participants are, for example, members of the same group and participate in a common cognitive training session. The same exercises are offered to participants J2A and J2B. The launch of the joint session of J2A and J2B participants must be synchronized and also, possibly, the launch of different sequences of exercises included in the joint session. Similarly, feedback of results to participants J2A, J2A, will also be synchronized.

A PH smartphone is used here by the trainer to control the launch and running of cognitive training sessions. The PH smartphone has a dedicated application for this purpose.

PH smartphone is connected to the display unit through a _CUB L _S data communication link Tila link L _S ti is typically a Bluetooth connection type as described above. The PH smartphone is also in communication with the MS server, connected to the IP internet network, through a data communication link L _S t2 · The L _S t2 link is established through a cellular telephone network authorizing data exchanges such as GRPS, 3G or 4G networks.

Through his PH smartphone, the trainer has access to all of the pre-programmed sessions and can start their execution once they have been downloaded to the CUB _A , CUB _b display units. In general, preprogrammed sessions can be stored in the viewing units CUB _A , CUB _b , in the server MS and, of course, in the dedicated application installed in the smartphone PH. The trainer can also create new sessions with his 5 smartphone and order their download in the viewing units CUB _A , CUB _b , for their execution.

Of course, the invention is not limited to the particular embodiments which have been described here by way of example. Those skilled in the art, depending on the applications of the invention, will make different modifications and suitable variants.
