- GB 2 221 759 also discloses a method for physiological evaluation of the response of a human subject to advertising messages, using recordings of electroencephalograms. It is a question of measuring in real time the variations of cerebral activity of this human subject. This process requires specific medical equipment which makes it difficult to implement for audience measurements which must be carried out at the same time at the home of a large number of panelists.
- biometric information of a physical, biological or physiological nature intended to undergo statistical processing.
- the aim of the invention is to propose a system for collecting and processing biometric information transmitted by human subjects in response to a communication message, a system for which the subject's response is minimally disturbed by the conditions of acquisition and collection of said information, in order to avoid distorting the results of the analysis of this response.
- One way to do this is to place the processing device at a distance from the subjects and the devices for acquiring and collecting information.
- biometric information processing implies that a large number of subjects receive the communication message, preferably simultaneously.
- These subjects can be very distant from each other. They can be isolated or gathered locally in groups of subjects. Means of transmission of the information collected at the level of each subject facilitate their processing in a single central site.
- the system comprises: - for each human subject, a personal acquisition and transmission device comprising:
- a specific application of the system according to the invention consists in extracting from the analysis of the subjects' responses to the perceived communication messages parameters that quantify the effects of these messages on the target audience.
- the central reception, processing and analysis means are arranged to provide an evaluation of the intensity of the emotional shock of the message perceived by each human subject equipped with a personal device. acquisition.
- the system further comprises, at the level of human subjects, interactive means for questioning these human subjects and for receiving their responses, and means for transmitting these responses to the central site of processing, to provide an assessment of the consistency of the message.
- the invention also relates to a method implemented by the system for the evaluation of a communication message, comprising the following steps:
- a message is sent to the subject via a visual and / or audio medium, (for example a television set or a radio broadcast station, ...) - the response is measured biometric from subject to message using personal acquisition devices,
- said method comprises an additional step during which an evaluation is made of the intensity of the emotional shock of the message perceived by each human subject equipped with a personal acquisition device.
- the method according to the invention can also include the following three additional and successive steps:
- questions are sent to the subject via a visual and / or audio medium
- the method comprises an additional step which consists in the course of which an evaluation is made of the degree of consistency of said message. So that the collection of biological and / or physiological information disturbs the subject as little as possible, it preferably uses non-invasive means of acquisition. Also the personal acquisition device comprises means arranged to measure information available on the surface of the subject's body, such as in particular neuro ⁇ muscular excitability, a difference in heart rate, or a variation in temperature.
- the subject does not modify his natural and spontaneous behavior when receiving the message, because of discomfort caused by the presence of the personal acquisition device.
- the personal acquisition device is preferably designed to occupy a reduced bulk.
- it is included in a current and discreet accessory of everyday life, that the subject carries with him. Thus the subject can manage to forget his presence.
- a wristwatch that the subject wears on one of his wrists as mentioned in the cited prior art, or in a bracelet that the subject wears on one of his ankles or in a spectacle frame, or even in a time strip.
- the accessories likely to receive the personal treatment device are not limited to those which have just been listed.
- the information acquired at the level of each subject is sent to the central site for processing and analysis.
- a first step in this routing is done locally, from the personal acquisition device to a local collection device, located near the subject or group of subjects perceiving the message.
- the personal acquisition device for this purpose comprises means for instantaneously processing information of a physical, biological or physiological nature emitted by the subject in response to the message, and converting them into signals, and means for instantly transmitting these signals to the local device.
- the local collection device comprises conventional means for receiving said signals.
- the second stage of routing is the transmission of the signals received by the local collection device to the central processing site.
- the local collection device is arranged to instantly transmit said information to the central processing site.
- the local collection system is organized to store the information it receives, and transmit it offline to the central processing and analysis site.
- the storage criteria can, depending on the case, be based on the number of information received or on a determined time interval.
- the local collection device includes both means for instant communication of information, and for storage of these for their subsequent communication to the central site.
- This interactive management system for information broadcast on television media includes: - a plurality of local sites equipped with a television receiver set up to receive information from local or remote information media, a local collection device and interactive management system cooperating with the television receiver and provided for: (i) controlling a selective display of locally or remotely generated request messages, (n) collecting response information sent by a user in response to said request messages by means of a portable input device cooperating with the local device for interactive collection and management, and in a central management and processing site, means for remotely controlling the local device for interactive collection and management and means to collect the response information collected by the local collection system and interactive management.
- This interactive management system is characterized in that each local device for interactive collection and management is arranged to manage the interactions of a plurality of users with television programs broadcast on this television set, and to associate with each reception of a response to a request an identification of the program corresponding to this request and an identification of the user sending this response.
- These local collection and interactive management systems have the following functions: essential, on the one hand, to control the display, on the screen of a television set, of grids, images, sequences, or animations intended to elicit interactions, and on the other hand, to receive and process information and decisions issued by the viewer using his multi-function or specific remote control.

- the most efficient current measurement systems simultaneously implement two technologies: a black box type management device and a remote control: the management unit identifies the selected channel while that the remote control allows the panelist to indicate that he is watching a program.
- Management box technology is reliable and should continue to experience improvements over time, particularly with the inclusion of the channel code name in the broadcast signal.
- the reliability of the indication by remote control is much more questionable because it rests on the will of the panelist to follow the procedures. Because of this human factor, the reliability of current processes can hardly exceed 50 to 70%.
- the interactive management system according to the invention offers both greater flexibility of use, in particular allowing multiple users to be taken into account in the same room and better reliability than current interactive systems.
- the portable input devices can be either specific and dedicated to the local device for interactive collection and management, or associated with remote control devices of the television receiver.
- each local device for interactive collection and management is arranged to receive in addition, from users of said system, signals representative of emotional shocks felt by these users in response to the broadcasting of a program on television equipment, these signals received being also associated with an identification of both the program concerned and the user transmitter of these signals.
- the portable capture devices are preferably associated with physiological signal sensor devices representative of emotional shocks felt by users.
- a personal portable device comprising means for picking up physiological signals emitted by the wearer, means for entering responses to requests, and means for transmitting these physiological signals and these responses to the local device for collecting and managing interactive.
- This personal portable device is preferably of the bracelet type and can perform a watch function.
- a method for interactively managing information broadcast on televisual media comprising:
- this method further comprises local management of the interactions of a plurality of users with television programs broadcast on this television set, and, on each reception of a response to a request, an identification of the program with which this request is associated and an identification of the user sending this response.

- a biometric nature for example neuromuscular excitability , difference in heart rate and thermal variation.
- Neuromuscular tension constitutes the most reactive modification of the above-mentioned variations.
- a variation of this neuromuscular tension precisely quantifies the force of the impact or emotional shock and can be measured by a biometric technique or "biofeedback".
- biometric technique biofeedback
- biofeedback signals which provide a voltage proportional to the stress of the wearer, via an acquisition and amplification chain
- the emotional shock data measured by the system according to the invention and represented on a scale of 1 to 10 are obtained from a correlation law between the "biofeedback" signals and the movement signals of the wearer. These two types of data are sampled every 1/100 of a second on a wristwatch according to the invention.
- biofeedback signals (B) are picked up, amplified and then sampled with voltage levels on the order of a millivolt the microcontroller (8 bits) of the wristwatch.
- the value resulting from this processing is between 0 and 255.
- the motion signals (M) are directly acquired and sampled at voltage levels of the order of a millivolt and converted into a resulting digital quantity between 0 and 255.

- This particular application is interesting for advertisers who wish to test their advertising messages, for film production companies for their trailers, and for the organizers of symposia, conferences and conventions in order to know the reaction of spectators and participants.
- it is possible to design a system comprising: a set of 250 acquisition and transmission wristwatches 1,
- a local interactive collection and management device 304 and a collection and processing station 307 arranged in the control room 301.
- the removable technical modules of the wristwatches are reinforced in terms of radio transmission / reception: they must be more precise in reception and more powerful in transmission than the removable modules used in a room of a dwelling.
- Each participant 311 is identifiable by the wristwatch 1 which he wears and which constantly measures the emotional impact which he undergoes during the conference or presentation.
- the participant 311 wearing a wristwatch 1 according to the invention responds to the programmed questionnaires by pressing the buttons arranged on the technical module of his watch.
- the emotional impact scores and the answers to the questions are immediately recorded by the local collection and interactive management device 304 and then transmitted to the collection and processing station 307 for processing.
- Such an auditorium efficiency measurement system also has the advantage of being easily transportable.
- the information that can be collected from participants can be many and varied.
- the further processing of the information collected by the psychostrategy method can also allow the clients of the system to optimize their messages. We can thus envisage a new realization of a film, modifications in an advertisement, or a reorganization of the speech of a speaker.
- the system and method according to the invention can also be used as a working tool in focus or reflection groups ("Focus Groups"), in particular in communication agencies. It is then a question of measuring the effectiveness of any communication message with a view to their optimization. These efficiency measurements are carried out in real time, on a representative development group of around 20 people, in terms of understanding, evaluation and buy-in, emotional impact and degree of consistency.
- This particular application of the collection and processing system according to the invention can relate to any type of communication, for example corporate communication, advertising, promotion, direct marketing, all types of product communication (for example, packaging, design, merchandising), any type of interpersonal communication (for example, manager, distributor, sales force) and any type of internal communication in a company.
- the present invention can also be of interest to financial analysis, by making it possible, for example, to collect the reactions of financial actors directly to fluctuations in the stock markets, in particular in order to be able to anticipate the reactions of these markets.
