The utility model relates to biometry, in particular, to devices for recording the physiological parameters of individuals under emotional influence on them, mainly when watching video information (film, commercial, etc.), when reading audio materials, reading text or listening to questions from a researcher . The system can be used in conducting sociological, socio-psychological and marketing research to obtain information about changes in the physiological parameters of respondents in response to changes in their psycho-emotional state, which, in turn, changes under the influence of the information presented, which is the subject of these studies.

A device is known for determining changes in the emotional state by a speech signal (see USSR author's certificate No. 793575, IPC АВВ 10/00).

However, this device is not applicable for recording the response to the presented media information, as while watching (listening) you should observe silence (be silent).

However, this device is not applicable to the field of research, the subject of which is media information.

Known electronic devices intended for stationary research or occasional use in the form of portable devices in which the vegetative indicators of the electrocardiogram (ECG), heart rate (HR), respiratory rate (BH), etc. are recorded (monitored). One such device is Diagnostic portable instrument “Mir”, which allows to simultaneously register heart rate and BH in humans using special sensors (Diagnostic instrument “Mir”. Operating Instructions. Ros Tov-on-Don. Center for Scientific and Technical Creativity of Youth, 1990, 25 p).

Known devices such as a polygraph for measuring physiological parameters in assessing emotional and stressful tension - human skin resistance and / or heart rate in response to a verbal stimulus, for example, to test questions (see RF patents for invention No. 2068653, IPC АВВ 5/16; 2317774, IPC А61В 5/16).

One of such devices for the analysis of psychophysiological information contains a block of sensors designed to measure various physiological parameters, such as BH, blood pressure, galvanic skin reaction (RGR), etc. The outputs of the sensor unit are connected to the corresponding inputs of a multi-channel analog-to-digital converter.

The biometric device is a user pulse wave registration device. A feedback biometric system is a variant of a lie and / or stress detector. Feedback is determined by the impact on the subject, for example, using a monitor on which text information or another image appears that changes the emotional, physiological and psychological state of the subject (user), which leads to a change in the volume pulse recorded by the system using DactoChip. A fingerprint scanner converts the pulse wave in each element of the DactoChip into a digital signal transmitted to a personal computer. The biometric system analyzes the simultaneous change in the user's state depending on the effect exerted on him and can draw a conclusion about the physiological and / or psychological state of the user, for example, as a lie or stress detector (see RF patent for the invention No. 2199943, IPC АВВ 5/02 )

This device allows you to assess the condition of one subject, but does not allow you to evaluate the "average" response of a group of respondents (target audience), which is very important for obtaining reliable data in case studies.

However, this device is complex, extremely expensive, difficult to apply in conditions of group studies, requires qualified personnel to carry out such studies, and poses a known danger to respondents due to the presence of super-powerful electromagnetic fields, etc.

The objective of this solution is to create a device that allows you to record the response of the target audience (focus groups of respondents) to the impact of media information.

The technical result - the objectification and increase the reliability of sociological, socio-psychological and marketing research while simplifying the device and minimizing the harmful effects on respondents.

The problem is solved by taking from the respondents their physiological parameters during the conduct of these studies and recording changes in these parameters as a response to the presented media information that is the subject of the study (film, commercial, audio, text, researcher's questions, etc.). For this, the system for recording the response of the target audience to the impact of media information contains n personal modules, each of which contains physiological parameters sensors connected to a unit for collecting and transmitting data from personal modules, which is connected by a communication channel to a central unit for receiving, recording, storing and processing data configured to track the presence, magnitude and moment of changes in the physiological parameters of individuals of the target audience that occurred under the influence of the media information, where n is the number of individuals of the target audience.

The central unit for receiving, registering, storing and processing data can be implemented either as a combination of a computer and a separate device connected to this computer, while the device receives data from personal modules via wired or wireless communication and ensures the transfer of these data to a computer, or implemented in the form of only a computer using standard computer tools for receiving and transmitting data via wired (USB, COM, FireWire, LAN, etc.) or wireless (Bluetooth, WiFi, etc.) communications.

The utility model consists of the following main components: blocks for taking data from respondents - personal modules, and a central unit for receiving, registering, storing and processing data, which includes a computer with software installed on it designed to register, store and process received data trends (time dependencies) of physiological parameters of respondents.

Pulse sensor 1 (Fig. 1) is connected through an amplification, filtering and signal limiting unit with amplitude 2 to one of the inputs of the ADC 9, which is part of the microcontroller 8. The measurement electrodes of EX-3 are connected to a protection circuit from static potentials, the output of which is connected to the inputs two amplifiers 5 and 6 working in parallel. The outputs of the amplifiers through the filters 7 are connected to two other inputs of the ADC 9 of the microcontroller 8. The output of the microcontroller 8 is connected to the input of the data transmission module via a radio channel with a built-in antenna 10. The personal module has an autonomous power supply unit consisting of a charger connector 11, a battery charging circuit 12 , the battery 13 itself, the power switch 14 and the voltage regulator 15, which feeds the remaining elements of the system.

Blocks 2, 4-15 form a block 23 for collecting data from sensors 1, 3 and transmitting them to a central unit for receiving, registering, storing and processing data.

The pulse sensor 1, structurally combined with one of the electrodes for measuring the EX 3, as well as the second electrode for measuring the 3 EX have fastening means on the fingers of the respondents also with straps with Velcro fasteners.

The central unit for receiving, registering, storing and processing data consists of a central module for receiving data, which is connected to the unit for recording, storing and processing data, which is a computer with software installed on it that allows you to register, save and process data received from personal modules and track the presence, magnitude and moments of changes in the physiological parameters of individuals that have occurred under the influence of media information being the subject of research , which allows us to draw a conclusion about the degree of emotional involvement of individuals in relation to the provided media information, to identify individual moments in the flow of this media information that have had the greatest impact on individuals, and to evaluate the overall effect on individuals of all media information in general.

The central data receiving module (Fig. 2) is a device connected to a computer via a USB port. It contains a series-connected module for receiving data via a radio channel with a built-in antenna 16, a microcontroller 17, a microcircuit 18 for matching the microcontroller 17 with a standard USB interface, and a USB connector 20 for connecting the device to a computer. The microcircuit 18 has a built-in voltage driver 19, from which power is supplied to both the microcircuit 18 itself and the remaining blocks of the circuit. LED 21, connected to the microcontroller 17, serves to indicate the receipt of data from personal modules.

The system operates as follows. Personal modules are connected to each individual and measure one or more physiological parameters of the individual related to his emotional state (pulse rate, respiration rate, electro-skin resistance, galvanic skin reaction, blood pressure, etc.). They are designed to measure and transfer physiological parameters of respondents to the central unit of registration, storage and processing of data taken from respondents at the time of research. In a specific implementation of the personal module, the measurement of two independent physiological parameters of the respondent is provided: the pulse rate and the magnitude of the responder's electro-skin resistance. In this embodiment, personal modules are placed on the hand of each respondent from the selected focus group (Fig. 3). Further, respondents are invited to familiarize themselves with the material that is the subject of the study, in particular, to watch a new feature film. At the time of viewing the material presented, data on the physiological parameters of respondents are taken by the system and transferred to a computer with software installed on it, designed to register, store and process this data.

The personal module (figure 1) works as follows.

The signal from the pulse sensor 1, based on the photoplethysmographic method and placed on the respondent’s finger, is fed to the amplification, filtering and signal limiting unit by amplitude 2, where it is amplified, filtered by frequency and, if necessary, limited by amplitude. Further, the pulse signal is fed to one of the inputs of the ADC 9 of the microcontroller 8, where it is converted into a digital code. The program of the microcontroller 8 extracts the main harmonic from the pulse signal and measures its period, thereby measuring the heart rate.

The signal from the electrodes of EX-3 placed on two different fingers of the respondent’s hand goes to the protection circuit from static potentials 4, which protects the high-impedance inputs of amplifiers 5 and 6 from random static potentials that are possible when the respondent first touches the electrodes 3. Next, the EX signal is separated and simultaneously arrives at amplifiers 5 and 6. Amplifier 5 has a unity gain (voltage) and is intended only to provide a high input impedance to the measurement circuit for the signal from the electrodes measurement of EX-3. Amplifier 6 has a voltage gain of 3, and is designed to provide a high input resistance of the measurement circuit for the signal from the electrodes of the EX-measurement, as well as to amplify the signal from the measurement electrodes of the EX-3 with relatively small values of the respondents' resistance and provide more high resolution measurements of these relatively small values. The signals from the outputs of amplifiers 5 and 6 pass through frequency filters 7, removing high-frequency noise from the signals, and are fed to the other two inputs of the ADC 9 of the microcontroller 8, where they are converted into a digital code. The microcontroller program can choose between a single-gain EX signal and an 3-times amplified EX signal. So, with the respondent's EX from 0 to 350 kOhm, a signal with a gain of 3 times is selected, which provides a higher resolution for measuring the EX. When the respondent's EXC is more than 350 kOhm, an EX signal with a single gain is selected, which, with a relative decrease in resolution, provides a wider range of measurement of the EX. The results of the measurement of the pulse rate and the responder's EX, as well as a special serial number, individual for each personal module, are transmitted to the data transmission module 10, from where they are transmitted via radio communication to the central data receiving module (Fig. 2).

The entire device is powered from the battery 13 through the power switch 14 and the power supply voltage stabilization unit 15. Power from the voltage stabilizer 15 is distributed to each element of the device circuit (the power connections in Fig. 1 are conventionally shown as several arrows extending from the power stabilizer 15).

When the battery is discharged below a critical level, the voltage regulator 15 informs the microcontroller 8 of the low charge of the power battery, and the microcontroller transmits relevant information to the central data receiving module. Ultimately, this information will be presented to the system operator on a computer screen for timely charging of the battery of this personal module. The battery is charged by periodically connecting the personal module through connector 11 to the charger (not shown in the diagram). In this case, the energy from the charger through the charging circuit 12 replenishes the battery 13.

The Central module for receiving data (figure 2) is designed to receive data from one or many personal modules and transfer them to a computer and works as follows.

Data from the personal modules via radio is transmitted to the data receiving module 16, after which, through the microcontroller 17 and the microcircuit 18 matching the microcontroller 17 with the standard USB interface, as well as the USB connector 20 are sent to the computer (the computer is not shown in the diagram).

The microcircuit 18 has a built-in voltage driver 19, which, due to the energy supplied through the USB connector 20 from the computer, feeds both the microcircuit 18 itself and the rest of the device circuit.

The microcontroller 17 is necessary for coordinating the interfaces of the data receiving module 16 and the microcircuit of the USB interface 18, for the initial configuration of the data receiving module 16 and for controlling the LED 21. The LED 21 is necessary to indicate the flow of data transmitted from one or many personal modules.

Based on the presence, magnitude and time of the onset of changes in the physiological parameters of the respondents, a conclusion is drawn on the degree of emotional involvement of the respondents in relation to the information provided, certain moments in the flow of media information that have the greatest impact on the respondents are identified, and the overall impact on the respondents of all the presented media information in whole. The system can be used to record the response to the impact of media information for each individual from the target audience individually and to all individuals from the target audience combined when conducting sociological, socio-psychological and marketing research.
