Description

The invention relates to the field of psychology and psychophysiology and can be used in legal proceedings, in the selection of personnel, conducting screening inspections and corporate investigations.

The problem of determining the falsity of transmitted information is one of the most relevant for many areas of human activity (politics, economics, legal practice, forensics). However, despite the constant need to establish objective truth, at the moment there are no reliable methods for instrumental diagnostics of the reliability of information transmitted by humans. Non-instrumental diagnostic methods are not always reliable due to the subjective factor - the assessment of the dynamics by a human psychologist.

The closest analogue of the developed device can be recognized (RU, patent 2337607, publ. 10.11.2008) a device used in the implementation of the method for assessing the psychophysical state of a person. The known device consists of an electronic unit, a video camera recording the angular displacement of the eye in the orbit, the patient’s head holder and video camera, a fluorescent lamp providing uniform illumination of the eye, a personal computer connected via an analog-to-digital converter to the video camera output. For image input, the Matrox Marvell G400 video capture card is used, which supports full-format input of video materials at a speed of 30 frames per second, and the software supplied with it for capturing video images in an AVI format file.

A disadvantage of the known device should be recognized as the patient’s unnatural position at the time the information was taken, which leads to a distortion of the patient’s non-verbal behavior, as well as the lack of consideration of the majority of the patient’s non-verbal actions, since only eye movement is taken into account.

The technical problem solved by the developed device is to expand the range of devices used in the field of psychology and psychophysiology.

The technical result obtained by the implementation of the developed device consists in increasing the reliability of the research results by increasing the number of measured parameters, as well as eliminating subjectivity in their analysis.

To achieve the specified technical result, it is proposed to use the developed diagnostic device for the falsity of the reported information on the dynamics of the parameters of non-verbal human behavior. The developed device comprises at least a first video camera installed with the possibility of removing video information from the patient’s face, a second video camera installed with the ability to remove video information from the patient’s feet, a third video camera installed with the ability to remove video information from the patient’s body, a highly sensitive microphone installed near the patient’s mouth, as well as the electronic unit, to which are connected via blocks of significant differences of the video camera and a highly sensitive microphone, and at least Here, cameras are connected to blocks of significant differences, just like blocks of significant differences are connected to the electronic block via wires, while the electronic block is capable of analyzing the information received from the blocks of significant differences with making a judgment on the falsity of the information communicated.

The term “device”, according to publicly available literature published by the Russian Academy of Sciences (see “Explanatory Dictionary of the Russian Language” / edited by S.I. Ozhigov and N.Yu. Shvedova / (any edition)) means (with respect to technology) technical construction , mechanism, car, device.

In the Civil Code of the Russian Federation (Chapter IV), on the basis of which the patentability of technical solutions is determined, the legislator has not defined what should be understood by the term device.

However, in the publicly available source of information (RD 03-247-98 "Regulation on the registration, registration and registration of permits for the manufacture and use of technical devices in the Gosgortekhnadzor system of Russia"), related to the field of regulatory literature, the legislator defined the device as "... technological equipment, units , technical systems (complexes), equipment, devices, their units and components ... ”.

The developed diagnostic device for the falsity of reported information on the dynamics of non-verbal behavior of a person contains at least a first video camera installed with the ability to remove video information from the patient’s face, a second video camera installed with the ability to remove video information from the patient’s feet, a third video camera installed with the possibility of removal video information from the patient’s body, a highly sensitive microphone installed near the patient’s mouth, and the video cameras are connected to an electric Nome unit over a significant difference blocks by means of wires (electric cables), the electronic control unit is arranged to analyze information received from the significant difference blocks from the judging falsity notification information.

Thus, the developed device contains at least three material circuits of structural elements (a video camera - a block of significant differences - an electronic block) connected by wires (electric cables), through which an information signal is transmitted, which is, as is well known, an electric signal.

A highly sensitive microphone can also be connected to the block of significant differences and through the specified block with the electronic block wires with the formation of the fourth chain. But the connection can also be formed by the radio channel, while a chain of interconnected structural elements is also formed.

The parameters of non-verbal behavior of the patient can be used the frequency of lip licking, the frequency of swallowing saliva, the frequency of blinking, the number of deep breaths, the number of smiles, the number of movements of the facial muscles in the forehead and eyebrows, the narrowing-expansion of the nostrils, the number of movements of the lips, head, shoulders, body, the number of gestures - illustrations, the number of gestures - manipulations, the number of movements with brushes and fingers, the number of movements of the legs and feet, the frequency of the change of pose. Most of these parameters are controlled using cameras, and the rest using a microphone.

The developed device contains at least four channels for collecting information from the patient during a dialogue (conversation), three of which contain video cameras, each connected through its own block of significant differences to the electronic unit, the fourth channel contains a highly sensitive microphone installed near the patient’s mouth, connected through its block of significant differences to the electronic block. These channels make it possible to record non-verbal information using video cameras from such parts of the patient’s body as the face, legs and body, and using a highly sensitive microphone allows breathing and swallowing of saliva, which allows the block of significant differences to reveal the dynamics of the parameters of non-verbal behavior of the patient. In the presence of a television lens, large-scale optical information is received from the patient at the input of the camera, which allows you to change the smallest changes in the parameters of non-verbal behavior of the patient. In some embodiments of the developed device, it may further comprise a fourth video camera installed to enable the removal of video information from the eye area and connected through a block of significant differences to the electronic unit.

In a preferred embodiment of the developed device, a chair for the patient is installed in the room intended for conversation (interrogation) with the patient, the cameras are hidden in the interior or in the walls of the room so that the field of view of the first video camera covers the patient's face, the field of view of the second video camera the patient’s body, preferably its upper part with the shoulder girdle region, the field of view of the third video camera is the patient’s legs, preferably the foot region. The fourth video camera, if used, is focused on the eye area.

A highly sensitive microphone can be connected via a block of significant differences to the electronic unit via wires.

Before starting the conversation, the patient is seated in a chair, warned of the need to record the conversation on a tape recorder and put a hoop on the patient’s head with a tape recorder, preferably configured to register the patient’s breathing and swallow saliva. The second microphone is dressed by a psychologist conducting a conversation. It is through this microphone that the conversation is recorded.

As a block of significant differences, a device known from RU, 133642 can be used, which makes it possible to trace the dynamics of changes in the parameters of nonverbal patient behavior according to an algorithm specified in the device, or the like.

During the conversation, initially establishes psychological contact with the patient, asking insignificant questions, the answers to which do not change the psychological state of the patient. These may be questions about the weather, about the patient’s well-being, about his living conditions, etc. At the same time, non-verbal information is received from video cameras and a microphone with a simultaneous analysis of the received information by blocks of significant differences and an additional analysis carried out by the electronic unit based on data received by the indicated electronic unit from the blocks of significant differences. Then, having received a signal from the electronic unit about establishing ranges of non-verbal parameters when the patient reports true answers, the psychologist asks two or three questions to which the patient must give deliberately false answers. Since the psychologist carefully familiarizes himself with the biography of the patient, as well as his psychological portrait, before the interview, the psychologist always chooses questions that must be answered either false or at least unbalancing the patient’s behavior. Then the psychologist asks in an arbitrary sequence questions that cause or do not cause a change in the non-verbal parameters of the patient’s behavior. Also, the psychologist can instead of making statements make statements based on the psychological portrait of the patient, obviously causing a negative or enthusiastic reaction of the patient.

Moreover, in a preferred embodiment of the use of the developed device, the obtained video and audio information is recorded, as well as the results of its analysis on an independent medium connected in an electronic unit, which allows further analysis of the patient’s behavior.

The information received and analyzed by the electronic unit on the state of the dynamics of the parameters of non-verbal behavior of the patient allows us to conclude that the patient is able to regulate his non-verbal behavior. If the patient is in full control of his non-verbal behavior, then the conversation should be discontinued due to its meaninglessness. If the electronic unit reveals the dynamics of changes in the parameters of non-verbal behavior of a person when giving false answers, then the psychologist continues the conversation, asking substantive questions, while the developed device provides an assessment of the falsity of patient responses.

The presence of at least four independent data acquisition channels, each of which contains a device for processing the received information in the form of a block of significant differences, eliminates the possibility of skipping changes in at least one of the parameters of non-verbal patient behavior.

Since the evaluation is performed by an electronic device, a subjective approach to assessing the sincerity or deceit of answers is practically excluded.
