Description

The field of technology to which the invention belongs

The present invention relates to the psychology and psychophysiology of labor and is intended for the operational measurement of the level of performance of workers in hazardous activities using artificial intelligence. Operational measurement of the level of performance allows to reduce the risk of injuries and accidents.

State of the art

Currently, a significant number of methods, techniques and devices for measuring the level of performance have been developed, which, with high reliability and validity, do not differ in sufficient efficiency.

Working capacity (of a person) is understood as a characteristic of the available or potential capabilities of an individual to perform expedient activities at a given level of efficiency for a certain time. Efficiency depends on individual psychophysiological resources, the degree of their training or exhaustion, as well as external conditions of activity. In relation to the problem being solved, maximum, optimal and reduced performance are distinguished (Big psychological dictionary: ACT; AST-Moscow; Prime-Eurosign; Moscow; St. Petersburg; 2008. ISBN 978-5-17-055694-6, 978-5-17- 055693-9; 978-5-9713-9307-8; 978-5-9713-9308-5; 978-5-93878-662-2; 978-5-93878-663-9).

Those skilled in the art have proposed various methods for measuring performance levels. The following are the best known and closest to the present invention.

The known method of "Landolt's Ring" is a method designed to assess the overall performance of a person and its components: productivity, speed, accuracy (error-free), endurance and reliability (Workshop on psychology. Edited by A.N. Leontiev, Yu.B. Gippenreiter. - M.: Publishing House of Moscow State University, 1972. - 95 p.). The test is carried out using a special form, common for all tests, with rows of rings with gaps. The subject looks through the rings on the form row by row and crosses out the rings with a certain gap. Every 2 minutes, on command, the subject must mark with a vertical line how many rings he has already viewed. Five tests are carried out without interruption. The results of the test are evaluated by the number of missed not crossed out rings and by the number of viewed rings in each of the five samples. Accordingly, testing lasts 10 minutes. There are also modified computer versions of the method (for example, SU 1346132 A1, 1987.10.23. RU 2686247 C1, 2019.04.24.).

Methods of express diagnostics of working capacity and functional state of a person M.P. Frost (www.imaton.com). The technique is intended for diagnosing the functional state of the central nervous system (CNS) of a person and predicting its performance based on the indicators of variational chronoreflexometry - the dynamic characteristics of the time of a simple visual-motor reaction. It is implemented in the form of a computer program that allows you to fully automate the entire process of collecting, processing and storing diagnostic data. The entire testing procedure takes 5 minutes and can be carried out repeatedly, since it does not cause a training effect. The technique can be effectively used in industry, energy, transport, armed forces, medicine, sports and education (patent RU 2164075, published 03/20/2001).

A known method for diagnosing the functional state of a person, which is as follows. The subject is presented simultaneously with 4 digits from 0 to 9. The presentation time is set in the range of 0.5-1 s and the time interval after which the presentation is repeated is in the range of 1 to 5 s. Moreover, the specified parameters are constant throughout the experiment. Then, the number of counted presentations to the subjects of this figure is compared with the actual number of presentations, and the working capacity is determined by the magnitude of the error (patent RU 2136211, published 10.09.1999).

The disadvantage of the above methods and their computer versions is the need to involve a highly qualified specialist and the need to equip a separate workplace for functional diagnostics at the enterprise itself, as well as the need to analyze and evaluate the results by a highly qualified specialist increases the total testing time (from the start of testing to obtaining results).

There are also complex hardware methods, including methods for assessing the level of performance, in particular the following.

The UPDC-MK Auto Professional complex of Neurocom JSC (www.neurocom.ru) is designed to solve problems of traffic safety in transport. Allows you to objectively assess the personal characteristics of a person. Testing should be carried out by a psychologist trained at NEUROCOM JSC. The UPDK-MK complex has different options for completing with methodological and technical means.

The hardware-software psychodiagnostic complex Multipsychometr (www.multipsychometr.ru) allows for a comprehensive assessment of the level of development of a wide range of professionally important qualities, psychological and psychophysiological properties, characteristics of the psychological state of candidates based on the results of their performance of psychodiagnostic methods or their combinations.

This is a unified system of psychophysiological tests aimed at assessing: the “Central nervous system”, “Functional state” and “Non-specific performance” of a human worker before admitting him to the workplace, to potentially hazardous areas or types of work. The purpose of the complex is to prevent, prevent through the fault of the "human factor" the possibility of "emergency situations", unauthorized and erroneous human actions. The result of the application of the complex is the final conclusion with the wording: "admission or non-admission". The complex serves 1-2 specialist psychologists or psychophysiologists. At the same time, any number of employees can be surveyed (the number of personal computers connected to a local network, corresponding to the number of surveyed (per shift), is required).

Hardware-software complex for testing and developing the psychological and psycho-physiological qualities of vehicle drivers "Meleti" with the function of issuing an automatic conclusion without the participation of a professional psychologist (professional version), designed for psychological and psycho-physiological testing of professional drivers in motor transport enterprises (https://www.autopolis .ga/catalog/apk_testirovanija_i_razvitija_psihofizicheskih_kachestv_voditela_393/apk_meleti_professionalnaja_versija_2987.htm1), Complex "ROFES" (Dyatlov, M. N. Devices for the psychophysiological examination of drivers. M. N. Dyatlov. Young scientist. - 2013. - No. 4 (51). 59-61 - URL: https://moluch.ru/archive/51/6579/). The hardware-software complex (professional version) provides for several types of psychological and psycho-physiological testing: psychological and psycho-physiological testing when applying for a job, consisting of 22 tests; periodic psychological and psychophysiological testing of the driver in order to assess the dynamics of the professionally important qualities of the driver, consisting of 13 tests (it is recommended to conduct 2 times a year, as well as after the use of special exercises); pre-trip check of the functional state of the driver, consisting of 4 tests - must be carried out before leaving the line. In addition to the test results, the complex provides recommendations and a description of special exercises with which the driver can improve or compensate for low performance. At the same time, any number of employees can be surveyed (the number of personal computers and hardware and software systems corresponding to the number of surveyed (per shift) is required.

The disadvantages of using the above complexes for the purpose of quickly measuring the level of performance are:

- lack of an integral assessment of various performance indicators;

- overload with diagnostic methods;

- the need to attract a highly qualified specialist and / or a separate room;

- large time costs for data analysis and preparation of a conclusion on the level of performance according to individual methods.

The closest analogue of this solution is the Hardware-software complex of pre-shift psychophysiological control "Control - Admission" (Certificate of state registration of the computer program No. 2015617642 for the invention "Automated psychophysiological control "control-admission" (APK "KD")" dated 07/16/2015) , but it requires an appropriate amount of hardware and an equipped room for localized testing of employees, as well as the involvement of highly qualified specialists for the evaluation procedure.

The main performance indicators are attention, speed and accuracy of the reaction, which in diagnostic practice are evaluated independently of each other. Doctor of Biological Sciences, Senior Researcher of the Scientific Research Testing Center for Biomedical Protection M.P. Moroz showed that in order to determine the functional state (working capacity), it is not necessary to make complexes from a variety of methods, but it is enough to apply variational chronoreflexometry (https://psy.su/feed/2219/) and take into account indicators of attention. However, from the point of view of considering attention as a cognitive-integral process, when assessing performance, it is necessary to take into account indicators of attention, speed and accuracy of reaction, in their totality, since their assessment separately is not sufficiently informative to conclude about the level of performance. For example, with a diagnosed low level of attention and a high reaction rate, the risk of erroneous actions increases (a person does not have time to identify a stimulus in order to respond to it in a timely manner, and makes a mistake in identifying a stimulus or responds in a timely manner at random). With a high level of attention and a low reaction rate, the risk of a delayed reaction increases (a person does not have time to respond to a stimulus in a timely manner) (Vorontsova Yu. Instrumental study of attention in non-equilibrium mental states (on the material of professional drivers) // Scientific notes of the Crimean Federal University V.I. Vernadsky Sociology Pedagogy Psychology 2019 Volume 5(71) No 3 P.84-93

These regularities indicate the need for an integral assessment of performance based on a set of indicators of attention, speed and accuracy of reaction, expressed in an integral index of performance, taking into account the different weight of the measured indicators in their relationship.

Despite the availability of reliable and valid methods for measuring the performance level of their computerized versions and devices, there has not yet been developed a methodology for an integral performance assessment that allows for prompt short-term diagnostics, which can be carried out remotely for the purpose of pre-shift control, or during a shift.

Disclosure of the Invention The present invention describes a method for an integral assessment of the performance of a test subject, which includes assessing the concentration of attention by passing the test subject at least a variation of the Landolt test, assessing the activation of the central nervous system (CNS) by passing the test test a simple visual-motor reaction and assessing the level of sensorimotor reactions by passing the test of a complex visual-motor reaction, the determination of the integral assessment of the performance of the subject according to the formula:

где

Implementation of the invention

The present invention includes several main steps of the method for determining the level of performance of the subject, in particular: the identification of the subject, the message of at least one message associated with the stimulus material; demonstration of at least one kind of stimulus material; fixing at least one response of the subject; checking the correctness of at least one answer of the subject; fixing the time spent by the subject on at least one answer, and / or the time from the beginning of one test to the last answer of the subject to this test; determining the performance level of the subject based on the time spent by the subject on at least one answer, and the correctness of at least one answer of the subject; determination by the formula of the integral assessment of working capacity; determining the level of performance of the subject on the basis of an individual cumulative database of indicators of attention, speed and accuracy of the reaction.

In the present invention, artificial intelligence is used to analyze the physiognomic profile. In a preferred, but non-limiting embodiment, artificial neural networks are used.

In a broad sense, a neural network is a parallel network consisting of simple processors or "neurons" that have the ability to accumulate empirical knowledge. Knowledge is acquired through learning, not programming, and is stored in the interconnections between neurons in the network. For such a machine system, the relative importance of the features is not important, since the neural network perceives all the features provided, and decides for itself which features are significant, insignificant, or redundant. At the beginning of learning, all features essentially have the same significance, as learning progresses, the machine itself decides on the level of significance of each feature. In general, the more people and features used for training, the higher the accuracy of subsequent results when using a neural network to evaluate people who have not previously been tested.

The artificial intelligence applied to feature analysis may include an artificial neural network, a genetic algorithm, a decision tree, fuzzy logic, symbolic rules, machine learning, and other kinds of intelligence. The entrance to the PSY FACE application is carried out on a technical device (smartphone, tablet).

In FIG. 1 shows a flowchart showing the process of the method for the integral assessment of the testee's performance, which includes several stages: identification of the testee, conducting the first, second and third tests. As the first test, a variation of the "Landolt Ring" test is used, as the second test - a test of a simple visual-motor reaction, as a third test - a test of a complex visual-motor reaction.

In FIG. 2 is a flow chart showing the process and results of the tests used in the present method. A variation of the "Landolt Rings" test allows you to determine the assessment of attention concentration, the test of a simple visual-motor reaction - an assessment of the activation of the central nervous system, and the test of a complex visual-motor reaction - an assessment of the level of sensorimotor reactions.

After entering the application (Fig. 3 shows a screenshot from the application), windows appear for entering personal data (last name, first name, patronymic, date of birth) and selecting the name of the employer's company. Below is the Continue button. This button is activated after entering data in all the proposed windows.

After pressing the "Continue" button, a window opens with a view of the image from the front camera for verifying and fixing physiognomic features during testing and the "Take a photo" button.

After pressing the "Take Photo" button, the photo and two buttons are displayed on the screen: "Retake" or "Done". If you select the "Reshoot" button, the previous step is repeated. In one of the embodiments, the photo can be processed and used as an identifier, for example, similar algorithms are used in FacelD technologies (for example, on cell phones).

If the “Finish” button is pressed, the “Start” button appears, pressing which launches the testing algorithm (an adapted version for presenting on a mobile technical device (smartphone, tablet) the Landolt Ring method; “Simple visual-motor reaction”, “Complex visual- motor reaction", "Complex visual-motor reaction with a choice of three alternatives"). The algorithm for presenting tests involves their variation.

Example:

After pressing the "Start" button, under a large heading, the Instructions for a variant of the "Landolt Ring" technique adapted for presentation on a mobile technical device (smartphone, tablet) are opened. The text of the instruction (Fig. 4): “The screen will display a set of rings with a gap in one of eight directions: at 13 (15, 17, 18, 19, 21, 23 and 24) hours, if you focus on the clock face.

An example set of rings is shown in FIG. 10.

It is necessary to sequentially view the lines from left to right, without missing a single one, and select rings with a break for 15 hours by single touching the screen (the name of the ring break changes randomly in the instructions with each next test). After touching, the ring will be highlighted in blue (highlighted darker than the others).

An image corresponding to the example is shown in Fig. eleven.

The test lasts 260 seconds. Every 52 seconds, a sound command “Dash” is given (a visual signal can also be given, as shown in Fig. 5), according to which it is necessary to mark the last viewed ring (even if it is incorrect) with a single touch of the screen and, without stopping, continue working further . A line will appear in place of the marked ring.

An image corresponding to the example is shown in Fig. 12.

As you progress through the test, already viewed rings are darkened.

After 260 seconds, the “Dash” command is given, after which it is necessary to mark the last viewed ring with a single touch of the screen (even if it is incorrect). It is necessary to work as quickly as possible, but at the same time accurately.

If you touched the ring incorrectly, press it again and the selection will be cancelled.

Upon completion of the test, instructions for the next test will appear on the screen.

After reading the text of the instruction, the subject presses the "Continue" button and the test begins.

The first stage of the test is designed to assess the subject's correct understanding of the instructions.

A short instruction is presented on the screen:

INSTRUCTIONS

Click on the correct ring

An image is shown, for example, as in FIG. 13.

Below is the Start Test button. The button is activated only after selecting the correct ring.

After pressing the "Start test" button, an image is displayed on the screen, which is a modified optotype of Landolt rings in the form of rings with rounded edges at the break. The features of the rounding of the rings and their filling - "noise", are due to the need to form the effect of monotony. In some embodiments, implementation of the present invention, at least part of the ring is filled with noise, in some embodiments completely (which includes the expression "at least a part"). The sequence of breaks presented in the test rings is given in random order with the condition that there is no repetition of more than three identical breaks. The test lasts 260 seconds, and each of the five trials takes 52 seconds. Testing times may vary. The time of the test is reduced in contrast to the original test due to the fact that the purpose of the study is to identify the concentration of attention. The generation of a sequence of rings with gaps is carried out by means of a random number generator or a pseudo random number generator, i.e. with each new test, the subject will be asked to choose rings with a gap in a certain place (the first factor of uncertainty) and the sequence of rings itself will differ (the second factor of uncertainty). The use of a random order (or pseudo-random order) allows you to completely eliminate the effect of addiction and provides a guarantee of the purity of the test.

The results are processed in one of the embodiments of the invention according to the Methodological Guide “Landolt Test. Health diagnostics”, V.N. Sysoev, which reveals ways to determine the average productivity, average accuracy, reliability and other indicators. The present invention takes into account the following indicators: average productivity (Pt), average accuracy (At), reliability. Then an integral assessment of performance is determined, namely the concentration of attention, using the formula:

где

Where

Value Amp - level of reliability indicator;

Value At - average accuracy level;

ValuePt - level of productivity indicator;

Upon completion of the version of the Landolt Ring method adapted for presentation on a mobile technical device (smartphone, tablet), instructions for the next test - "Simple visual-motor reaction" are displayed on the device screen.

Instructions: “Red shapes will appear on your screen. Click on the red shape as quickly as possible when it appears. The shape of the stimulus (circle, square, triangle, rhombus, others are possible) changes randomly during subsequent testing. In some embodiments, the shape of the stimulus may change during testing.

It is allowed to change and change the location of the stimulus in one test. The optimal number of stimuli for the test is 33. The number of stimuli is not strictly specified. The optimal stimulus exposure time is 1 second. The exposure time of the stimulus is not strictly specified and may vary randomly. The optimal time interval between the demonstration of stimuli is from 0.5 to 3 seconds. The time interval between the demonstration of stimuli is not strictly specified and can vary randomly in order to exclude the formation of the effect of waiting for the appearance of a stimulus with a certain time interval (responding within a given time interval).

The following indicators are taken into account: average reaction time, standard deviation (ms), number of correct reactions, number of erroneous reactions, number of measurements during one test. Erroneous reactions can be of two types: 1) omission of a stimulus (lack of response (touching a figure on the screen of a mobile technical device) to the presentation of a significant stimulus); 2) premature actions (touching the screen of a mobile technical device during the refractory™ period without understanding the action).

An integral assessment of CNS activation is determined according to the Methodological Guidelines for organizing and conducting psychophysiological examinations of personnel of energy enterprises. RD 153-34.0-03.504-00 (Approved by RAO UES of Russia on May 12, 2000, by the Ministry of Health of the Russian Federation on June 19, 2000).

Upon completion of the "Simple visual-motor reaction" test, instructions for the next test - "Complex visual-motor reaction" are displayed on the device screen.

Instructions: “Red and green figures will appear on your screen. Tap the shapes as quickly as possible when they appear, the red shape with a single tap, the green shape with a double tap. In some embodiments of the present invention, other color combinations may be used.

It is allowed to change the stimulus (circle, square, triangle, rhombus, others are possible) and its location in one test. An embodiment is shown in FIG. 6 and FIG. 7. The optimal number of stimuli is 63. The number of stimuli is not strictly specified. Stimuli are presented in random order, and there must be the same number of two stimuli that differ in color and/or shape. The reaction speed is determined for the first stimulus at the moment of touching the screen, for the second stimulus (described in the instructions as a green figure) at the moment of the second touch of the screen. The optimal stimulus exposure time is 1 second. The exposure time of the stimulus is not strictly specified and may vary randomly. The optimal time interval between the demonstration of stimuli is from 0.5 to 3x seconds. The time interval between the demonstration of stimuli is not strictly specified and may vary randomly. The number of stimuli in the preferred embodiment of the invention should be minimal and sufficient: minimal to reduce testing time, but sufficient to obtain reliable results.

The following indicators are taken into account: average reaction time, standard deviation (ms), number of correct reactions (reactions to a significant signal correspond to the instructions for the task), number of erroneous reactions, number of measurements. Erroneous reactions can be of three types: omissions of the stimulus (lack of response (touching the figure on the screen of a mobile technical device) to the presentation of a significant stimulus), false reactions (response (touching the figure on the screen of a mobile technical device) upon presentation of an insignificant signal), premature actions .

An integral assessment of the level of sensorimotor reactions is determined according to the Methodological Guidelines for organizing and conducting psychophysiological examinations of personnel of energy enterprises. RD 153-34.0-03.504-00 (Approved by RAO UES of Russia on May 12, 2000, by the Ministry of Health of the Russian Federation on June 19, 2000).

The test "Complex visual-motor reaction" provides for the possibility of replacing it with the test - "Complex visual-motor reaction with a choice of three alternatives".

Instructions: “Red and green figures will appear on your screen. Tap the shapes as quickly as possible when they appear, the red shape with a single tap, the green shape with a double tap. When the blue figure appears, do nothing.

It is allowed to change the stimulus (circle, square, triangle, rhombus, others are possible) and its location in one test. The optimal number of stimuli is 78. The number of stimuli is not strictly specified. Stimuli are presented in random order, and there must be the same number of two stimuli that differ in color and / or shape, to which it is necessary to respond. In some embodiments of the present invention, the test is conducted in noise mode. Interference can be of various types, in particular visual, auditory, tactile. As a non-limiting example, interference can be in the form of constant or episodic ripples in all or part of the screen of devices. In addition to ripples, distortion of the displayed area of the screen or part of the screen, jitter, which can also be constant or episodic, as well as other types of interference, can be applied. As examples of auditory interference, in particular, various sounds, messaging, transmission of interference sound (for example, as when searching for radio stations), broadcasting of radio stations, television broadcasts, etc. can be used. Vibration of a phone or tablet, vibration of a manipulator can be used as tactile interference (for example, a joystick, such as a mouse, keyboard, if they are equipped with feedback). All interference options can be used separately from each other, alternately, simultaneously, in combinations with each other. The reaction speed is determined for the first stimulus at the moment of touching the screen, for the second stimulus (described in the instructions as a green figure) at the moment of the second touch of the screen. The optimal stimulus exposure time is 1 second. The exposure time of the stimulus is not strictly specified and may vary randomly. The optimal time interval between the demonstration of stimuli is from 0.5 to 3 seconds. The time interval between the demonstration of stimuli is not strictly specified and may vary randomly.

The same indicators are taken into account as in the "Complex visual-motor reaction" test. An integral assessment of the level of sensorimotor reactions is determined according to the Methodological Guidelines for organizing and conducting psychophysiological examinations of personnel of energy enterprises. RD 153-34.0-03.504-00 (Approved by RAO UES of Russia on May 12, 2000, by the Ministry of Health of the Russian Federation on June 19, 2000).

Then the integral assessment of working capacity is determined using the formula:

где

Where

SR1P - integral assessment of CNS activation;

IntLandolt - integral assessment of attention concentration;

SR2P - integral assessment of the level of sensorimotor reactions.

Upon completion of the test, the “RESULT” button appears on the screen of the device. When it is pressed, the test result is displayed on the screen in the form of a gradient battery (Fig. 8), the colors of which vary depending on the success of the test. The battery and its gradient is a form of representation of the integral test score, reflecting the percentage of success in the tests. When you touch the battery, a verbal description of the test result is displayed on the device screen. The test results are presented in two forms: for the "User" and for the "Customer". Example for the User: “Attention indicators correspond to the norm. The speed and accuracy of the reaction correspond to the norm. An example for the Customer: “the speed of processing information about the sources of danger is normal, the ability to see the right decision is normal, the stability of attention while maintaining the speed and accuracy of information processing is normal, the reaction speed is within the normal range, the stability of the response to danger, the error-free actions are normal.” In particular, the test results for the Customer provide additional information: the number of tests for a certain period; the percentage of test results with satisfactory and unsatisfactory results ("risk group") for the specified time period (month, half year, year); individual profile of the level of performance for the specified time period (month, half year, year); the number and personification of users included in the risk group for the specified time period (month, half year, year).

In FIG. 9 is a screenshot from an application (application manual) showing the main steps and steps of the present invention.

A variation of the Landolt test according to the present invention in the preferred embodiment involves the demonstration on the screen of the device rows (rows) of rings. The optimal display is 8-11 rings in one row, the number of rows is limited by the vertical size of the screen. Rings have gaps in certain positions. The dimensions of the rings are given in relative units (for example, in pixels, or linear units, for example, millimeters): the diameter of the ring is 200 units, the thickness of the rings (the difference between the outer and inner radii) is 40 units, the distance between adjacent rings in the line is the same and in in some embodiments, equal to the distance between adjacent rows of rings. It is preferable to use a distance between lines and rings in lines equal to 4 or 5 units. The gap of the rings is 40 units wide, and the rings do not have "sharp corners", which are rounded with a radius of 20 units (i.e., a radius equal to half the thickness of the ring). The rings are at least partially flooded (colored) with noise, i. e. have arbitrary content, which is 50% of the full content (for example, if the number of pixels inside the ring is 40, then 20 pixels will be colored, the thickness of the rings will be 8 pixels, "sharp corners" will be rounded with a radius of 4 pixels). In some embodiments of the present invention, noise flooding is from 5 to 50%, in some embodiments, the intensity (density) of noise flooding can be from 50 to 95% inclusive. Each of the intensities is not specifically named in the description, but the specialist understands how to carry out such a fill. The presence of noise filling allows you to increase the monotony, i.e. make it difficult for the subject to recognize the rings by their shape (a similar disadvantage of the classical Landolt rings has been repeatedly described, for example, in patent RU 2695919), and requires attention when analyzing each ring.

The dimensions of the rings have been studied by specialists many times and various ring thicknesses, sizes of gaps in the rings, shape of the gaps have been proposed, but before the present invention, rounding of corners in the area of gaps and filling with noise were not used.

The present invention and all variants of its implementation are embodied by the authors in versions of the PSY FACE program, which confirms the industrial applicability of these solutions.
