Method for evaluating time of individual's response to moving object

FIELD: medicine.

SUBSTANCE: person being tested is presented with a circle, which comprises a mark and a point object, on a monitor screen. The point object moves at a preset speed around the circumference; at the moment the moving point object and the mark are supposed to converge, the individual presses the Stop button to stop the circular motion of the moving point object. After a preset time, the motion of the point object is reactivated. The described procedure is repeated for the preset number of times; after stopping the circular motion of the point object, a deflection of the point object from the mark is evaluated. The time of the individual's response Tr to the moving object is evaluated as an arithmetic mean value by formula

wherein ti is the i-th deflection of the point object from the mark, ms; n is the number of stops of the point object in the area of the mark.

EFFECT: method enables providing the more reliable evaluation of the time of the individual's response to the moving object ensured by the fact that the time of delay or advance error is accepted as deflections of the stopped moving object from the mark and taken with a positive sign.

sabreena relates to medicine, and is intended to assess the reaction time of a person on a moving object.

One method of improving the reliability and efficiency of professional activity of the person is the diagnosis and prediction of its functional state. A simple and reasonably accurate physiological indicator of the functional state is a reaction to a moving object [1].

There is a method of evaluating the response time of a person on a moving object by bringing the subject on the screen of the video monitor of a circle, which contains a label and a point object, characterized in that a point object moving with a constant speed on a circle, in the time of the alleged coincidence of the position of a moving point object tagged with the subject by pressing the "Stop" stops the movement of a point object on a circle, then calculate the mismatch error of a point object and label - error time delay with a positive sign or lead with a negative sign, and after a time delay to resume motion of a point object on a circle described procedure is repeated specified number of times, then calculate the estimate of the reaction time Tpman on a moving object as the value according to the formula:

,

where ti/sub> i I the following error with a positive sign or lead with a negative sign, MS; n is the number of stops of a point object in the field of TIC [2].

The disadvantage of this method is not reliable estimate of the reaction time on a moving object.

The closest to the technical nature of the proposed method is a method of estimating the response time of a person on a moving object by bringing the subject on the screen of the video monitor of a circle, which contains a label and a point object, characterized in that a point object moving with a constant speed on a circle, in the time of the alleged coincidence of the position of a moving point object tagged with the subject by pressing the "Stop" stops the movement of a point object on a circle, then calculate the error does not match the bitmap object and label - error time delay with a positive sign or lead with a negative sign, and after a time delay to resume motion of a point object on a circle described procedure is repeated specified number of times, and then compute the estimate of the reaction time Tpman on a moving object as an average value according to the formula

where tii I the following error with a positive sign or lead with tricatel the major sign MS; n is the number of stops of a point object in the field of TIC [3].

The disadvantage of this method is not reliable estimate of the reaction time on a moving object.

Evaluation of the reaction time on a moving object is calculated as the sum of the errors lag is positive and proactive with a negative sign, or as an average value of these errors, it is not possible to estimate it reliably. Path when testing the response time to a moving object two subjects received the following error values do not match the provisions of point object and marks:

- for the first Respondent+10, -10, +10, -10, +10, -10, +10, -10, +10, -10 MS shown in Fig.1;

for the second Respondent+5, -5, +5, -5, +5, -5, +5, -5, +5, -5 MS shown in Fig.2.

The sum of the errors lag is positive and proactive with a negative sign, and the average of the values of these errors both subjects are the same and equal to zero. But the equality to zero of the sum of errors and their arithmetical mean values does not indicate any value of the reaction time on the moving object. At the same time, the error values do not match the provisions of point object and marks the second Respondent is less than the first, therefore, his reaction time on the moving object smaller.

The technical result of the proposed method estimates the time R the action of a person on a moving object is to improve the reliability of the estimates.

The technical result is achieved by the fact that the subject present on the screen of the video monitor circumference, which contains a label and a point object, the bitmap object is moving with a constant speed on a circle, in the time of the alleged coincidence of the position of a moving point object tagged with the subject by pressing the "Stop" stops the movement of a point object in a circle, after a time delay to resume motion of a point object described procedure is repeated specified number of times, and the new is that after stopping the motion of a point object on a circle calculate the deviation of the point object from the label, the evaluation of the reaction time Tpman on a moving object is calculated as an average value according to the formula

where ti- i-e is the deviation of the point object from the mark, MS; n is the number of stops of a point object in the field position of the label.

In Fig.1-2 presents the diagram of the error values of the lag and lead of the two subjects.

In Fig.3 presents a circle, placed the subject on the screen of the video monitor, where 1 - marker, 2 - point object moving with a constant speed in a circle.

In Fig.4-5 presents the diagram of the error values of the lag and lead of the two subjects.

Th is method a method of estimating the response time of a person on a moving object is carried out as follows.

The subject present on the screen of the video monitor circumference, on which is placed a label 1 and a point object 2 moving with constant speed on a circle (Fig.3). The subject, watching the movement of the point object 2, in the time of the alleged coincidence of the position of a moving point object 2 with label 1 press the "Stop" button stops the motion of the point object 2 on the circle. Then calculate the deviation of the point object 2 from the mark 1 and after a time delay to resume motion of a point object 2 on the circle.

The person performs the described procedure specified number of times, and then calculate the response time Tpman on a moving object according to the formula (2).

Thus, the inventive method estimates the response time of a person on a moving object has new properties, conditional on receiving a positive effect.

Example 1.

The subject P., age 19, on the video monitor screen of the personal computer brought the circle, which contains the label 1, on a circle clockwise moves with a given speed of a point object 2, making one revolution in 2 (Fig.3).

The subject, watching the movement of the point object 2 on the circle, in the time of the alleged coincidence of the position of the point object 2 with the position of the label 1 pressed key of the keyboard of a PC is a "Gap" the function of Stop button. The computer at the time you press the Spacebar stopped the movement of a point object 2 on the circle, calculate the error does not match the point object 2, and labels 1 - error time delay with a positive sign or lead with a negative sign, determined the deviation of the point object 2 from the mark 1, put the calculated value of the mismatch error and bias in the storage device and 1 with continued movement of the point object 2 on the circle.

Tested in accordance with the recommendations [4] performed 13 stops the motion of a point object 2 in the position of the label 1, the first three of which in the evaluation of the reaction time on the moving object was not taken into account. As the result, obtained the following values of mismatch error of the point object 2 and the label 1 in MS: 14, -6, 25, -14, 8, 30, 14, -16, 14, -13, which is shown in Fig.4, and the variance of the point object 2 from the label 1 in MS: 14, 6, 25, 14, 8, 30, 14, 16, 14, 13.

Evaluation of the time response of the person on the moving object calculated by the formula (1), 5.6 MS, according to the formula (2) with 15.4 MS. Obtained values of the estimated reaction time differ 2.75 times.

Example 2.

The subject that is, 20 years, similar to the subject P., completed the test in the evaluation of the reaction time on the moving object. As the result, we obtained the following values of the Oia error mismatch provisions of point object and labels in MS: -22, 6, -27, 19, -28, 11, -23, 22, -26, 17, which is shown in Fig.5, and the variance of the point object 2 from the label 1 in MS: 22, 6, 27, 19, 28, 11, 23, 22, 26, 17.

Evaluation of the time response of the person on the moving object calculated by the formula (1), is equal to minus 5.1 MS, according to the formula (2) is 20.1 MS. Obtained values of the estimated reaction time vary 3.94 times.

The positive effect of the proposed method estimates the response time of a person on a moving object is confirmed by the results of experimental research on group of 10 subjects. Values estimated response time calculated by the formulas (1) and (2) differ in the studied group from 1.9 to 5.3 times.

Thus, the proposed method allows a more reliable estimate of the reaction time on a moving object.

SUBSTANCE: circle on the monitor screen is presented to the subject, on which a mark and a point object is placed. The point object moves at a predetermined speed along the circle. The testee stops the movement of the point object along the circle at the time of the proposed coincidence of its position with the mark by pressing the "Stop" button. Then the mismatch error of the point object and the mark is calculated. This is the time of trailing error with a positive sign or anticipation with a negative sign. After the predetermined time, the motion of the point object along the circle is resumed. The described procedure is performed the specified number of times. The order statistics of mismatch errors of the point object and marks is created. The range of the order is calculated by the formula: R=tmax-tmin. The ratio of the largest member of the order statistics tmax to the range R is calculated, multiplied by 100. The maximum absolute value of the prediction error |tpred.max| is determined. The lower quartile (25% quantile) of the maximum absolute value of the prediction error |tpred.max| is calculated. The percentage P of the absolute values of the prediction errors is determined, which are in the lower quartile of the maximum absolute value of the error |tpred.max|. Rating P is calculated as the reciprocal number of the arithmetic mean of the range R, the ratio of the largest member of the order statistics tmax to the range R, multiplied by 100, and the percentage Per of the absolute values of prediction errors which are in the lower quartile of the maximum absolute value of the prediction error |tpred.max|, multiplied by 100, according to the formula: P=100×1/(R+100×tmax/R+Per)/3=300/(R+100tmax/R+Per). The testee who has a higher rating is regarded as the most promising and able to show better results in upcoming competitions.

At the first stage of training it is necessary to achieve body adaptation to the impact of quasiantipodal stimulating signals, at the second stage it is necessary to obtain conditional reflex for one out of stimulating signals, for this purpose one should accompany this stimulating signal with discomfort impact, during the third stage, finally, due to volitional efforts one should suppress body reaction to stimulating signal. The devise suggested contains successively connected a transformer of physiological parameter into electric signal and a bioamplifier, an analysis and control block with a connected block to present the signals of biological feedback, a block for presenting discomfort impact, an indication block and that of forming and presenting quasiantipodal stimulating signals. The innovation enables to have skills to control one's emotions, decrease sensitivity threshold to environmental impacts and learn to how behave during stress situations.

EFFECT: higher efficiency of training.

SUBSTANCE: method involves measuring patient weight, recording age and sex of the patient. The patient is positioned in front of computer display unit. The data are inputted into the computer comprising software containing a program for estimating organism organs and systems condition. The following organs are detected. Lung, spleen, heart, kidneys, liver are proved for having deviations from norm with negative sign towards hypofunction or with positive sign towards hyperfunction. The data are displayed with the program on the screen as a table with reference and current values being shown in relative units with plus or minus sign. Canal states are estimated from detected organs being under maximum stress on the basis of infogram: lung canal P, spleen - canal RP, heart - canal C, kidneys - canal R, liver - canal F. When estimating organ state with deviation having plus sign, that means hyperfunction, canal state is estimated as having energy excess. When organ state deviation has plus sign, that means hyperfunction, canal state is estimated as having lack of energy. Eye diseases are diagnosed from state of organs and canals of P, RP, C, R and F. Hyperfunction in organ and excess in canal being available, initial ophthalmic disease stage is diagnosed. Hypofunction in organ and deficit in canal being available, chronic ophthalmic disease stage is diagnosed.

EFFECT: wide range of functional applications.

SUBSTANCE: method involves carrying out situation, planning, self-control and correction analysis. Volitional effort is included into functional self-organization process structure components. Functional self-organization process structure components characterize the following individual human specific characteristics: 1) goal-setting as taking and retaining aims; 2) situation analysis as revealing and analyzing circumstances essential from the point of view of achieving the set goal; 3) planning as scheduling private activity; 4) volitional effort as changing private activity sense; 5) self-control as controlling and estimating private actions; 6) correction as adjusting private goals, situation analysis, plan of actions, private activity sense, estimation criteria and self-control forms. Human self-organization process structure diagnosis is set after relaxation training aimed at relieving emotional effort and overfatigue. The relaxation training is exercised in coachman position with calming musical accompaniment and comprises the following stages: 1) respiratory exercises (inspiration duration is equal to expiration one, breath is hold between the inspiration and expiration for a time twice as short as inspiration time) 4 min long; 2) relaxation exercises (invoking heaviness and warmth sensation) of head, arms, legs and body -8 min long; 3) rest in maximum relaxation state - 4 min long.

EFFECT: high accuracy of diagnosis.

SUBSTANCE: method involves showing sequence of two luminous pulses of 10 ms duration separated by 150 ms long pause. The pulses are repeated in constant 1.5 s long interval. Pause duration between two luminous pulses is reduced at the first measurement stage at constant speed of 20ms/s until a testee fixes fusion of two luminous pulses into single one in subjective assessment mode. Pause duration between two luminous pulses is increased at the second measurement stage with given constant step of 0.4 ms until the testee identifies the moment of subjective perception of two luminous pulses separation. Pause duration is reduced in discrete mode with given constant 0.1 ms long step at the third measurement stage until the testee identifies the moment of subjective perception of two luminous pulses fusion into single one. Human vision system persistence time is determined to be equal to pause duration between two luminous pulses when subjective fusion into single pulse takes place at the third measurement stage.

EFFECT: high accuracy in determining human vision system persistence time.
