METHOD OF INCREASING ACCURACY OF ESTIMATING TIME OF PERSON'S REACTION AT MOVING OBJECT Russian patent published in 2012 - IPC A61B5/16 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and medical equipment and is intended for increasing accuracy of estimation of time of person's reaction at moving object. A circumference on which a mark and a point object moving with specified speed on circumference are placed is shown to the tested person on videomonitor screen. At the moment of supposed match of position of the moving point object with the mark the tested person stops movement of the point object on the circumference by pressing "stop" button. Error of mismatch of the point object and mark is calculated, time of delay error with the positive sign or forestalling error with the negative sign, and after specified time movement of the point object on the circumference is resumed. Time of error of the point object and mark mismatch is marked on the plane in coordinates "error of mismatch - number of the point object stop". Described procedure is repeated several times, diagram of values of mismatch errors t is built as of function t=f(N_i), where N_i is the number of i-th stop of the point object in region of the mark location, l=1,2,…, k, k is the quantity of stops of the point object in region of the mark position, before obtaining quasistationary mode, when transitive process is over. In quasistationary mode specified number of stops of the point object in region of the mark position is made after which assessment of time of person's reaction at moving object T_p is calculated by formula: where t_j is value of mismatch error in j-th stop of the point object in region of the mark position, ms; j= k,k+1,…, k+(n-1); k is number of stop of the point object in region of the mark position, corresponding to the end of transitive process (beginning of quasistationary mode); n is quantity of stops of the point object in region of the mark position in quasistationary mode.

EFFECT: method makes it possible to increase accuracy and reliability of assessment of time of person's MOR by statistic processing of its values obtained in quasistationary mode.
