Abstract. It is known that eyes moving tracks recorded by special design through equal time intervals while observing images have two basic appearances – saccades and fixations. Investigation’s aim was the development quantity fractal criteria of finding individual recognizable state of moving different observer’s eyes. The method of the fractal analysis consists in research of characteristics of same object at different scales. Criteria evaluation’s algorithm include sampling out of eyes trajectory saccades and fixation distinguished collect in adequate data sequence on X and Y operated separately. Every realization is operated through measuring window on z-steps data access in time sliding along realization by single step. On every step there were defined separately for realization saccades and fixation standard deviation σx on X and σy on Y and computed adequate σ(i) on full window size as σ(i)= where i=1:(N–z+1) – number shift’s step on realization length-N and j=1:z on full windows length. The measuring window’s size was changed as z=1:zmax. For every observer was performed data smoothing for images turn on with step-angle 45° (0°-315°). It was shown that smoothed by this operation values σmean(z) formed linear functional dependence у=a+bx with substantially different values of coefficients a and b for variety observers for saccades and fixations that provide individual observers.
