Eye-tracking, one of the various methods for the estimation of spatial images, makes it possible to analyze the observation characteristics while people are receiving the images through the observation by their eye movement. However, while it can make us obtain precise and objective observation data, it has the aspect that the method of analyzing the observation characteristics has not been established yet. Accordingly, I, for this study, analyzed the characteristics of each observation section and those of observation scope according to the grading of observation values and the partitioning of observation images respectively so that I could establish the partitioning standard to divide the scopes for the observation analysis. 1) I, analyzing the average value and deviation value of the observation data, studied the degree of dispersion by partition type through analyzing the average value and the deviation value of observation data to find out that the partitioning them into small sections could reflect the characteristics of the subjects' observation values more clearly. 2) In case of partitioning them into small sections, when those observation data happening mainly to design elements are partitioned into areas, they can be divided to be different with one another, and so partitioning the scope too minutely can cause the dispersion of the concentration scope. 3) The analysis of the observation characteristics by observation-grading section led me to find out that Type 4 was the optimum where the frequency at Section I with the lowest observation frequency was less than 50% and that at Section V is more than 3%. 4) The Partition Type 4 has the observation image partitioned by 12 x 12, and the one partitioned scope is rectangular and its size is 1.9 times of central fovea's area. But given that the central fovea is circular, its radius is 1.05 - 1.4 times of central fovea. Considering the partitioning type and the central fovea's size, it can be concluded that the scope a little bigger than the size of central fovea should be the standard for the size of observation scope.
