Abstract
A method and system of quantitatively evaluating subjective inconvenience, e.g., physiological fatigue and emotional fatigue, experienced by a user when the user views a three-dimensional display screen, based on objectively measurable indices. The method includes sorting words representing a degree of fatigue associated with a 3D image display among a plurality of words, grouping the sorted words through factor analysis, setting words with the highest factor weight as subjective parameters, receiving evaluation scores for the subjective parameters while varying test values of objective parameter candidates capable of representing 3D image characteristics in numerical values, obtaining a correlation between each of indices for N groups and each of the objective parameter candidates using the evaluation scores, and applying the factor weight to the indices to represent the degree of fatigue in the objective parameter candidates.
