A METHOD AND SYSTEM FOR QUANTITATING FATIGUE RESULTING FROM A THREE DIMENSIONAL DISPLAY

摘要

A method and a system for quantitating user's fatigue strength for a three-dimensional stereo image are provided to extract a parameter which causes fatigue of a user watching a three-dimensional stereo image or a two-dimensional image and quantitate the fatigue strength from the parameter. Words which represent fatigue according to a three-dimensional stereo image are selected from a plurality of words(S10). Factor analysis is performed on the selected words to divide the selected words into groups(S20). Words included in N groups having the highest factor weight among the groups are set as a subjective parameter(S30). An estimated score for the subjective parameter is inputted while a test value of an objective parameter candidate capable of numerically representing characteristic of the three-dimensional stereo image is varied(S40). The relationship between an index with respect to each of the N groups and the objective parameter candidate is obtained using the inputted estimated score(S50). The factor weight is applied to the index to represent final fatigue strength by the objective parameter candidate(S60).
