The paper proposes a method to evaluate cooperative skills of individuals during machine operation. A formula to estimate the skill level was derived by investigating eye movements and performing statistical analyse of them. The analysis results in the training process of virtual vehicle operations confirmed that the velocity and distance of a saccade reflect well the cooperation skill with the correlation coefficients ranged from 0.48 to 0.76; hence, these characteristics were adopted as factors to estimate the cooperation skill level. These factors were used to conduct a principal component analysis and an outlier test to derive a canonical (not depending on individual differences) formula for skill estimation. The estimation accuracy was verified, and it was confirmed that the estimation model is effective when the correlation coefficient ranges from 0.56 to 0.84.
