Abstract: To solve the poor reliability of subjective selection and the lack of comprehensive quantitative research of objective selection in product shape schemes,a selection model based on multiple eye movement data was proposed.RED desktop eye tracker and BeGaze software were used to collect the eye movement data of 30 professional subjects for evaluating 4 different automobile shape schemes,and the subjective evaluation was obtained with subjective scoring table.Through one-way analysis of variance,the eye movement data concerning subjective rating was selected and modeled with simple Partial Least-Squares regression (PLS1).The mathematical model between multiple eye movement data and subjective rating was established and analyzed.Research results showed that the comprehensive analysis result of multiple eye movement data could reflect subjects' evaluation on shape schemes,which was able to provide objective support for product shape scheme selection.
