To improve the practical application value of the traditional one-dimensional variable KE model, the method of constructing multi-dimensional variable kansei engineering (MVKE) model was proposed.Firstly,the space of multi-dimensional modeling features (MMFs) and emotion perception were set up.Next,the main features were determined and parameterized.Then,the mapping function relationship between the space of MMFs and kansei design was analyzed and the MVKE model based on the form,color,sound,material and related components of product was constructed by multiple regression analysis method.Finally,the method of the model construction and the performance evaluation of the model were described by a case of numerical control machine tools form design.The performance of the MVKE model was evaluated by validation experiment and comparative experiment.The validation experiment was used to evaluate the practicability of the model by comparing the values of the prediction and user survey.The comparative experiment was used to evaluate the accuracy between the one-dimensional variable KE model and the MVKE model by judging their goodness of fit.Experimental results revealed that the MVKE model has more excellent performance.It is more according with people's cognitive style,therefore it can aid emotional design effectively.
