Abstract:
1. A method of evaluating tactile sensations of a car seat cover, comprising: identifying a type of the car seat cover; obtaining values for one or more physical characteristic factors of the car seat cover in accordance with the identified type of the car seat cover; quantitatively evaluating a first set of tactile sensations with regard to the type of the car seat cover, including determining quantitative numerical values of the first set of tactile sensations based on the one or more physical characteristic factors including mechanical and thermal/physiological characteristic factors input to a statistical recursive model for the evaluation of a corresponding tactile sensation of the first set; grading the mechanical and thermal/physiological characteristic factors and the determined quantitative numerical values of the first set of tactile sensations, yielding a first set of grade values; quantitatively evaluating a second set of tactile sensations with regard to the type of the car seat cover, including setting the quantitative numerical values of the first set of tactile sensations as input values, subjecting the set input values to an artificial neural network model for the evaluation of a corresponding tactile sensation of the second set, and determining quantitative numerical values of the second set of tactile sensations; grading the determined quantitative numerical values of the second set of tactile sensations, yielding a second set of grade values being within a predetermined range; and displaying the first and second sets of grade values, wherein the identified type of car seat cover comprises a leather type, and wherein the values for the mechanical and thermal/physiological characteristic factor values comprise values for at least one of the group consisting of: S(Softness), μ(sliding resistance coefficient), RB(bending resilience (%)), RT(tensile resilience (%)), P(moisture vapor permeability(mg/cm
