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 car seat cover, including determining quantitative numerical values of the first set of tactile sensations based on the obtained mechanical and thermal/physiological characteristic factors using a statistical recursive model; grading the mechanical and thermal/physiological characteristic factors and the quantitative numerical values of the first set of tactile sensations, yielding a first set of grades; quantitatively evaluating a second set of tactile sensations with regard to 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, and determining quantitative numerical values of the second set of tactile sensations; grading the quantitative numerical values of the second set of tactile sensations, yielding a second set of grades; and displaying the first and second sets of grades.
