Abstract
Applying the revised face method previouslyreported, it was studied that as follows;
i) The method was classified into groups of character based on human emotion; what is called‘joy, angry, sorrow and happy’.
ii) Relations among each group were explained by ‘catastrophe’ surface.
iii) And a degree of each face in the group was represented, and fixed by digital numerical value introducing the fazzy theory.
iv) It was shown that the method is being able to utilize the forecast of a phenomenon by applying ‘inverse problem of fazzy’.
In the concrete, a great number of data wereprocessed for the sole form of a foot and the exercise ability, and the above-mentioned considerationwas confirmed available for the output faces.
