Preferably, the values of the forces F or the components Fin a specified period Zbetween a time Tand a time Tafter the impact are obtained in time series in the first step. Preferably, the hit feeling is evaluated based on an integrated value Sf of the forces F or the components Fin the specified period Zin the second step.
