It is indicated that there is the high possibility of disagreement between the evaluation of shape in virtual space and that in real space in the previous paper. In this paper, the new virtual system for shape evaluation is proposed which integrates the visual and gazing line-motion linkage information in virtual space and the tactile information in real space. By using the system, the preferences of 3D shape images in the proposed virtual space under some experimental conditions were compared with those of the real photoforming products made from the same data in 28 subjects by the sensory evaluation of paired comparison and the questionnaire analysis. It is found that the preference for shapes is consistent in both spaces in the relation of the preference among shapes based on the Bradley-Terry model in sensory evaluation. This indicates that the proposed system provides almost the same environment as the real space for shape evaluation. The results of questionnaire also demonstrate that the tactile information and gazing line-motion linkage system play the important roles in 3D shape evaluation, and the proposed system is enough to evaluate the 3D shapes in virtual space. These results indicate that the system enables to investigate the desirable qualities of shape evaluation by handling the information of visual, tactile and gazing line-action.
