In this paper, we investigated the reliability of reproduction with material appearance by using Ward's model through comparison with perceptual aspect. Four materials, aluminum, rubber, graphite, and ceramic, and three objects, were used in our experiment, and observer controlled two parameters of specular reflectance and roughness. Moreover, the three-dimensional display with eye-tracking control was developed for reproducing the object in order to improve accuracy. As the result of subjective evaluation, the discriminative combination of coefficient exists with each appearance of the material. There is a possibility that each parameter can control appearance of material, since the tendency to change an appearance exists according to the aspect of materials, respectively.
