This paper presents the subjective evaluations of multiple observers as part of an investigation into the relationship between CG parameters of digital mockups and visual sensibility. In our experiments, the specular appearance of CG imagery is reproduced on an actual mockup using a projector-camera system. The specular intensity and position are evaluated in terms of magnitude and inauthenticity. For the specular intensity evaluation, it was found that changes to specular intensity in the CG parameters were equal to the changes in the brightness sensibility of the object viewed. Furthermore, the results of inauthenticity evaluations clarified the limitations of the viewpoint range. The specular appearance from the 60° viewpoint gave observers the impression that the form and position of the specular reflection were inauthentic. Therefore, it was determined that the control of appearance in our digital mockup was only suitable for observations within the range from -45° to 45°.
