This paper proposes a new approach for the analysis of a customer's initial impressions of an automobile front view. It is important for manufactures to analyze the differences in the expression that a studied automobile provokes in the viewer. We have tried to estimate quantitatively both the “facial expression” and the “perceived age” using modals that are already in common usage, for fifty automobile front views. Two visual stimuli were used in our experiments: the drawings and the caricatures generated by an automotive caricaturing system coche-PICASSO. The results show that this approach is effective in analyzing motor vehicle viewer perception.

“Resolution” in music theory means the chord progression by the transition from dissonance to consonance for providing more profound satisfaction to listeners than consonant chord only. The authors have investigated similar effects in temporal color transitions as an analogy of musical perception’s effect. In Part (1), the authors used various display patterns of three-colors combinations, measured the score of the color consonance with a sensory test, and revealed conditions where the “resolution” effect is enhanced. In Part (2), the authors focus on the conditions of gaze control. The fixation point appears as a small white dot on the black screen, and the observers are advised to fix their gaze onto the point. The white dot continues to appear while the observers watch the color arrangements and the transition. The experimental results suggest that the “resolution” effect appears more clearly when the color arrangements are captured in peripheral visual fields.

Nagoya Cochin is one of Japan’s famous chicken breeds and was also the first domestic commercial chicken. The eggshell is a pink cherry-blossom color, with white speckles on its surface. The purpose of this study is to develop an eggshell color index for quality control to improve the commercial value. This study consists of two experiments. In the first experiment, the eggshell color of sixty eggs was measured by a colorimeter TC-8600A, and a visual evaluation using photo images of each egg was conducted by fourteen visual inspection experts. They scored on a Likert scale of five steps on four criteria: attractiveness of color, attractiveness of white speckles distribution, overall attractiveness, and preference. The relationship between the eggshell color and the visual impression was analyzed on a Hunter Lab color space. In the second experiment, a range of color variations of eggshells were generated on a screen using Adobe Photoshop, and a visual evaluation of three hundred and fifteen egg images was conducted by seven experts. It is hoped the results from both experiments will be useful for agricultural producers to develop more attractive products and increase the commercial value of Nagoya Cochin chickens.
