Abstract

Recent information technology enables us to use fragrance as media content. Additional use of fragrance to information of sight will achieve higher effects in new products and Web browsing than ever. Referring to the previous studies, this study fundamentally investigated the effects of combination of color and fragrance. To investigate the effect, two experiments using color and fragrance were conducted. In the experiment 1, eleven subjective evaluations on each six color and each ten fragrance were obtained. The experiment 2 investigated the effect of combining the colors and the fragrances, and the number of the combination was sixty. Twelve subjects participated in both of the two experiments. Effect of each color and each fragrance was investigated with Freedman test in both of the experiments. In the result of the experiment 1, significant effects of color or fragrance were observed in all eleven adjective pairs. In the result of the experiment 2, significant effect of color and fragrance were observed in most of evaluation indices. By comparing these results, change in evaluation value by combining color and fragrance from presenting only color or fragrance was investigated with Sign test and Holm's test. Significant changes in evaluation value by the combination were shown in many cases, and most of them were affected by adding fragrance on color. In contrast, significant changes caused by adding color on fragrance were observed in only six cases.
