Abstract

Product emotional quality consists of sensory information perceived through five senses by nature. Most conventional works in design for emotional quality have dealt with only one sense, e.g. a product color as a visual perception and a product sound as an auditory perception. There is an implicit assumption that the sensory information between different senses is independent in such works. However, sensory information of different sense may interact with each other. Sense of harmony between color and sound is an example of such interaction. In this paper, we discuss sense of harmony between product sound and product color as a product emotional quality based on experimental approach. We also discuss weights of each sense towards total emotional quality. We select a vacuum cleaner as case-study. We conduct two sensory tests based on SD method. In the first test, we show subjects multiple samples having different color and sound and ask them to evaluate them in terms of given emotional qualities. Using the result of the first test, we quantify the weights of each sense towards total evaluation of emotional quality and interaction between senses. In second test, we use evaluation samples that satisfy set design parameters of color and sound, in order to formulate the multi-modal emotional quantities. Based on the result of the test, we establish an assumption that sense of harmony between color and sound changes depends on sound sharpness, which is quantitative value of sound quality metrics. Using factor analysis, we found that the sharpness maximizing sense of harmony correlate with 2^<nd> factor of color, which is meaning sense of activity. We formulate the relation between 2^<nd> factor of color and design parameters of color and sound.
