Color design of luminescent interface display of climate control device

Abstract

The study demonstrates a design process of the color of luminescent surface facilitated by RGB LEDs and shows that both exploratory and confirmatory approaches were synergized to result in a design solution. Focusing on the relationship between color and in-door climate of automobiles, the study consists of three parts: In Part I, a workshop of ten designers was run in which ideas about were exploited to find scenarios. The quality of scenarios was evaluated in terms of interesting, informative, and inspiring aspects to conclusively derive the scenario of “Eco & Healthy Driving”; In Part II, a user test was carried out in order to investigate the relationship between the attributes of luminescent color—hue, brightness, and purity- and a indoor climate condition. In the user test (n= 36), subjects were instructed to match a luminescent color to a given in-car climate condition. It was revealed that the hue category of luminescent surface is related to the temperature while brightness of luminescent color is correlated with the blow level; In Part III, a new design scenario, “Eco & Healthy Driving” was projected for further development and application by employing the results of user test.
