博士 === 國立臺灣科技大學 === 工業管理系 === 93 === Two experiments were executed in this study. The first experiment explored the effects of display characteristics such as target/background color combination, singly/simultaneously presentation type, and individual differences of sex, and design specialty on preferences of VDT icon design. The results indicated that black targets (black-on-white, black-on-yellow) and black backgrounds (red-on-black, yellow-on- black) were the most popular color combination. As for the chromatic color combinations, yellow-on-blue was the most favored. Subjects rated color combinations under Singly Presentation higher than those under Simultaneous Presentation. Woman rated purplish targets and rated purplish background higher than men. Subjects with design background favored black more, either as a target or background, but they favored turquoise less than those without design background. The second experiment investigated the effects of color combination and polarity on subjective preferences and EEG evaluation. The results indicated that subjects favored the color combinations in much the same way as in the first experiment. As for the polarity, the negative presentation was more popular than the positive presentation. When the subjective preference was measured, the results of EEG evaluation indicated that the powers of F4-θ and P4-θ in the right brain were higher than F3-θ and P3-θ in the left brain, and the powers of F4-α and P4-α in the right brain was higher than F3-α and P3-α in the left brain too. In addition, the power of θ and α increased significantly over the midline regions of the scalp (FCZ<CZ<PZ). Also, in the visual evidence, there exists some modality in the channels of F3, P3, PZ, and P4 of the spectral-power plot.
