Investigation of Color Images and Visual Responses of Electroencephalograms to Wooden Flooring

使用木材作為地板裝修是國內室內裝潰常見且是很重要的選項，本研究進行心理及生理方法探討木質地板給予人的感受。首先選用五種主要商用地板區別其色彩，並進行問卷調查，結果發現以秘魯膠樹地板最受消費者喜愛佔44%，而最不喜歡的是硬械地板佔受訪人數之46%。在舖設地板空間之滿意度方面，則木質地板相較於磁磚地板舖設空間給予人在放鬆、舒適、溫暖等心理意象上及第一印象均有高滿意度之評價。在量化均一色彩空間中祕魯膠樹偏紅且明度較低、硬械偏黃且明度較高。受測者在觀察不同地板空間的腦電波圖顯示，α波主要反應位置是在大腦枕葉區，且受測者在閉眼後之α波活動較睜眼期間增為3倍以上，具良好之反應性。在觀察木質地板空間時所產生的α波反應與臨磚地扳空間有顯著的不同，但祕魯膠樹地板與硬誠地板間之α波反應則無顯著差異，但男女受測者間略有不同。受測者在觀看不同地板時，其α波發生最大活動之頻率是在8Hz，當閉眼後會移至11~12Hz。

Using wood as a flooring finish is a common and important selection for local interior deco-ration practice. Human's feelings and feedback from wooden flooring were investigated through psychological and physiological approaches in the study. A survey with a questionnaire was used to assess the preference of flooring materials among 5 major commercial wood species of various colors. Results indicated that the most favorite wood flooring was made of red incienso, i.e., 44% of interviewed adults, while the least favorite flooring was made of hard maple for 46% of interviewed adults. As to satisfaction with rooms in which different flooring material was installed, high scores were obtained for the psychological images of relaxation, comfort, warmth, and the first impression for wooden flooring compared to ceramic tile flooring. As to colorimetric characteristics of wood in a uniform color space, red incienso flooring material was close to a red color with a lower value of lightness, while hard maple was close to a yellow color with a higher value of lightness. From the electroencephalogram measurements when viewing a room in which different flooring materials were installed, major a activity was found in the brain's occipital region, and the power of α activity measured when subjects closed their eyes was 3 times that measured when the eyes were open. The α activity measured when subjects were viewing a room in which wooden flooring was installed significantly differed from that when viewing a room covered with ceramic tile flooring. No significant difference in subjects' α activity was found between rooms with red incienso and hard maple flooring materials, but there may have been different responses to flooring materials between males and females. It was found that the highest α activity or amplitude occurred at 8 Hz when subjects were viewing rooms with different flooring materials, and shifted to around 11 and 12 Hz when subjects closed their eyes.
