The Visual Perception of the Aged in the Night : Effect between the Color Attributes and Effect between the Color Aspects

本研究旨在从支持老年人日常行为的中视视觉出发，提出暗视视觉中的环境色彩。制作了检验颜色属性间效果的检验容器。该设备视角为10°，有3种光源（白光、日光、地平线阳光）可调节光照量，有3个运动轴，可对其设置刺激。采用5种柱（柱高30mm，柱径20mm ~ 60mm）作为固体刺激。刺激物的颜色构成了JIS安全色中近似的四种颜色。色度分别为8.4R 3.9/15.3, 4.2PB 3.3/9.0, 1.1Y 7.4/13.1, N6.5。标准的固体刺激是固定的。测试对象观察到一个固体刺激，它前后移动。测量两种刺激物似乎处于同一位置时的距离。考察色彩方面之间的效果，采用了多张彩色芯片（40mm × 40mm， 49张），其中孟塞尔色相、孟塞尔值、孟塞尔色度不同。当它和标准刺激物处于同一位置时被试倾向于识别它当被移动的刺激物离标准刺激物有一定距离时。而对于直径为20 mm的小型固体刺激，视觉检测差异较大。与红色和蓝色相比，黄色和灰色是视觉检测差异增大的趋势。认为环境（背景）颜色的明暗影响了检测容器内壁颜色与灰色刺激相同时视觉检测刺激的差异。老年人的色彩感觉（例如，在这种情况下，浅色的感觉，厚重的感觉，温暖的感觉或寒冷的感觉），一种近似的趋势（高亮度，低饱和度）。但是，高饱和度的颜色，如红色、黄红色、黄色和黄绿色，在分类悬浮组中是根据重量的感觉来分类的，在温暖组中是根据温度的感觉来分类的。少

This research aims at proposing the environment color in scotopic vision from mesopic vision which supports the daily behavior of the aged. The inspection vessel to examine effect between the color attributes was made. The view angle of this device is 10°, and it has 3 kinds of illuminants (white, daylight, horizon sunlight) which can adjust the amount of light, and has 3 movement shafts, to which a stimulus can be set on. 5 kinds of columns (Height : 30 mm, diameter : 20 mm - 60 mm) were used as the solid stimulus. The color of the stimulus made four colors of the approximation in the safety color by JIS. Chromaticity are 8.4R 3.9/15.3, 4.2PB 3.3/9.0, 1.1Y 7.4/13.1, N6.5 respectively. The solid stimulus of the standard is fixed. The subject observes a solid stimulus for the examination that it is moved in front and back. The distance when it seems to be the position where both stimuli are the same is measured. The examination of the effect between the color aspects used the color chip … More s (40 mm × 40 mm, 49 sheets) which Munsell hue, Munsell value, Munsell chroma were different from.The subject tends to recognize it when it is the same position as the standard when the stimulus that it is moved is in the distance from the standard stimulus. And, the difference in visual detection of the small solid stimulus (Diameter : 20 mm) is comparatively big. The tendency that the difference in visual detection grew big was recognized as yellow and grey in comparison with red and blue. It thinks that lightness of the environment (background) color influenced the difference in visual detection of the stimulus from the color of the wall in the inspection vessel being the same as the stimulus of grey. A feeling of the color of the aged showed (for example, in such cases as a light feeling, a heavy feeling and a warm feeling or a cold feeling), an approximate tendency (high lightness, low saturation). But, the color of high saturation such as red, yellow red, yellow and yellow-green is classified by a feeling of the weight for the classified suspension group, and it is being classified by a feeling of temperature in the warm group.
