Research on the relation between the recognition of the solid form and "the effect on sight and the sight performance" of the color : In the case of the aged in the night

本研究的目的在于补充视觉感知的信息，并对夜间的色彩环境进行布置，以支持老年人的日常生活。我们为这项研究原创了光源设备，其中可以改变光源的条件。实验对象为圆柱、半圆柱、圆锥、三棱柱、四棱锥、立方体、土娃娃等木质固体刺激物;老年人实验对象为覆盖彩纸的木质固体刺激物。刺激物的颜色是红色、黄色、蓝色，并且这些是基于日本工业标准（JIS）的安全颜色。光源采用日光和地平线阳光。固体刺激物的形状测量采用非接触式三维数字化仪（MINOLTA VIVID 700），采用“激光束扫描方式”， 关于我们 第一年在实验室里复制。研究了光学环境变化对固体刺激物形状透射的影响。最后一年进行了老年人对固体刺激物的视知觉实验。考察了颜色对视觉的影响以及在“明亮”和“昏暗”条件下的视觉表现。对于固体刺激的形式识别，刺激位置的光量比从眼睛到刺激的距离更重要。并且，在视觉观察的情况下，立体刺激的边缘的数量影响形状识别。在这种情况下，刺激物的边数为一个圆柱：4，半个圆柱：5，方锥：7，三棱柱：8，当固体刺激物的形状为圆柱和圆锥时，可以获得良好的视觉性能。特别是在“圆柱、日光、[R] /Y”条件下，显示出良好的瞄准性能。换句话说，是日光（明亮）、“柱”、“红色标准刺激”和“黄色运动刺激”的情况。另一方面，是诸如“立方体、地平线日光、昏暗、[Y]/Y”和“柱、地平线日光、昏暗、[B]/B”的条件，视力性能下降。换句话说，这是地平线阳光（黑暗）的情况下，“立方体，所有的标准刺激和运动刺激是黄色的”，和“列，这两个刺激是蓝色的”。在把在良好的条件下，在夜间的安全色彩环境是有效的颜色是红色和黄色，从老年人的情况。此外，有人认为，柱和锥的视线性能高，作为一个固体形式。少

This research aims at the supplement with the information of visual perception and the arrangement of color environment in night in order to support the daily life of the aged. We made originally the light source equipment for this research, in which it is possible to change the conditions of the light source. The objects used for the experiment consist of several kinds of wooden solid stimuli ; a column, a half-column, a cone, a triangular prism, the quadrangular pyramid, the cube, and the doll made of the soil.As for the experiment of the aged, the solid stimulus of the wooden products covered with the colored paper was used. The colors of the stimuli are red, yellow, blue, and these are based on the safety color of Japanese Industrial Standard (JIS). As illuminant were used daylight and horizon sunlight. For the form measuring of the solid stimulus was used the non-contact 3-D digitizer (MINOLTA VIVID 700) in "the way of laser beams scanning".A sight environment after the sunset was … More reproduced in the laboratory in the first year. It was examined about effect on form transmission of the solid stimulus when an optical environment changed. An experiment about the visual perception of the solid stimulus by the aged subject was done in the final year. It was examined about the effect on sight of the color and the sight performance under the condition such as "bright" and "gloom". The amount of light of the stimulus position is more important about the form recognition of the solid stimulus than a distance to the stimulus from the eye. And, the number of edges of the solid stimulus influences form recognition in the case of the visual observation. In this case, the number of edges of the stimulus is a column : 4, half-column : 5, square gimlet : 7, triangular prism : 8, It could get good sight performance when the forms of the solid stimulus were a column and a cone. Especially good sight performance was shown on the condition of "Column, Daylight, [R] /Y". In other words, it is the case of daylight (bright), "the column", "the red standard stimulus", and "the yellow movement stimulus".On the other hand, it was a condition such as "Cube, Horizon Sunlight, Gloom, [Y]/Y" and "Column, Horizon Sunlight, Gloom, [B]/B" that sight performance declined. In other words, it is the case of horizon sunlight (gloom), "the cube that all standard stimuli and movement stimuli are yellow", and "the column that both stimuli are blue".The colors which are effective in the putting in good condition of the safe color environment in the night are red and yellow from the situation of the aged. Furthermore, it was suggested that the sight performance of the column and the cone was high as a solid form. Less
