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

本研究旨在补充老年人夜间的视觉感知信息和色彩环境的安排，以支持老年人的日常生活。我们最初为这项研究制造了光源设备，在其中可以改变光源的条件。实验对象由几种木质固体刺激物组成：柱子、半柱、圆锥体、三棱柱、四角锥体、立方体和土制玩偶。对于老年人的实验，使用彩色纸覆盖的木制品的固体刺激物。刺激物的颜色为红、黄、蓝，这些颜色是基于日本工业标准(JIS)的安全颜色。以日光和地平线阳光为光源。对于固体刺激的形状测量，采用非接触式三维数字化仪器(MINOLTA VIVILD700)，采用激光扫描的方式。日落后的视觉环境是…第一年在实验室里复制的更多。考察了光学环境改变时固体刺激对形状传递的影响。最后一年进行了老年人对固体刺激的视觉知觉实验。考察了颜色对视力的影响，以及在“亮”和“暗”两种情况下的视觉表现。对于固体刺激的形状识别，刺激位置的光量比离眼睛刺激的距离更重要。并且，在视觉观察的情况下，固体刺激的边缘数目影响形式识别。在这种情况下，刺激的边缘数为柱状：4，半柱状：5，正方形：7，三棱镜：8，当立体刺激的形式为柱状和锥状时，可以获得良好的视觉性能。特别是在“柱、日光、[R]/Y”的条件下，表现出较好的视觉效果。换言之，是白天(亮)、“柱”、“红色标准刺激”、“黄色运动刺激”的情况；另一方面，是“立方体、地平线日光、暗淡、[Y]/Y”、“柱、地平线日光、暗淡、[B]/B”等条件导致视力成绩下降。也就是说，地平线上的阳光(暗淡)，“所有标准刺激和运动刺激都是黄色的立方体”，“两个刺激都是蓝色的柱子”，在夜间有效地使安全的色彩环境保持良好状态的颜色是来自老年人情况的红色和黄色。此外，还表明柱体和锥体作为固体形式具有较高的观赏性能。较少

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
