项目摘要

Both the number and proportion of older people are increasing in the population of Japan. Therefore, an overwhelming majority of older people can easily manage in the community when given appropriate social supports. One of these support system is environmental or architectural barrier free design, especially, clear sign colors and intensive interior or exterior color design for the aged vision.Aging is a lifelong process beginning from the moment we are born. In each stage of the life cycle there are normal and irreversible physical changes, which are not related to accident or disease. A person experiences normal sensory changes. The failure of vision with age results from changes in the eye itself. Three major changes affecting vision begin to occur in the mid-fifties. The lens of the eye becomes increasingly rigid and opaque. It also gradually yellows and by this or other reasons the color vision of the aged changes. In former papers, we investigated Japanese old adults for their yellowing and clouding of the lens resulting in vision problems, i.e. the loss in one's ability to discern color intensities clearly ; and selected films to simulate age-related yellowing levels. In this paper, we investigated open space, such as pedestrians' way and parks, where elderly people come frequently and colorimetried paving. And also we colorimetried 93 marketable exterior paving colors' samples and 460 color charts for architectural design. After analyzing those colors in the color distribution of the xy-chromaticity diagram, we concluded that safe and healthy color selections could be possible, because mutual brightness contrasts are effectively discerned.

日本人口中老年人口的数量和比例都在增加。因此，绝大多数老年人在得到适当的社会支持后，可以很容易地在社区中管理。这些支持系统之一是环境或建筑无障碍设计，特别是针对老年人的清晰的标志颜色和密集的室内或外部色彩设计。衰老是一个终生的过程，从我们出生的那一刻开始。在生命周期的每个阶段，都有正常的和不可逆转的生理变化，这些变化与意外或疾病无关。一个人会经历正常的感觉变化。视力随年龄增长的衰退是由于眼睛本身的变化造成的。影响视力的三个主要变化在五十年代中期开始发生。眼睛的晶状体变得越来越僵硬和不透明。它也会逐渐变黄，由于这个或其他原因，老年人的颜色视觉会发生变化。在以前的论文中，我们调查了日本老年人导致视力问题的晶状体变黄和混浊，即丧失清晰辨别颜色强度的能力；并选择电影来模拟与年龄相关的变黄水平。本文调查了老年人经常光顾的人行道、公园等开放空间，并对其进行了色彩化铺装。并对93个市面铺装颜色样本和460张建筑设计色卡进行了比色。在分析了XY色度图的颜色分布中的这些颜色后，我们得出结论，安全和健康的颜色选择是可能的，因为有效地识别了相互的亮度对比度。
