Study on availability and utilization of the picture images for the communication of information in life, especially in advanced aged society

为适应老龄化社会的到来，研究了图片图像在生活信息交流中的可用性和利用问题。从基础研究和应用研究两个方面对颜色、图案和三维图像的知觉和检测机制进行了研究。为了设计老年人的交通标志和服装，研究了反光镜的表面结构对测角仪反射和受试者能见度的影响。使用计算机模拟在触摸屏上设计图像来估计售票机的操作。特别是在紧急情况和地震的情况下，调查了日本20个城市的EVES信息交流的照明条件。针对图像信息的可用性，研究了计算机网络上的主页设计。估计了摄像机到三角形的相对位置和方向。

Availability and utilization of the picture images for the communication of information in life were investigated for the advanced aging society. The mechanism of perception and detection of color and pattern, and 3-D images were examined on fundamental and applied studies. The effect of the surface structure of retroreflectors on reflection using goniophotometer and on visibility by the subjects were examined for the designing traffic signs and clothing for old people. Operating the ticket machines were estimated using computer simulation for designing the images on the touch panel. Especially at the case of emergency and earthquake, the conditions of illumination for the communication of information by eves were surveyed at the twenty cities in Japan. Home page designs on computer network were studied for the availability of image information. The relative position and onentation the camera to a triangle were estimated.
