Illuminance Level, Readbility and Eye Movements Part I: An experimental consideration of indices for readabiliyt

摘要

In recent years there has been a trend to accurately define the physiological needs of elderly people and design environment to suit those needs. It is important to keep up with the needs of an aging society. One of the most important tasks in designing an appropriate environment for elderly people is the determining a desirable illuminance level for elderly people. In general, the size of characters should be larger or the illuminance level should be higher for elderly people than for young people. However, these ideas are unconvincing because they are not based o nactual physiological functions or behavior characteristics of elderly people. In order to etermine desirable illuminance level for elderly people, it is important to determien a guideline based on actual physiological functions or behavior characteristics of elderly people. In order to determien desirable illuminance level for elderly people, it is important to determien a guideline based on data describing the daily behavior characteristics of elderly people.
