Abstract
In order to simplify the difficulty in using public lavatories for blind and vis ion-impaired persons, questionnaires and interview investigations were carried out. The result shows that 75.1% of blind and vision-impaired persons could use a lavatory alone, however, 85.2% of men and 97.0% of women feel inconvenience. The most difficult tasks are "finding a lavatory", "distinguishing between men and women" and "flushing the toilet". "Finding the urinal" and "finding the washstand" are particularly difficult for bl ind persons. A standard for planning is requested in order to simplify the use of lavatory facilities for blind and vision-impaired persons.
