Development and standardization of accessible design technologies that address the needs of senior citizens

Abstract

With the recent trend of decreased birthrate and increased aging population, design that can be used by as many people as possible including the elderly, or accessible design, has been incorporated in consumer product designs. The authors have developed and propagated accessible design technology through the establishment of Japanese Industrial Standard (JIS) based on auditory and visual functions of elderly people. This paper uses JIS S 0014, a standard for adjustment method of sound volume of auditory signals, to describe the research process that leads to the standardization of accessible design from the perspective of Full Research.
