All of us have no time to predict and prepare for a rapidly-approaching future change in the 21st century, thereby being reality that we feel uneasy about future society. Accordingly, there is necessity for re-consolidating environment and daily culture in preparation for future society, namely, aging society. Given well preparing for super-aging society that will approach in the future, by which this effort becomes what bad luck often brings good luck, our country's role is thought to get probably bigger even in the globally silver industrial market in near future. We need to synthetically recognize a human being's aging psychological and physical conditions through the aging experience exhibition available for publicizing properly this historical phenomenon, and to pay more attention to importance of interaction between a human being and product environment. The experience exhibition is a concept for the exhibition form and the spatial composition, which emphasized interaction, with having escaped from the simply exhibition space. Given trying to communicate information more scientifically with escaping from the conventional exhibition of seeing and listening, it is also important to research Into the basis for exhibition as the experience space based on interaction. After all, a human being's aging is the unavoidably future phenomenon. And, importance of environment, which influences a human being, is very mutual as well. Our country is desired to develop a research on interaction of the exhibition experience space available for broadening recognition of senior-friendly and for properly experiencing this, thereby being an opportunity that the business entity, which plans silver industry, and the academic circles, which research and develop this, do mutually cooperate and can make silver industry grow further.
