Abstract
The reason is because it is thought that I am different in a tendency to feel that it is easy to use it with a subject of the old stratum, a subject of the non-old stratum each. I studied a difference of an image of usability to be able to put between these generations. I felt that the old stratum, a subject of the non-old stratum were easy to use it for any kind of operation by this and clarified whether I felt that I was hard to use it. From all evaluation experiments, a result of analysis, I clarify the old stratum, a tendency of interface to feel that it is easy to use it in the class of non-advanced age and do it with a point of a design. And I suggest the design which improved an interface design of a ticket vendor from results of research of a related study and this study.
