Abstract
In this time, commercial products change "physical goods" to "user experience." In this paper, I think "user experience" is so called "service." Some researchers proposed "Service science" which will raise the curtain of this "service." Otherwise design research theme expand not only traditional design field like "products design" or "graphic design" but also "information design" or "user experience design." I feel "Human centered design" or "User centered design" are very useful to this issue.The purpose of this paper is to investigate practical cases and former researches, after that build the frame of "service design methodology research." In the last part, I propose future research plan about this theme.This research will co-operate both of academic field and business field.
