This study explores to methodology for the service development of the rapidly changing ubiquitous environment, on the assumption that the tag-based context-awareness technology turns into the most important concept in services provided by ubiquitous halls. First, this study delves into tag technology in the ubiquitous environment. Second is to conduct surveys into inconveniences and things to improve in ubiquitous halls, relating to exhibition space, and to analyze them. Third is to conduct surveys into inconveniences and things to improve in ubiquitous halls, relating to exhibitions, and to analyze them. Fourth, this surveys are conducted to look into inconveniences and things to improve in ubiquitous halls, relating to user groups of the halls, and analyze them.
