The main goal of this study is to understand factors in implementations of mobile guide systems in exhibitions and to discuss how ¡§ fit¡§ and ¡§viability¡§ perspectives affect the wiliness of exhibitors to implement mobile guide systems. The study begins with interviews with Professor Hong Wanlong and Mr. Zhangjian Zhiting of National Science and Technology Museum, to understand how exhibitors evaluate mobile guide systems. Combined with analysis and induction of perspectives and variables from studies of past journals, sub-perspectives of ¡§ fit¡§and ¡§viability¡§ are built. Then, for a through statistical survey, a questionnaire survey is conducted to explore the wiliness of exhibitors to implement mobile guide systems. Analysis revealed that localization, sufficient storage for databases, mobility and timeliness showed positive correlations between the ¡§ fit¡§ perspective, while financial concern, infrastructure of information technology, support from top management and capability of information technology department showed their positive correlations with the ¡§viability¡§ perspective. However, the ¡§financial concern¡¨ factor showed a lower significance level than others, indicating that for exhibitors the factor is taken into account but not the most important concern.
