Activity-Centric Mobile Social Network Service Design Research

At the beginning of a new socialized era, the innovators of Social Network Service try to re-imagine and re-define Social Network Service based on mobile platform, which starts the influence produced by mobile devices and real-time connections. The reason why Mobile Social Network Service removed from Internet has no breakthrough in mobile devices is that it did not find a suitable application system and interaction model. Activity-Centric Mobile Social Network Service from online and based on offline will enrich the interaction between users, which can excavate the internet value of mobile device rather than PC and project the virtual information into the real life by“activity”. It will also enrich Mobile Social Network Service application system and create the models of making friends, then produce user stickiness effectively. Moreover, it can satisfy the double requests between the users and enterprises and produce a new profit model by the combination of the two.This thesis analyzes the effect of remaining and expanding relationship based on the trend of Mobile Social Network Service, describes the online and offline services formed by the Activity-Centric Mobile Social Network Service. It uses the six elements and five core principles of activity theory in psychology to conduct the research of Mobile Social Network Service design, proposes the design models and principles of Activity-Centric Mobile Social Network Service, and constructs the design model. Finally, it introduces the practical process and the final achievement.The innovation of this thesis is taking the sociological theory into consideration when describing the important role and significance of activity. On the other hand, this thesis describes the potential value of Activity-Centric Mobile Social Network Service. Based on the activity theory and combining the mobile device physical characteristics with the user cognitive characteristics,the result of this study leads to the whole new Activity-Centric Mobile Social Network Service design model. It may serve as a reference for the future development of Mobile Social Network Service design.
