The arrival of the 3G era, not only promotes the rapid development of internet, but also affects the needs of users. Music becomes an active power in the traditional internet and mobile internet in various ways. As the most dynamic and exciting users of mobile phone, university students are the main user group of mobile music, and they put forward a higher demand in music function and interaction, that is they seek to the emotional communication with other people while they reach the individual entertainment, in order to meet the needs of interactive experience.The current study, using object-oriented design methods, by the progressive sequence of user and application fields research, user profiles creation, requirements definition, framework definition, interface prototype design, assessment and improvement, researches the interaction design of mobile music sharing. This paper analysis of existing main interactive ways of sharing music firstly, then to do user research through the analysis of characteristics, user interviews and questionnaire investigation, and obtains integrated, active sharing and access three types of users through cluster analysis of the results of user research, then to build the appropriate user profiles, determines the primary persona by comparing their goals and scene analysis, thus defines requirements. After that, this paper obtains two kinds of active sharing and access interactive modes, on this basis, integrates with other functions related to mobile music, such as contacts and information, analyzes the interaction of mobile music sharing and puts forward a feasible interactive proposal. Finally, this current study through the higher-fidelity interface prototype’s usability testing, finds out the existing problems in the design, then,improved by the author.The main innovation of this research is that it puts forward a new user-centered interactive solution of mobile music sharing for university students. The design flow also can be applied to the cell phone video sharing, picture sharing and so on. Lastly, the current study can propose direction for the future mobile phone design.
