The Research On How To Use Usage Centered Design Method In P2P TV Player Interface Design Process

With the development of Internet and the video data transmission technology, P2P TV industry is booming up in China recently. Compared with traditional TV player, P2P TV contains hundreds of thousands of video resources and provides several different ways for playing program. Rich interaction and customized user interface are two most important features of P2P TV. So the design of P2P TV player's user interface becomes an important but pendent topic for P2P TV suppliers. As entertainment software, P2P TV player's interface should not only abide by the usability theory, but also provide excellent user experience. Therefore, this thesis addresses how to design the user interface of P2P TV player to meet the user experience requirements. I propose a usage centered design method to mine the users'behavior patterns and psychological demands and carry out the methodology during the graphic user interface designing.In the beginning, I briefly review the definition, category and architecture of human computer interaction. Then I introduce the P2P TV player's definition and related technology to help the reader setup a basic concept about P2P TV player and the underlying technology.Then my thesis concentrates on the usage centered design. Usage centered method applies the abstract models to describe the user target and use case and then convert these models to graphic user interface. Because it's not enough to measure the user experience as well as such emotional factors, I enable Persona to make up for the insufficiency of usage centered design.At the research and data analysis stage, I present the objective user of P2P TV player and the method used in the data collection. After data analysis, I get the essential behavior variables and patterns of the objective users, which are the ground for role modeling and target modeling.In the end, my thesis shows the specific procedure of the P2P TV player's design and gives the final result. I summarize the differences between usage centered design method and the other general design methods and conclude that it can get better effect to take the usage centered design for designing the creative user interface design.
