Study Of Information Architecture Of Portable Multi-media Player User Interface

To improve the usability of portable multi-media player (PMP) when the integrated techniques and functions stand out, the paper explores the general design principle and method of information architecture (IA) of PMP user interface, while the traditional product design method focuses on the relation between function and form. The young college students are selected as the target user based on the analysis of questionnaire. The whole study is based on the case study and user experiment.First, in order to summarize the basic design characteristics and reference principle of IA, the study of IA of portable digital radio players' user interface is carried out in three aspects: task menu, task definition and task menu structure.Then, through the task analysis, card sorting and focus group, a design sample of IA is put forward based on the target user research, and the design process and method of IA are explored.At last, prototype experiment is done in a way of task analysis after making two sample prototypes. The average time and "t" measure are done based on the analysis of experiment data, at the same time, the user cognition is studied during the experiment.According to the case study, analysis of experiment data and user cognition, the paper put forward the general design characteristics and principles of IA of PMP user interface, and the common properties of user cognition are outlined.
