Abstract

To improve and optimize user interfaces of the system, the accurate understanding of users' behavior is an essential prerequisite. In this paper, we described the work which examines users' behavior through log analysis in their own environment. 50 users were recruited by consumer segmentation and logging-software was downloaded in their mobile phone. After two weeks, logged data were gathered and analyzed. The complementary methods such as a user diary and an interview were conducted. The result of the analysis showed the frequency of menu and key access, used time, data storage and several usage patterns. Also, we found the possibility that users could be segmented into new groups by their usage patterns. The improvement of the mobile phone user interface was proposed based on the result of this study.
