While the technology keeps improving, the market of mobile services seems to be at a standstill. The reasons are mainly because of the impression of low-speed Internet connection, high-cost of transmission bandwidth and the lack of interface usability of the services provided. The users are more likely to embrace and pay the services only when the usability of the services is improved. The major usability problem of the image retrieval service lies in the searching method based on text description. Therefore, Content-Based Image Retrieval (CBIR) is used to improve the usavility and efficiency. In this study, the principles of usability to design software and Wireless Application Protocol (WAP) services are studied and concluded. They are used to develop an image retrieval service on mobile phones. CBIR and Scenario-Based Design are introduced to the design flow of the prototype service. To induce the users’ needs, expected functions, visualization of information and detailed user interaction, a sequence of stages of “analysis”, “design” and “implementation” is executed. The result is an image query and download service based on the content specified by the user. Evaluation is also performed to reveal what are improved by our usability principles used in the design process.
