Abstract This thesis presents an novel image management system { nTag. It targets smartphone users, who are supposed to confront the trouble in managing a large collection of images when the time of mobile image explosion arrives. The current version runs on Nokia S60 platform, works with a GUI and is controlled via conventional mobile phone numeric keypads. nTag provides users with tags to describe images, and images who have the same features are likely to be described by the same tag. In this way, nTag accomplishes image classication and organization using tags. Moreover, the nTag system also introduces a search engine helping users quickly locate images. It adopts a method dedicated to tag searching on numeric keypads, which is operated similarly to "T9" mobile input method, but is better than the latter. The whole development process of nTag is a practice of software engineering theory, from the domain analysis until software implementation and test. Finally, nTag is evaluated by three means: a series of software testings, an usability experiment, and a functional comparison with other image management solutions on mobile devices. From these evaluations, it can be seen that nTag is a dependable and useful product with high performance. It can locate images 20% faster than Nokia N73's tagging solution and more than 4 times faster than conventional image browsing method on average. nTag is user friendly and people can easily put hands on it without the manual.
