With the help of that program, the user can specify his/her preferences simply by visual manipulations. After finishing the job, preferences about this page will be sent back and stored in a database for later use (Line 2).Fig. 2.

Since the user would configure the browser on his/her mobile device to use a proxy included in our system, we would snoop each HTTP request and modify its corresponding response (Lines 3 and 4) in between. For example, if the user visits a Web page that has been personalized before, some actions would be taken to tailor the Web page to meet the user preferences.Fig. 3.

The purpose and functions of each ponent will be introduced separately. System design details are presented in Section 3..

However, most of the web pages were designed for desktop puters equipped with big screens. When browsing on mobile devices, a user has to scroll up and down to find the information they want because of the limited screen size. Some mercial products reformat web pages. However, the result pages still contain irrelevant information. We propose a system to personalize users’ mobile web pages. A user can determine which blocks in a web page should be retained. The sequence of these blocks can also be altered according to individual preferences.1. Introduction. PrefaceNowadays, we can build a mobile Web application easily. Take the ASP. NET mobile controls [1] (formerly known as MMIT, short for the Microsoft Mobile Internet Toolkit) for example, it reduces the work required for developers to develop applications that target different types of mobile devices, like mobile phones and PDAs. At runtime, MMIT will automatically detect the target device and return the proper presentation format. Thus, the developers can focus on the application logic without worrying about the presentation issues. Similar academic researches on this topic include [2] and [3]. Both of them provide plugins for famous IDEs, such as JBuilder and Visual respectively, to assist developers to author a single generic application. Acpanied with the PUML transformation technology [4], this generic application can be further transformed into specific target formats for different mobile devices.. MotivationWidespread of mobile devices makes it mon to browse Web pages via them. However, most Web pages are mainly designed for desktop puters that are equipped with big screens. When browsing on mobile devices, a user might have to scroll up and down, left and right all the time to find the information they want. Because of the limited screen size, this kind of operation is really not userfriendly at all.Fortunately, some famous websites have another simplified version of Web content specially provided for mobile devices, such as Google Mobile [5] and Yahoo Mobile [6]. On the other hand, it is a heavy burden on Web developers to craft and maintain multiple versions of the same website. Even with the help of the fascinating toolkits.If we resize the original Web page to fit the width of mobile device, the vertical scroll bar will be too long to view, and the information is crowded. On the other hand, if we provide another version of the original Web page, there may be some important information lost in the mobile version, and the transformation of each page costs a lot for Web page developers. Hence, in this research, we propose a system that is designed to help users to personalize their mobile Web pages for handheld device browsing.. Research objectivesIn this subsection, the four major research objectives are listed and introduced briefly.
