Handheld devices, like PDAs and mobile phones, are increasingly used to access information on the Web. However, because most Web pages are designed for desktop PC screens whereas these devices have small screens, only a small region of a page is visible at a time. Reading and finding information is therefore difficult and requires extensive amount of scrolling, both horizontally and vertically. One way to address this problem is an overview plus detail approach to the design. We describe SearchMobil, a working system that supports the user in viewing and searching the Web with a PDA. It is based on our SmartView technology that performs content and layout analysis of Web pages and thus provides foundations for SearchMobil features. We present the results of a user study that shows the utility of the SearchMobil approach and provides further insight in challenges and opportunities that the mobile Web presents.
