Domain Name Based Visualization of Web Histories in a Zoomable User Interface

Abstract

Users of hypertext systems like the World Wide Web (WWW) often find themselves following hypertext links deeper and deeper, only to become "lost" and unable to find their way back to the previouslyvisited pages. We have implemented a web browser companion called Domain Tree Browser (DTB) that builds a tree structured visual navigation history while browsing the web. The Domain Tree Browser organizes the URLs visited based on the domain name of each URL and shows thumbnails of each page in a zoomable window. A usability test was conducted with four subjects.
