Tracking and presenting user attention for collaborative browsing using heterogeneous devices

This paper presents mSpiders, a system that extends traditional co-browsing to support mobility and awareness among participants. The system offers mobile users the ability to easily get help and share web documents with others over the Internet and greatly enhances users' Web-sharing experience. By introducing a new method to track and present the current attention of each participant - their region of interest (ROI), the system enables all participants aware of each other's presence and what they are viewing, independent of the specificities of Web content, browsers used and their settings.
