RESUMO

The variety of ways by which people interact have dramatically changed in the recent years. The conception of new teamwork paradigms has encouraged the creation of innovative collaboration technologies. This fact has led to the dynamic collaboration scenarios faced nowadays. Amongst these recent paradigms, there is one called collaborative web browsing (co-browsing) paradigm. Collaborative systems that implement such paradigm provide a useful way for virtual groups to share information through the web. However, the common set of features in these tools is not enough to offer a more face-to-face-like browsing experience. To fill this gap, this work presents a novel collaborative web browsing proposal, which aims at integrating notably three important characteristics. Firstly a flexible management of sessions, which allows the involved participants (i) to contribute freely or hierarchically to the teamwork, but also (ii) to prevent confusion or waste of work effort. The second characteristic refers to the maintenance of a shared production spaces for co-browsing sessions. At last, providing efficient communication facilities. In this case, such efficient communication are accomplished by annotations (i.e.: draw and text note elements over co-browsed contents) and privileges negotiation facilities. Additionally, the proposed environment analysis relies on a collaboration ontology as a reference model, which provides a well defined conceptualization and a common vocabulary about the collaboration domain. Another characteristic explored in this work involves an architectural solution for supporting suitable performance, regarding the system response time perceived by participants and how effective is the maintenance of awareness in the co-browsing sessions. Such challenges are met by the design of a lightweight distributed architecture and communication protocol. In order to demonstrate the feasibility of our approach, a prototype is developed and its performance issues evaluated
