TOWARDS AN ENHANCED ADAPTABILITY AND USABILITY OF WEB-BASED COLLABORATIVE SYSTEMS
Stephan G. Lukosch, Mohamed Bourimi · International Journal of Cooperative Information Systems · 2008
Web-based collaborative systems support a variety of complex scenarios. Not only the interaction among one user and a computer has to be modeled but also the interaction among the collaborating users as well. As a result, the user interfaces of many web-based collaborative systems are quite complex, but hardly use approved user interface concepts for the design of interactive systems. Thereby, web-based collaborative systems aggravate the interaction of the users with the system and also with each other. In this article, we describe how the adaptability and usability of such systems can particularly be improved by supporting direct manipulation techniques for navigation as well as tailoring. The new functionality for tailoring and navigation is complemented by new forms of visualizing synchronous awareness information and supporting communication in web-based systems. We show this exemplarily by retrofitting the web-based collaborative system CURE while highlighting the concepts that can be easily transferred to other web-based collaborative systems.
