The Knight Project: Supporting Collaboration in Object-Oriented Analysis and Design Abstract Object-oriented analysis and design benefits from active collaboration between developers and users. Based on user studies of collaborative modelling practice, we are developing a tool, called Knight, for supporting this active collaboration. By combining a large shared screen with gesture recognition and zoomable interfaces, Knight allows the collaborative construction of UML based models mixed with informal drawings. This position paper thus presents a novel approach to narrowing the gap between developers and users.
