In this talk, I will report about our new ideas on extending the scope of collaboration not only from desktops to meeting room support but taking a more comprehensive perspective resulting in highly flexible and dynamic work environments. This perspective is provided by the notion of "cooperative buildings" which addresses the issues of how to integrate information technology, new work practices resulting from organizational innovation, and the physical environment, the architectural structures and facility management. It incorporates also ideas from augmented reality and ubiquitous computing.

In order to illustrate this, we have developed i-LAND: an interactive landscape for creativity and innovation. i-LAND integrates several so-called "roomware" components into a combination of real, architectural as well as virtual, digital work environments for creative teams. By "roomware", we mean computer-augmented objects in rooms, like furniture, doors, walls, and others. The current realization of i-LAND covers an interactive electronic wall (DynaWall), an interactive table (InteracTable), two versions of computer-enhanced chairs (CommChairs). More components are planned; i-LAND is an example application of our vision of the Workspaces of the Future. At the same time, it is a testbed for developing new forms of human-computer interaction and computer-supported cooperative work.
