We present the ConnecTable, a new mobile, networked and context-aware information appliance that provides affordances for pen-based individual and cooperative work as well as for the seamless transition between the two. In order to dynamically enlarge an interaction area for the purpose of shared use, a flexible coupling of displays has been realized that(More)
We describe the i-LAND environment which constitutes an exampleof our vision of the workspaces of the future, in this casesupporting cooperative work of dynamic teams with changing needs.i-LAND requires and provides new forms of human-computerinteraction and new forms of computer-supported cooperative work.Its design is based on an integration of(More)
Drag-and-pop and drag-and-pick are interaction techniques designed for users of pen-and touch-operated display systems. They provide users with access to screen content that would otherwise be impossible or hard to reach, e.g., because it is located behind a bezel or far away from the user. Drag-and-pop is an extension of traditional drag-and-drop. As the(More)
In ubiquitous computing environments, multiple users work with a wide range of different devices. In many cases, users interact and collaborate using multiple heterogeneous devices at the same time. The configuration of the devices should be able to change frequently due to a highly dynamic, flexible and mobile nature of new work practices. This produces(More)
In this paper, a conceptual model for synchronous applications in ubiquitous computing environments is proposed. To test its applicability, it was used to structure the architecture of the BEACH software framework that is the basis for the software infrastructure of i-LAND (the ubiquitous computing environment at FhG-IPSI). The BEACH framework provides the(More)
In this paper, we provide background information on the video shown at UbiComp'02. This video is a revised version of the one shown at CHI'02 [3] and provides an extensive presentation of the second generation of roomware ® components. Compared to the first generation, the redesign, resp. new design and implementation resulted in a comprehensive environment(More)
