Group work frequently involves transitions between periods of active collaboration and
periods of individual activity. We aim to support this typical work practice by introducing four …

Indirect input techniques allow users to quickly access all parts of tabletop workspaces
without the need for physical access; however, indirect techniques restrict the available …

We describe a study that investigated how a shared interactive tabletop (DiamondTouch)
can be designed to provide new opportunities for supporting collaborative decision-making …

DiamondSpin is a toolkit for the efficient prototyping of and experimentation with multi-
person, concurrent interfaces for interactive shared displays. In this paper, we identify the …

The goal of our research is to support cooperative work performed by stakeholders sitting
around a table. To support such cooperation, various table-based systems with a shared …

Interactive tabletops have been previously proposed and studied in the domain of co-
located group applications. However, little fundamental research has been done to explore …

The Palette is a digital appliance designed for intuitive control of electronic slide shows.
Current interfaces demand too much of our attention to permit effective computer use in …

A digital tabletop offers several advantages over other groupware form factors for
collaborative applications. However, users of a tabletop system do not share a common …

With the availability of new input devices such as DiamondTouch [1], multiple users can now
interact with a 2D surface using both hands and/or multiple fingers simultaneously. From our …

We explore how the placement of control widgets (such as menus) affects collaboration and
usability for co-located tabletop groupware applications. We evaluated two design …
