This article reviews the research and evidence about multi-touch tables to provide an
analysis of their key design features and capabilities and how these might relate to their use …

A Stanford University research group explores how design alternatives for tabletop
interfaces can impact group dynamics to promote effective teamwork. They built and …

Designing collaborative interfaces for tabletops remains difficult because we do not fully
understand how groups coordinate their actions when working collaboratively over tables …

A novel touch screen technology is presented. TouchLight uses simple image processing
techniques to combine the output of two video cameras placed behind a semi-transparent …

Multi-user, touch-sensing input devices create opportunities for the use of cooperative
gestures--multi-user gestural interactions for single display groupware. Cooperative …

In this paper we describe our findings from a field study that was conducted at the
Vancouver Aquarium to investigate how visitors interact with a large interactive table exhibit …

The status quo for co-located groupware is to assume that" social protocols"(standards of
polite behavior) are sufficient to coordinate the actions of a group of users; however, prior …

We have recently begun to see hardware support for the tabletop user interface, offering a
number of new ways for humans to interact with computers. Tabletops offer great potential …

Previous research has shown that rotation and orientation of items plays three major roles
during collaboration: comprehension, coordination and communication. Based on these …

This work presents the results of a comparative study in which we investigate the ways
manipulation of physical versus digital media are fundamentally different from one another …
