ABSTRACT
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 studies of groupware use as well as our own observations of groups using a shared tabletop display suggest potential for improving groupware interfaces by incorporating <i>coordination policies</i> - direct manipulation mechanisms for avoiding and resolving conflicts. We discuss our observations of group tabletop usage and present our coordination framework. We conclude with example usage scenarios and discuss future research suggested by this framework.

Recommendations
Exploring the effects of group size and table size on interactions with tabletop shared-display groupware
CSCW '04: Proceedings of the 2004 ACM conference on Computer supported cooperative workInteractive 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 issue of size. In this paper we identify a number of size considerations ...
An exploratory study of facilitation in distributed requirements engineering
There is an increasing need to build an understanding of group facilitation in distributed requirements engineering. Group facilitation is an important element of group approaches to requirements engineering, which is being challenged by the emergence ...
Release, relocate, reorient, resize: fluid techniques for document sharing on multi-user interactive tables
CHI EA '04: CHI '04 Extended Abstracts on Human Factors in Computing SystemsGroup 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 tabletop direct-manipulation interaction techniques that can be used ...
