Understanding designer brainstorms: the effect of analog and digital interfaces on dominance.

Brainstorming has long been an integral part of the design process. However, only recently have technological advances given rise to collaborative interfaces for facilitating brainstorming activities. While there has been some research on the effects of these technologies on group dynamics, little is known about how collaborative interfaces affect dominance within a brainstorm in interaction design. In this paper, we explore the relationship between one collaborative technology, the DiamondTouch Tabletop, and dominance in designer brainstorms.
