We propose a new display table that allows multiple users to interact with both private and public information on a shared
display in a face-to-face co-located setting. With this table users can create, manage and share information intuitively,
strategically and cooperatively by naturally moving around the display. Users can interactively control private and public
information space seamlessly according to their spatial location and motion. It enables users to dynamically choose negotiation
partners, create cooperative relationships and strategically control the information they share and conceal. We see the proposed
system as especially suited for strategic cooperative tasks in which participants collaborate while attempting to increase
individual benefits, such as various trading floor-like and auction scenarios.
