A Lightweight Metaphor for Fast Object Transfer on Interactive Surfaces

What is a Dynamic Portal?

A Dynamic Portal is a lightweight interaction technique that allows users to exchange objects while preserving their spatial arrangement. Furthermore, objects are inherently aligned to the recipient’s workspace. Our technique involves a low interaction overhead, making it suitable for frequent use on tabletops. Additional the portals can be used as zoomable viewport and shared workspace.

Dynamic Portals are published at ITS 2011 where we received the award for the best note at this conference.
