Interaction techniques for hybrid piles of documents on interactive tabletops

Piling is a highly common activity for the casual organization of documents. Today's tabletops do not offer sufficient support for piling, particularly in hybrid set-tings where both digital documents and paper documents are used on the same surface. We contribute several techniques for interacting with hybrid piles of printed and digital documents on tabletops. By employing a soap bubble metaphor and by using paper as a tangible control for the hybrid pile, these allow easy creating and rearranging piles while maintaining the flexibility of traditional paper piles.
