Digital Pick and Drop concept

I'm finally back at the helm of the reloade journal, been away for a few months working on a uni research project. I came across this interesting article today on the BBC technology website about the development of Pick-and-Drop, which Sony CSL Japan have been working on since 1997. I found the whole concept quite interesting and also the two related research papers (PDF1, PDF2) by Jun Rekimoto, Director of the Interaction Laboratory at Sony Computer Science Laboratories, Inc.
