For all my students and anyone else who is studying or practicing IxD and wondering where to look to see GREAT IxD research. THIS is gold! This utterly the best presentation of the behaviors of interacting using Near Field Communications (NFC) technologies.
The folks at the Oslo School of Architecture & Design (AHO), Touch project (http://nearfield.org) have always presented great work (Take a look at their archives). But this piece in particular is the perfect combination of IxD theory, material execution, and theoretical visualization all in one video.
Kudos to @timoarnall and the folks at BERG.
Take a look at the video here:
