Seems like Helsinki's always got something interesting to show
in its Nokia Research Center (NRC). Today's conceptual adventure
involves radar, or RADAR (RAdio Detection And Ranging) if you
prefer. Without going into too much technical detail, Nokia
demonstrates a handset that uses electromagnetic waves to
measure the speed of an impressively stoic Finn as he walks
towards and away from a prototype handset that can identify the
direction of movement. It also works through fabric to help turn
typically mundane tasks such as volume adjustment into an
aerobic art form. No really, see for yourselves in the video
after the break.   Nokia's mobile radar handset responds to
movement, not emotion (video)
