Micky at Nokia Users reckons this is one of the coolest things he saw at Nokia World 2010.
It’s a piece of indoor navigation technology, used to show the way around the conference’s array of cool stands – and also to track people and devices in the hall.
So how will this technology manifest itself in the wider world?
We’re hoping it will eventually spell the end of searching massive supermarkets far and wide for obscure ingredients for hours. The less time spent in those places the better!
What do you think this technology could be used for?
