Imagine running on the rocks of Kjeragbolten, Norway or the ruins of the Palatine in Rome or even outside your gym crush's house (kinda creepy). At CES 2011, Panasonic connected a Nordic treadmill to a monitor and the internet – the result was a run in semi-virtual reality. What's even more interesting is that even though you might be able to do this by sticking a tv and movie in front of your treadmill, the maps communicate with the treadmill to incline and decline at the appropriate spots on the hills you're running through. You haven't left your house, but you have enough visual and kinetic stimulation to feel like you have.
Check out this video that Mashable got of a demonstration of the hookup. I can't wait to place my order.
