Near Future Electronic Game Controllers?

How far can you go with a game gesture? Can shopping at the Farmer's Market become an interface to an offline game, such that my action and activity while shopping powers-up my electronic game avatar while I'm away from it? Is our imagination open to the idea of gaming..even while not in front of a screen? Can you keep it in the back of your head that "stuff" in the online game world will be affected by your activities in the offline world? How will that change our perception of activities offline? How will it affect our attention to what's actually happening around us? What will it feel like to know you're gaming even though you're not twiddling keys on your mobile phone, nor looking at its little postage stamp screen? How about this — you're not even networked! Everything is stored up and then uploaded to the mothership later, when you're back home ready to be an online agent again. You get to participate in what's going on in 1st life, all the while knowing in the back of your head that your actions get to become something valuable in 2nd life!
