We've got to say, we're guessing both Survivor and Prince would approve here, as this is easily one of the most impressive uses of a heart rate sensor yet. Anaid Gomez Ortigoza, a bright young lad at NYU, has whipped up what he's calling kokoro, which translates into "the heart of things" in Japanese. Put as simply aspossible, this prototype project allows for iPod playlists to be shuffled depending on one's current heart rate; if your heart is pumping some kind of fierce, the device will likely cue up a little M83, and if you're at rest, you just might get to hear a smooth jam from the likes of Copeland. Don't believe us, though -- hop on past the break for a demonstrative video.
