Ryan Challinor (I think he is from MIT) hacked his wrist watch with heart rate monitor to control the tempo of artist Carly Rae’s hit song Call Me Maybe played on an music player. The higher his heart beat rate gets the higher the tempo of the song goes. I think the usual tempo of the song when played unaltered is 135. Now that is clever! 😀
Now I am thinking of what other cool applications of a his hack could there be. What about automatically choosing the genre of the songs being played on your music player based on your heart beat rate while you are running? Hmmm..coolness! ~_<
