Kokoro music player concept will match tunes to your heartbeat

The Kokoro music player concept seems to be a take on the Yamaha BODiBEAT. Just like the BODiBEAT plays tunes according to your pace, the Kokoro plays tunes according to your moods (or technically your heart beats). The ‘kokoro’ wearable playlist generator comes with a Polar heart rate sensor which transmits that data to an iPod, where it will then select tunes from your existing music library to match the current heart rate. Just like any other player you are required to program it and set different tunes to match your different emotional levels. For example, our heartbeat is slow when we’re relaxed, while whenever we’re stressed or involved in a high intensity workout, our heartbeat rate increases by more than double. So, by sensing your heart rate this player will play different tunes to match your moods.
