How about some music, to start your day’s work out at the gym or while jogging? It is a fact that your favorite song tracks could make you smile. And if you have a nice pair of headphones plugged into your ears when you do your routine work outs, there is bound to be harmony that connects your body and mind.

For those who always bring a music buddy with them during their workout might also have some moments where they couldn’t enjoy their playlist because of their mood swings. And you will be pausing your drill to shuffle through the long list to get a right song for that time.

A group of researchers led by Shahriar Nirjon at the University of Virginia in Charlottesville thought of helping us with this juggling and that they have ended up developing an app prototype which will help your smartphone to choose the right music that gels well with your heartbeat.

They call it the MusicalHeart. Using headphones that can measure the heart beat and the acceleration of your body, the app grabs data from it and picks the good ones from the playlist so that you can maintain the predetermined target heart rate for getting the better work out.

You should also know it not only pumps up beats but also calms you down with slow songs if you’re sitting for a meditation, just turn the target heart rate to your desired level.

Right now, they have completed their initial prototype and will be showcasing at the 10th ACM Conference on Embedded Networked Sensing Systems at Toronto conducting next month. They have attained 75 to 85 percent in accuracy and an average error of 7.5 beats/min and got hit the spot with 90 percent of users reaching the target heart rate.

So if they are coming up with a market model very soon, be ready.
