Train in virtual worlds with heart rate and play video game with your Xiaomi MI band 4, MI 3 or MI 2

Smartbands are small devices worn on the wrist which help you track your activities and improve your fitness level. Xiaomi is one of the main wristband manufacturers in the world and their devices brodcast heart rate in real time from which our app Arcade Fitness can compute power and speed. So why not using this information on a bike trainer or treadmill. They have several models such as MI 2, MI 3, MI 4

About our heart rate to power matching algorithm

We did a lot of research and simulations in order to find a good relationship between heart rate and power output. Power is very usefull for training indoor both for cycling and running but our app is not limited to these activities... You can use it as well on every aerobic training equipment such as a stepper, a rowing machine...

Heart rate is a good indicator for indoor training but power is much better. If you only look at heart rate, it can take up to several minutes to go from one intensity zone to another whereas power is much more reactive (between 10s and 30s). This allows a more precise training and increases the interactivity within the video game.

Here is an example which shows our results when we simulate power derived from heart rate:


Estimate power output from heart rate monitor


Please note that we took an example with the Xiaomi MI Band but any standard Bluetooth Smart heart rate monitor can be used as well together with Arcade Fitness video game. The HR sensor alone is enough, no other sensor needed!
