Heart Rate Belts, Phone Cameras and Convenience

I had a chance to have a coffee with Marco Altini, the builder of the Heart Rate Variability Logger app that I often use to take readings. I enjoyed the discussion as Marco is very knowledgeable on the topic of heart rate variability. I took some key insights away that will help me set direction for future studies.

During the discussion he told me he is focussing on his app that support physical training, HRV4Training. He prefers to work on this because in addition to a bluetooth heart rate belt the user can choose to take a reading with the camera on the phone. Marco thinks that the convenience of using the camera makes it more accessible.

I agree with him. In my own work I often to not take advantage of readings because I don’t have the belt on and simply don’t feel like putting it on. Just this week I did one reading while conducting an interview using the belt, and I did not take readings on numerous meetings that would have given me good data for further study.

And while pushing into new areas of study such as heart rate variability during negotiations, or while giving a speech, it is not going to work to have a finger on a smart phone camera. To only use the camera would confine readings to stationary sessions where no activity was allowed. There is much more to learn than taking readings in only a motionless state.

So I am going to start incorporating smart phone camera useage into my work and share the results here. Marco has done a workup of how his apps use the camera to compare well with the Polar H7. We have to figure out a way to make this accessible, and useful, so more people can train for improved personal performance using heart rate variability.
