Samsung's most recent update to S Health has an interesting new skill, the ability to tell if you're stressed or not.
The update uses the heart rate monitor function to detect variations in your heart rate over a period of time. The technique, known as Heart Rate Variability or HRV can detect stress levels my monitoring for sudden changes in your heart rate. If you're not working out, and your rate changes rapidly, then that's a sure sign you're stressed.
The detection is, apparently, reasonably reliable for general use, probably to the same extent as the heart rate monitor itself. That said, we do wonder if people who are stressed don't realise it. Usually when we're suffering from stress, we know all about it, what with all the stress, and all.
As with all the health monitoring functions, the app is able to track stress over time, as long as you take regular readings. Presumably the detction could also work with a smartwatch too, giving more constant data about your condition.
This is all an interesting part of Samsung's attitude to health at the moment. Some have mentioned that Apple will launch its own health monitoring platform at WWDC soon, and if that's true it might explain the push from Samsung. Even so, it seems that 2014 is going to be the year of mobile health.
