A lot of people wear smart watches and other fitness trackers these days. All of which measure at least the wearers pulse, usually a lot more data – even automatically recognizing type of exercise. Some claim to analyze stress levels directly.
The measured data is usually stored on servers of the manufacturer and does provide a large amount of data about individuals across regions, even whole countries.
I know that analysis of data like this is common practice in other fields. However, I’m unsure if the available data from the fitness trackers could provide clear enough pattern for any usable results.
Data access issues aside, to examine the concept of the idea, can the pulse histogram data (for example, of a large amount of people) be used to identify stress and anxiety changes – possibly correlated with events in the given region to analyze their impact?
