You know what would be really cool? A #quantifiedself person influence monitor. Say I have a #Fitbit and Joe has a Fitbit, we could have them detect when we are in proximity (if both people agreed) and then it would let us know over time how being around the other person influenced us - e.g. did heart rate variability increase or decrease (do they relax us or cause stress), did we burn more calories (maybe we usually go on hikes together), did we sleep better that night, and so on.
There are definitely people in my life who I'm pretty sure have significant effects on me in both directions, it'd be awesome to quantify them.
It would also be cool if one could do this without data sharing - e.g. maybe one presses a button on ones device to indicate one has entered x's presence and again when one has exited...
Honestly, I'd totally forget to do this...so something passive would be better - e.g. when you want to start tracking the next time you are around someone you press a button and it scans for electronic signatures and identifies Bluetooth etc. uniquely so that when you are around then it auto knows and can record...
The latter raises issues of #consent and #privacy...I'm not sure how/if one could do this in an ethical manner...but I'd like to have it
