Google can turn ANC earbuds into a heart rate monitor with no extra hardware

"Everything we measure about you can and will be used against you."
Then there will truly be nowhere to hide.
The thing with the cryptic infection in Ohio was maybe personally invasive (but as far as I know, no PII has been revealed): https://www.darkdaily.com/?p=43174
Possibly something holding practical implementations back is all the other waste put into sewage, which may stop things up in the manner of “fatbergs.” [0]
A related idea I have percolating is to change municipal composting programs from bins and trucks to grind and pipe by deploying more sink fixtures that grind food materials into small pieces so they go thru the drain. Then focus extracting/separating biological materials from other effluvium.

On a slightly less dystopian note, I can't wait for the DefCon talk on spoofing anus prints
I'm hacking on a local-only, slurp-every-data-point-about-myself program, and I missed adding a analyzer for feces and urine! Thanks for sharing your sarcasm :)
Hmm. May I recommend switching to a less...abrasive fiber supplement? You might be able to relax your protocol a smidge if you do.
20+ years later, I live in Japan and they're nowhere to be found (thankfully)
Fifth generation warfare probably doesn't need a mostly useless and high noise-to-signal surveillance method like EEGs.
‘Dystopian’ is exactly the right word.
It might be a rhetorical question but do someone in the industry has any idea? It has some value, like most metrics but my suspicion is that it is relatively low.
It is a proxy for a secondary metric. The reason people put up ads is to drive up sales, so that's the important metric. A secondary metric is engagement it can be directly measured by click through, time watching, etc... And then you have heart rate, which may indicate an emotional response, but it can be anything else. For example I am pretty sure that on average the heart rate goes up when TV ads show, but it may just be because of the physical effort of standing up and walking to the bathroom. Which is probably more significant than the emotional response caused by ads most people are desensitized about.
It could be useful for A/B testing, with the heart rate metric being the average value of your overall data.
I wonder if you could also compare WHEN the heart rate increases with the timing of the ad - for example if your ad ends with a funny punchline and your logo, seeing the heart rate spike is a good sign people are laughing at it.

They are using the ANC speaker mic pair as the source of _acoustic_ information to infer HR from within the earbud.
As in there are no electrode pads or light sensors or some other known method for HR monitor.
...as in it has a microphone.
But yes the Google buds are Bluetooth and use separate microphones to send recorded audio back to the device for voice calls, etc.
I'm not aware of anyone doing that with a single electromagnet and 2 wires.
I don't know how far you could take it though. Irregular heartbeat in a resting patient, possibly. Clogged artery not in the measurement path in an active patient - probably not. The further from the heart the less and less it looks like an ABP blood pressure wave. I bet activities like jumping up and down would show some amount of interference from blood sloshing around in APG just like in PPG.
If you want to look at some data, https://physionet.org/ has some recordings of PPG and ABP and you can see how they differ. (Edit) like this one: https://physionet.org/content/mimic3wdb-matched/1.0/
Ultimate accessory for a sports watch would be to have earbuds that also monitor HRV and blood pressure which is pretty much garbage from the risk at high intensity.
I'm concerned that protracted probing may contribute to hearing loss.
