Can this technology eventually detect their heartbeat, or is it just looking at slower changes over time? If the latter it sounds much simpler to defeat, if the former that would have many repercussions.
Live heart rate by video analysis would make things like televised court proceedings, congressional hearings, and news interviews much more invasive. Elevated heart rate is a sign of stress, and it wouldn't be long before people were jumping to conclusions over whether someone was lying or hiding their true feelings/intentions.

- dahdum 4y agoVery cool, thank you. I'm honestly surprised this dark magic hasn't been (ab)used yet, unless it has some strong limitations.
- bornfreddy 4y agoThis was quite a big news ~10 years ago... I think there are some patents involved, which makes the use of this technique difficult.
- ehsankia 4y agoNot sure if it's quite the same, but Google Fit has a feature that gets your respiratory rate from the selfie camera. They also have one where you put your finger on the camera flash and it uses that to see your bloodflow. https://www.lifewire.com/measure-respiratory-and-heart-rates-with-google-fit-5176887 https://www.lifewire.com/measure-respiratory-and-heart-rates...
- anigbrowl 4y agoCorrect, although those conclusions will be no more useful than existing ones based on facial expressions or lawyers' theatrics. The legal process can be just as stressful for an innocent defendant as a guilty/liable one, arguably more so.
