The response I anticipate will be "But this will help doctors over telehealth and stuff!" - Please see https://calebhearth.com/dont-get-distracted
You see this type of thing in spy movies, but I'm not sure it's that useful in real life. You're basically taking one piece of data a polygraph uses, but without the most important component (skin conductance). Polygraph accuracy isn't that great to begin with. You can profile and manipulate people more effectively based on their reactions and behaviour, and their pulse will be much harder to interpret.
Can you cite any commercially available uses of such tech?
1. `/api/event` endpoint mentioned in the `/stats/script.js` file;
2. There's `/parties/lobby/main/telemetry` in a minified JavaScript chunk asset;
3. There's VitalLens mentioned, and there's an error string in the same asset: "A valid API key or proxy URL is required to use VitalLens. If you signed up recently, please try again in a minute to allow your API key to become active. Otherwise, head to https://www.rouast.com/api to get a free API key."
He even shows pulse detection (around 8:30).
At one point I added the same EVM based heart rate detection but that requires sitting very still. I use it on my phone mainly therefore the common finger method is easiest one to use.

``` try { const l=await navigator.mediaDevices.getUserMedia({audio:!1,video:{facingMode:"user"}}); /* ... */ } catch { this.showError("Could not access webcam. Please check permissions.") } ```
There are alternatives to verify mediaDevices support as https://addpipe.com/getusermedia-examples/
It's super cool. Thanks for sharing. I want to build a biofeedback app for meditation and this looks like a good platform to use.
It's still vague beyond saying they trained an AI: "VitalLens is trained on the PROSIT and Vital Videos Africa dataset...The time-synchronized sensor array used for PROSIT consists of a video camera, electrocardiogram (ECG), pulse oximetry, blood pressure monitor, and an ambient light sensor. "
