iPhone takes infrared photo of your face every 5 seconds

This is used for their attention feature that prevents the screen from locking if you're still paying attention to it.

Hopefully. I wonder if the infrared pictures will stop if you disable the setting. Also, I wonder what effect this will have on battery life.

This has been a feature since the iPhone X came out I believe, so the answer is: negligible.

Can't wait for the attention web API to show up in Chrome. Pretense: pause your video when you're not watching. Practice: can't get past the ads unless you are determined to be paying attention to them.

There has to be a better medium for this than some 1min long narrow video that stops playing when I switch tabs.

Regardless, does anyone have more information on what might be happening?

Linking to Tiktok should be banned on HN.

Does anyone know what they use this for? I don't want to be pessimistic and assume its all for tracking, but I feel like I'll be let down.

what would they gain, tracking wise, by taking pictures of your face? it's used for this: https://support.apple.com/en-us/HT208245
