If they are actually just using eye dilation for funny faces, I would be shocked. It's one of those things that's pretty telling physically. Whichever congressman asked that question was NOT dumb.

It would require the camera to be on without notifying you, which isn't possible on modern OSes. Also, changes in pupil size are caused by many different things. That question is similar to asking whether heart rate can be used as a signal. They're not tracking eye dialation for funny face filters. That level of tracking requires cameras better than phone selfie ones. "The responses can have a variety of causes, from an involuntary reflex reaction to exposure or inexposure to light—in low light conditions a dilated pupil lets more light into the eye—or it may indicate interest in the subject of attention or arousal, sexual stimulation,[3] uncertainty,[4] decision conflict,[5] errors,[6] physical activity[7] or increasing cognitive load[8] or demand." https://en.wikipedia.org/wiki/Pupillary_response https://en.wikipedia.org/wiki/Pupillary_response https://www.microsoft.com/en-us/research/wp-content/uploads/2017/01/everyday_eyetracking-1.pdf https://www.microsoft.com/en-us/research/wp-content/uploads/...

He absolutely was. He asks "Can you say with 100% certainty that TikTok does not use the phone's camera to determine whether the content that elicits a pupil dilation should be amplified by the alogorithm?" Chew: "The only face data that we collect is when you use the filters to have sunglasses on your face, we need to know where your eyes are." Congressman: "Why do you need to know where the eyes are if you're not seeing if they're dilated??" Apparently I can only find primary sources of this hearing on TikTok itself, so: https://www.tiktok.com/@jamiethisyoujeffries/video/7213878230615362858 https://www.tiktok.com/@jamiethisyoujeffries/video/721387823...

  And from the c-span youtube channel, timestamp ~2hr 14m 50s. https://youtu.be/_E-4jtTFsO4?t=8090 https://youtu.be/_E-4jtTFsO4?t=8090 You can click the three dot menu next to the share button to pull up the autogenerated transcript or offical CC on c-span, on youtube. I don't think you can search in the yt app like you can on desktop/mobile. The comments section there speaks volumes about the divide between those congressman and younger generations.
