Those are most likely modules using wafer level optics: https://ams.com/cmos-micro-camera-module

NanEyeC is 1mm by 1mm, with 320 x 320 resolution. Unbelievable. And slightly worrying: it totally breaks my expectation of what can contain a camera.

Can't wait for these to be embedded in "smart" TVs for gaze tracking during ads.

TVs are massive, so they don't have to be this small and you can already buy TVs with built in cameras, since it can be used for video conferencing. Also, this type of tech can already be used to measure ad awareness in stores [0]. It's also starting to be implemented in cars, to check whether you're paying attention to the road while using 'autonomous' systems.

So... This is not really a type of tech that will enable your fears, it already exists, there just doesn't seem a business model for applying it in TVs yet.

Those tendrils are cameras?! What the hell?

In each lens, 2 are cameras (inner bottom), other 8 are IR illuminators.

Ah okay, that makes more sense, thank you.
