Apple recently released an operating system update for the iPhone. iOS 26 introduces facial control: you can scroll through videos with a tongue flick, like a video with a kiss, and more.
You can also link your face movements to turning the flashlight on and off, launching apps, and making phone calls.
To enable, go to Settings > Accessibility > Head Tracking (on) > Tongue Stick. Then, assign the desired function to this gesture.
So this is what you look like, the pinnacle of technological progress...
