I'd love that kind of option to add to analog input, you know? Like a camera, or maybe 3D cameras soon, watching our faces and letting us use shortcuts or do things based on them. Squinting to zoom in, wide eyes to zoom out, a left blink for one thing, a right blink for another—head tilts and combos could work like our normal face stuff when we talk. Even a parrot's head tilt, eyebrow squint, and direct stare could be used—imagine answering "Are you for real?" with that! Endless options with AI learning—just look at your phone, make a face, and hit send!
