Serious developers are using this for therapy. Imagine a virtual doctor who can see your real smile when you tell a good memory. It’s surprisingly human.
Other creators are making horror games where a monster mimics your exact facial expression. You smile, it smiles. That’s terrifying and genius.
And for the lazy: you can set your avatar to "permanent smirk" mode. It’s a button. You don’t even have to move a single cheek muscle. Cheater.
Bottom line? The Quest 3S face tracking turns you into a digital actor. You’ll laugh, you’ll look silly, and you’ll never want to go back to dead-eyed avatars. Go ahead, make a silly face at the future. It will make one right back.
