- Some new phones (and laptops) have the ability to detect an authorized user’s face and unlock the phone without requiring a PIN.
- Often, if you have something stuck in your teeth, people won’t say anything. Then, hours later, you realize that you had, say, a huge leaf of lettuce in your hair the whole time, forcing you to re-contextualize all your social interactions since lunch.
Surprisingly, although the capability certainly exists, no face unlock system currently informs users if they have, for example:
- Something stuck in their teeth
- A weird thing in their hair
- Bizarrely smudged Joker-esque lipstick
- A bird that has made a nest in the user’s hair
Figures 1 and 2 demonstrate how the “face unlock” feature could serve the dual purpose of notifying users of such situations.
Since the phone already has the hardware to perform this public service, it would be a trivial addition to the standard face-unlock system. Note to Apple: you should pay me to license this incredible technology.
PROS: Gives the phone’s developer a leg up over competitors without robust lettuce-detection algorithms. It’s basically a free feature!
CONS: People might rely on the phone too much for even the most basic tasks, and civilization might revert to a barbaric age of inhuman savagery if there is ever a prolonged electrical outage.
