Or I guess you could do long-press to turn off or something if you're worried about confusing people, but I really don't think that should be necessary. We know how toggles work. The button lights up when it's on.
It works fine, but people's reaction on hearing this is always interesting, ranging from:
- enthusiasm: that's awesome everyone should do that
- skepticism: that seems like a terrible idea, people will un-press your floor and chaos will follow
- denial: you didn't see that
- cultural / racist: that would never work in <name your country> it must just be because Koreans are <random cultural conjecture>
I can see some engineers deciding that the button press needs 2FA or TOTP so only you can unpress it. Bonus points if you need to buy their brand's smartwatch to use it.
More examples:
This man has sixteen hundred videos of riding up and down elevators and is still going strong. Amazing. I love how Grandma was willing to ride random elevators and feature in his videos if it meant she could spend time with her eccentric grand son.
That's my point. The attack goes away if you can un-press buttons.
