I saw this in an elevator in India recently. The third-hand instructions we heard were that you double-click the button to cancel, so all of us computer nerds were trying to double-click it like you would a mouse, when apparently it's click-pause-click.

I've seen elevators that ignore short presses of buttons. You press the button, it lights up, you release, the light goes off and the elevator pretends it was never pressed. Any idea why this is being done?

I don't know why someone implemented it specifically, but I can think of 2 possible reasons: (1) To prevent accidental presses, and (2) prevent maliciously pressing every button quickly.

Or a third option: it's just shoddy implementation that happens to have an annoying effect.

Could also be a debounce mechanism to cancel out multiple presses too close together which is just a reality on switches even if you physically only pressed it once.

If you're turning in a crammed elevator you could be momentarily pressing multiple buttons with your backpack. That would most definitely be annoying for everyone.

Did you merge two comments together?

oh shit I did. I doubt elevators run KDE or have dual core processors lol

If they don’t already I wouldn’t doubt it happening in a few years…
