So why is it that if you select 2 and 3 you don't get to floor 5?

#22Might be a bit off-topic… But: The one big question I have with elevator UX is this: why isn’t it possible to deselect a choice? So pressed 10th floor but wanted 11th. There is no way to press button 10 and then button 11 to correct that mistake. Will I ever solve this mystery?
Because in a busy environment (where consistently more than one person uses the elevator) the scenario of making a wrong decision and having the wish to correct it occurs far less than the scenario where someone does not pay attention to which floors have been selected already and deselects your destination. At the worst case this means that you both miss your stop because you both did not notice.
Yes, some elevator environments are busy. But many aren't.

Yes of course it’s by design. I just wonder why.
Not worth complicating the UX to address such a minor issue.
Minor to you... Introducing a great experience is the job of good UX. Not simply limiting options and saying 'done'. I am sure there are better options to handle this. Seems like no-one has put the effort into it (yet).

Might also get confusing if the LED indicating the button's been pressed stops working
Re: Where to wait for an elevator (2010)
#26clearly they aren't using "destination dispatch" where the elevator tells you where to wait after you tell it where you want to go. https://en.wikipedia.org/wiki/Destination_dispatch I've only seen this in one building. It was a little weird, but it supposedly is coming soon to more and more elevators.
I live in a building that has this. As a resident - it works. Whoever made this building made a whole lot of mistakes though: - They put this into a building with public spaces (e.g. a doctor's office). - When standing in front of the elevators, nowhere does it say which office is on which floor (it says so in the lobby which you walked by to get to the elevators) - The screens where riders have to select floors auto…
I wonder if there is any improving that system without replacing it.

There are two cases where deselecting a floor would complicate the logic:
1. When the currently targeted floor is deselected and the remaining selected floors are all in the other direction: Then the elevator would have to either reverse course without stopping — a situation which otherwise doesn’t occur and would be unexpected and possibly dangerous for the passengers — or stop on a non-selected floor before changing direction, which would be confusing as well.
2. The deselected floor was the only selected floor: The elevator would then have to choose a floor to stop on by itself — e.g. the next one it can safely stop on — which is also a situation that doesn’t otherwise occur. In addition, deselecting the only selected floor doesn’t seem to be a practical use case.
So instead of having to define, implement and test a behavior for those odd situations, it’s safer and less costly to just disallow deselection.

If I were to guess, people enter the elevator and subconsciously just press which floor they want to go to. If you allow deselecting, someone will inadvertently deselect where they want to go to if that button is already selected.

#30> So standing in front of the second elevator minimizes the expected distance to the next elevator, assuming all three elevators are equally likely to arrive next.
> What if you want to minimize the worst case instead of the average case? Stand half way between the first and third elevators.
What is the difference between "in front of second" and "halfway between first and third"?
