How do you design an interface for a 1000 floors elevator?
Background and assumptions
I am assuming, that if we are trying to solve this problem it is possible and justifiable to build so high building thus we are in the future, far future.
The planet is overcrowded we need a lot of space for humans, additionally, we want to preserve as much nature as we can, that is why we build high buildings. Our civilization is technologically advanced and nature conscious. I assume, that because of the technological advance some of the solutions and concerns (privacy) that we have today are a norm in the future.
So high building, probably is a city itself, with all the main city infrastructure: offices, hotels, flats, shops, gyms, parks, kinder gardens, and schools.
For a reference point, I will use Burj Khalifa because it is the highest building we have so far. Burj Khalifa has 163 floors and around 4680 visitors daily. So our building should have around 30 000 visitors.
The visitors are: employees that use facilities of this building (offices, hotels, etc), tenants of the flats, building’s staff members, clients of the enterprises that are in the building and just visitors (clients of the clients, tourists, etc.)
With so huge amount of building’s visitors, I would assume that there are super users, that have some priority card (VIP).
I would also assume that the building has multiple entrances and halls with elevators. In my case, I will focus only on one hall with around 10 elevators.
I will focus on the design for offices workers and VIP users
1. Voice Control - the person who takes the elevator would say the floor’s number.
2. The phone (smartwatch, any relevant piece of technology valid for this period of time) control
User may use her/his phone to call the elevator by choosing the floor’s number. That way, the elevator's computer system, may choose the best elevator for every user, depending on where the user is, where these elevators go and where the user wants to go. When the user chooses the floor, the elevator number which was selected by the elevator system is displayed.
The elevator number that is on the phone's screen may change, depending on the demand and elevator system’s efficiency.
The building is completely integrated and stores the data of the visitors. Uses facial recognition, the data of visitors and their schedules, so that the computer system can automatically call the elevator and choose the floor number on behalf of the visitor. The computer system just sends the elevator's number to the visitor. The visitor doesn't choose the floor anymore.
For VIP users, the system tracks their position and calculates where the elevator should be sent that they would wait as little time as possible, and serves them at the first place.
