Elevator control panels

Here is an interesting piece of work about elevators by John J. BARTHOLDI, III. Designers of user interfaces: The elevator industry needs you! Behold the evidence.

As an untrained user of elevators, it seems to me that you want three basic things from an elevator control panel:

- Tell me what my choices are.
- Allow me to signal my choice.
- Confirm my choice by some feedback so I will not fret.
Is that so hard?

Click and enjoy the elevator control panels... ;)
