While in the Royal Albert Hall in London yesterday I spotted an unusual arrangement of button-pressing options on the elevator control panel, along with an accompanying explanatory note.
Click on either image to enlarge it.
Despite the shadowy photograph it should be possible to see a column of numbers on the right with four at the top, counting down to G (ground) and B (basement). Slightly to the left of this is a separate number-entry keypad which has been slotted onto the main control panel – this extra set of numbers lets users keep the doors open (see instructions below) whereas the numbers and letters on the right determine to which floor the lift is being sent.
The photos aren’t very high quality I’m afraid, a consequence of a short lift journey and an old phone, but colleagues on CHI+MED collect examples of unusual number entry systems so I’m happy to share these.
