It is for those very short persons (e.g. small kids) who know simple algebra.
The press buttons to select destination floors are normally arranged in ascending order from bottom to top. If a short person wants to go to say 25th floor, it is very difficult for him/her to reach the corresponding buttton.
If small panel at lower height with three fields for data entry are provided, it will be very convenient for them. The configuration will be 'Field1' '+' Field2' -->'Enter'
e.g. to go to floor 25, enter '20' '+' '5' (or any other combination of numbers totalling 25) & press enter.
Alternatively, provide 2 similar panels separately at average height of short persons & tall persons for their corresponding use ;).

Some (but by no means all) elevators in NYC have one of their two sets of buttons set low, for short people and people confined to wheelchairs. Some few have straightforward numeric keypads for entering the floor. |
|
| |
Either approach beats algebra. |
|
| |
I think there should be a numeric keypad into which you enter the square root of the floor you wish to go to. |
|
| |
But consider the possible consquences of a missing digit, or a misplaced decimal point ..... |
|
| |
Floor 2034 is a scary place. |
|
| |
[Dr Curry] This idea is for those elevators where straightforward numeric pads are not there (I belong to a developing country). It will be expensive to replace all press buttons with such pads; modification involving algebra will be a cheaper solution. |
|
| |
I conceived this idea after observing my son facing the problem mentioned in original description. |
|
| |
Isn't there something about the decimal system that would end up sending a lot of people who are not good with numbers to the 9th floor? |
|
| |
[8th of 7], [Canuck]Why will the decimal system be required? Only to complicate the things through redundancy? |

vedarshi: I have an even simpler, cheaper solution for you then: a step stool. |

Forget the keypad. Just have a dial (with all the floors on it) and a button. This also makes it harder for a prankster to select every floor. |
|
| |
Forget the dial, too - just throw in a voice recognition thing, judging by the phone menu systems they seem to work quite well these days. It could also remember voices and cancel the previous request upon receiving a new one, thus solving the prankster problem. |

|
| |
So by providing stepped stool you mean to waste space & put extra load to consume more power on continuous basis !? |
|
| |
or an ever better solution for this fattening planet, |
|
| |
take a coathanger with you, and take the stairs (coat hanger if you cant reach the handle) |
