Ask Slashdot: Calculators With 1-2-3 Number Pads?

dotancohen writes "Although the telephone has the 1-2-3 key on the top row, most calculators and keyboards have 7-8-9 on the top row. Switching between the two destroys muscle- and spatial- memory. Do any slashdotters use a scientific calculator with 1-2-3 on the top row? I've already scraped and resoldered my Casio fx-82 calculator to have 1-2-3 on the top, and remapped the numpad in Kubuntu, but if there exist any calculators like this already on the market, I'd buy two."

Don't you have anything better to do?

Seriously.

You have an interesting question there. I don't consciously imagine punching in a phone number, but as I do it my muscle memory helps me know when I've done it wrong. (Thanks for the link to Anki, also.) However, I almost never need to type in phone numbers on a computer, and it sounds like the only reason you do is so that you can use the memory aid tools. Do you do a lot of work with calculators? The way I type in numbers on a phone is normally with my thumbs, rather than my fingers, so it's (for me) a very different mental task than keying in on a keyboard. I don't think I'd have much overlap between the memory of typing numbers on my phone versus typing them on a keyboard.

A sibling commenter mentioned that they are terrible at remembering phone numbers. I am too -- that's why I use a tool to remember them for me. Why do you find yourself caring whether you have it in your head versus in the phone's memory?

Who memorizes phone numbers anymore? Twenty years ago, I probably knew 100 phone numbers, and now I know maybe 10. My phone knows the numbers of the people I call, not me.

The calculator layout is much more important in terms of spatial memory than the phone layout. Data entry operators and spreadsheet power users have been using the 10-key format for many decades. If you need to make a change, make it on the phone, not on the calculator.

Ask Slahdot: Calculators with Rotary Dial?

[makubesu]

Although the telephone has a rotary dial for dialing numbers, most calculators and keyboards have button pads. Switching between the two destroys muscle- and spatial- memory, as well as ability to use commas. Do any slashdoters use a scientific calculator with a rotary dial on it? I've already scraped and resoldered my Casio fx-9000 calculator to have a rotor, and plugged a USB rotor phone into Gentoo, but if there exists any calculators like this already on the market, I'd buy three.

Not true:

On a side note, back in my teens, I would make $5 for swapping the top and third rows of buttons on a standard WECO 25xx phone so that they matched an adding machine. The ladies in the office loved it.

OCD Much?

So if it "destroys muscle- and spatial- memory" as you say, that means that everytime you wanted to use your phone you would have to sit down in a chair, find a horizontal flat surface to lay your phone on and then dial with 3 fingers? Or do you do it the other way around? Everytime you want to use a numeric keypad on a keyboard you have to pick up the keyboard off the desk and double-thumb the numbers in? I have GOT to see this in action!
