Keypad Research

Just some tab cleanup!

Phone dialers are a fascinating part of our lives. I remember moving from rotary dialers to a keypad and it was amazing. It was so much faster and easier on the hand! But the real game changer was the way it engaged muscle memory. (This is all fading as contact lists make remembering or even dealing numbers increasingly less necessary.) Most of us only experienced rotary or dialpad so it may not be clear just how designed the dialpad is. But Bell Labs experimented with a ton of layouts:

And Sajid Saiyed is revisiting this design space today! Dialing on a touch screen with a hand held, modern smartphone is very thumb oriented, but screen sizes make the pads less thumb friendly esp with the “dial” button pushing everything up a row. You can participate in the study (which looks for issues across demographics groups, which is interesting…I didn’t see across tab on screen size, though) using an iPhone app.

The current leading concept is very simple and obvious…move the seldom uses buttons (* and #) up top and slot the call button beside the 0. This brings every thing down¬†and makes the call button easier to hit. Neat!
