Mobile Phone Keyboard Redesign
A normal keyboard way designed to be typed with both hands, ten fingers.
A mobile phone Keyboard was just a copy.
Using Fitts law, I think the mobile phone keyboard should be redesigned for one or two fingers. The keyboard would be circular, with the most used keys towards the center. Just like a normal keyboard's most used keys are the home keys.
Would this increase speed and efficiency for user?
Would this be a bad idea for a mobile phone company to come out with this?
