Last November 13 I came up with a phone keyboard layout (strategy) that can make key size bigger hence less mistyping.
The typical phone keyboard looks like this:
My proposed keyboard looks like this:
Essentially, it's a split keyboard with the left-hand part stacked above/below the right-hand part. Key size/width/height and the vertical distance between the left-hand part and right-hand part may be adjustable to suit different phone widths and user hand sizes.
You guys can show the proposed keyboard's image on your phone and fit this keyboard to your phone width so you can actually simulate typing on it to see how it feels. On my phone, the letter keys in it are a little too big for my thumbs to reach the farthest keys, but as I said, key size should be adjustable to suit different phone widths and user hand sizes.
