I get splitting the keyboard in two. I don’t get why the letters are re-arranged from traditional keyboard. That part makes no sense.
Putting all the vowels, except ‘y’ on the right side along with the most used consonents on the left side gives a more ‘equal use’ or ‘ambidextrous feel’ to it.
There was a story in one of the ancient computer mags (Computer Shopper?) back in the 80’s about the origens of the ‘QWERTY’ keyboard layout.
It seems that the original typerwriters had a different letter layout than is now standard. But the typists of the day could type faster than the mechanics of the early typewriters could handle, getting keys jammed and slowing up productivity. So the engineers of the time came up with the QWERTY layout in order to effectively slow down the typists instead of making the typewriters faster! But that layout has been lost in history...........
