I tried this out for the past hour or so. It takes the 9 most common letters in English and makes them easily accessible through one touch down, whereas all the other letters require a touch+swipe.
Multi-lingual support is problematic, the 9 most common letters differ per language, even if you stick to those based on a latin script. So either you end up learning multiple layouts for multiple languages, or end up doing way more touchswipes than should strictly be necessary.
Granted, I am a pretty fast and accurate two-thumb typer on a qwerty keyboard (AnySoftKeyboard) on my phone, so it might not be for me. Perhaps someone who struggles more with accurately hitting individuals keys would benefit more from this simplified keyboard
Point is, I doubt this system will ever be faster (for me) than typing on the qwerty keyboard where all keys are available at a single touch.
I would also be interested if this method would improve my ability to type blind, but I think it still suffers from the lack of tactile feedback there, I still dont know where my finger is exactly.
