I recently built a prototype of this style of keyboard for Android for Latin and Cyrillic alphabets because of how frustrated I am with any form of input that involves dictionaries, guesswork, and tiny buttons. I then used it for half a day. It works, I can type words on it, but at least for as much time as I used it, it was slower for me than Gboard because I had to make a mental effort to remember which gesture from which button types which letter. Typos were almost nonexistent though. Now, I arranged the letters very naively, I simply took the T9 layout and adapted it for these directional swipes. It might work better if I arrange letters by frequency. For example, such that typing the most common letters would always only require a tap, the less common ones would be a swipe down (which is easier for me than other directions), and so on. Here's a thread about it at the time: https://twitter.com/grishka11/status/1517431598857302019 https://twitter.com/grishka11/status/1517431598857302019
