B16x2 Keyboard has found out the optimum to human hand structure for mobile typing. It is comprised of [16 key + 32 key]. If you are familiar with 16 key, you can naturally do with 32 key.

See-letter typing(typing seeing the letters being typed instead of seeing keyboard) will be naturally possible in the future when there has appeared the haptic tech to sense key location with only fingers.

Even now, it is possible with 16 key. The see-letter typing itself has its own irresistible attractions, fascinating many people.

If you want to try it, the most important is to (1)find and keep optimum button size for your fingers and (2)fix the location of both hands holding the phone, on basis of which you can sense the location of each key. The goal is to naturally type seeing letters but not never-see-Keyboard. Therefore you need to (3)refresh your sense of each key by seeing keyboard at start or whenever fingers are tired and dull.

If the conditions are satisfied, you can more and more exactly strike the key, but if not, you are building the house of cards.

The average standard button size is 62×58 on basis of Galaxy phone. You can set exact size or x y margin at Tutor and take them from Tutor to keyboard. As for some persons, plugged-in cable can be helpful to fix both hands.

With 32 key, it is much more useful to work with a word prediction like "B16x2 English Prediction".

From this you can see the future keyboard you can type fast in a consistent way anywhere from mobile to desktop.
