No matter. See my previous post.

Really, no matter what layout is used on a standard keyboard - it's easy to switch betweem them if you want type faster, if it's not an international keyboard layout - there are the standards of localization only for QWERTY - the US keyboard layout.

The implementation of international standards is the goal of my project as well as to make a mobile keyboard functional and comfortable for typing and that requires the same system of typing and ergonomic characterictics as of a standard computer keyboard.

The spaces between keys with letters actually are about the same horizontally - 7 mm - a whole column of keys - and switching between the two adjacent keys vertically is also comfortable for fingers when the distance between keys-sensors is 15 mm - this provides the contact area of 12x12 mm for them - 12mm is the width of the horizontal surface of the key of the standard keyboard. That's while the main part of 53 keys in a cell computer is 47X59 mm - four-five times more compact.

Then maybe there is a way to change key annotation dynamically? For example by coating the keyboard with some kind of elastic display (like iPaper stuff). This way you could even reduce the number of keys just by adding a "letter/symbol" modifier.

Two actions, anyway - that doubles the work. I've seen similar projects in the news. It's just a GUI, nothing new.

The fact is why a standard QWERTY keyboard works is in its hexagonal structure - the keys are in the right places where the fingers are moving (it's like when you untighten the fist - the fingers are moving like rays - four fingers for ten-finger method - three fingers - three standard keys - the width of them is 54 mm - in a cell computer). The rectangular arrangement of the keys is worth only for entering numbers as in a standard computer keyboard's numeric keypad or phone numeric keypad. All the existing implementations of mobile keyboards have *straight lines* of keys - so there is no any signs of the system of typing - just by one finger or by two thumbs. So it's tiresome for more than five minutes of continious work. It's like that all these mini and reduced copies of a standard keyboard are produced just by inertion - for 10 years, at least - only by wishes that sometimes it will work like its original, or at least half of its productivity. No magics. Hexagonal arrangement is the key. Like in 1874 in a Remington typewriter (http://home.earthlink.net/~dcrehr/firsttw.html).

"It is possible to touch-type even though the keyboard is very small."
