FITALY is a keyboard layout specifically optimized for stylus or touch-based input. The design places the most common letters closest to the centre to minimize distance travelled while entering a word. The name, FITALY, is derived from the letters occupying the second row in the layout (like QWERTY comes from the 1st row of standard keyboards)
In the first of several keyboards in the system, lowercase letters are arranged in the following pattern:
| z | v | c | h | w | k |
| f | i | t | a | l | y |
| n | e | ||||
| g | d | o | r | s | b |
| q | j | u | m | p | x |
There are uppercase, numeric, and symbol keyboards as well, and various strokes (rather than taps) are used for both shifting case and selecting symbols. For details, see the manufacturer's site (below).
Fitaly was invented and patented by Jean Ichbiah and is commercialized by the company he founded, Textware Solutions.
The aim of the design is to optimize text entry by organizing keys to minimize key-to-key finger movement, allowing faster input through one-finger entry (compared to 10 fingers required to type efficiently on QWERTY layout). As compared to the 3-row QWERTY keyboard, FITALY has 5 rows with at most 6letters in a row (as against 10 on QWERTY).
Keys are arranged based on individual frequencies of letters in the English language, and the probability of transitions. The ten letters at the very center (i,t,a,l,n,e,d,o,r,s) are used 73% of the times when typing in English and with c,h,u,m added to the list, the number goes up to 84%. Keys are never more than 2 blocks away (vertically, horizontally or diagonally) from the current position. You nearly always find the next likely letter on a key very close to the one you just tapped.
