• All those tasks need efficient and
extended character set!
(not only letters and numbers)
• How long it takes YOU to find and
enter most common signs like:
@ & / „” . – $ % (or even ; ! ?)
• Or whole expressions like:

methods in use
• T9
predictive (imperfect), dictionary based,
efficient only for standard words
• Multi-tap
any letter-number string, low-efficient
+ Special Signs ( , . ! @ ] ;-> )
Additional Input Methods

Today's 12-keys methods problems
T9 Multi-tap
• incorrect predictions • timeout / next button
(ex 729 can mean: SAY, SAW, PAY, RAY, RAW, etc
or 2273 : CASE,CARD,CARE,BASE,ACRE, etc)
• low efficiency
(more than 2
• words missing in the dictionary
(more efforts to add them/what if you use 2 phones?) clicks/character)
• International names, companies?
• names of places, streets?
• slang, creative words, misspellings?
•AllSentencesCombinedInOneLongW
ords?
Both R poor in entering special signs!

Main 1-2-b IDEA? (AKA anti-two-key)
x
 9 x 4 != 4 x 9 (!= means not equal)
Instead of using 9 groups of 3-4 letters in each
1 x 2
let’s use 3-4 groups of 9 letters
 --- => |
L R
Instead of using horizontal arrangement of
letter groups let’s use vertical so left finger
cooperates with keys 1,4,7,* and right with
the others
 use virtual keyboard
So you don’t need to remember all
combinations because you get online hints
and you don’t hide symbols under your finger!

„For me that makes no difference!”
• Arrangement in Old Two-Key:
abc def ghi jkl mno pqrs tuv wxyz
• Arrangement in 1-2-b:
abc def ghi jkl mno pqr stu vwx yz
• So, what difference does it make?
1a) Left Hand is responsible for groups
(and 3 letters in each group)
1b) Right Hand is responsible for 6 letters
/group
2) Simplification of group arrangement
implies NEW possibilities!

Possibilities!
Group
Menu „Repeat last item”/ „Hold group” button
Thanks to that button you don’t have to choose group
Item
Menu all over again and you can write „salaattijuusto” more
easily
rearrange special signs in rational groups
