Abstract:
1. An apparatus for inputting letters of a natural alphabetic language having a first array of a plurality of keys having a first layout of a plurality of letters from a natural language assigned to various of said keys with at least one of said keys having more than one of said letters thereon, said first array and said first layout being row-similar to a second apparatus having a second array of a plurality of keys and a second layout, said second layout being that of a standard telephone keypad for said natural language, and where a given layout will be said to be row similar to a standard layout if a base-letter label assigned to a key in a row of said standard layout is also assigned to the corresponding row in said given layout, and vice versa, so that both said row of said standard layout and said corresponding row of said given layout have the same said base-letter labels and thus the same integer number n of said base-letter labels, but said base-letter labels are partitioned across said keys in said row of said standard layout and said corresponding row of said given layout differently, such that if said integer number n of said labels in said row of said standard layout are distributed across said keys in said row according to a partition P 1 of said integer number n, then said corresponding row of said given layout has said base-letter labels partitioned across said keys of said corresponding row according to a partition P 2 of said integer n, where said partition P 1 is not identical to said partition P 2 .
