First Claim
1. An alphanumeric data input system comprising a 3×
- 4 alphanumeric keypad of keys, a display, and a program controlling the operation of these components, the keys representing digits from “
0”
to “
9” and
“
*” and
“
#”
signs respectively and the keys for digits from “
2”
to “
9”
also representing the letters of alphabet sequentially in respective groups of three to four letters, wherein at least one of the keys upon pressing will cause the display to display the letters of the associated group in both lowercase and uppercase and the associated number together in the form of a grid of locations corresponding in position to the keys of the keypad, and subsequent pressing of one of the keys corresponding to the location at which a desired character is displayed will result in input of that character, thereby allowing any sequence of characters to be inputted.

Abstract
An alphanumeric data input system, and related method, comprising a 3×4 alphanumeric keypad of keys, a display, and a program controlling the operation of these components. The keys represent digits from “0” to “9” and “*” and “#” signs respectively and the keys for digits from “2” to “9” also represent the letters of alphabet sequentially in respective groups of three to four letters. At least one of the keys upon pressing will cause the display to display the letters of the associated group in both lowercase and uppercase and the associated number together in the form of a grid of locations corresponding in position to the keys of the keypad. Subsequent pressing of one of the keys corresponding to the location at which a desired character is displayed will result in input of that character. Pressing of the keys representing the initial string of a word will enable matching through the database for a word sharing the same initial string and then displaying of the word in its root form on the display. Subsequent pressing of one or more of the keys representing a respective suffix available from the database will result in addition of the suffix to the root word and thus input of the complete word.
