Abstract

A word predictive data entry system includes a plurality of first input signals to which one to a few characters are assigned, and an input signal, separate from the plurality of first input signals, to which a significantly larger number of characters are ambiguously assigned. The system uses a database of words wherein upon receiving a sequence of the input signals the system predicts one or more words from the database of words.

Claims

1. A data entry system, comprising:

a plurality of first input signals to which one to a few characters are assigned, and

an input signal, separate from said plurality of input signals, to which a significantly larger number of characters are ambiguously assigned; and

a word predictive system using a database of words;

wherein upon receiving a sequence of said input signals the system predicts one or more words from the database of words.

2. The system of claim 1, wherein each of said plurality of input signals ambiguously includes few characters.

3. The system of claim 1, wherein each of said input signals is provided by interacting with a separate key.

4. The system of the claim 1, wherein to each of said plurality of input signals up to three

characters are assigned.

5. The system of claim 1, wherein said plurality of input signals together represent a first group of letters of a language, and the separate input signal represents a group of letters that at least includes the remaining letters of the language.

6. The system of claim 1, wherein each of said plurality of input signals is provided by interacting with a separate key.

7. The system of claim 6, wherein said keys are divided into two groups.

8. The system of claim 6, wherein the separate input signal is provided by interacting with an additional key located between the two groups of keys.

9. The system of claim 6, wherein each of said separate keys represents one

character.

10. The system of claim 6, wherein each of said separate keys represents three characters.

11. The system of claim 6, wherein said separate keys are four keys.

12. The system of claim 6, wherein said keys are on-screen zones.
