Abstract

A data entry system using a number of different input signals provided by interacting with input means such as keys wherein to at least some of the different input signals a number of symbols including substantially all of the letters of the alphabet of one language are distributively assigned such that at least two of the letters are ambiguously assigned to at least one of the some input signals. The data entry system includes a database of words and uses a word predictive system such that in order to enter a word of the database the user provides a first input information consisting of providing the input signals corresponding to the characters, generally the letters, of the word, and an additional input information corresponding to at least one of the characters of the word and its corresponding input signal provided through the first input information, and wherein the system precisely recognizes the character among the ambiguous characters assigned to the input signal and provides a word of the dictionary that corresponds to the first and the additional input information.

Claims

1. A data entry system comprising:

a first input means for providing a first input signal that ambiguously corresponds to a plurality of characters; and

a second input means for providing a second input signal that unambiguously identifies an individual character;

a dictionary database; and

a word prediction system to provide word prediction from the dictionary database based on a combination of the first input signal and the second input signal, said characters comprising letters, numbers or symbols.

2. The system according to claim 1, wherein a first input signal is provided by a key interaction.

3. The system according to claim 1, wherein a second input signal is identified by at least one of a voice recognition system, a finger recognition system, and a swiping recognition system.

4. The system according to claim 1, wherein said at least one of the first input signals are the input signals corresponding to some characters of a word.

5. The system according to claim 1, wherein said at least one of the first input signals are the input signals corresponding to all characters of a word.

6. The system according to claim 1, wherein a second input signal corresponds to one of any of character positions within a word.

7. The system according to claim 1, wherein the characters are letters of a language.

8. The system according to claim 7, wherein the letters are assigned to four input signals.

9. A method of word predictive data entry using a database of words, the method comprising:

receiving at least one unambiguous, identified letter corresponding to any character position of a word being entered;

receiving at least one ambiguous input signal associated with a plurality of letters of a language; and

determining a word of the database based on said at least one unambiguous identified letter and said at least one ambiguous input signal.

10. The method of claim 9, wherein an identified letter corresponds to one of any of character positions of the word.

11. The method of claim 9, wherein said at least one ambiguous input signal corresponds to one of remaining characters of the word.

12. The method of claim 9, wherein said at least one ambiguous input signal comprises input signals corresponding to all of remaining characters of a desired word.

13. The method of claim 9, wherein the number of input signals to which the letters are assigned is four.

14. The method of claim 9, wherein the input signals are provided by interacting with keys.

15. The method of claim 9, wherein the input signals are provided by interacting with zones on a touch sensitive surface.

16. A method for enhanced word predictive data entry, the method comprising:

receiving at least one unambiguous input signal of a plurality of first input signals corresponding to identified characters;

receiving at least one ambiguous input signal of a plurality of second input signals each corresponding to a plurality of characters;

selecting a word of a database based on said at least one unambiguous input signal that corresponds to an identified character and said at least one ambiguous input signal.

17. The method of claim 16, wherein one of the identified characters corresponds to one of any of the character positions of the word.

18. The method of claim 16, wherein the plurality of second input signals are provided by interacting with corresponding plurality of keys.

19. The method of claim 18, wherein the number of keys is four.

20. The method of claim 19, wherein the keys are zones on a sensitive surface.

21. A method of data entry, comprising:

receiving, by a processor an input signal ambiguously associated with a plurality of characters of a language;

receiving by the processor an identified character of the language corresponding to one of any of character positions of a word being entered;

determining one or more words of a database based on receiving said identified character and said input signal ambiguously associated with the plurality of characters.

22. The method according to claim 21, comprising receiving the ambiguous input signals through key interactions.

23. The method according to claim 21, comprising receiving an identified character, through a speech recognition system after annunciation of the character, through a finger recognition system, or through a swiping action detection.

24. The method according to claim 21, wherein said characters are letters.
