Abstract

A keyboard is divided into a number of large zones each large zone having a number of small zones. The large zones, together, include substantially all of the letters of a language. A word predictive system analyzes the user'"'"'s interaction with the large zones relating to the small zones to predict a word.

Claims

1. A data entry system comprising:

A keyboard having a number of rows of letter divided into at least one large zone wherein each large zone having a number of small zones, wherein said zones together include substantially all of the letters of a language; and

A word predictive system;

Wherein upon receiving an interaction with a small zone, a system gives an error distance value to each of at least a number of letters of the interacted large zone;

wherein the error distance value of a letter from the interacted small zone is calculated based on its distance from the interaction impact, and wherein the error distance value of a letter from another small zone of said interacted large zone is calculated based on its distance from the interaction impact plus a penalty value; and

wherein

upon receiving a sequence of interaction with the large zones, the system selects a number of corresponding words form a database of words wherein their total error value of their corresponding characters is less than a predefined or dynamically defined value.

2. The system of claim 1, wherein each large zone is divided into three the small zones.

3. The system of claim 2, wherein the keyboard is divided into two large zones.

4. The system of claim 1, wherein the error distance is calculated based on the distance from the letter on which an impact is provided and another letter.

5. The system of claim 1, wherein the error distance is calculated based on the distance from the impact point and a predefined point related to a letter.

6. The system of claim 1, wherein among the considered words, the system gives priority to the word that has the highest frequency of use.

7. The system of claim 1, wherein among the considered words, the system gives priority to the word that has the lowest total error distance value.

8. The system of claim 1, or 2, or 3, wherein said keyboard is one of at least a QWERTY, a QWERTZ, and an AZERTY keyboard.

9. The system of claim 1, or 3, wherein each of the letters R and T, and/or each of the letters F and G, and/or each of the letters V and B are assigned to a different large zone

10. The system of claim 1, wherein at least one of the letters situated on an edge of the keyboard is entered precisely upon interaction with said letter.
