Abstract

A data entry system, having an input interface adapted to identify a plurality of user interactions. The system includes a processor adapted to associate user interactions identified by the input interface with a plurality of letters of the alphabet, such that all the letters of the alphabet are assigned to at most eight user interactions. Most of the letters are assigned to specific user interactions according to one or more features of their shape in their printed form, such that most of the letters assigned to each user interaction have the same shape feature.

Claims

1. A data entry system, comprising:

an input interface adapted to identify a plurality of user interactions;

a processor adapted to associate user interactions identified by the input interface with a plurality of letters of the alphabet, such that all the letters of the alphabet are assigned to at most eight user interactions, and most of the letters are assigned to specific user interactions according to one or more features of their shape in their printed form, such that most of the letters assigned to each user interaction have the same shape feature.

2. The system of claim 1, wherein the shape feature of at least one of the user interactions comprises the number of legs the letter has in its printed form.

3. The system of claim 2, wherein the shape feature of at least one of the user interactions comprises whether the letter has an uneven number of legs.

4. The system of claim 1, wherein the shape feature of at least one of the user interactions comprises whether the letter has a large or a small arc.

5. The system of claim 4, wherein the shape feature of at least one of the user interactions comprises whether the letter has a large arc.

6. The system of claim 1, wherein the shape feature of at least one of the user interactions comprises whether the letter has an upper or lower horizontal line.

7. The system of claim 6, wherein the shape feature of at least one of the user interactions comprises whether the letter has a lower horizontal line.

8. The system of claim 1, wherein at least one of the user interactions is associated only with the letters having a specific feature shape.

9. The system of claim 8, wherein one of the user interactions is associated only with letters having two legs.

10. The system of claim 1, wherein at least one of the user interactions is associated with all the letters having a specific feature.

11. The system of claim 10, wherein one of the user interactions is associated all the letters having a large arc.

12. The system of claim 1, wherein the user interactions with which the letters are associated are interpreted as ambiguously entering all the letters with which they are associated.

13. The system of claim 1, wherein the user interactions with which the letters are associated are interpreted as a first step of selecting unambiguously one of the letters associated with the user interactions.

14. The system of claim 1, wherein the user interactions comprise pressing of keys.

15. The system of claim 1, wherein the user interactions comprise sweeping gestures on a touch surface in different directions.

16. The system of claim 1, wherein none of the user interactions are assigned a plurality of letters assigned to a same key in the telephone keypad.

17. A data entry system, comprising:

a touch screen;

a processor;

an operating system running on the processor adapted to interpret sweeping gestures on the touch screen and perform tasks responsive to the sweeping gestures; and

an input module running on the processor adapted to identify a specific sweeping gesture not identified by the operating system and to define a location of a keyboard on the touch screen responsive to the identified sweeping gesture.

18. The system of claim 17, wherein the input module is adapted to identify two gestures provided concurrently at different locations on the screen.

19. The system of claim 18, wherein the input module is adapted to define a first portion of the keyboard at a location of a first one of the two gestures and a second portion of the keyboard at a location of a second one of the two gestures.

20-21. -21. (canceled)

22. A data entry system, comprising:

a touch surface; and

a processor adapted to define a plurality of letter zones, each assigned a plurality of letters, on the touch surface, to identify sweeping gestures on the touch surface beginning from the touch surface and to associate the identified sweeping gestures with one of the letters associated with the letter zone at which it begins, according to the direction of the gesture, without relation to the starting point of the sweeping gesture in the letter zone.
