Abstract

A method and apparatus which improves QWER-sive text input into an information handling system by gestures on or above a keyboard layout. It is known that languages have a characteristic frequency at which characters will appear. Relying upon such characteristics, a keyboard layout is generated in such a way that the area allocated to individual characters varies among the character set with larger areas being assigned to characters more likely to be used in a language selected by a user. Such enlargement of areas of response may either be visible to the user or concealed, in which latter case all of the individual characters appear to have been allocated areas of the same size.

Claims

1. A method for user input comprising:

generating a keyboard layout, wherein the areas allocated to individual characters varies among the character set with larger areas assigned to characters more likely to be used in a language selected by a user;

receiving a user input, wherein the user input includes a gesture that represents a plurality of characters and wherein a shape of the gesture is related to the position of the plurality of characters within the keyboard layout;

identifying a string of characters associated with the gesture;

and

providing the identified string as text input.

2. A method according to claim 1 wherein the area allocated is visually apparent to the user.

3. A method according to claim 1 wherein the area allocated is concealed from the view of the user.

4. A method according to claim 1 wherein identifying a string associated with the gesture comprises:

identifying a starting position;

recording a character based on the starting position with respect to the keyboard layout; and

allocating an enlarged area to an anticipated next character based upon the most likely next character to be used in the language selected by the user.

5. A method according to claim 1 wherein identifying a string associated with the gesture comprises:

identifying a change in direction;

recording a character based on a position of the change in direction with respect to the keyboard layout; and

allocating an enlarged area to an anticipated next character based upon the most likely next character to be used in the language selected by the user.

6. A method according to claim 1 wherein identifying a string associated with the gesture comprises:

generating a character based on a position with respect to keyboard layout;

allocating an enlarged area to an anticipated next character based upon the most likely next character to be used in the language selected by the user; and

iterating recording and allocating to assemble a character string.

7. An apparatus accommodating user input comprising:

an end user device having a processor, a display driven by the processor and memory accessible to said processor; and

computer executable program code stored in said memory and operating when executed by said processor to;

generate a keyboard layout wherein the area allocated to individual characters varies among the character set with larger areas assigned to characters more likely to be used in a language selected by a user;

receive a user input, wherein the user input includes a gesture that represents a plurality of characters and wherein a shape of the gesture is related to the position of the plurality of characters within a keyboard layout;

identify a string of characters associated with the gesture; and

provide the identified string as text input.

8. An apparatus according to claim 7 wherein the area allocated is visually apparent to the user.

9. An apparatus according to claim 7 wherein the area allocated is concealed from the view of the user.

10. An apparatus according to claim 7 wherein identifying a string associated with the gesture comprises:

identifying a starting position;

recording a character based on the starting position with respect o the keyboard layout; and

allocating an enlarged area to an anticipated next character based upon the most likely next character to be used in the language selected by the user.

11. An apparatus according to claim 7 wherein identifying a string associated with the gesture comprises:

identifying a change in direction;

recording a character based on a position of the change in direction with respect to the keyboard layout; and

allocating an enlarged area to an anticipated next character based upon the most likely next character to be used in the language selected by the user.

12. An apparatus according to claim 7 wherein identifying a string associated with the gesture comprises:

recording a character based on a position with respect to the keyboard layout;

allocating an enlarged area to an anticipated next character based upon the most likely next character to be used in the language selected by the user; and

iterating recording and allocating to assemble a character string.

13. An apparatus facilitating a text string input into an end user device which has a processor, a display and memory accessible to said processor, the apparatus comprising:

a computer readable storage medium; and

computer readable program code stored in said computer readable storage medium and operable when executed by a processor to;

generate a keyboard layout wherein the area allocated to individual characters varies among the character set with larger areas assigned to characters more likely to be used in a language selected by a user;

receive a user input, wherein the user input includes a gesture that represents a plurality of characters and wherein a shape of the gesture is related to the position of the plurality of characters within a keyboard layout;

identify a string of characters associated with the gesture; and

provide the identified string as text input.

14. An apparatus according to claim 13 wherein the area allocated is visually apparent to the user.

15. An apparatus according to claim 13 wherein the area allocated is concealed from the view of the user.

16. An apparatus according to claim 13 wherein identifying a string associated with the gesture comprises:

identifying a starting position;

recording a character based on the starting position with respect to the keyboard layout; and

allocating an enlarged area to an anticipated next character based upon the most likely next character to be used in the language selected by the user.

17. An apparatus according to claim 13 wherein identifying a string associated with the gesture comprises:

identifying a change in direction;

recording a character based on a position of the change in direction with respect to the keyboard layout; and

allocating an enlarged area to an anticipated next character based upon the most likely next character to be used in the language selected by the user.

18. An apparatus according to claim 13 wherein identifying a string associated with the gesture comprises:

recording a character based on a position with respect to the keyboard layout;

allocating an enlarged area to an anticipated next character based upon the most likely next character to be used in the language selected by the user; and

iterating recording and allocating to assemble a character string.
