Abstract

A graphical user interface for improved text character entry is disclosed. In some embodiments, the graphical user interface may be displayed on a mobile communications device. The graphical user interface may display a message field, a soft keyboard, and at least one visual foveal echo field. The message field may display text characters of a message being authored by a user interacting with the soft keyboard. The visual foveal echo field may be placed adjacent to a soft keyboard row and contain a portion of the message being authored by the user.

b) providing on the touch screen display a soft keyboard including a plurality of rows of soft keys, the soft keys including character keys which when touched by the user enter characters into the message field; and

c) providing on the touch screen display a plurality of visual foveal echo fields, each one of the plurality of echo fields located between different consecutive rows of the plurality of rows of soft keys and providing an unobstructed view of the consecutive rows, each echo field for containing at least a subset of any characters entered by the user into the message field, for containing only characters entered by the user, and for containing the characters in the order entered wherein;

i. a first visual foveal echo field of the plurality is located between a first row and a second row of soft keys, and

ii. a second visual foveal echo field of the plurality is located between the second row and a third row of soft keys.

2. The mobile communications device of claim 1 further comprising instructions for:

providing on the touch screen display a vertical up down key that when touched presents separate up and down keys to permit the user to select the row of characters in the message field that are presented in at least one visual foveal echo field.

3. The mobile communications device of claim 1 further comprising instructions for:

providing on the touch screen display a horizontal left right key that when touched presents separate left and right keys to permit the user to select the characters in a particular row in the message field that are presented in at least one visual foveal echo field.

9. The mobile communications device of claim 1, wherein the instructions provide that each foveal echo field contains the same subset of characters.

11. The mobile communications device of claim 9, wherein the instructions provide that the subset contains the last character entered.

13. The mobile communications device of claim 1, wherein the instructions provide that the plurality of rows of soft keys includes four rows of soft keys, the plurality of visual foveal echo fields includes three visual foveal echo fields, and:

i. the first visual foveal echo field is located between the first row and second row of soft keys,

ii. the second visual foveal echo field is located between the second row and third row of soft keys, and

iii. the third visual foveal echo field is located between the third row and fourth row of soft keys.

4. A mobile communications device comprising a touch screen display, at least one processor, memory, and at least one program, wherein the at least one program is stored in the memory and configured to be executed by the at least one processor, the at least one program including instructions for:

a) providing on the touch screen display a message field for displaying text characters entered by a mobile communications device user

b) providing on the touch screen display a soft keyboard including six rows of text character keys which when touched by the user enter text characters into the message field, the rows arranged such that

the first row has only the text characters Q, W, E, R and T;

the second row has only the text characters Y, U, I, O and P;

the third row has only the text characters A, S, D, F and G;

the fourth row has only the text characters H, J, K and L;

the fifth row has only the text characters Z, X, C, V and B; and

the sixth row has the text characters N and M; and

c) providing on the touch screen display four visual foveal echo fields, each echo field for containing at least a subset of any text characters entered by the user into the message field, for containing only characters entered by the user, and for containing the characters in the order entered wherein;

i. the first visual foveal echo field is located between the message field and the first row of soft keys,

ii. the second visual foveal echo field is located between the second row and third row of soft keys,

iii. the third visual foveal echo field is located between the fourth row and fifth row of soft keys, and

iv. the fourth visual foveal echo field is located below the sixth row of soft keys.

5. The mobile communications device of claim 4 wherein the instructions provide that the first, third and fifth rows are arranged left justified, the second row first character Y is positioned below the first row characters Q and W, the fourth row first character H is positioned below the third row characters S and D, and the sixth row first character N is positioned below the fifth row character C.

6. The mobile communications device of claim 4 wherein the instructions provide that the first, third and fifth rows are arranged left justified, the second row first character Y is positioned below the first row characters W and E, the fourth row first character H is positioned below the third row characters D and F, and the sixth row first character N is positioned below the fifth row characters V and B.

7. The mobile communications device of claim 4 further comprising instructions for:

providing on the touch screen display a vertical up down key that when touched presents separate up and down keys to permit the user to select the row of text characters in the message field that are presented in at least one visual foveal echo field.

8. The mobile communications device of claim 4 further comprising instructions for:

providing on the touch screen display a horizontal left right key that when touched presents separate left and right keys to permit the user to select the text characters in a particular row in the message field that are presented in at least one visual foveal echo field.

10. The mobile communications device of claim 4 wherein the instructions provide that each foveal echo field contains the same subset of characters.

12. The mobile communications device of claim 10, wherein the instructions provide that the subset contains the last character entered.

14. A method for implementing a graphical user interface using a mobile communications device, the method comprising:

a) providing, on a visual display of the mobile communications device, a message field for displaying characters entered by a mobile communications device user;
