Abstract

A touch screen keyboard in which one of the user'"'"'s digits maintains contact with the touch screen, sliding across the screen below the keyboard with a magnifying cursor reaching upward from the digit onto the keyboard, enlarging one key at a time. The enlarged key is engaged when the user taps the screen anywhere else with another digit. Alternate configurations use fixed graphical buttons or accelerometer detected tapping for engagement of the enlarged key.

Claims

1. A virtual graphical keyboard for a touch screen consisting of multiple graphical onscreen keys and including in combination:

means for tracking the position of a first digit of a hand of a user as it maintains contact with and slides across a portion of said touch screen away from said virtual graphical keyboard;

means for graphically enlarging said keys of said virtual graphical keyboard, one at a time and at a fixed distance and fixed angle from said first digit in order to indicate to said user a key ready to be engaged;

means for graphically highlighting said key ready to be engaged;

means for engaging said key ready to be engaged when said user taps anywhere on said touch screen with at least one other digit; and

means for momentarily graphically altering said key ready to be engaged to indicate that engagement has occurred.

2. The combination according to claim 1 wherein tapping with more than one of said user'"'"'s said at least one other digit provides an alternate command related to said key ready to be engaged.

3. The combination according to claim 1 wherein at least one graphical touch-sensitive button for the engagement of said key ready to be engaged is located in a fixed position away from said virtual graphical keyboard.

4. The combination according to claim 1 wherein said portion of said touch screen said first digit of a hand of a user maintains contact with and slides across is located below said virtual graphical keyboard.

5. The combination according to claim 1 wherein said virtual graphical keyboard can be swiped across by a digit of said user'"'"'s hand to select at least one alternate set of commands for said graphical onscreen keys.

6. The combination according to claim 1 wherein said touch screen is built into a tablet computer.

7. The combination according to claim 1 wherein said touch screen is built into a multi-touch computerized display surface.

8. The combination according to claim 1 wherein said touch screen is built into a smartphone.

9. The combination according to claim 1 wherein said touch screen is built into a remote control device.

10. The combination according to claim 1 wherein said touch screen is built into a smart watch.

11. The combination according to claim 1 wherein a graphical magnifying glass cursor extends from said first digit of a hand of a user to said key ready to be engaged, and wherein said graphical magnifying glass cursor has a graphical button at the end that is beneath said first digit of a hand of a user.

12. The combination according to claim 1 wherein each time said user lifts said first digit of a hand of a user from said touch screen a space bar command is engaged.

13. A virtual graphical keyboard for a touch screen consisting of multiple graphical onscreen keys and including in combination:

means for tracking the position of a first digit of a hand of a user as it maintains contact with and slides across a portion of said touch screen away from said virtual graphical keyboard;

means for graphically enlarging said keys of said virtual graphical keyboard, one at a time and at a fixed distance and fixed angle from said first digit in order to indicate to said user a key ready to be engaged;

means for graphically highlighting said key ready to be engaged;

means for engaging said key ready to be engaged when said user taps anywhere, including on said touch screen and on a housing for said touch screen with at least one other digit, said taps anywhere being detected by a vibration sensor such as an accelerometer; and

means for momentarily graphically altering said key ready to be engaged to indicate that engagement has occurred.

14. The combination according to claim 13 wherein tapping with more than one of said user'"'"'s said at least one other digit provides an alternate command related to said key ready to be engaged.

15. The combination according to claim 13 wherein a graphical magnifying glass cursor extends from said first digit of a hand of a user to said key ready to be engaged, and wherein said graphical magnifying glass cursor has a graphical button at the end that is beneath said first digit of a hand of a user.

16. The combination according to claim 13 wherein said portion of said touch screen said first digit of a hand of a user maintains contact with and slides across is located below said virtual graphical keyboard.

17. The combination according to claim 13 wherein said virtual graphical keyboard can be swiped across by a digit of said user'"'"'s hand to select at least one alternate set of commands for said graphical onscreen keys.

18. The combination according to claim 13 wherein said housing is a smartphone.

19. The combination according to claim 13 wherein said housing is a remote control device.

20. The combination according to claim 13 wherein said housing is a wristwatch.

21. The combination according to claim 13 wherein each time said user lifts said first digit of a hand of a user from said touch screen a space bar command is engaged.
