Abstract

For performing touchscreen virtual touch control, a display module displays a control interface in response to detecting a finger touch of a finger on a touchscreen. A detection module detects a finger roll of the finger on the touchscreen and performs an action in response to detecting the finger roll.

Claims

1. An apparatus comprising:

a storage device storing machine-readable code;

a processor executing the machine-readable code, the machine-readable code comprising;

a display module displaying a control interface in response to detecting a finger touch of a finger on a touchscreen; and

a detection module detecting a finger roll of the finger on the touchscreen and performing an action in response to detecting the finger roll.

2. The apparatus of claim 1, detecting the finger roll comprising detecting a first finger portion remaining in a first position relative to the touchscreen while a second finger portion changes relative to the touchscreen.

3. The apparatus of claim 1, detecting the finger touch comprising detecting touching and holding the finger on the touchscreen for a minimum time interval.

4. The apparatus of claim 1, wherein the control interface is an enlarged window displaying a magnified portion of the touchscreen.

5. The apparatus of claim 1, wherein the action moves a cursor within the control interface in a direction of the finger roll.

6. The apparatus of claim 5, the detection module further detecting a finger confirmation by detecting a finger tap and activating a first icon selected by the cursor in response to the finger confirmation.

7. The apparatus of claim 1, wherein the control interface displays icons within a specified radius of the finger touch as enlarged icons with each enlarged icon disposed in a unique direction relative to a specified point of the control interface.

8. The apparatus of claim 7, wherein the action activates a first icon in a first unique direction parallel to a direction of the finger roll.

9. A method for touchscreen virtual track control comprising:

displaying, by use of a processor a control interface in response to detecting a finger touch of a finger on a touchscreen;

detecting a finger roll of the finger on the touchscreen; and

performing an action in response to detecting the finger roll.

10. The method of claim 9, detecting the finger roll comprising detecting a first finger portion remaining in a first position relative to the touchscreen while a second finger portion changes relative to the touchscreen.

11. The method of claim 9, detecting the finger touch comprising detecting touching and holding the finger on the touchscreen for a minimum time interval.

12. The method of claim 9, wherein the control interface is an enlarged window displaying a magnified portion of the touchscreen.

13. The method of claim 9, wherein the action moves a cursor within the control interface in a direction of the finger roll.

14. The method of claim 13, further comprising detecting a finger confirmation by detecting a finger tap and activating a first icon selected by the cursor in response to detecting the finger confirmation.

15. The method of claim 9, wherein the control interface displays icons within a specified radius of the finger touch as enlarged icons with each enlarged icon disposed in a unique direction relative to a center of the control interface.

16. The method of claim 15, wherein the action selects a first icon in a first unique direction parallel to a direction of the finger roll.

17. A program product comprising a storage device storing machine-readable code executed by a processor to perform the operations of:

displaying a control interface in response to detecting a finger touch of a finger on a touchscreen;

detecting a finger roll of the finger on the touchscreen; and

performing an action in response to detecting the finger roll.

18. The program product of claim 17, detecting the finger roll comprising detecting a first finger portion remaining in a first position relative to the touchscreen while a second finger portion changes relative to the touchscreen.

19. The program product of claim 17, detecting the finger touch comprising detecting touching and holding the finger on the touchscreen for a minimum time interval.

20. The program product of claim 17, wherein the control interface is an enlarged window displaying a magnified portion of the touchscreen.
