Touchscreen virtual track control
View Patent ↗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.
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 that displays a control interface in response to detecting a finger touch of a finger on a touchscreen, wherein the control interface displays icons within a specified radius of the finger touch as enlarged icons with each icon disposed in a unique direction relative to a specified point of the control interface; and
a detention module that detects a finger roll of the finger on the touchscreen and activating a first icon in a direction relative to the specified point most parallel to a finger roll direction 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 , the detection module further detecting a finger confirmation by detecting a finger tap and activating a first icon in response to the finger confirmation.
6. The apparatus of claim 1 , wherein the action activates a first icon in a first unique direction parallel to a direction of the finger roll.
7. 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, wherein the control interface displays icons within a specified radius of the finger touch as enlarged icons with each icon disposed in a unique direction relative to a specified point of the control interface;
detecting a finger roll of the finger on the touchscreen; and
activating a first icon in a direction relative to the specified point most parallel to a finger roll direction in response to detecting the finger roll.
8. The method of claim 7 , 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.
9. The method of claim 7 , detecting the finger touch comprising detecting touching and holding the finger on the touchscreen for a minimum time interval.
10. The method of claim 7 , wherein the control interface is an enlarged window displaying a magnified portion of the touchscreen.
11. The method of claim 7 , further comprising detecting a finger confirmation by detecting a finger tap and activating a first icon in response to detecting the finger confirmation.
12. The method of claim 7 , wherein the action selects a first icon in a first unique direction parallel to a direction of the finger roll.
13. A program product comprising a non-transitory 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, wherein the control interface displays icons within a specified radius of the finger touch as enlarged icons with each icon disposed in a unique direction relative to a specified point of the control interface;
detecting a finger roll of the finger on the touchscreen; and
activating a first icon in a direction relative to the specified point most parallel to a finger roll direction in response to detecting the finger roll.
14. The program product of claim 13 , 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.
15. The program product of claim 13 , detecting the finger touch comprising detecting touching and holding the finger on the touchscreen for a minimum time interval.
16. The program product of claim 13 , wherein the control interface is an enlarged window displaying a magnified portion of the touchscreen.
17. The program product of claim 13 , the operations further comprising detecting a finger confirmation by detecting a finger tap and activating a first icon in response to detecting the finger confirmation.
18. The program product of claim 13 , wherein the action selects a first icon in a first unique direction parallel to a direction of the finger roll.
