Abstract

A touch control method for a drag gesture, which identifies a motion of the drag gesture executed on the touch device by an object by way of a control module of the touch device with control signal being generated corresponding to the drag gesture for being used by an main unit as subsequent control function with a first reference time being defined in the control module, includes detecting occurrence of the drag generated during the object moving on the touch device and starting counting time at the same time; determining time of the object staying on the touch device; outputting a control signal representing the motion of drag gesture for being used by the main unit in case of the staying time being exceeding the first reference time and the object keeping moving a small distance on the touch device; and keeping outputting the control signal to the main unit during the object stopping moving and keeping contacting with the touch device and stopping outputting the control signal to the main unit once the object detaches from the touch device.

Claims

1. A touch control method for a drag gesture, which identifies a motion of the drag gesture executed on the touch device by an object by way of a control module of the touch device with control signal being generated corresponding to the drag gesture for being used by an main unit as subsequent control function with a first reference time being defined in the control module, comprising following steps:

A) detecting occurrence of the drag generated during the object moving on the touch device and starting counting time at the same time;

B) determining time of the object staying on the touch device and continuing step (C) in case of the staying time being exceeding the first reference time and the object keeping moving a small distance on the touch device;

C) outputting a control signal representing the motion of drag gesture for being used by the main unit; and

D) keeping outputting the control signal to the main unit during the object stopping moving and keeping contacting with the touch device and stopping outputting the control signal to the main unit once the object detaches from the touch device.

2. The touch control method for a drag gesture as defined in claim 1, wherein a reference displacement is defined in the control module and a displacement signal created by the object on the touch device is detected in step B) and the control signal keeps outputting in step D) in case of the displacement of the object exceeding the reference displacement.

3. The touch control method for a drag gesture as defined in claim 1, wherein a second reference time is defined in the control module and the control signal keeps outputting the control signal in step D) for being used by the main unit during the object stopping moving and keeping contacting with the touch device.

4. A control module, which is used for identifying a motion of drag gesture executed on a touch device by an object with control signal being generated corresponding to the drag gesture for being used by an main unit for performing subsequent control function, comprising:

an operation unit, generating a touch signal corresponding to every occurrence of the object being on the touch device and the touch signal being generated at initiation of the occurrence and terminated at end of the occurrence; and

a gesture unit, being connected to the operation unit and the main unit for receiving the touch signal, figuring out time duration of all the occurrence for identifying what motion of the object is and defining a first reference time therein;

wherein, the gesture unit determines time of the object staying on the touch device being exceeding the first reference time and outputs a control signal representing the motion of drag for being used by the main unit; and

keeping outputting the control signal to the main unit during the object stopping moving and keeping contacting with the touch device and stopping outputting the control signal to the main unit once the object detaches from the touch device.

5. The control module as defined in claim 4, wherein a reference displacement is defined in the gesture unit and a displacement signal created by the object on the touch device is detected with the gesture unit and the control signal keeps outputting in case of the displacement of the object exceeding the reference displacement.

6. The control module as defined in claim 4, wherein a second reference time is defined in the gesture unit and the gesture unit keeps outputting the control signal for being used by the main unit during the object stopping moving and keeping contacting with the touch device.
