The determination mode in false-touch prevention region can have many kinds, for example, can investigate the mobile end to different model or profile for the user group
Situations such as holding mode at end and posture, the screen area of easy for most users false touch is set to false-touch prevention region, and is moving
Dynamic terminal completes before dispatching from the factory to arrange.And for example, user, before beginning to use mobile terminal, can also pass through holding mode input function,
The related data that user grips mobile terminal is gathered by mobile terminal, goes out the area of the easy false touch of user according to the data analysiss of collection
Domain, this region is set as false-touch prevention region.The present embodiment is not specifically limited to the quantity in false-touch prevention region.Preferably, prevent
The shape in false touch region and/or size also voluntarily can be adjusted by user.
, it judges touch point by sensing capacitance variations produced by human body touch taking capacitive touch screen as a example.Its
There are two groups of holding wires：Drives line and the line of induction, drives line transmission signal, the line of induction detects the change of capacitance.When finger touches
When touching on the metal layer, due to the presence of human body electric field, finger and touch screen surface form a coupled capacitor, for high-frequency electrical
For stream, electric capacity is direct conductor, and then finger siphons away the electric current of a very little from contact point.Have impact on touch point nearby two
Coupling between electrode, thus change the capacitance between this two electrodes.During detection mutual capacitance size, drives line direction

Make.Wherein, (ACTION_DOWN) event of pressing is initiation event.The time conduct pressing event triggering moment will be detected
The time of touch event triggering.Event triggering moment will be pressed and be constantly compared with comparing.If this presses event triggering moment
Early than this comparison moment it is determined that this press event occur described successive projection duration exceed setting very first time threshold value it
Before.If this is pressed event triggering moment and is later than this comparison moment it is determined that this presses event generation in described successive projection duration
After exceeding setting very first time threshold value.
For occurring to exceed, in this successive projection duration, the touch event setting after very first time threshold value, obtain and touch thing
The touch information of part, so that it is determined that the contact coordinate that touch event includes.If at least one contact coordinate of touch event is located at
It is determined that described touch event acts in default false-touch prevention region in default false-touch prevention region.
Step 130, when the duration of described touch event exceedes setting the second time threshold, abandon responding described touching
Touch event.
Wherein, the duration of touch event be press event triggering moment to the event triggering moment of lifting passed through when
Between.For example, mobile terminal detect press event triggering when, record current time be 10 when 23 points 17 seconds 20 milliseconds.Mobile
Terminal persistently detects this touch event.Detect lift event triggering when, record current time be 10 when 23 points 50 seconds 30 milliseconds.
By upper, mobile terminal can determine the duration of this touch event be 33 seconds 10 milliseconds.
The determination mode of the second time threshold has many kinds, and the present embodiment is not especially limited.For example, it is possible to investigation user
Colony executes the operating time (including clicking operation time and slide time etc.) of normal touch operation.Mobile terminal is to this
Operating time carries out statistical analysiss, so that it is determined that the second time threshold, and complete setting of operating time before mobile terminal dispatches from the factory
Fixed.And for example, user, before beginning to use mobile terminal, can enter operating time calibration function, gather the machine by mobile terminal
Data correlation time of the normal touch operation of user, goes out the operation of this user's normal touch operation according to the data analysiss of collection
Time, thus set the second time threshold according to the operating time adjustment after this calibration.
When executing this step, successive projection duration in default false-touch prevention region for the finger is exceeded the setting very first time
After threshold value, the duration of the touch event in default false-touch prevention region is occurred to be compared with setting the second time threshold
Relatively.If the duration of this touch event exceedes setting the second time threshold, abandon reporting the corresponding touch of this touch event
It is located at the contact in default false-touch prevention region in point, normally report and in the corresponding touch point of this touch event, be located at default false-touch prevention
