Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
In order to improve the security of controlling of touch technology, the embodiment of the invention provides a kind of touch control method, as shown in Figure 1, comprising:
101, detect touch control operation, obtain induced signal.
For example, the touch screen terminal can detect whether there is induced signal by the sensor of touch-control surface, namely detects the user and whether it has been carried out touch control operation.Detecting when having induced signal, this induced signal is gathered.Wherein, this sensor can be capacitance type sensor, piezoelectric transducer etc.
102, according to described induced signal, obtain touch points position and touch-control eigenwert.
In the present embodiment, described touch-control eigenwert can be the intensity level of induced signal, and correspondingly, the aftermentioned activation threshold value is for triggering intensity threshold.Perhaps, described touch-control eigenwert can be the frequency values of induced signal, and correspondingly, the aftermentioned activation threshold value is for triggering frequency threshold.Perhaps, described touch-control eigenwert can be the intensity level of induced signal and the frequency values of induced signal, and correspondingly, the aftermentioned activation threshold value is for triggering intensity threshold and triggering frequency threshold.In addition, described touch-control eigenwert is not limited to above-mentioned value, can also be other value, for example application of force intensity level etc.
For example, the touch screen terminal positions analysis according to the induced signal that collects, and draws the position of touch points.Simultaneously, obtain intensity level or frequency values or intensity level and frequency values in this induced signal that collects.
103, according to described touch points position, obtain predefined activation threshold value;
For example, the touch screen terminal also can be stored a position threshold mapping table in advance, comprises the correspondence relationship information of touch points position and activation threshold value in this position threshold mapping table.The touch screen terminal reads this position threshold mapping table after having gathered induced signal and it is analyzed, inquire about this position threshold mapping table, finds out the activation threshold value corresponding with this touch points position.
Perhaps, the touch screen terminal also can be stored the position threshold mapping table corresponding with each operation interface in advance, comprises touch points position in this operation interface and the correspondence relationship information of activation threshold value in this position threshold mapping table.The touch screen terminal is after having gathered induced signal and it has been analyzed, determine the operation interface of the current demonstration of touch screen, and read corresponding position threshold mapping table according to the operation interface of current demonstration, and inquire about this position threshold mapping table, find out the activation threshold value corresponding with this touch points position.
104, when determining that according to described touch-control eigenwert and described activation threshold value input is effective, handle accordingly according to described touch points position.
For example, can judge whether input is effective according to intensity level and the triggering intensity threshold of induced signal.When triggering intensity threshold, judge input effectively at the intensity level of induced signal, determine and touch points position corresponding key function, carry out the processing corresponding with this keypress function this moment.When triggering intensity threshold, judge that input is invalid at the intensity level of induced signal, do not carry out any processing this moment.
Perhaps, also can judge whether input is effective according to frequency values and the triggering frequency threshold of induced signal.When triggering frequency threshold, judge input effectively at the frequency values of induced signal, determine and touch points position corresponding key function, carry out the processing corresponding with this keypress function this moment.When triggering frequency threshold, judge that input is invalid at the frequency values of induced signal, do not carry out any processing this moment.
Perhaps, also can judge whether input is effective according to the intensity level of induced signal and frequency values and the triggering frequency threshold of triggering intensity threshold and induced signal.More than or equal to triggering intensity threshold, and the frequency values of induced signal judges input effectively when triggering frequency threshold, determines and touch points position corresponding key function, carries out the processing corresponding with this keypress function this moment at the intensity level of induced signal.Less than triggering intensity threshold, perhaps the frequency values of induced signal judges that input is invalid when triggering frequency threshold, does not carry out any processing this moment at the intensity level of induced signal.
In addition, the corresponding relation of touch points position and activation threshold value can be Default Value in the touch screen terminal, also can be arranged voluntarily by the user.For example, the user can set indication to touch screen terminal input threshold value, after the touch screen terminal receives this threshold value setting indication, can set indication according to this threshold value determines will store as the touch points position of setting object and the corresponding relation of activation threshold value as the touch points position of setting object and corresponding activation threshold value thereof.Wherein, the mode that the user imports threshold value setting indication can realize in several ways that for example, the user can touch a bit on the screen, and this point is set at as the touch points position of setting object, manually imports the numerical value of activation threshold value.Perhaps, the user also can touch a bit on the screen, this point is set at as the touch points position of setting object, and, this touching to this point is operated corresponding triggering eigenwert as activation threshold value.
The touch control method that present embodiment provides, by when detecting touch control operation, obtaining induced signal, obtain touch points position and touch-control eigenwert according to described induced signal, obtain the corresponding activation threshold value in predefined and described touch points position, and when determining that according to described touch-control eigenwert and described activation threshold value input is effective, handle accordingly.Therefore, can reduce the maloperation to the high button of importance effectively, thereby improve the security of controlling of touch technology.
In a last embodiment, described touch-control eigenwert can be the intensity level of induced signal, the perhaps frequency values of induced signal, perhaps, the intensity level of induced signal and frequency values.Correspondingly, described activation threshold value can perhaps trigger frequency threshold for triggering intensity threshold, perhaps triggers intensity threshold and triggers frequency threshold.Below, in conjunction with above different situations a last embodiment is done further specifically to describe in detail.
As shown in Figure 2, the present embodiment touch control method comprises:
201, when detecting touch control operation, obtain induced signal.
For example, comprise in the touch screen terminal that one or several are distributed in the sensor of touch-control surface, this sensor is gathered in real time to the induced signal in the effective coverage.When touch object touched touch screen, sensor detected the variation of induced signal, by Acquisition Circuit this induced signal was gathered in real time immediately.Wherein, the induced signal that collects can be because the electric signal that capacitance variations, electromagnetic change, pressure variation etc. cause or intensive quantity or the frequency quantity of magnetic signal.
202, according to described induced signal, obtain the intensity level of touch points position and induced signal.
For example, the touch screen terminal positions analysis according to the induced signal that collects, and draws the position of touch points.Wherein, the method for positioning analysis can not repeat them here referring to prior art.
Simultaneously, the intensity level in the induced signal that collects of touch screen terminal measurement.In addition, this intensity level can be measured by the sensor that is used for the location on the contactor control device, also can be by additional measuring specially for dynamometry, vibration measuring sensor moving, that survey magnetic variationization.
203, according to described touch points position, obtain predefined triggering intensity threshold.
For example, the touch screen terminal can not distinguished operation interface, and a same position of touching is arranged a triggering intensity threshold.For example, suppose in each operation interface of touch screen terminal, important relatively buttons such as " homepage " key all are arranged at the below, interface, be positioned at the corresponding positions such as " homepage " key of below, interface at this, a triggering intensity threshold higher than the triggering intensity threshold of other common key-press is set respectively, and this corresponding relation is stored in the position threshold mapping table.At this moment, in step 203, the touch screen terminal reads this position threshold mapping table, inquires about this position threshold mapping table, finds out the triggering intensity threshold corresponding with this touch points position.
Perhaps, the touch screen terminal also can arrange different triggering intensity thresholds to a same position of touching at different operation interfaces.For example, suppose in each operation interface of touch screen terminal, important relatively button such as " homepage " key is in the on-fixed position, at the corresponding positions such as " homepage " key in each operation interface, a triggering intensity threshold higher than the triggering intensity threshold of other common key-press is set respectively, and this corresponding relation is stored in the position threshold mapping table.At this moment, in step 203, the touch screen terminal reads this position threshold mapping table, inquires about this position threshold mapping table, finds out the triggering intensity threshold corresponding with the touch points position in this operation interface.
In addition, the touch points position at different operating interface can be stored in the same position threshold mapping table with the corresponding relation that triggers intensity threshold, perhaps, also the touch points position at different operating interface and the corresponding relation that triggers intensity threshold can be stored in the corresponding different position threshold mapping table of each operation interface in.
204, according to intensity level and the described triggering intensity threshold of described induced signal, judge whether input is effective.If judge that input effectively, then enters step 205, otherwise, skip to step 206.
For example, the touch screen terminal can judge that input effectively at the intensity level of induced signal when triggering intensity threshold.When triggering intensity threshold, judge that input is invalid at the intensity level of induced signal.

For example, the touch screen terminal is determined the corresponding keypress function in touch points position, carries out the corresponding processing of this keypress function.The specific implementation that the touch screen terminal is carried out the corresponding processing of this keypress function can not repeat them here referring to prior art.
For example, when capacitance touching control equipment such as mobile phone are pressed button, this touch control device is judged by the oscillatory type sensor and is obtained the intensity level of induced signal of certain position more than or equal to the triggering intensity threshold of this position, be that this touch control operation has caused that the bigger variation of capacitance and impulsive force are also very big, this touch control device judges that input effectively, judge that namely this touch control operation is normal running, carry out the corresponding processing in this position.
206, will not respond.
For example; when capacitance touching control equipment such as mobile phone are pressed button; the other parts of hand are missed other button of running on the interface through regular meeting; at this moment; this touch control device is judged the intensity level of induced signal that obtains certain position by the oscillatory type sensor less than the triggering intensity threshold of this position, and namely this touch control operation has caused the bigger variation of capacitance but impulsive force is little, and this touch control device judges that input is invalid; judge that namely this touch control operation is maloperation, will not respond.

Simultaneously, the frequency values in the induced signal that collects of touch screen terminal measurement.In addition, this frequency values can be measured by the sensor that is used for the location on the contactor control device, also can measure specially by the additional vibration measuring sensor moving, that survey magnetic variationization that is used for.
303, according to described touch points position, obtain predefined triggering frequency threshold.
For example, the touch screen terminal can not distinguished operation interface, and a same position of touching is arranged a triggering frequency threshold.For example, suppose in each operation interface of touch screen terminal, important relatively buttons such as " homepage " key all are arranged at the below, interface, be positioned at the corresponding positions such as " homepage " key of below, interface at this, a triggering frequency threshold higher than the triggering frequency threshold of other common key-press is set respectively, and this corresponding relation is stored in the position threshold mapping table.At this moment, in step 303, the touch screen terminal reads this position threshold mapping table, inquires about this position threshold mapping table, finds out the triggering frequency threshold corresponding with this touch points position.
Perhaps, the touch screen terminal also can arrange different triggering frequency thresholds to a same position of touching at different operation interfaces.For example, suppose in each operation interface of touch screen terminal, important relatively button such as " homepage " key is in the on-fixed position, at the corresponding positions such as " homepage " key in each operation interface, a triggering frequency threshold higher than the triggering frequency threshold of other common key-press is set respectively, and this corresponding relation is stored in the position threshold mapping table.At this moment, in step 303, the touch screen terminal reads this position threshold mapping table, inquires about this position threshold mapping table, finds out the triggering frequency threshold corresponding with the touch points position in this operation interface.

304, according to frequency values and the described triggering frequency threshold of described induced signal, judge whether input is effective.If judge that input effectively, then enters step 305, otherwise, skip to step 306.
For example, the touch screen terminal can judge that input effectively at the frequency values of induced signal when triggering frequency threshold.When triggering frequency threshold, judge that input is invalid at the frequency values of induced signal.
305, respond accordingly according to described touch points position.
For example, the touch screen terminal is determined the corresponding keypress function in touch points position, carries out the corresponding processing of this keypress function.The specific implementation that the touch screen terminal is carried out the corresponding processing of this keypress function can not repeat them here referring to prior art.
For example, when capacitance touching control equipment such as mobile phone are pressed button, this touch control device is judged by the oscillatory type sensor and is obtained the frequency values of induced signal of certain position more than or equal to the triggering frequency threshold of this position, be that this touch control operation has caused that the bigger variation of capacitance and frequency are also very high, this touch control device judges that input effectively, judge that namely this touch control operation is normal running, carry out the corresponding processing in this position.
