Fig. 2A is refer to, the Fig. 2A is a kind of flow of gesture identification method according to another exemplary embodiment Figure, the gesture identification method can apply in terminal, and this method can realize step including several as follows:

Step 201:The touch signal of multi collect difference gesture, obtains multiple sample datas, and the different gestures include should Upper oarsman's gesture raises gesture with this.

In order to upper stroke and raising both gestures and making a distinction and identify, need to be based respectively on two kinds of hands in advance The touch signal of gesture triggering carries out model training, to obtain being subsequently based respectively on the touch signal that both gestures are triggered The specified Logic Regression Models of the corresponding gesture of identification.Wherein, the process of model training is as described in step 201 to step 202.

It that is to say, it is necessary first to the touch signal of both different gestures of multi collect, multiple sample datas are obtained, so as to Model training is carried out in being subsequently based on the plurality of sample data.

Wherein, the touch signal includes mean place information or alternate position spike information, and the mean place information refers to the slip The average value of all positional informations on track, the alternate position spike information refer between the initial position of the sliding trace and end position Location variation.

For example, in a kind of possible implementation, the touch signal can include mean place information.When terminal is based on When different gestures collect touch signal, can the sliding trace based on different gestures, obtain sliding trace on positional information, Further, touch point when each positional information can be the gesture contact screen is in corresponding touch coordinate at different moments. It that is to say, terminal can obtain touch coordinate by condition of the time, for example, every prefixed time interval, obtain touching for touch point Touch coordinate.Afterwards, the terminal determines the average value of acquired multiple touch coordinates, obtains mean place information, and this is put down Equal positional information is defined as sample data.

Wherein, the prefixed time interval can also can be write from memory by user's self-defined setting according to the actual requirements by the terminal Recognize setting, the embodiment of the present application is not limited this.For example, the prefixed time interval is 1 millisecond.

It should be noted that the foundation on coordinate system can be using the screen center of terminal as origin, or, can also Be some drift angle using the screen of terminal as origin, the embodiment of the present application is not limited this.

For another example, in alternatively possible implementation, the touch signal can also include alternate position spike information, that is to say, For each performed operation of different gestures, the touch signal that terminal can be triggered based on the gesture, sliding trace is gathered Positional information corresponding to positional information corresponding to initial position and end position, afterwards, determine position corresponding to the initial position Location variation between positional information corresponding to information and the end position, and identified location variation is defined as sample Notebook data.

Certainly, it is necessary to explanation, be only here using the touch signal include mean place information or alternate position spike information as Example illustrate, in practical application scene, the touch signal can also including touching intensity etc. information, at this point it is possible to pass through Pressure inductor obtains the touching intensity information, and the embodiment of the present application is not limited this.

Step 202:Based on the plurality of sample data, it is trained by default training pattern, obtains this and specify logic to return Return model.

After obtaining above-mentioned multiple sample datas, you can carry out model training using the plurality of sample data.Implementing In, the default training pattern can include loss function model and initialization logic regression model, in that case, based on this Multiple sample datas, it is trained by default training pattern, obtains this and specify the specific implementation of Logic Regression Models to wrap Include the several steps in following (1)-(3):

(1) the plurality of sample data is quantified, obtains sample quantization vector.

In the specific implementation, can be quantified the plurality of sample data, for example, obtained sample quantization vector is X ={ xi, wherein i=1,2,3...n, the n is default positive integer, can be configured in advance by user, and for example, the n can be with It is arranged to 10.After the plurality of sample data is quantified, the sample quantization vector of n dimensions is obtained.

(2) by sample quantization vector input into the loss function model, and it is somebody's turn to do using gradient descent method by determining The minimum value of loss function model come determine estimate weight.

Wherein, the loss function model can be as shown in formula (1):

Wherein, yj∈ { 0,1 }, j=1,2, yjTwo tag along sort information are represented, for example, working as the yjWhen=1, classification letter is represented Cease to raise gesture, as the yjWhen=0, classification information is represented as upper oarsman's gesture.W is unknown assessment parameter.

Afterwards, L (w) is minimized by gradient descent method, when seeking L (w) minimum value, you can obtain estimation power Weight w.Wherein, during being minimized by gradient descent method to L (w), constantly it is trained based on the sample data, So that the L (w) is minimum, it that is to say, the process minimized by gradient descent method to L (w) is actually constantly instructed Experienced process.

(3) the estimation weight is inputted into the initialization logic regression model, obtains this and specify Logic Regression Models.

In the specific implementation, the initialization logic regression model can be as shown in formula (2) and (3), terminal can should After estimation weight w is brought into initialization logic regression model (2) and (3), you can obtain specifying Logic Regression Models such as formula (4) With formula (5) Suo Shi:

Wherein, P (Y=1 | x) and P (Y=0 | x) are represented raise and go up a stroke gesture probability corresponding to two kinds of gestures respectively.

Further, the terminal can store to the specified Logic Regression Models trained in advance, in order to follow-up Logic Regression Models can be specified by this, the touch signal triggered based on different gestures, the different gestures are identified.

It should also be noted that, only it is so that the terminal is themselves based on different gestures progress model trainings as an example, in reality here In the application scenarios of border, model training can also be carried out by other terminals with identical function, afterwards, be specified what is trained Logic Regression Models are moved in the terminal.

After terminal storage has above-mentioned specified Logic Regression Models, SS later can carry out gesture identification, can specifically wrap Following steps 203 are included to step 205.

Step 203:When detecting the slide triggered by multiple touch points in the designated area in screen, according to Sliding trace obtains touch signal.

In practical implementations, the designated area can be configured by user is self-defined according to the actual requirements, for example, this refers to Determine bottom-left quadrant, lower right region, upper left side region, upper right side region that region can be the screen etc., the application is real Example is applied not limit this.

Fig. 2 B are refer to, are illustrated here so that the designated area is the bottom-left quadrant 21 of screen as an example.It that is to say, when Terminal illustrates that user can be with when detecting the slide triggered by multiple touch points on the bottom-left quadrant 21 of the screen By the fringe region upward sliding of the back of the hand, in order to identify that the gesture raises gesture or upper oarsman's gesture, terminal root Touch signal is obtained according to sliding trace.

Wherein, the plurality of touch point can be the shape of the touching screen in multiple joints where the fringe region of the back of the hand of user Into touch point.For example, as shown in 22 in Fig. 2 C.

Step 204:Based on the touch signal, by specifying Logic Regression Models to determine first gesture probability and second gesture Probability, the first gesture probability refer to that current gesture is to raise the probability of gesture, and the second gesture probability refers to current hand Gesture is the probability of upper oarsman's gesture.

In the specific implementation, the touch signal can be quantified, obtaining quantifying vector, afterwards, terminal can will The quantization vector input arrived is into the specified Logic Regression Models shown in above-mentioned formula (4) and formula (5), to determine two kinds of hands Gesture probability corresponding to gesture, respectively first gesture probability P (Y=1 | x) and second gesture probability P (Y=0 | x).

Further, in practical implementations, due to the characteristics of this raises gesture and upper oarsman's gesture is respectively provided with upward sliding, because This, based on the touch signal, before determining first gesture probability and second gesture probability by specified Logic Regression Models, goes back May determine that whether current gesture is that this raises one kind in gesture and upper oarsman's gesture, be that is to say, judge the gesture whether be The gesture of upward sliding.

In the specific implementation, can based on sliding trace come judge the gesture whether be upward sliding gesture, for example, if The initial position of the sliding trace is located at the lower zone of screen, and end position is located at the upper area of screen, then can determined The gesture is the gesture of upward sliding.

Certainly, it is necessary to which explanation, is only to judge whether the gesture is upward sliding based on sliding trace with this here Gesture exemplified by illustrate, in another embodiment, other manner can also be used to judge the gesture whether for upward sliding Gesture, for example, it is also possible to be judged based on location variation, the embodiment of the present application is not limited this.

Step 205:Based on the first gesture probability and the second gesture probability, current gesture is identified.

In the specific implementation, based on the first gesture probability and the second gesture probability, current gesture is identified Specific implementation can include:The maximum gesture probability in the first gesture probability and the second gesture probability is determined, will be current Gesture identification be gesture corresponding to the maximum gesture probability.

It can be appreciated that gesture probability is bigger, illustrate the possibility that current gesture is gesture corresponding to the maximum gesture probability It is bigger.For example, if the first gesture probability is more than the second gesture probability, illustrate to determine current hand after above-mentioned identification Gesture is that the probability for raising gesture is more than the probability that current gesture is upper oarsman's gesture, therefore, can be by current gesture identification Raise gesture., whereas if the first gesture probability is less than the second gesture probability, illustrate to determine currently after above-mentioned identification Gesture be that the probability for raising gesture is less than the probability that current gesture is upper oarsman's gesture, therefore, current gesture can be known Wei not upper oarsman's gesture.

For example, when the first gesture probability is 70%, and the second gesture probability is 30%, it can be seen that current gesture To raise the probability of gesture more than the probability that current gesture is upper oarsman's gesture, therefore, current gesture identification can be raised Gesture, for example, this raises gesture as shown in Figure 2 D.
