Apply the above-mentioned purpose of example, feature and advantage can be more obvious understandable, below in conjunction with the accompanying drawings to technical side in the embodiment of the present invention
Case is described in further detail.
First, a kind of gesture identification method provided by the invention is introduced.
Referring to Fig. 2, for the flow of a gesture identification method embodiment provided by the invention, handling process can specifically wrap
Include：
Step 201, receive the gesture that user is inputted by touch-screen；
In the step, when user contacts touch-screen by finger to be operated, touch-screen receives the hand of user's input
Gesture, start that the gesture is identified.
Step 202, the gesture is divided into multiple sampled points, obtains the contact surface of each sampled point and the touch-screen
Product.
In the embodiment of the present invention, not only according to finger, whether caused displacement reaches identification gesture institute on the touchscreen
Preset initial displacement threshold value, carry out gesture identification.In particular it is required that position is produced on the touchscreen further combined with user's finger
During shifting, the variation tendency of contact action, user gesture is identified when finger contacts with touch-screen.
Thus, the variation tendency of contact action when finger contacts with touch-screen need to such as be obtained, it is necessary first to divide gesture
For multiple sampled points, and further obtain the contact area of each sampled point and the touch-screen.
Step 203, by the mean exposure area of the multiple sampled point compared with preset contact area threshold value, and will
The contact area data of the multiple sampled point carry out curve fitting, according to comparative result and fitting result to identification gesture institute
Preset initial displacement threshold value is adjusted.
In the embodiment, the contact area threshold value of preset finger and touch screen, connecing for multiple sampled points and touch-screen is calculated
The average value of contacting surface product, and by the average value compared with preset contact area threshold value, to determine whether the average value is higher than
Or less than the preset contact area threshold value.Then, the contact area data of multiple sampled points are carried out curve fitting, to obtain hand
Refer to the variation tendency contacted with touch-screen.Finally, it is preset to identification gesture according to foregoing comparative result and fitting result
Initial displacement threshold value is adjusted.
The initial displacement threshold value is used to primarily determine that the gesture operation of user to be clicking operation or slide.The present invention
In embodiment, in specific identification process, can according to aforesaid plurality of sampled point and the average value of the contact area of touch-screen with
The comparative result of preset contact area threshold value, and curve-fitting results carry out the corresponding adjustment of initial displacement threshold value.
During specific implementation, the setting of initial displacement threshold value is empirical value, can have difference according to certain amount
Age, height, the crowd of finger size and operating habit are determined.When the finger displacement of user exceedes the displacement threshold value,
The operation that active user can be primarily determined that is slip；, can be tentatively true when the finger displacement of user is less than the displacement threshold value
The operation for determining active user is click.
For contact area threshold value, can be set and various integrated chips pair according to the processing attribute of different integrated chips
The contact area threshold value answered.
Step 204, according to the displacement threshold value after adjustment, the gesture of the user is identified.
In the embodiment of the present invention, the contact area threshold value of preset finger and touch screen, when touch-screen receives user's input
Gesture after, the gesture is divided into multiple sampled points, obtains the contact area of each sampled point and the touch-screen, by institute
The mean exposure area of multiple sampled points is stated compared with preset contact area threshold value, and by the contact of the multiple sampled point
Area data carries out curve fitting, to obtain the variation tendency that finger contacts with touch-screen, according to the variation tendency, to identifying hand
The preset initial displacement threshold value of gesture adjusts accordingly, and the problem of to prevent to user gesture wrong identification, improves and touches
Touch accuracy of the screen to user gesture identification.
In the embodiment of the present invention, the mean exposure area of the multiple sampled point and preset contact area threshold value are compared
Compared with according to comparative result to identifying that the preset initial displacement threshold value of gesture is adjusted, mainly including following form：
（1）When the mean exposure area of the multiple sampled point is less than preset contact area threshold value, and the multiple sampling
The contact area data of point are fitted to form of straight lines, then reduce the initial displacement threshold value.
In this kind of scheme, when the mean exposure area of multiple sampled points is less than preset contact area threshold value, then it can determine that
The touch area of user's finger and touch-screen is smaller, such as：According to the use habit of most of users, gesture is carried out using forefinger
Operation.Further, the contact area data of multiple sampled points are fitted, when fitting result is form of straight lines, then it represents that
User's finger uniform force application on the touchscreen, is easier to that the gesture is identified.It is thereby possible to reduce the initial bit of initial preset
Move threshold value so that quickly identify active user's gesture, improve identification sensitivity.
After preset initial displacement threshold value is reduced, you can active user's gesture is identified, specifically included：
（a）When the gesture is preset less than the displacement after reducing in caused displacement on the touch-screen, by the hand
Gesture is identified as clicking operation；
（b）When the gesture is preset higher than the displacement after reducing in caused displacement on the touch-screen, by the hand
Gesture is identified as slide.
（2）When the mean exposure area of the multiple sampled point is higher than preset contact area threshold value, and the multiple sampling
The contact area data of point are fitted to conic section form, then increase the initial displacement threshold value.
In this kind of scheme, when the mean exposure area of multiple sampled points is higher than preset contact area threshold value, then it can determine that
The touch area of user's finger and touch-screen is larger, such as：The thumb being of little use using most of users carries out gesture operation.Enter
One step, the contact area data of multiple sampled points are fitted, when fitting result is conic section form, then it represents that user
Finger exerts a force and uneven on the touchscreen, than less easily the gesture is identified.Therefore, initial preset can be increased
Initial displacement threshold value so that the identification more accurate and effective to active user's gesture.
After preset initial displacement threshold value is increased, you can active user's gesture is identified, specifically included：
（c）When the gesture is preset less than the displacement after increase in caused displacement on the touch-screen, by the hand
Gesture is identified as clicking operation；
（d）When the gesture is preset higher than the displacement after increase in caused displacement on the touch-screen, by the hand
Gesture is identified as slide.
For the ease of the understanding to technical solution of the present invention, above-mentioned technical proposal is carried out below by specific implementation
Detailed description.
Assuming that the initial displacement threshold values that touch-screen is set is 16 pixels（pixel）.
When user is clicked on or during slide on the touchscreen every time, touch-screen can all report a series of gesture
Sampled point, it is as follows：Down (0), Move (1), Move (2) ... Move (N-1), Move (N) and Up (N+1).Wherein, Down
(0) it is used for the starting point for representing user's finger contacts touch-screen, Up (N+1) is used to represent that user's finger finally contacts touch-screen
Terminating point, Move (1)~Move (N) are used to represent N number of sampled point during user's click or slide.Specifically, N
Value depend on touch-screen report dot frequency, frequency is higher, and N is smaller, and frequency is lower, and N is bigger, to report dot frequency as 120MHz
Exemplified by, N value is 5 or 6.
Judge whether pair with preset displacement is preset be adjusted when, it is necessary to reference to Down (0) and click on or sliding
N number of sampled point in dynamic operating process is judged.
Specifically, N number of sampled point corresponding contact respectively during Down (0) and click or slide is obtained
Area figures, calculate the average value of contact area numerical value corresponding to these sampled points, and by the average value and preset contact area
Threshold value is compared.Each touch-screen producer may be different to the value of preset contact area threshold definitions, below with preset contact
Area threshold illustrates for 100.
If mean exposure area is less than 100, and the curve approximation of these sampled points fitting is in linear function form, example
Such as：Form of straight lines y=k, as shown in Figure 3.Then this kind of situation shows, the contact area of active user's finger and touch-screen is smaller, by
This, current setting is used to determine that user to be click on operating or the displacement threshold value of slide is for the user, numerical value
It is bigger than normal.Therefore, it is necessary to which the displacement threshold value is reduced.
If mean exposure area is more than 100, and the curve approximation of these sampled points fitting is in quadratic function form, example
Such as：Parabolic, as shown in Figure 4.Then this kind of situation shows, the contact area of active user's finger and touch-screen is larger, by
This, current setting is used to determine that user to be click on operating or the displacement threshold value of slide is for the user, numerical value
It is less than normal.Therefore, it is necessary to which the displacement threshold value is increased.
During specific implementation, amplitude that displacement threshold value is specifically decreased or increased is empirical value.
The determination method for the amplitude that displacement threshold value is specifically decreased or increased is exemplified below.Such as：Utilize a touch
Screen dimensions are the mobile phone of 4.5 inch（Resolution ratio 960*540, picture element density 1.5）, allow what different crowds was clicked on and slided
Operation, the displacement that finger in click and slide occurs on the touchscreen count, when statistical result is found：For with
Finger and touch-screen contact area less crowd when forefinger is clicked on or slided, finger displacement generally in 6pixel or so,
The finger displacement is generally less than initial displacement threshold value, and during slide, finger displacement is more than 6pixel；For with thumb
Finger and touch-screen contact area larger crowd when being clicked on or being slided, finger displacement may in 20~24pixel or so,
The finger displacement is generally higher than initial displacement threshold value, and during slide, finger displacement is more than 24pixel.Thus, in order to carry
The accuracy that high touch-screen identifies to user gesture, the size of user's finger and the contact area of touch-screen can be combined, is adapted to
Property adjustment initial setting up displacement threshold value：When finger is smaller with touch-screen contact area in operation, initial displacement threshold value is subtracted
Small is 6pixel；When finger is larger with touch-screen contact area in operation, initial displacement threshold value is increased to 24pixel.
