Refer to Fig. 1, Fig. 1 is the process flow diagram of the dynamic correcting method of a kind of reference value data that the embodiment of the present invention provides.Wherein, the dynamic correcting method of reference value data that the embodiment of the present invention provides can be applied to touch screen terminal.Such as, common touch screen terminal can comprise touch screen computer, touch-screen notebook, touch screen telephone machine, touch-screen mobile phone, touch-screen media player (as MP3), touch-screen digital album (digital photo frame) and touch-screen camera etc.As shown in Figure 1, the dynamic correcting method of these reference value data can comprise the following steps:
101, after finger touch gestures type is on the touchscreen identified, the Historical baseline Value Data corresponding to this touch gestures type is revised to obtain current base Value Data; Wherein, the input data of this touch gestures type of current base Value Data convergence, and the scope of the permission variable quantity of current base Value Data is identical with the scope of the permission variable quantity of Historical baseline Value Data.
If each permission variable quantity in the scope of 102 described current base Value Datas and described permission variable quantity be valid data with value, be described current base Value Data by described historical baseline values Data Update, the reference value data after described renewal are that touch gestures identification is next time used.
In an embodiment, if each permission variable quantity in the scope of the described current base Value Data in step 102 and described permission variable quantity be valid data with value, be that described current base Value Data is specifically as follows by described historical baseline values Data Update: if the maximum permission variable quantity in the scope of described current base Value Data and described permission variable quantity and value, and minimum permission variable quantity in the scope of described current base Value Data and described permission variable quantity all fall in default Limit of J-validity with value, be described current base Value Data by described historical baseline values Data Update.
As the optional embodiment of one, the Historical baseline Value Data corresponding to this touch gestures type in step 101 is revised to obtain current base Value Data and is specifically as follows: the difference calculating the input data of this touch gestures type Historical baseline Value Data corresponding with this touch gestures type, this difference is as modifying factor E

In an embodiment, if each permission variable quantity in the scope of described current base Value Data and described permission variable quantity is not valid data with value, then can abandon described current base Value Data.
In sum, in the embodiment of the present invention, after finger touch gestures type is on the touchscreen identified, can revise to obtain and level off to the current base Value Data of input data of touch gestures by the Historical baseline Value Data corresponding to this touch gestures type, and the scope of the permission variable quantity of current base Value Data is identical with the scope of the permission variable quantity of Historical baseline Value Data; And then each permission variable quantity in the scope of permission variable quantity determining current base Value Data and described current base Value Data be valid data with value time, can be current base Value Data by historical baseline values Data Update, the reference value data after described renewal be that touch gestures identification is next time used.Visible, the embodiment of the present invention one can make auto modification by the Historical baseline Value Data corresponding to this touch gestures type according to the touch gestures of user habit, level off to the current base Value Data of touch gestures input data to obtain, thus the identification precision to user habit touch gestures can be improved.
And, in the embodiment of the present invention, if each permission variable quantity in the scope of described current base Value Data and described permission variable quantity be valid data with value, be then described current base Value Data by described historical baseline values Data Update, thus avoid the situation that occurs that reference value data infinitely raise or infinitely lower to a certain extent.
Refer to Fig. 2, Fig. 2 is the process flow diagram of the dynamic correcting method of the another kind of reference value data that the embodiment of the present invention provides.Wherein, the dynamic correcting method of the reference value data shown in Fig. 2 can be applied to various touch screen terminal.As shown in Figure 2, the dynamic correcting method of these reference value data can comprise the following steps:
201, touch screen terminal identification finger touch gestures type on the touchscreen.
Wherein, touch gestures type can include but not limited to long by, horizontal stroke, perpendicularly to draw, diagonally opposing corner draws and double-clicks.
Wherein, touch screen terminal identification finger touch gestures type on the touchscreen can adopt existing techniques in realizing.For example, suppose to identify that long is 0.7s by the reference value data of (i.e. gesture), it allows the scope of variable quantity can be [-0.1s ~ 0.1s], so when the duration (as 0.8s) that user contacts touch-screen falls in scope [0.6s ~ 0.8s], then the touch gestures that can identify user for long by.Again for example, suppose to identify that the reference value data of horizontal stroke (i.e. gesture) be paddling track and horizontal line angle are 0 °, it allows the scope of variable quantity can be [-10 ° ~ 10 °], so when user's paddling track on the touchscreen and horizontal line angle (as 6 °) fall in scope [-10 ° ~ 10 °], then the touch gestures that can identify user is horizontal stroke.
202, the Historical baseline Value Data that touch screen terminal is corresponding to the touch gestures type identified is revised to obtain current base Value Data; Wherein, the input data of this this touch gestures of present reference value data convergence, and the scope of the permission variable quantity of these present reference value data is identical with the scope of the permission variable quantity of Historical baseline Value Data.
In an embodiment, the Historical baseline Value Data that touch screen terminal is corresponding to touch gestures type is revised to obtain present reference value data correction value and can be comprised the following steps:
(1), touch screen terminal calculates the input data D of touch gestures type
nthe Historical baseline Value Data B corresponding with this touch gestures type
n-1difference, this difference is as modifying factor E
n, i.e. E
n=D
n-B
n-1.
Wherein, if touch screen terminal just dispatches from the factory, so Historical baseline Value Data B
n-1the empirical value that Ji Shi manufacturer pre-sets.
(2), touch screen terminal calculates modifying factor E

nlarger on the impact of current base Value Data, α is less, then Historical baseline Value Data B
n-1larger on the impact of current base Value Data.
(3), touch screen terminal calculates Historical baseline Value Data B corresponding to touch gestures type
n-1with product value sum, obtain current base Value Data B
n, i.e. B
n=B
n-1+ E
n* α.

n-1for paddling track and horizontal line angle equal 0 °, it allows variable quantity scope to be [-10 ° ~ 10 °], so as Historical baseline Value Data B
n-1be modified to B
n, and B
nwhen=5 °, B
nthe scope of permission variable quantity remain [-10 ° ~ 10 °].
203, touch screen terminal judge maximum permission variable quantity in the scope of current base Value Data and described permission variable quantity and value, and whether all the falling in default Limit of J-validity with value of minimum permission variable quantity in the scope of described current base Value Data and described permission variable quantity, if so, step 204 is performed; If not, then step 205 is performed.
For example, the Historical baseline Value Data B identifying horizontal stroke (i.e. gesture) is supposed
n-1for paddling track and horizontal line angle equal 0 °, and it allows the scope of variable quantity to be [-8 ° ~ 8 °], so as Historical baseline Value Data B
n-1be modified to B
n, and B
nwhen=5 °, so B
nthe scope of permission variable quantity remain [-8 ° ~ 8 °].And now current base Value Data B
npermission variable quantity maximum with it 8 ° be 13 ° with value, current base Value Data B
npermission variable quantity-8 ° minimum with it with value for-3 °.The embodiment of the present invention can preset a Limit of J-validity for each touch gestures, such as, preset a Limit of J-validity (-20 ° ~ 20 °), at current base Value Data B for horizontal stroke
npermission variable quantity maximum with it with value (as 13 °), and at current base Value Data B
npermission variable quantity minimum with it all fall into Limit of J-validity (-20 ° ~ 20 °) with value (-3 °) time, then current base Value Data B is described
neffectively, the touch gestures type of user can be considered to horizontal stroke; Otherwise, current base Value Data B is described
ninvalid, the touch gestures type of user can not be considered to horizontal stroke again, and touch screen terminal can abandon this present reference value data B
n, and continue to preserve Historical baseline Value Data B corresponding to touch gestures type
n-1.
204, historical baseline values Data Update is current base Value Data by touch screen terminal, and the reference value data after described renewal are that touch gestures identification is next time used.
205, touch screen terminal abandons current base Value Data, and continues to preserve Historical baseline Value Data corresponding to touch gestures type.
