The method for acquiring the historical sliding track specifically includes: the touch display screen of the terminal detects an on touch event operated by a finger of a user. And acquiring the track coordinates of the finger operation points of the user by using a getX and getY method of a Motion Event object through a system re-interface on touch Event.

Step S202, the terminal samples at least three points from a historical sliding track, obtains at least three coordinates corresponding to the three points, and determines an axis coordinate according to the at least three coordinates;
the implementation method of step S202 may specifically include: and calculating the center coordinate of the sliding track according to the three coordinates, wherein the center coordinate is the axis coordinate.
An example of actual calculations is described below.
Referring to fig. 2a, fig. 2a is a kth historical sliding trajectory graph acquired by the method provided in step S201, and at least three points of random sampling are assumed to be; A. b, C, obtaining the coordinates of A, B, C can be: (A) x,k ,A y,k )、(B x,k ,B y,k )、(C x,k ,C y,k ) (ii) a The product of the difference obtained by subtracting the square of the coordinate value of the point A from the square of the coordinate value of the point B and the difference of the y-axis coordinate of the point C and the point B is multiplied; the result of dividing the product by 2 times of the first product difference is the axis coordinate Ox, and the first product difference is equal to the difference between the first product of the difference between the x-axis coordinates of the points B and A multiplied by the difference between the y-axis coordinates of the points C and B and the second product of the difference between the x-axis coordinates of the points C and B multiplied by the difference between the y-axis coordinates of the points B and A. The axis coordinate Oy is equal to the result of dividing the second product difference by the first product difference, and the second product difference may be: and the difference between a third product obtained by multiplying the difference between the x-axis coordinate difference of the point B and the point A by the difference between the square of the coordinate of the point C and the square of the coordinate of the point B and a fourth product obtained by multiplying the difference between the x-axis coordinate difference of the point C and the point B by the square of the coordinate of the point B and the square of the coordinate of the point A.
The axis coordinate (O) can be calculated according to the following formula x ,O y )。
Of course, in practical applications, in order to improve the accuracy of the axis coordinate, the axis coordinate may be determined by calculating a plurality of historical sliding tracks, and assuming that the plurality of historical sliding tracks are n sliding tracks, the axis coordinate may be n sliding track metersThe calculated average value of n axis coordinates, specifically the axis coordinate (O) x ,O y ) The calculation method of (c) is as follows:
step S203, the terminal determines the one-handed operation type according to the position relationship between the axis coordinate and the historical sliding track.
The implementation method of step S203 may specifically include:
if the axis is positioned on the right side of the historical sliding track, determining that the single-hand operation type is right-hand operation;
and if the axis is positioned on the left side of the historical sliding track, determining that the single-hand operation type is left-hand operation.
The method for determining the type of the one-handed operation may specifically include:
if the historical sliding trajectory is 1, it can be determined in the following manner.
Such as O x -B x,k More than or equal to 0, determining the type of the one-hand operation as the right-hand operation, and otherwise, O x -B x,k If the operation type is less than 0, the single-hand operation type is determined to be left-right operation.
If the historical sliding trajectory is 1, it can be determined in the following manner.
Such as
Determining the type of one-handed operation as right-handed operation, and vice versa>
And determining the type of the one-hand operation as a left-right operation.
Certainly, in practical application, the coordinates of other points may be used instead of the coordinates of the point B, the coordinates of the point B in this embodiment are the coordinates of the middle point, and the determination of the type of one-handed operation using the coordinates of the point B can be more accurate, and in practical application, the coordinates of the point a or the point C may also be used for determination, or the average value of the coordinates of A, B, C may also be used for determination, and this embodiment is not limited to the specific manner of the determination.
For the basis of the judgment of the single-hand operation type, a large number of historical sliding tracks show that for 2 types of single-hand operation, the first type is left-hand operation, the second type is right-hand operation, the axis coordinate of the target object cannot be in the input interface area based on the holding habit of the target object and the historical sliding tracks, the axis coordinate can be obtained by analyzing massive historical sliding data, if the target object is positioned in the left-hand operation, the position of the sliding track coordinate relative to the axis is determined to be on the right side of the axis, and if the sliding track coordinate relative to the axis is positioned on the left side of the axis, the right-hand operation can be determined. Based on such an analysis, it is possible to determine which type of one-handed operation belongs by the refinement of step S203 described above.
The second embodiment of the application provides a method for determining and implementing a single-hand operation type, and the method supports implementation of the first embodiment.
