Fig. 4 is a schematic flowchart of a data processing method according to an embodiment of the present application. As shown in fig. 4, the method includes the following steps S410-S440.
Step S410: and acquiring the coordinates of the touch point on the touch panel.
The touch point coordinates are coordinates indicating a touch position of the user on the touch panel. As shown in fig. 5, a plurality of touch sensors are distributed on a touch panel, and each touch sensor occupies a certain area. The distribution area of each touch sensor is subdivided, and the position on the touch panel can be represented by coordinates.
As shown in fig. 5, 8 × 8 touch sensors are distributed on the touch panel, and the horizontal and vertical directions of each touch sensor are divided into 4, so that the coordinates of point a in fig. 5 are (11, 11). In practical applications, the abscissa and the ordinate of each touch sensor can be divided into 128 or 256 parts according to the requirement of resolution. And when a touch action occurs, processing the data according to the data acquired by the touch sensor to obtain the coordinates of the touch point. The touch point coordinates may be a plurality of coordinates on the user touch trajectory.
Step S420: and judging whether the touch point coordinate is in a preset touch range.
The preset touch range can be a closed graph in the range of the touch panel. In one embodiment, the outline of the closed figure may be the same as the outline of the touch panel. The outline of the touch panel can be circular, oval, quadrilateral, etc.
As shown in fig. 6, a circular touch panel 600 is provided, and the predetermined touch range 610 is a circle having a center the same as the center of the circular touch panel 600 and a radius smaller than the radius of the circular touch panel 600. In this step, it is determined whether the coordinates of the touch point obtained in step S410 are within a preset touch range. When the touch point coordinate is not within the preset touch range, it is indicated that the touch point coordinate is at the edge touch position, and the method provided by the embodiment of the application can be continuously adopted to perform data processing of the edge touch position. When the touch point coordinate is located at point B in fig. 6, it is described that the touch point coordinate is within the preset touch range; when the touch point coordinate is located at point C in fig. 6, it is described that the touch point coordinate is not within the preset touch range.
Step S430: and if the touch point coordinate is not in a preset touch range, connecting the central point coordinate of the touch panel with the touch point coordinate to obtain a connecting line.
The coordinates of the center point of the touch panel refer to coordinates of the center position of the touch panel. According to the touch panels with different shapes, the coordinates of the center point of the touch panel can be determined in different ways. In one embodiment, for a circular touch panel, the center point coordinates are the center of a circle; for a rectangular touch panel, the center point coordinate is the intersection point of two diagonal lines.
And if the touch point coordinate is not in the preset touch range, connecting the central point coordinate of the touch panel with the touch point coordinate to obtain a connecting line. As shown in fig. 6, in an embodiment, the center coordinate of the circular touch panel 600 is E, and the center coordinate E and the touch point coordinate C are connected to obtain a connection line.
Step S440: and updating the coordinates of the touch points into the coordinates of the intersection points of the connecting lines and the contour lines of the touch range.
Because the contour line of the touch range is a smooth curve or a straight line, in this step, the coordinates of the touch points are updated to the coordinates of the intersection of the connecting line and the contour line of the touch range, that is, the coordinates of the touch points are all updated to one point on the contour line of the touch range. In fig. 6, the touch point coordinate C is updated to the intersection point coordinate F. Because the contour line of the touch control range is a smooth curve or a straight line, the coordinate of the touch control point is updated to the intersection point coordinate of the connecting line and the contour line of the touch control range, so that the touch control track is conveniently updated to a curve along the contour line of the touch control range in the subsequent process, and the smooth effect of the touch control track of the edge touch control position is achieved.
According to the technical scheme provided by the embodiment of the application, whether the touch point coordinate is in the preset touch range or not is judged by acquiring the touch point coordinate on the touch panel, if the touch point coordinate is not in the preset touch range, the central point coordinate of the touch panel and the touch point coordinate are connected to obtain the connecting line, the touch point coordinate is updated to the intersection point coordinate of the connecting line and the contour line of the touch range, the coordinate correction of the edge touch position is realized, and therefore the subsequent smooth effect of the touch track of the edge touch position is achieved conveniently.
In an embodiment, the step S410 may include: acquiring touch capacitance data on the touch panel; and preprocessing the touch capacitance data to obtain the touch point coordinates.
The touch capacitance data refers to capacitance data directly acquired by the touch sensor and can indicate touch behaviors. When a touch action occurs at a certain position, capacitance data collected by the touch sensor at the position can be obviously changed. Touch control capacitance data are preprocessed, and touch control point coordinates can be obtained.
In an embodiment, the touch capacitance data is preprocessed by performing data processing processes such as filtering, edge calculation, and coordinate reporting to obtain the coordinates of the touch point.
On the basis of the above embodiment, the method provided by the embodiment of the present application further includes:
and performing edge judgment and coordinate updating processing on each touch point coordinate on the touch track to obtain an edge smooth touch track.
For the touch tracks at the edge touch positions, due to the uneven distribution of the touch capacitance data, the touch tracks are often jagged, bent, and the like. The edge judgment and coordinate updating processing operations provided by the above embodiment are performed for each touch point coordinate on the touch track, so that each touch point coordinate on the touch track is updated to be the intersection point coordinate of the connecting line and the contour line of the preset touch range. And obtaining an edge smooth touch track according to all the updated touch point coordinates. At this time, the updated touch track is a smooth curve along the preset touch range contour line, so that the problems of sawtooth, bending and the like of the previous edge touch track are solved.
In one embodiment, the touch panel is a circular panel with a radius R, and the predetermined touch range is a circle with a radius R, where R >0, and R < R; as shown in fig. 7, the step S420 of determining whether the touch point coordinate is within the predetermined touch range may include the following steps S710 to S730.
Step S710: and calculating the coordinates of the central point of the touch panel.
In this step, the coordinates of the center point of the touch panel may be calculated according to the geometric features of the circular panel. In an embodiment, the coordinates of the center point of the touch panel may be calculated according to the maximum value of the abscissa and the maximum value of the ordinate of the touch panel. In the rectangular coordinate system, let the coordinate of the center point of the touch panel be P0＝(x0，y0) Wherein x is0Is the abscissa, y0Is the ordinate. The maximum value of the abscissa of the touch panel is PosX _ Max, the maximum value of the ordinate is PosY _ Max, and then x is0＝PosX_Max/2，y0The center point coordinate of the touch panel may be represented as P ═ PosY _ Max/20＝(PosX_Max/2，PosY_Max/2)。
Step S720: and calculating the Euclidean distance between the coordinate of the touch point and the coordinate of the central point.
Let the coordinate of the touch point be P1Touch point coordinate P if (PosX, PosY)1Coordinate with the center point P0The Euclidean distance D between can be expressed as
Step S730: if the Euclidean distance is larger than r, indicating that the touch point coordinate is not in a preset touch range; otherwise, indicating that the touch point coordinate is in a preset touch range.
From the geometric characteristics of the circle, it can be derived that D is the time when D is>r, indicating coordinate P of touch point1The touch control panel is not in a preset touch control range, namely is in the edge position of the touch control panel; when in useWhen D is less than or equal to r, indicating the coordinate P of the touch point1And the touch screen is in a preset touch range.
In an embodiment, before step S440, the method further includes: and calculating the intersection point coordinates of the connecting line and the contour line of the touch range.
When the touch panel is a circular panel with a radius R and the predetermined touch range is a circle with a radius R, as shown in fig. 8, calculating the coordinates of the intersection point of the connecting line and the contour line of the touch range may include the following steps S810 to S840.
Step S810: and calculating the deflection angle of the connecting line relative to the coordinate axis.
As shown in FIG. 9, the abscissa and ordinate of the rectangular coordinate system are positive to the left and positive to the bottom, respectively, and the deflection angle θ of the connecting line with respect to the abscissa can be expressed as
Step S820: subtracting r from the Euclidean distance, and recording the result as delta D. I.e., Δ D-r.
Step S830: and calculating the mapping distance of the delta D on the coordinate axis according to the deflection angle.
From the deflection angle θ, the mapping distance of Δ D on the abscissa axis can be calculated as
ΔDx＝ΔD·cosθ
Likewise, the mapping distance of Δ D on the ordinate can be calculated as
ΔDy＝ΔD·sinθ
Step S840: and calculating the coordinates of the intersection points according to the mapping distance and the coordinates of the touch points.
According to the mapping distance Delta DxAnd Δ DyAnd touch point coordinates P1(PosX, PosY), the intersection coordinates P can be obtained2＝(PosX+ΔDx，PosY+ΔDy)。
After that, the touch point coordinate P is determined1Updated to the intersection point coordinate P3Thus, the touch point sitting at the edge touch position is completedThe subject data processing procedure.
