Wherein the mode of the touch action comprises writing or erasing; the generation type of the touch action corresponds to the mode of the touch action one by one.
The touch action generation type in the touch equipment corresponds to the touch action mode one by one, namely the electromagnetic pen, the finger or the palm only corresponds to one touch action mode in the current operation process, so that the touch action mode can be determined based on the touch action generation type.
In the touch device, a mode of a corresponding touch action is set in advance for a generation type of the touch action. For example, four modes are provided in the touch device: (1) the mode of the touch action corresponding to the electromagnetic pen is writing, and the mode of the touch action corresponding to the finger is erasing; (2) the mode of the touch action corresponding to the electromagnetic pen is writing, the mode of the touch action corresponding to the fingers is writing, and the mode of the touch action corresponding to the palm is erasing; (3) the mode of the touch action corresponding to the fingers is writing, and the mode of the touch action corresponding to the palm is book wiping; (4) the touch action mode corresponding to the electromagnetic pen is writing, the touch action mode corresponding to the finger is operation (translation, magnification, reduction, rotation, selection, copy, deletion and the like), and the touch action mode corresponding to the palm is erasing.
Because the capacitive screen can respond to the operation of fingers and palms, and the electromagnetic screen can respond to the operation of the electromagnetic pen.

An embodiment of the present invention further provides a method for processing touch data, as shown in fig. 2, the method includes:
and S21, acquiring touch information.
The touch information comprises a touch identification number, coordinates of a touch point and a generation type of a touch action; the touch identification numbers correspond to the touch actions one by one, and each touch action forms a plurality of touch points; the type of generation of the touch action includes at least one of an electromagnetic pen, a finger, or a palm. Please refer to S11 in fig. 1, which is not described herein again.

And forming a plurality of touch points in each touch action, forming a first touch point from the pressing of the touch screen, and sequentially extracting the coordinates of two adjacent touch points to perform subsequent fitting of the touch line. For example, the touch identification number a1 has corresponding touch points d1, d2, d3, … …, and dn, and the coordinates of each touch point are sequentially extracted, and the coordinates of two adjacent touch points are used to perform subsequent touch line fitting.
And S232, forming a touch line by using the extracted coordinates of the two adjacent touch points.
And taking two adjacent touch points as a group, and fitting the touch lines. For example, (d1, d2), (d2, d3), (d2, d3), … …, (dn-1, dn), fitting of a touch line is performed using the coordinates of two touch points in each group. The fitted touch line strip may be the same line strip as the canvas background to cover the line of the erased area.
The method specifically comprises the following steps:
(1) and judging whether the coordinates of the two adjacent touch points are the same.
When the coordinates of two adjacent touch points are the same, indicating that one point is formed at this time, S231 is performed again; and (3) when the coordinates of the two adjacent touch points are not the same, executing the step (2).
(2) When the coordinates of two adjacent touch points are different, fitting a touch line between the two adjacent touch points by using an interpolation method; wherein the color of the touch line strip is the canvas background.
A plurality of coordinate points are formed between two adjacent touch points by utilizing an interpolation method, so that a touch line is fitted based on the coordinate points, and the fitting precision of the line is improved.
It should be noted that the erasing in this embodiment may also be implemented in other manners, and only needs to be implemented by using the touch action mode, the touch identification number, and the coordinates of the touch point, which all belong to the protection scope of the present invention.
