[0114] Based on the first embodiment, the second embodiment of the writing method based on the touch screen of the present invention is proposed. In this embodiment, before step S21, it also includes:

[0115] Step S23, when the writing operation is detected, determine whether the currently collected current touch point is the starting point;

[0116] Step S24, if the current touch point is the starting point, then obtain preset ellipse parameters;

[0117] Step S25, drawing an ellipse based on the preset ellipse parameters with the starting point as the center point.

[0118] In this embodiment, the starting point is the first point collected when the object just touches the screen during the user's writing operation. When monitoring the user's writing operation, it is judged whether the current touch point collected is the starting point. The current touch point is the starting point, then obtain the preset ellipse parameters (including the length of the major axis and the ...

Abstract

The invention discloses a writing method based on a touch screen, and the method comprises the following steps: monitoring a writing operation of a user on the touch screen, obtaining coordinate dataof a touch point when an object slides on the touch screen when the writing operation is monitored, and enabling the faster the sliding of the object on the touch screen is, the larger the distance between the touch points is; calculating a first graphic parameter corresponding to the touch point based on the coordinate data, and smoothing a track of the touch point based on the coordinate data toobtain smooth point data of a smooth point in the track; and calculating a second graphic parameter corresponding to the smooth point based on the first graphic parameter, and drawing a preset graphbased on the first graphic parameter, the second graphic parameter, the coordinate data and the smooth point data to generate a writing track. The invention further discloses a writing device and equipment based on the touch screen and a readable storage medium. The writing effect is improved.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a writing method, device, equipment and readable storage medium based on a touch screen. Background technique [0002] With the rapid development of electronic information technology, handwriting is more and more widely used. At present, when the terminal determines the handwriting, it can first collect multiple touch points on the touch screen, and then use each two corresponding touch points in the multiple touch points. Adjacent touch points are connected by a straight line with a fixed width to obtain a line between every two adjacent touch points, and then, the terminal can draw a line between every two adjacent touch points to obtain handwriting on the touch screen. However, in the process of determining the handwriting, since every two adjacent touch points are simply connected by a straight line with a fixed width, the thickness of the strokes in the final handwrit...
