Embodiment 1

[0059] see image 3 , the user is editing information:

[0060] At this time, the user slides from point A to point B. Assuming that the coordinates of A are (X1, Y1) and the coordinates of point B are (X2, Y2), the length of the track

[0061] L = ( X 2 - X 1 ) ( X 2 - X 1 ) + ( Y 2 - Y 1 ) ( Y 2 - Y 1 )

[0062] Unit direction parameter D

[0063] D = X 2 - ...

Embodiment 2

[0076] see Figure 4 , the user is editing information:

[0077] At this time, the user slides from point A to point B. Assuming that the coordinates of A are (X1, Y1) and the coordinates of point B are (X2, Y2), the length of the track

[0078] L = ( X 2 - X 1 ) ( X 2 - X 1 ) + ( Y 2 - Y 1 ) ( Y 2 - Y 1 )

Abstract

The invention is suitable for the technical field of cursor positioning, and provides a cursor positioning method. The method comprises the following steps: acquiring the position of a current cursor during information editing; monitoring the current gesture sliding track of a user in real time; calculating a sliding distance and a sliding direction according to the sliding track; acquiring the font size of a current editing interface; calculating the next position of the current cursor in combination with the sliding distance, the sliding direction and font size according to the position of the current cursor; controlling the cursor to move correspondingly according to the calculated next position of the cursor. Due to the adoption of the method, the problem of incapability of positioning the cursor accurately in a sliding process is solved, smoother operation feel is brought to the user, and the satisfaction of the user to a terminal is improved during text editing.

Description

technical field [0001] The invention belongs to the technical field of cursor positioning, and in particular relates to a cursor positioning method, system and touch device. Background technique [0002] With the popularity of large-screen mobile phones, touch has become the most mainstream way to manipulate mobile phones. Users can use the existing text input function to edit documents, text messages, etc., to meet the needs of users for mobile office. During the entire editing process, the user moves the cursor forward and backward to achieve positioning to realize the basic operations of adding, deleting, and modifying text. [0003] However, although the existing technical solutions can achieve editing of documents and short messages, there is a problem that the cursor cannot be positioned accurately. After roughly locating a certain line of text, the user can slide the finger to move the cursor back and forth, but the moving distance is uncontrollable and often exceed...
