Background technique

With the development of computer technology and Internet technology, and the application of cloud technology, mobile terminals with touch screens are gradually popularizing in the fields of life, entertainment and office, carrying more and more text input and editing tasks. With the continuous maturity of multi-touch screen technology, touch operation has become the main operation mode. Touch screen devices can provide on-screen buttons to replace physical mice and keyboards. The on-screen buttons are customizable and can assign specific functions to the on-screen buttons; users can control and/or activate objects on the screen by touching, tapping, and dragging. Manipulate the target object directly. Therefore, when a lot of content is displayed on the screen, the touch sensitivity of the touch screen allows the user to perform operations on the content in an intuitive manner.

At present, touch screen terminals re-edit the input text by adding function buttons, increasing button density, popping up option boxes, or menu systems. During the editing process, the movement of the cursor is an essential step. However, due to the small screen size of the mobile touch screen device, especially in the text editing page, the text content display is small, and there are many operations on the text, and it is easy to cause errors by tapping the screen button in a small space. Tapping causes misoperation.

Touch screen cursor positioning is not as precise as mouse positioning. Typically, when the user finds missing content after entering a paragraph of text, the user must first move the cursor to the target insertion point, and then begin to input the missing text. In this process, the cursor positioning is more inaccurate due to the occlusion of the screen by the finger; the user must activate the corresponding function according to the step sequence and menu level set by the system, which increases the user's memory burden and forces the user to operate the steps; and, insert or When moving text, the touch screen does not provide sufficient feedback to the user to prompt whether the user's own operation behavior is recognized. The above-mentioned various shortcomings directly lead to inconvenient operation of the existing text editing method on the touch screen interface, resulting in low efficiency of text editing.
