Mobile Text Editing Controls for Precise Sub-Text Deletion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal text editing methods are inefficient due to inaccurate cursor positioning and repetitive manual deletion, which is time-consuming and difficult to execute accurately.
Innovation Solution
A method for editing text on mobile terminals that involves displaying a preset text deletion control on a preset side of the target text in response to a user input, allowing for selection and deletion of sub-text through joystick control, touch pressure, and slide inputs to facilitate precise and flexible text editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the traditional copy and paste method is used to obtain a part of a short message, then the entire short message can be copied, but the cursor positioning becomes inaccurate and time-consuming due to the small size of the cursor and repeated adjustments
Solution Approach 1:
The patent introduces a control object as an intermediary between the user and the text deletion operation. This control object, displayed at a first position relative to the target text, serves as a mediator that simplifies the interaction. When the user operates this control object, it automatically identifies and deletes the target sub-text without requiring precise manual cursor positioning, thus resolving the contradiction between positioning accuracy and editing time.
Solution Approach 2:
The control object automatically performs the function of identifying and deleting the target sub-text based on user operation. Instead of requiring the user to manually position the cursor and delete characters one by one, the system enables the control object to self-serve by automatically completing the text deletion task once activated, significantly reducing the time and effort required for text editing.
2Measurement precision
If the cursor is made small for precise positioning, then the positioning can be more accurate, but the cursor becomes difficult to locate and requires repeated adjustments
Solution Approach 1:
The patent segments the text editing function into two distinct components: a control object for initiating the deletion operation and a cursor for precise positioning. The control object is displayed separately at a first position, while the cursor operates at a second position. This segmentation allows the control object to be larger and easier to operate, while the cursor remains small for precise positioning when needed, resolving the contradiction between precision and ease of operation.
Solution Approach 2:
The control object acts as an intermediary that eliminates the need for users to directly manipulate the small cursor for text deletion. By operating the control object instead, users can initiate the deletion function without struggling to locate and position the small cursor, thereby improving ease of operation while maintaining the cursor's small size for precision when other operations are needed.
3Ease of operation
If manual deletion of each character is performed in sequence, then complete control over deletion is achieved, but the process becomes extremely time-consuming and repetitive
Solution Approach 1:
The patent implements preliminary action by having the control object pre-configured to identify and mark the target sub-text before the actual deletion occurs. When the user operates the control object, the system has already prepared the deletion target, allowing for rapid execution of the deletion operation. This eliminates the need for repetitive character-by-character deletion while maintaining precise control over what text is deleted, thereby improving productivity without sacrificing deletion control precision.
Solution Approach 2:
The control object enables self-service text deletion by automatically identifying and deleting the target sub-text once activated by the user. Instead of requiring manual character-by-character deletion, the system allows the control object to perform the entire deletion task autonomously, significantly improving text editing efficiency while maintaining user control through the intuitive operation of the control object.

AI summary
A method for editing text and a mobile terminal are provided. The method includes: receiving a first input of a user on target text; displaying a preset text deletion control on a first preset side of the target text in response to the first input; receiving a second input of the user on the text deletion control; and deleting, in response to the second input, target sub-text selected by the second input, where the target text includes the target sub-text.
