Touchscreen Word Processing Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart devices with touch screens face inefficiencies in understanding user intentions for text editing operations, leading to slow response times and inconvenient text manipulation, such as copying and pasting, due to the need for specific user instructions.
Innovation Solution
Implementing multi-point touch technology to analyze user gestures by detecting the distance between touch points, triggering a word processing prompt menu when the distance falls below a preset threshold, allowing for rapid and intuitive copy, cut, paste, and scaling operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multi-point touch technology is implemented to detect touch point distance and trigger word processing operations automatically, then response efficiency and ease of operation are improved, but device complexity increases
Solution Approach 1:
The patent changes the detection parameter from simple touch presence to touch point distance measurement. By monitoring the distance parameter between multiple touch points and comparing it against a threshold, the system automatically triggers appropriate word processing operations, eliminating the need for separate instruction inputs and improving operational convenience.
2Productivity
If the system requires specific user instructions before performing text editing operations, then operation precision is maintained, but response time and productivity are reduced
Solution Approach 1:
The patent performs preliminary action by detecting and analyzing the user's touch gesture pattern before the actual word processing operation is needed. The system proactively determines the user's intent based on touch point distance and automatically prepares to execute the appropriate operation, eliminating the time loss associated with requiring separate instruction inputs.
3Speed
If the system triggers word processing operations based on touch point distance threshold, then response efficiency is improved, but measurement precision requirements increase
Solution Approach 1:
The patent establishes a distance threshold parameter that balances response speed and measurement precision. By setting an appropriate threshold value, the system can quickly determine whether to trigger word processing operations without requiring extremely high measurement precision, thus achieving fast response while maintaining acceptable accuracy.

AI summary
The present disclosure provides a wording processing method for smart device with touch screen, including following steps: when it is detected that the number of touch points on a touch screen is two, storing initial coordinates of the two touch points; when it is detected that two touch points disappear, determining whether a distance between final coordinates of the two touch points is less than a preset threshold; and when the distance between the final coordinates of the two touch points is less than the preset threshold, triggering a word processing prompt menu. When performing the word processing operation, the word processing device of the present disclosure analyzes the user's gesture by using the multi-point touch technology and obtains the purpose of the word editing operation from user, which facilitates the word processing operation and provide a more rapid response.
