Smartphone File Batch Selection via Touch Screen Drag Trajectory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a convenient and efficient method for batch processing files on smartphones using touch screens, which is necessary due to the increasing number of files and applications on mobile devices.
Innovation Solution
A method and smartphone implementation that enables file batch selection and processing through a sliding track of a finger or touchpen on the touch screen, allowing users to select files and folders by detecting point coordinates and performing operations like 'copy', 'cut', 'delete', and 'deselect' on all selected items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional touch screen operations are used for file selection, then the device maintains simple operation interface, but the file processing efficiency is low and time-consuming
Solution Approach 1:
The file selection process is segmented into distinct phases: entering selection mode, performing the drag operation to define selection range, and executing batch operations. This segmentation allows for more efficient file selection by enabling users to select multiple files through a single drag gesture rather than tapping each file individually
Solution Approach 2:
The system performs preliminary actions by automatically detecting and selecting files that fall within the drag trajectory before the user confirms the operation. This preliminary selection eliminates the need for users to manually select each file, thereby improving productivity and reducing the time required for file processing
2Productivity
If batch file selection functionality is added to touch screen, then file processing capability is improved, but the operation complexity increases
Solution Approach 1:
The system provides self-service by automatically detecting files along the drag trajectory and selecting them without requiring additional user input. The system handles the complexity of batch selection internally while maintaining a simple user interface, thus improving productivity without significantly increasing operational complexity
Solution Approach 2:
Multiple file selection operations are merged into a single drag gesture. Instead of requiring separate selection actions for each file, the system combines the selection of multiple files into one continuous motion, improving batch processing capability while keeping the operation simple
3Measurement precision
If file selection is based on drag trajectory detection, then selection accuracy is improved, but the system complexity increases
Solution Approach 1:
The patent replaces complex mechanical or manual selection methods with a digital coordinate detection and comparison system. By using software-based trajectory analysis to detect which files intersect with the drag path, the system achieves high selection accuracy while avoiding the need for complex hardware modifications

AI summary
A method for quickly operating files of a smart phone includes: the smart phone starting a file batch selection function according to an operation of a user; in a state that the file batch selection function is started, the smart phone selecting files and/or folders in corresponding positions according to a sliding track of a finger or an operation rod on a touch screen; and the smart phone performing an operation selected by the user on all selected files and/or folders. A smart phone includes: a touch screen and a file processor, wherein the file processor includes a batch selection on-off module, a file batch selection module and a file batch operation module. In the example of the present invention, the files are operated conveniently and quickly by using the touch screen of the smart phone, which has a significant effect in processing a large number of files.
