Touchscreen File Selection via Enclosure Gesture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Selecting multiple files on a touchscreen terminal is inefficient, requiring users to tap on each file individually, which becomes cumbersome when dealing with numerous dispersed files.
Innovation Solution
A method where a terminal determines a selection area based on a user's touch track, allowing multiple files to be selected simultaneously by defining a selection area when the distance between the starting and ending points of the track is within a set distance, and selecting files within this area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users tap on each file individually to select multiple files, then each file can be selected accurately, but the operation becomes cumbersome and time-consuming when dealing with numerous dispersed files
Solution Approach 1:
The patent segments the file selection process into two distinct modes: individual file selection through tapping and multi-file selection through area enclosure. By dividing the selection methodology, users can choose the appropriate mode based on the number and distribution of files, thereby improving operational efficiency when dealing with multiple dispersed files.
Solution Approach 2:
The patent introduces a spatial dimension to file selection by allowing users to enclose multiple files within a drawn area on the touchscreen. This transforms the selection process from one-dimensional (sequential tapping) to two-dimensional (area enclosure), enabling simultaneous selection of multiple files regardless of their positions on the screen.
2Measurement precision
If users select files one by one, then precise selection is achieved, but the complexity of the selection process increases with the number of files
Solution Approach 1:
The patent creates a universal selection mechanism that handles both single file and multi-file selection through a unified area-based interface. The same drawing gesture works whether selecting one file or many, eliminating the need for different selection procedures and reducing process complexity while maintaining selection accuracy.
Solution Approach 2:
The patent introduces a visual boundary line as an intermediary element between the user's selection intent and the actual file selection. This boundary line provides real-time feedback during the drawing process, allowing users to adjust their selection area to achieve precise file selection while simplifying the overall process compared to sequential tapping.

AI summary
A file selection method and a terminal are disclosed. The file selection method, applied to a terminal with a touchscreen, includes obtaining, by the terminal, a touch track of a user on the terminal, determining, by the terminal, that an area bounded by the track is a selection area when a distance between a starting point of the track and an ending point of the track is less than or equal to a set distance, and selecting, by the terminal according to the determined selection area, a file within the selection area.
