Touch Screen Playlist Folder Sorting via Path Gestures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack an efficient method for dynamically managing and displaying playlists on touch screens, particularly in responding to multi-touch gestures and maintaining user interaction with hierarchical folder structures.
Innovation Solution
The electronic device employs a control unit that detects and responds to various touch gestures, such as continuous movement, flick, drag, and rotate, to generate new folder names, sort folders based on storage paths, and abbreviate storage paths, providing visual, auditory, and haptic feedback while allowing users to rearrange and interact with playlist structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the playlist displays detailed hierarchical folder structures with full storage paths, then the information completeness is improved, but the screen space utilization and ease of operation deteriorate due to the limited display area and complex navigation
Solution Approach 1:
The display structure dynamically adjusts between detailed and abbreviated views based on user interaction. When a folder is selected, its storage path transitions from a static display element to a draggable, movable element that can be reassigned to different playlist positions, enabling flexible reorganization without permanent structural changes
Solution Approach 2:
The storage path information is segmented into hierarchical components (folders and subfolders) that can be independently manipulated. Each folder name in the path can be individually dragged and dropped to create new folder assignments, allowing granular control over playlist organization while maintaining information completeness
2Ease of operation
If the system allows free dragging and dropping of folder elements to rearrange playlists, then the ease of operation is improved, but the device complexity increases due to multiple gesture recognition requirements
Solution Approach 1:
The touch screen interface uses universal drag-and-drop gestures that serve multiple functions: selecting folders, repositioning them in the playlist, and assigning them to different parent folders. The same basic gesture mechanism handles both navigation and reorganization tasks, reducing the need for separate control mechanisms despite the increased operational capabilities
3Measurement precision
If the electronic device displays full storage paths for all folders in the playlist, then the measurement precision of folder identification is improved, but the area of display and readability deteriorate due to screen space constraints
Solution Approach 1:
The display dynamically adapts its level of detail based on the interaction state. During normal viewing, abbreviated folder names are displayed to maximize screen space utilization. When a folder is selected or being manipulated, the full storage path becomes visible to ensure precise identification, creating a dynamic balance between readability and precision

AI summary
A user interface method employed by an electronic device displays a folder playlist playable by an application, on a touch screen and detects a touch selecting one folder in the displayed folder playlist. A touch gesture is detected comprising a continuous movement of a touch and performs a sorting operation using a name representation of a storage path of a folder where the touch is detected, in response to the continuous movement of the detected touch gesture.
