Hierarchical Media File Interface for Small Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable digital devices with small displays face challenges in efficiently browsing and accessing large volumes of media files due to limited screen size, making it difficult for users to locate specific media items without extensive file display or categorization.
Innovation Solution
A user interface application utilizing a hierarchical display of media files, allowing users to browse through levels and categories, with an easily activated search function based on metadata and user-stored information, presenting search results in a user-friendly manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If media files are displayed in full detail on the screen, then file content identification is improved, but display size requirements increase making it unsuitable for portable devices
Solution Approach 1:
The patent segments media file information into hierarchical levels: first-level icons representing media files, second-level icons representing sub-files or related items, and metadata panels. This segmentation allows comprehensive information display through multiple interaction steps rather than requiring all information to be visible simultaneously, resolving the contradiction between complete information display and limited screen area.
Solution Approach 2:
The patent introduces temporal and spatial dimensions to information display by implementing multi-level hierarchical navigation. Instead of displaying all information in a single spatial plane, the system organizes information across multiple levels (first-level icons, second-level icons, metadata panels) that are accessed sequentially, effectively adding a temporal dimension to the display architecture.
2Quantity of substance
If all media files are stored on portable devices, then storage capacity utilization is improved, but file location and access efficiency deteriorates due to large volume of files
Solution Approach 1:
The patent implements preliminary organization of media files into hierarchical structures with first-level icons representing parent files and second-level icons representing sub-files or related items. This pre-organization allows users to navigate to specific files through systematic hierarchical paths rather than searching through all stored files, significantly reducing file location time while maintaining high storage capacity utilization.
Solution Approach 2:
The patent introduces hierarchical icon structures as intermediaries between the user and the actual media files. First-level icons serve as intermediaries that represent groups or parent files, and second-level icons serve as intermediaries that represent specific sub-files. This intermediary layer systematizes file access paths and reduces the time required to locate specific files among large volumes of stored media.
3Device complexity
If conventional file access applications are used on small displays, then implementation simplicity is maintained, but user ability to locate and access media files deteriorates
Solution Approach 1:
The patent segments the file access interface into hierarchical levels with first-level icons for parent files and second-level icons for sub-files. This segmentation creates a systematic navigation structure that is specifically adapted for small displays, allowing users to locate and access media files efficiently through structured hierarchical paths rather than attempting to display all files simultaneously.
4Productivity
If hierarchical display structure is implemented, then browsing efficiency is improved, but interface complexity increases
Solution Approach 1:
The patent implements a segmented hierarchical display where first-level icons represent parent media files and second-level icons represent sub-files or related items. This segmentation organizes complex information into manageable hierarchical units, improving browsing efficiency by allowing systematic navigation through organized structures rather than unstructured file lists.
Solution Approach 2:
The patent adds hierarchical depth as an additional dimension to the interface structure, organizing files across multiple levels (first-level icons, second-level icons, metadata panels). While this increases structural complexity, it dramatically improves browsing efficiency by providing systematic navigation paths and reducing the cognitive load required to locate specific files among large volumes of media.
Data Source
AI summary
A media management user-interface (UI) application that provides access to media items and media files and provides browsing and search capabilities for locating media items within media files. The UI application may rely on a hierarchical display of various levels or categories of media files and, as such, the application is uniquely suited for portable digital devices having small displays. The hierarchal display of media file levels allows the user to easily browse through levels to identify a desired media file and to locate and display a desired media item. In addition, the UI application may provide for an easily activated search function that provides for keyword searches to be performed based on information that has been associated with media files and media items.
