Interactive File Preview System Using Plug-in Mediators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data processing systems lack the ability to efficiently search for metadata across various applications, limiting the user's capability to find specific files based on metadata attributes, and do not provide interactive previews of file content without launching the application that created the file.
Innovation Solution
A method is introduced to display dynamic icons representing files in a graphical user interface, which include predefined decorations and allow interactive previews of file content without launching the creator application, using a background process and plug-ins to manage metadata and provide user interface controls for manipulating the preview, such as paging through documents or playing videos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a user launches the creator application to view file content, then the user can access detailed file information, but the search efficiency and user experience deteriorate due to the need to open multiple applications
Solution Approach 1:
The patent creates a preview copy of the file content that can be displayed within the file manager interface without launching the original application. The preview generator extracts and renders a simplified version of the file content (such as text, images, or video frames) directly in the icon or adjacent area, allowing users to view file contents quickly without opening the creator application.
Solution Approach 2:
The patent introduces a preview generator as an intermediary component between the file manager and the creator application. This mediator extracts preview data from files and presents it within the file manager interface, eliminating the need for users to launch the original application while still providing access to file content information.
2Ease of operation
If the system searches only through basic file parameters (name, type, date), then the search process is simple, but the search capability deteriorates because it cannot find files based on metadata or content attributes
Solution Approach 1:
The patent implements a universal search mechanism that can handle multiple search criteria simultaneously - including basic file parameters (name, type, date) and advanced metadata attributes (author, subject, keywords, content). The search function is designed to work across different file types and applications through a common interface, providing both simplicity and versatility.
Solution Approach 2:
The system automatically extracts and indexes metadata from files without requiring user intervention. The preview generator and search system work together to automatically read file metadata and content attributes, making them available for search operations. This self-service approach maintains ease of operation while significantly enhancing search capability.
3Ease of operation
If the system provides interactive preview controls within the icon, then the user experience improves, but the device complexity increases due to additional interface elements and processing requirements
Solution Approach 1:
The patent applies local quality by providing enhanced interactive controls only where needed - specifically within or adjacent to the file icon area where users naturally interact with file representations. The preview controls (such as play buttons for video, pagination for documents) are localized to the icon region rather than requiring a full application window, reducing overall interface complexity while improving user experience at the point of interaction.
Data Source
AI summary
User interfaces for browsing and/or searching are described. In some embodiments, the metadata of a file includes a field having an indicator to indicate whether a preview of the content of the file is available. If the preview is available, then a plug-in associated with the creator application of the file is executed to present the preview within the icon. Furthermore, if the preview is interactive according to the metadata, then various user interface control may be generated to allow users to manipulate the presentation of the preview. Other embodiments are also described, and computer readable media and apparatuses are also described.
