Gesture-Based Media Filtering on Touch-Sensitive Map Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media file management systems are inadequate for conveniently locating media files based on geographic location and other attributes, as they lack a suitable method for filtering and displaying media associated with specific geographic areas and timestamps.
Innovation Solution
An interactive media display system that uses a touch-sensitive display surface to receive gesture inputs defining geographic areas, filters media data based on metadata such as position data, and displays relevant media files on the surface, allowing users to access media associated with selected locations and times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current media file management systems organize media files according to folder name, file name, and date/time of creation, then media files can be stored systematically, but it becomes difficult to conveniently locate media files associated with specific geographic locations
Solution Approach 1:
The patent introduces a geographic dimension (latitude and longitude coordinates) to the traditional media file organization system. Instead of only organizing by folder name, file name, and date/time, the system now incorporates spatial information from GPS metadata, allowing users to locate media files by geographic location in addition to traditional attributes. This dimensional extension resolves the contradiction by enabling geographic-based search without fundamentally changing the underlying file management structure.
Solution Approach 2:
The patent uses a map interface as an intermediary between the user and the media file database. Users interact with the map by selecting geographic areas, and the system translates these visual selections into queries for media files with matching GPS coordinates. This intermediary layer simplifies the user experience compared to directly querying database fields, while maintaining efficient access to media files through the existing metadata structure.
2Loss of information
If no geographic location-based filtering is implemented, then the media file management system remains simple, but users cannot locate media files associated with particular geographic locations
Solution Approach 1:
The patent extracts geographic location information from the metadata of media files and presents it through a dedicated map interface. By separating the geographic data representation from the general file management interface, the system enables users to access and filter media by location without adding complexity to the entire file management system. The map interface serves as a specialized view that leverages existing GPS metadata without requiring changes to the core file storage and management infrastructure.
3Adaptability or versatility
If media files are organized only by traditional attributes (folder, file name, date), then the file management structure remains simple, but the system lacks the capability to filter and display media by geographic area and timestamp
Solution Approach 1:
The patent implements a multi-functional system where the map interface serves multiple purposes: displaying geographic locations, enabling area selection, filtering media files by location, and presenting results. This universal interface consolidates what could be multiple separate functions into a single cohesive interaction model, enhancing versatility without proportionally increasing operational complexity. The same map display that shows locations also serves as the selection mechanism for filtering.

AI summary
An interactive media display system is provided to display media associated with a selected geographic area based on a gesture input of user. The interactive media display system may include a touch-sensitive display surface configured to display a geographic map and receive a gesture input generated by a user on the touch-sensitive display surface while the geographic map is displayed, the gesture input defining a selected geographic area on the geographic map. The system may further include a controller configured, in response to the gesture input, to filter the media data based on position data to determine a filtered media data collection including media that are associated with the selected geographic area, and to command the touch-sensitive display surface to display the media in the filtered media data collection.
