NFC Tag Menu System for Smart Poster Content Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 'single tap—single action' methodology for NFC tags complicates building rich content for smart posters, as there is little context for multiple tags within the same smart poster, making it difficult for users to access and interact with multiple tags effectively.
Innovation Solution
An intermediate layer is introduced that includes references or links to all other tags within the same smart poster, allowing users to access all tags within a set through a single tag, using a computer-implemented method and backend server that maintains information about sets of tags and returns content information to the user device for display in a user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple NFC tags are embedded in a smart poster to provide rich content, then the content richness is improved, but the ease of operation deteriorates because users cannot easily access all tags
Solution Approach 1:
The patent introduces a menu system as an intermediary layer between the NFC tags and the user. When a user taps any tag in the smart poster, a menu is displayed showing all available tags. This menu mediates the interaction by providing a centralized access point that lists all tags, allowing users to navigate to any tag's content without needing to physically locate and tap each tag individually. This resolves the contradiction by maintaining multiple tags for content richness while simplifying user access through the menu interface.
2Adaptability or versatility
If multiple NFC tags are embedded in a smart poster, then the functionality is improved, but the device complexity increases due to multiple tags needing to be managed
Solution Approach 1:
The patent merges the management of multiple NFC tags into a single unified system. Instead of treating each tag as an independent entity that requires separate management, the system combines all tags under a common menu structure. The menu aggregates information from all tags and provides a single point of control, allowing users to access any tag's functionality through one interface. This merging approach maintains the versatility of multiple tags while reducing the perceived complexity by presenting a unified, simplified interaction model.
3Ease of operation
If the single tap—single action methodology is used for NFC tags, then the ease of operation is improved, but the loss of information increases because context for multiple tags is lost
Solution Approach 1:
The patent adds a new dimension to the single tap interaction by introducing a menu layer. Instead of the traditional single tap leading directly to a single action, the first tap now opens a menu dimension that displays all available tags. From this menu, users can select which tag's content to access. This dimensional addition preserves the simplicity of single tap operation while recovering the lost context by presenting information about all tags in the poster, allowing users to make informed decisions about which content to access.
Data Source
AI summary
A computer implemented method including: maintaining, in a storage, information about one or more sets of tags, wherein each set of tags comprises two or more tags, receiving, from a user device, a request for content relating to a certain tag, wherein the request comprises an identifier, identifying, on the basis of the identifier and the information maintained in the storage, a set of tags that comprises said certain tag, and returning, to the user device, information about content relating to said certain tag and information about content relating to at least one other tag belonging to said identified set of tags.
