Zoomable TV Interface Using Tag Tree Distance Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
TV user interfaces often require multiple clicks to access desired content, lacking an efficient middle ground between direct access and unclear targeting, impacting interaction efficiency.
Innovation Solution
A zoomable user interface is developed using a cascaded visual tag tree structure, where tags are assigned to video titles, forming a hierarchical relationship map and tag trees, minimizing total distance from the root node to optimize user navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional TV user interface is used, then users can access content through voice search or recommendations, but users need to click multiple times (dozen or more) to reach desired content, resulting in low interaction efficiency
Solution Approach 1:
The patent segments the content library into hierarchical categories using a tag tree structure. Users can navigate through layered categories (e.g., genre -> subgenre -> specific content) to access desired content more quickly, reducing the number of clicks needed compared to flat traditional interfaces.
Solution Approach 2:
The patent introduces a zoomable interface that adds a dimensional layer to content navigation. Users can zoom in on specific content items from a overview display, creating a multi-level navigation structure that reduces the depth of clicks needed to access content while maintaining comprehensive search capabilities.
2Ease of operation
If a zoomable user interface with tag tree structure is implemented, then user navigation efficiency is improved and total distance is minimized, but the system complexity increases due to tag assignment, relationship mapping, and tree construction processes
Solution Approach 1:
The patent performs preliminary actions by pre-assigning tags to video titles and pre-building the tag relationship map and tag tree structure. This preparation work is done in advance so that when users navigate the interface, they benefit from the optimized structure without experiencing the complexity of building it in real-time.
Solution Approach 2:
The patent uses tags as intermediary elements that bridge the gap between content metadata and user navigation. The tag tree structure acts as an intermediary layer between the raw content library and the user interface, simplifying navigation while managing system complexity through abstraction.
3Stability of the object's composition
If tags are assigned to video titles and a hierarchical tag relationship map is built, then a structured navigation system is created, but the processing time and computational resources required increase
Solution Approach 1:
The patent performs tag assignment and hierarchical structure construction as preliminary actions during content ingestion and indexing. Once the tag tree is built, it can be queried efficiently without reprocessing the entire structure, reducing processing time during user navigation operations.
Solution Approach 2:
The patent changes the parameter of organizing content from flat lists to hierarchical tag-based structures. This structural transformation enables more efficient navigation and reduces the effective processing time during user interactions by leveraging the pre-organized relationships between content items.

AI summary
A method for making a zoomable user interface for a television (TV) comprises the steps of: assigning a plurality of tags to a video title; collecting tags of a plurality of video titles of a video group; building a tag-relationship map based on a relationship of the tags, wherein the tag-relationship map represents a hierarchical structure of the tags in the video group; building a plurality of tag trees based on the hierarchical structure of the tags; calculating each total distance of each of the plurality of tag trees, wherein the total distance of the tag tree is a sum of distances from a root node to all nodes in the tag tree; and displaying the zoomable user interface having a minimum value of the total distance of the tag tree.
