2D Grid Content Navigation for TV Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in navigating and finding relevant content items in large databases due to the lack of a clear overview when browsing by similarity or relatedness, leading to increased time spent browsing and energy consumption, especially on devices with limited interaction paradigms like TV sets.
Innovation Solution
A method of displaying content items in a two-dimensional grid based on their relatedness values, where the highest relatedness item is centered in each column, allowing easy navigation and discovery of both closely and less closely related items, reducing the need for linear scrolling and processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content items are displayed in a linear list format, then the device complexity is low, but the ease of operation deteriorates due to increased browsing time and difficulty in finding relevant content
Solution Approach 1:
The patent transforms the traditional linear one-dimensional content list into a two-dimensional grid layout. Content items are arranged in rows and columns, with the selected content item positioned at the center and related items distributed across the grid based on their relatedness scores. This dimensional change allows users to perceive relationships between content items more intuitively and navigate through the database more efficiently, resolving the contradiction between ease of navigation and display structure complexity.
2Ease of operation
If more content items are displayed to provide better overview, then the ease of operation improves, but the loss of time increases due to higher processing load and data transmission requirements
Solution Approach 1:
The patent extracts and displays only the most relevant content items based on calculated relatedness scores. Instead of displaying all available content items or requiring users to browse through large datasets, the system identifies and presents the top-N most related items in the two-dimensional grid. This extraction approach provides a quality overview of relevant content while minimizing processing time and data transmission requirements.
3Productivity
If content items are arranged by highest relatedness first in a linear list, then the productivity of finding relevant content improves, but the ease of operation deteriorates due to lack of visual structure and overview
Solution Approach 1:
The patent arranges content items in a two-dimensional grid where the selected item is at the center and related items are positioned in surrounding cells based on their relatedness scores. This spatial arrangement provides both the productivity of ranked ordering (most related items are prominently positioned) and the visual overview quality of a structured layout (items are distributed across rows and columns, allowing users to perceive relationships at a glance). The grid structure enables users to quickly scan and understand content relationships without linear scrolling.

AI summary
A method of operating an apparatus for displaying content items on a display, a corresponding computer program for operating an apparatus and an apparatus for displaying content items on a display that is arranged for being coupled to the apparatus are provided. In particular, an apparatus is configured to display a plurality of content items in a two-dimensional grid in dependence of a respective relatedness between a selected content item and one of the content items to be displayed. The selected content item is positioned at a center of the display and the related content items are displayed such that associated relatedness values decrease both in left, right, up and down direction with respect to the center position. A user terminal that comprises such apparatus is provided.
