Audio Video Device Interface Matrix List Format Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vision-impaired users find it confusing to navigate two-dimensional matrices on audio video devices, as they cannot visually distinguish rows and columns, leading to disorientation.
Innovation Solution
Implementing a system that allows users to select between a matrix and list format for presenting options on AVDs, where instructions executable by a processor adjust the presentation based on user preference, allowing options to be displayed in a single row or column for one-dimensional navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If options are presented in a matrix format with multiple rows and columns, then navigation speed improves for vision-impaired users, but spatial orientation becomes confusing and disorienting
Solution Approach 1:
The patent transforms the two-dimensional matrix navigation problem into a one-dimensional list structure. By removing the column dimension and organizing all options in a single vertical column, the system eliminates the spatial confusion that arises from two-dimensional navigation while maintaining efficient sequential access to all options through linear scrolling.
2Ease of operation
If options are presented in a list format in a single column, then spatial orientation improves for vision-impaired users, but navigation efficiency decreases compared to matrix format
Solution Approach 1:
The patent implements dynamic reconfiguration of the options display based on user needs. The system can switch between list format (single column) for improved spatial orientation and matrix format (multiple rows and columns) for faster navigation, allowing the interface to adapt its structure dynamically rather than being fixed in one configuration.
3Productivity
If a fixed matrix format is used for presenting options, then navigation speed is improved, but accessibility for vision-impaired users deteriorates
Solution Approach 1:
The patent creates a universal interface system that serves multiple user needs and abilities. By implementing both list and matrix display formats within the same system, the interface becomes adaptable to different user preferences and accessibility requirements, allowing vision-impaired users to choose the format that works best for them while maintaining fast navigation capabilities.

AI summary
A user such as a vision-impaired person watching an audio video device (AVD) such as a TV may be given the option to define, in his user profile, whether he prefers options (such as channel listings on an electronic program guide (EPG)) to be presented in a two-dimensional matrix format or a one-dimensional list format.
