Audio Video Device Quick Accessibility Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Menus for vision- and hearing-impaired accessibility in audio video displays are often buried and non-intuitive, making it difficult for users with impairments to adjust settings, especially when shared with non-impaired users in a common space.
Innovation Solution
A system that uses profiles to simplify user-based settings by correlating users with accessibility settings based on image and vocal recognition, automatically configuring the audio video device with the appropriate settings, and determining user priority when multiple users are present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If accessibility menus are buried under multiple layers of user interface menus, then the display can provide comprehensive accessibility options, but the ease of operation deteriorates for users with visual or hearing impairments
Solution Approach 1:
The system segments user identification and settings configuration into separate, independent modules. User identification occurs through automatic recognition (image/voice), while settings are pre-configured in profiles. This segmentation allows comprehensive accessibility options to exist without requiring users to navigate through complex menu layers to access them.
Solution Approach 2:
Accessibility settings are pre-configured in user profiles before actual use. The system performs preliminary identification of users through image or voice recognition, automatically selecting the appropriate pre-configured accessibility profile. This eliminates the need for users to navigate through multiple menu layers during actual usage.
2Ease of operation
If automatic user identification is implemented, then the ease of operation improves for shared devices, but the device complexity increases due to image and voice recognition systems
Solution Approach 1:
The system introduces an intermediary layer of user profiles that mediates between the complex recognition system and the accessibility settings. The profiles act as a translation layer, mapping recognized user characteristics to pre-configured settings. This intermediary structure simplifies the overall system architecture by separating the complex recognition functionality from the settings application.
Solution Approach 2:
Instead of requiring real-time complex processing for each user interaction, the system creates and stores copies of user profiles with pre-configured accessibility settings. When a user is recognized, the system retrieves the corresponding profile copy rather than processing settings in real-time. This copying approach reduces the computational burden on the recognition system.
3Adaptability or versatility
If priority settings are implemented for multiple users, then the adaptability improves for shared environments, but the ease of operation deteriorates due to additional configuration requirements
Solution Approach 1:
The system implements self-service functionality where users can automatically claim priority through simple image or voice recognition. The system autonomously determines which user should have priority based on pre-set criteria stored in profiles, eliminating the need for manual priority configuration. Users simply need to be recognized, and the system automatically applies the appropriate priority level and accessibility settings.

AI summary
An audio video device (AVD) such as a smart TV allows profiles to be defined on the TV. A user accessing the TV can select one of the profiles to have the TV instantly configure itself for the accessing user. This is useful not only for the hearing-impaired but also visually-impaired people, who may encounter difficulty navigating profile setup menus.
