Television Decoder Assessment With Automated Impaired-User Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing TV set top box interfaces are difficult for impaired users, particularly the elderly, due to lack of dexterity and vision, and there is no objective method to assess their performance effectively.
Innovation Solution
A TV use assessment system comprising a TV decoder, remote control device with simplified buttons, camera, and performance evaluation apparatus that generates an objective performance score based on user interactions, allowing for automated evaluation and comparison.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cursor-based interface or touch screen is used for TV set top box control, then the interface functionality is comprehensive and versatile, but impaired users (especially elderly users) cannot operate it effectively due to lack of dexterity and vision
Solution Approach 1:
The system automatically records user interactions via camera and generates performance scores without requiring manual input from users or therapists. The camera captures button presses and interactions, and the system automatically analyzes this data to assess user performance, eliminating the need for manual assessment while maintaining comprehensive interface functionality
Solution Approach 2:
The patent replaces manual cursor-based navigation and touch screen interaction with a simplified remote control that has large, clearly marked buttons. This mechanical substitution makes the interface accessible to impaired users while the system maintains comprehensive functionality through automatic interaction capture and analysis
2Loss of information
If a camera is used to capture user interactions for assessment, then interaction data can be collected, but the assessment process requires manual review by therapists which is time-consuming and subjective
Solution Approach 1:
The system performs self-assessment by automatically analyzing camera-captured interaction data and generating performance scores without requiring therapist intervention. The performance evaluation apparatus processes the recorded interactions autonomously, eliminating manual review time while preserving complete interaction data
Solution Approach 2:
The system provides immediate automated feedback in the form of performance scores that objectively measure user interaction quality. This feedback mechanism replaces subjective therapist assessment with automated analysis, reducing assessment time while maintaining data completeness
3Adaptability or versatility
If subjective assessment by therapists is used, then personalized evaluation is possible, but objective comparison between users and tracking of improvement over time is difficult
Solution Approach 1:
The system generates standardized performance scores that provide objective, quantifiable feedback on user interactions. These scores enable precise measurement and comparison of user performance across different individuals and time periods, while the system maintains personalized evaluation capabilities through consistent automated assessment criteria
