Content-Based Voice Output for Display Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice output functions in display apparatuses for visually impaired individuals are not optimized for practical user experience, focusing more on meeting regional standards rather than enhancing usability.
Innovation Solution
A content-based voice output method and apparatus that allows users to select and navigate items through a user interface, providing real-time voice content and explanations, and managing voice output for audio and video playback progress, improving user interaction and reducing unnecessary operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the voice output function follows regional standards, then compliance is achieved, but user experience is not optimized
Solution Approach 1:
The patent changes the parameters of voice output by introducing content-based differentiation (reading speed, pause duration, explanation depth) rather than following fixed regional standards. This allows the system to adapt voice output parameters to actual content characteristics and user needs, improving user experience while maintaining compliance.
Solution Approach 2:
The system dynamically adjusts voice output based on content type, user interactions, and contextual information. Rather than static standard-compliant output, the voice output adapts in real-time to user needs, such as providing explanations upon request or adjusting reading speed based on content complexity.
2Ease of operation
If the selector moves to select different items via user input, then navigation capability is provided, but interaction complexity increases
Solution Approach 1:
The system provides immediate voice feedback when the selector moves to a new item, announcing the item name or description. This feedback mechanism reduces interaction complexity by confirming navigation status without requiring additional user actions, making the navigation process more intuitive and easier to operate.
Solution Approach 2:
The voice output system automatically announces item information when the selector moves, without requiring the user to initiate separate commands. The system serves itself by detecting selector position changes and autonomously providing voice announcements, reducing the burden on the user.
3Loss of information
If explanation voice is provided for voice content, then information completeness is improved, but output time increases
Solution Approach 1:
The system prepares explanation content in advance based on the type of information being presented. For commonly requested explanations or important content, the explanation voice is pre-loaded or pre-processed, allowing for faster delivery when the user requests it, thus reducing the perceived output time while maintaining information completeness.
Solution Approach 2:
The explanation voice is provided periodically or on-demand rather than continuously. The system waits for user requests (such as pressing a button or voice command) before delivering explanations, allowing users to control the pace of information delivery and reducing total output time while ensuring complete information is available when needed.

AI summary
Disclosed is a content-based voice output method, including: displaying a user interface comprising at least one item and a selector for indicating that an item is selected; in response to a first instruction, causing the selector to move from a first item to a second item, and playing voice content corresponding to the second item; and in response to a second instruction, playing a first explanation voice related to the voice content.
