Synchronized Braille and Voice Output for Visually Impaired Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned devices primarily designed for non-disabled and younger users pose barriers for visually impaired and elderly individuals, as they often provide braille and voice information independently, making it difficult for visually impaired users to access and understand information efficiently.
Innovation Solution
An apparatus and method that link braille and voice information by analyzing a user's reading pattern to synchronize voice output with braille reading, adjusting timing, compression level, and speed based on reading completion and speed data, ensuring that voice information is provided in a synchronized and accessible manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If braille information and voice information are provided independently, then the information can be delivered to visually impaired users, but the users cannot obtain information efficiently due to lack of synchronization
Solution Approach 1:
The patent combines braille information and voice information into a synchronized output system. The control unit coordinates the timing of braille display updates with voice output, merging two independent information channels into a unified accessible interface that maintains synchronization between tactile and auditory feedback.
Solution Approach 2:
The system monitors the user's reading progress of braille information and uses this feedback to dynamically adjust voice output timing. By detecting when the user has read certain braille content, the system provides corresponding voice information at appropriate moments, creating a responsive feedback loop that enhances information delivery efficiency.
2Adaptability or versatility
If unmanned devices are introduced to replace service workers, then service coverage expands, but accessibility for visually impaired users deteriorates due to lack of specialized support
Solution Approach 1:
The unmanned device incorporates multiple output modalities (braille display and voice output) within a single system, enabling it to serve diverse user needs. The device can operate in different modes depending on user requirements, providing tactile feedback, auditory feedback, or both simultaneously, thus maintaining universal accessibility while expanding service coverage.
3Adaptability or versatility
If reading speed varies among users, then individual reading preferences exist, but standardized voice output timing becomes ineffective
Solution Approach 1:
The system dynamically adjusts voice output timing based on detected reading patterns. By monitoring how quickly users read braille information, the system adapts its voice delivery speed and timing accordingly, transforming from a static standardized output to a dynamic responsive system that optimizes information delivery efficiency for each user's reading pace.
