Braille Scene Translation via Structured Image Description
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack effective methods to translate visual scenes from digital images into braille for visually impaired individuals, failing to provide accurate and relevant tactile information in a user-friendly manner.
Innovation Solution
A system comprising a translation controller and a braille sequence printer that generates structured descriptions of scenes from digital images, using image recognition techniques to identify features and details, and converts them into braille text, allowing for user prompts to retrieve additional information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a digital image is translated directly to braille without structured description, then the translation process is simple, but the accuracy and relevance of tactile information is poor
Solution Approach 1:
The patent segments the translation process into distinct stages: image capture, structured description generation through image recognition, and braille translation. This segmentation allows each component to specialize in one function, improving overall translation accuracy while managing system complexity through modular architecture.
Solution Approach 2:
The patent introduces a structured description as an intermediary layer between the digital image and the braille output. This intermediary structure organizes visual information into meaningful categories and relationships, enabling accurate braille translation without requiring direct complex image-to-braille mapping.
2Loss of information
If all scene details are translated to braille simultaneously, then complete information is provided, but the usability and user-friendliness decreases
Solution Approach 1:
The patent segments braille output into primary scene overview and secondary detailed information. Users receive a manageable summary first, then can access additional details as needed, maintaining information completeness while improving ease of operation through progressive disclosure.
Solution Approach 2:
The patent implements dynamic braille output that adapts to user needs. The system provides different levels of detail based on user interaction, allowing the information delivery to be flexible and responsive rather than static and overwhelming.
3Loss of information
If image recognition techniques are used to generate structured descriptions, then relevant tactile information is improved, but the processing time increases
Solution Approach 1:
The patent performs preliminary image recognition and structured description generation before braille translation. By preparing the structured description in advance, the system reduces real-time processing requirements during actual translation, balancing information quality with processing time.
Solution Approach 2:
The patent implements partial processing where only the most relevant scene features are fully processed into structured descriptions, while less critical elements receive simplified treatment. This selective approach maintains adequate tactile information quality while reducing overall processing time.

AI summary
A structured description is generated for a digital image of a scene. The structured description may include a first feature and a second feature of the scene. The structured description may also include a first detail of the first feature and a second detail of the second feature. A portable braille sequence printer may generate braille text of the first and second features using the structured description. The portable braille sequence printer may further generate additional braille text regarding the first detail in response to a prompt from the user regarding the first feature.
