Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for determining accessibility compliance in physical environments are often inaccurate, incomplete, and do not provide actionable recommendations for improvements, leading to potential misuse by individuals with disabilities.
Innovation Solution
An AI-based accessibility feature detection model is trained to analyze images of physical environments, identifying structural features and determining compliance with accessibility guidelines, and provides specific recommendations for modifications or additions to achieve compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If crowdsourced information is used to provide accessibility information for physical environments, then coverage of popular physical environments is improved, but accuracy and completeness of accessibility information deteriorates
Solution Approach 1:
The system enables physical environments to self-report their accessibility features through automated image analysis. The AI model processes images of the physical environment to automatically detect and verify accessibility features, eliminating reliance on manual crowdsourcing while providing accurate, complete information for all environments including those not covered by crowdsourced data.
2Loss of information
If self-reporting by operators is used to provide accessibility information, then information availability is improved, but completeness and accuracy of accessibility information deteriorates
Solution Approach 1:
The system provides automated feedback by analyzing images of the physical environment and comparing detected features against accessibility guidelines. The AI model generates compliance reports that identify missing or non-compliant features, enabling operators to understand gaps in their self-reported information and make targeted improvements to achieve full compliance.
3Loss of information
If conventional accessibility information systems are used, then information provision is improved, but ability to indicate compliance with accessibility guidelines deteriorates
Solution Approach 1:
The system replaces manual assessment of accessibility compliance with automated AI-based image analysis. The machine learning model detects structural features in images and automatically evaluates them against accessibility guidelines, providing objective, accurate compliance determination without relying on subjective manual assessment or incomplete self-reporting.
4Measurement precision
If comprehensive accessibility analysis is performed to ensure accurate compliance determination, then measurement precision is improved, but computational resources and time required deteriorates
Solution Approach 1:
The system performs preliminary action by pre-training the AI model on extensive accessibility guideline data and structural feature patterns before deployment. This pre-training enables the model to quickly and accurately assess compliance during actual use without requiring intensive computational resources for each individual analysis, achieving both high precision and efficiency.
Data Source
AI summary
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining whether a physical environment includes structural features that comply with accessibility guidelines. In one example method, input data, which can include image data representing an image of a particular portion of a physical environment, can be received from a client device. The image data can be input to a trained accessibility feature detection model, which can be trained to detect a particular structural feature and determine whether it meets a first accessibility guideline for the particular structural feature. The data output by the model can be used to determine whether the image data includes the particular structural feature that meets the first accessibility guideline, and based on this determination, an accessibility report can be generated and provided for display on the client device.
