Capability-Specific Routing for Accessible Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with special needs face difficulties in determining accessible facilities and routes in unfamiliar areas, particularly in areas with older infrastructure that lacks ADA compliance, making it challenging to navigate safely and efficiently.
Innovation Solution
A system comprising a mapping apparatus with a storage unit and processing unit that utilizes a database to provide accessibility information, allowing users to input their capabilities and receive compatible facility and route recommendations, including graphical, Braille, and audible outputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional mapping applications are used, then general navigation information is provided, but accessibility-specific route information is insufficient
Solution Approach 1:
The patent applies local quality by providing accessibility-specific information for particular locations and route segments rather than generic navigation data. The system identifies and highlights specific areas with accessibility features (curb cuts, ramps, accessible restrooms) and marks inaccessible areas, allowing users to make informed decisions about accessibility compatibility at each location along the route.
Solution Approach 2:
The patent introduces an intermediary layer between general mapping data and user needs by implementing a capability indicator system. This intermediary translates user-specific accessibility requirements into actionable route recommendations, filtering and prioritizing information based on individual capabilities to present relevant accessibility information without overwhelming the user with unnecessary data.
2Reliability
If detailed accessibility information is provided for all facilities, then accessibility compatibility is improved, but information overload occurs
Solution Approach 1:
The patent segments accessibility information into discrete, manageable categories such as curb cuts, ramps, accessible restrooms, and audible signals. Each facility and route segment is evaluated against these specific criteria, allowing the system to present detailed accessibility information in an organized manner that is easy to process and understand without overwhelming the user.
Solution Approach 2:
The patent applies partial action by providing detailed accessibility information only for facilities and route segments that are relevant to the user's specific capabilities and travel needs. Rather than presenting comprehensive accessibility data for all possible locations, the system selectively displays information based on the user's indicated requirements, reducing information overload while maintaining reliability for critical accessibility determinations.
3Ease of operation
If capability indicators are collected from users, then personalized route recommendations are improved, but user input requirements increase
Solution Approach 1:
The patent implements self-service by allowing users to indicate their capabilities through simple capability indicators that automatically trigger personalized route recommendations. The system uses these indicators to autonomously filter and select appropriate routes without requiring users to manually provide detailed accessibility requirements or receive extensive personalized information, thus reducing user input time while maintaining ease of operation.
Data Source
AI summary
A method is provided for performing capability-specific routing. The method includes receiving location information specifying a location. At least one capability indicator representative of user capabilities is also received. A database is accessed, the database specifying, based on user capabilities, facilities that can be accessed by a user, as well as respective geographic locations of specified facilities. A determination is then made as to the facilities that are associated with the received location that are compatible with the received capability indicator. Position information specifying a position may also be received, and at least one route may be determined between the location and the position, the route being compatible with the capability indicator. An apparatus and a computer program product are also provided.
