Probe Sensors for Accessible Path Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems often lack comprehensive data on handicapped or physical disability accessible paths, which are either overlooked in traditional data collection or are not cost-effective to gather, leading to incomplete geographic databases.
Innovation Solution
A method involving probe sensors attached to devices used by individuals with physical disabilities to collect geographic data, which is then transmitted to a data collection facility for incorporation into navigation databases, enhancing the representation of accessible paths and routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional data collection methods are used by map developers, then data collection cost and time are reduced, but data coverage on handicapped accessible paths is insufficient
Solution Approach 1:
The patent enables devices used by individuals with physical disabilities to automatically collect and report geographic data about accessible paths. The system self-services by utilizing the natural movement and usage patterns of these devices to gather data without requiring dedicated map developers to physically traverse and document each accessible path, thereby resolving the contradiction between comprehensive data coverage and collection efficiency
Solution Approach 2:
The patent transforms single-function disability assistance devices into multi-functional tools that simultaneously provide navigation assistance and collect geographic data. By integrating probe sensors into devices like wheelchairs and mobility aids, the system enables these devices to serve both their primary accessibility function and a secondary data collection function, thus improving data coverage without additional dedicated resources
2Measurement precision
If map developers manually collect geographic data, then data accuracy is improved, but time and cost consumption increase
Solution Approach 1:
The patent replaces the mechanical system of manual data collection by map developers with an automated electronic sensing system. Probe sensors integrated into disability assistance devices automatically capture geographic coordinates, path characteristics, and accessibility features, eliminating the need for manual measurement and documentation while maintaining high data accuracy and significantly reducing collection time
3Ease of manufacture
If focus is placed on traditional streets and paths, then data collection cost is reduced, but accessibility path data is lost
Solution Approach 1:
The patent inverts the traditional approach by not actively seeking to document accessible paths through dedicated surveys, but rather by allowing accessible path data to be naturally generated through the usage patterns of disability assistance devices. The system collects data about where these devices actually travel, automatically identifying accessible paths without requiring targeted exploration, thus maintaining low cost while capturing comprehensive accessibility information
Data Source
AI summary
Systems, devices, features, and methods for obtaining, enhancing, or using data for or with a geographic database, such as a navigation database, are disclosed. For example, one method includes receiving input to enable a probe sensor that is associated with a device used by a being with a physical disability. Geographic data is collected via the probe sensor when the device is in use by the being with the physical disability. The collected geographic data is provided to a data collection facility to develop data corresponding to a geographic and/or navigation database.
