Location System for Blind Navigation via Support Center
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The blind or visually impaired face challenges in navigating due to their inability to use visual cues like road signs, landmarks, or the sun, and existing navigation systems may not provide adequate assistance, especially for real-time, point-to-point guidance.
Innovation Solution
A location system that includes a wireless communication device, RFID device, GPS, camera, and a database, allowing users to transmit and receive location information via a guidance support center, providing real-time guidance through audio, text, or Braille, and enabling users to request directions or information using a portable device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If GPS and automated voice recognition systems are used, then location information can be provided, but the system cannot provide real-time interactive support for complex navigation queries
Solution Approach 1:
The patent introduces a support center operator as an intermediary between the automated GPS system and the user. The operator receives location data from the GPS device, accesses mapping data, and provides customized navigation instructions through voice communication, bridging the gap between automated data collection and adaptive human guidance.
Solution Approach 2:
The system allows users to initiate service requests independently through their GPS devices. Users can request navigation assistance, location verification, or route information without requiring pre-arranged human support, enabling self-service while maintaining access to human expertise when needed.
2Measurement precision
If multiple devices (GPS, RFID, camera) are integrated, then comprehensive location determination is achieved, but device complexity increases
Solution Approach 1:
The GPS device serves multiple functions: it determines location coordinates, captures images of surroundings, reads RFID tags for point identification, and communicates with the support center. This multi-functionality reduces the need for separate dedicated devices while maintaining comprehensive location determination capabilities.
Solution Approach 2:
The patent combines GPS, RFID reader, and camera functions into an integrated portable device that communicates with a centralized support center. This merging approach consolidates multiple measurement and identification functions into a single user-friendly interface while leveraging specialized services at the support center.
3Adaptability or versatility
If live human support is provided, then complex navigation queries can be answered, but service cost and response time may increase
Solution Approach 1:
The support center operator prepares navigation routes and location information in advance by accessing pre-stored mapping data and point-of-interest databases. This preliminary preparation of route options allows for faster response times when users submit navigation requests, as the operator can quickly select and communicate appropriate routes rather than calculating them in real-time.
