Solution Overview

Problem

Visually impaired individuals face challenges in navigating public transportation, particularly in accessing and seating within vehicles, due to lack of effective guidance systems.

Innovation Solution

An AI-powered system in vehicles identifies visually impaired passengers using image data and provides audible instructions through speakers or headsets to guide them to the vehicle entrance and seat, avoiding obstacles and indicating seating options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If visually impaired passengers use public transportation independently, then their quality of life and independence improve, but they face difficulties in navigating and accessing vehicles

Engineering Contradiction:
Improveindependence of visually impaired travelersVSAvoiddifficulty in navigating and accessing vehicles
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces an intermediary system consisting of audio guides, obstacle detectors, and communication devices that mediate between the visually impaired passenger and the physical environment. These intermediaries provide real-time guidance, detect obstacles, and communicate with both the passenger and vehicle operators, enabling independent navigation without visual input.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces visual-mechanical navigation with acoustic and electronic systems. Instead of relying on visual detection and manual navigation, the system uses audio feedback, electronic obstacle detection, and automated communication to guide passengers, substituting the mechanical visual navigation process with electronic sensing and acoustic guidance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If guidance systems are implemented to assist visually impaired passengers, then their ability to access vehicles improves, but system complexity increases

Engineering Contradiction:
Improveability to access vehiclesVSAvoidguidance system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements multi-functional devices that perform multiple roles: communication devices serve both as passenger interfaces and as data transmission nodes; obstacle detectors simultaneously monitor for hazards and provide spatial mapping; audio guides function both as navigation aids and as confirmation mechanisms. This multi-functionality reduces the number of separate components needed.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system incorporates self-service features where the guidance system automatically adjusts its output based on passenger responses, where obstacle detectors continuously update environmental models without manual intervention, and where the system self-calibrates communication protocols. This automation reduces the operational complexity for passengers while maintaining sophisticated functionality.

Inventive Principle:
Principle #25Self-service

3Reliability

If real-time guidance and obstacle detection are provided, then passenger safety improves, but information processing requirements increase

Engineering Contradiction:
Improvepassenger safetyVSAvoidinformation processing requirements
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent divides the information processing task into segments distributed across multiple components: local processors in the guidance device handle immediate navigation data, separate detectors process obstacle information, and communication modules transmit only essential updates. This segmentation allows parallel processing of different data streams, improving safety response times while distributing computational load efficiently.

Inventive Principle:
Principle #1Segmentation

AI summary

Systems and methods for assisting visually impaired passengers, e.g., blind passengers, using rideshare services is provided. The system may identify a visually impaired passenger from image data captured by one or more exterior cameras of a rideshare vehicle, e.g., by detection of use of a cane by the passenger. The system may then generate audible instructions that may be emitted via exterior and interior speakers of the vehicle or via a wirelessly paired headset worn by the passenger, to guide the passenger to the vehicle entrance and to an available passenger seat within the vehicle. The system further may detect obstacles or features in the path of the passenger, and emit audible alerts to guide the passenger around the obstacle or feature.
