Guide Spectacle with Multi-Modal Sensing for Blind Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assisting the blind, such as walking sticks and guide dogs, are inadequate for navigating complex road conditions and ensuring safety, particularly in emergency situations.
Innovation Solution
A guide spectacle equipped with a signal collecting unit, central processing unit, and functional unit that collects and processes image and voice information to provide navigation and warning functions, enhancing the blind user's ability to safely navigate through complex environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If walking sticks are used to explore road conditions, then basic obstacle detection is achieved, but the system cannot adapt to complicated road conditions and lacks comprehensive safety features
Solution Approach 1:
The guide spectacle integrates multiple functions into a single device: image information collection via camera, voice information collection via microphone, ranging via ultrasonic/infrared/laser modules, positioning via GPS, and audio output via bone conduction earphones. This multi-functional integration enables the system to adapt to various road conditions (pedestrian crossings, obstacles, vehicles, direction finding) while maintaining manageable complexity through unified device architecture.
2Reliability
If guide dogs are used for assistance, then navigation support is provided, but the dogs may be frightened in emergencies and threaten safety
Solution Approach 1:
The patent replaces the biological guide dog system with an electronic and optical system. The camera captures visual information, the central processing unit analyzes road conditions and detects emergencies, and the bone conduction earphones provide real-time audio guidance. This substitution eliminates the emotional and physiological limitations of guide dogs (fear responses in emergencies) while providing more reliable and consistent safety assistance through automated electronic detection and response systems.
3Loss of information
If multiple sensing units are integrated in the guide spectacle, then comprehensive environmental information is collected, but the device complexity increases
Solution Approach 1:
The patent merges multiple sensing units (camera for image information, microphone for voice information, ultrasonic/infrared/laser ranging modules for distance measurement, GPS for positioning) into a single integrated guide spectacle device. All these units connect to a central processing unit that coordinates their operations and integrates their data outputs. This merging approach enables comprehensive environmental information collection while managing device complexity through unified architecture and centralized processing.
