Research and Design of Distributed Voice Guidance System for the Blind
Revolutionizing Independent Mobility for the Visually Impaired
This research proposes and designs a distributed voice guidance system tailored for the blind, addressing the complexities of urban navigation. The system integrates IoT, image recognition, and voice technologies across a guide host, guide hat, and guide cane. Key functionalities include real-time obstacle detection, blind track recognition, target and scene identification, voice-activated control, and audible warnings. The system leverages machine learning models (specifically YOLOv2) trained on custom datasets for high accuracy in recognizing traffic lights and blind pavements. Experimental results demonstrate the system's stability and effectiveness in providing comprehensive assistance for independent travel, though further algorithm optimization is needed for target recognition.

This paper introduces a groundbreaking distributed voice guidance system for the blind, leveraging advanced IoT, AI, and voice technologies. It addresses critical challenges faced by visually impaired individuals in navigating complex urban environments.
Case Study: Voice-Activated Navigation & Warning
Challenge: Blind users face significant challenges operating complex electronic devices while navigating. Traditional systems often require tactile input or pre-programmed routes, limiting real-time adaptability.
Solution: The system integrates the SYN7318 voice recognition and synthesis module, enabling users to issue voice commands for system operation and receive real-time, comprehensive voice guidance and warnings about surroundings, obstacles, and navigation instructions.
Outcome: Improved user independence and safety. Voice control eliminates the need for manual interaction, allowing users to focus on walking. Real-time audio feedback provides critical information, enhancing situational awareness and enabling proactive obstacle avoidance.
