Speech-Controlled Power Lenses for Optical Wearables: A Hands-Free Solution for Focus Adjustment

This paper presents a system for speech-controlled optical wearables that dynamically adjust lens focus through motorized control. The system integrates the AI Thinker VCO2 module for offline voice recognition and the ESP32 microcontroller for motor control. The system provides users with hands-free control to adjust lens focus using natural language commands such as ’Zoom In’ or ’Zoom Out’. We analyze the architecture, process flow, and mathematical models that govern motor control and evaluate performance based on real-world testing. Experimental results demonstrate the system’s feasibility in various environmental conditions.
