Gemma4 Brings Real-Time ASL Interpretation On-Device

This project demonstrates how general-purpose vision models like Gemma4 can solve specialized accessibility tasks entirely on-device through strategic prompt engineering, eliminating cloud dependency and privacy concerns. By separating hand detection from letter recognition and leveraging precise prompting, the builder achieved strong accuracy without fine-tuning—a pattern that could reshape how we deploy AI for privacy-sensitive applications and accessibility tools.
