Cover Story: Our study presents an interactive American Sign Language (ASL) learning platform that combines real-time ASL sign recognition with gamified vocabulary practice to create a more accessible educational experience for Deaf and Hard-of-Hearing (HoH) learners. We developed a browser-based system that integrates webcam-driven ASL recognition, a lightweight transformer-based machine learning model, and an adaptive word-search game, transforming passive learning into active engagement. The system allows learners to enter words by signing and reinforces vocabulary through gameplay. Our platform bridges computer vision, accessibility, and educational technology. The results demonstrate strong technical performance and positive learning outcomes, highlighting the potential of AI-driven, gesture-based educational tools for inclusive language learning. View this paper
