Utilizing custom YOLO and MobileNet models trained via Roboflow and deployed via TensorFlow Lite on Android/UVC hardware, it detects real-time environmental obstacles and translates them into instant spoken audio warnings for visually impaired users—requiring zero cloud latency or internet connectivity.</p> <h2> Demo </h2> <p><a href="https://github.com/BuhariSalisuAI/VISION-LINK-AI-" rel="noopener noreferrer">https://github.com/BuhariSalisuAI/VISION-LINK-AI-</a></p> <h2> Code </h2> <p>Check out our core repository and mobile implementation on GitHub: <a href="https://github.com/BuhariSalisuAI/VISION-LINK-AI-" rel="noopener noreferrer">https://github.com/BuhariSalisuAI/VISION-LINK-AI-</a></p> <h2> How I Built It </h2> <p>We built Vision-Link AI Hub using open-weight models (SSD MobileNet / YOLO), TensorFlow Lite for on-device Android inference, and UVC camera integration. By keeping inference completely on the edge, the device operates seamlessly in airplane mode, ensuring user privacy and instant response times under 100ms.</p> <h2> Why Does Open Innovation Matter? </h2> <p>Open innovation and open-weight models allow developers to deploy life-changing assistive technologies directly to local hardware without depending on costly cloud APIs or stable internet connections. For visually impaired individuals in developing regions, offline capability is not just a feature—it is a necessity for safety and independence.</p> <h2> My Agent Session </h2> <p>Developed with the assistance of advanced AI coding workflows, optimizing our TFLite Android integration and edge-AI pipeline.</p> <h2> The Spirit of It </h2> <p>Building Vision-Link AI Hub was driven by a deep passion to give sight through sound. Knowing that a visually impaired person can walk independently, avoid obstacles safely, and hear instant real-time audio warnings without needing an internet connection brings life-changing impact to reality.</p> <h2> Prize Categories </h2> <p>Open Source AI, Healthcare &amp; Assistive Technology, Edge Computing.</p> devchallenge hf26challenge
