IX is Sri Lanka’s first-ever inter-university designathon an event where undergraduates tackle real-world problems through innovative design solutions. Over the years, it has grown into one of the country’s most prestigious UI/UX events. IX 25, organized by the IEEE Student Branch of IIT, marks the fifth wave of Sri Lanka’s pioneering AI and XR Designathon. This edition explores gesture-based spatial interfaces, wearable technology, self-generative UIs, and 3D interactivity. Conducted in two phases, participants first present creative UI/UX concepts, with the top teams advancing to a 36-hour designathon to bring their ideas to life. Evolving beyond a competition, IX has become a platform that nurtures innovation, creativity, and design excellence empowering the next generation to shape the future of digital experiences in Sri Lanka.
