We proposed an immersive, more cinematic experience that guides users quite literally through the human circulatory system, detailing the events leading up to, during, and after a heart attack. Through utilizing WebGL, we could build an actual interactive 3D journey that was both more dramatic and informative. Functionality was key to the project that it worked euqally as well across both mobile and desktop platforms with a thoughtful user experience. Collaboration with medical experts was crucial in developing accurate content and realistic 3D models of blood chemistry and physiology. This interdisciplinary effort resulted in an educational tool that not only explains heart health in an engaging manner but also provides a memorable and impactful user experience. The experience needed to be fluid and effortless to navigate in both camera tracking/movements, educational information and a thoughtful usability as well. Between devices, we aimed to make the navigation as intuitive and simple as possible. On the desktop users can glide easily through veins and camera angles by scrolling casually with trackpad (or mouse), and of course with the swipe of a finger on mobile devices. It was a lot of boxes to tick, but resulting in an informative, engaging and dramatic live rendering of a 3D journey to the human heart.
