Parallel DOM Architecture for Accessible Interactive Simulations

摘要: Interactive simulations are used in classrooms around the world to support student learning. Creating accessible interactive is a complex challenge that pushes boundaries of current accessibility approaches and standards. In this work, we present new approach addressing needs within interactives. Within custom scene graph utilizes model-view-controller architectural pattern, utilize parallel document object model (PDOM) create (PhET Simulations) students through alternative input devices descriptions accessed with screen reader software. paper, describe our goals, challenges, creating robust simulations, provide examples from an simulation have developed possibilities for future extensions.
