交互式模拟在科学教育中越来越重要，但大多数是盲人学习者无法访问的。我们演示了一个可访问的版本的模拟，crafons和静电，说明响应提供屏幕阅读器支持的关键挑战：需要描述不可预测的事件序列，操作的对象，作为控制和显示，以及管理的描述的变化的状态的模拟以及状态的交互式对象，本身。要应对这些挑战，就需要扩展当前的视觉交互式内容的口头描述实践。
Interactive simulations are increasingly important in science education, yet most are inaccessible to blind learners. We demonstrate an accessible version of a simulation, Balloons and Static Electricity, that illustrates responses to key challenges in providing screen reader support: the need to describe unpredictable sequences of events, the manipulation of objects that act as both controls and displays, and the management of descriptions of changes in the state of the simulation as well as of the state of the interactive object, itself. Meeting these challenges requires extending current practices for verbal description of visual interactive content.
