Multimodal Exploration of Mathematical Function Graphs with AudioFunctions.web

AudioFunctions.web is a web-based system that enables blind people to explore mathematical function graphs. It uses sonification, earcons and speech synthesis to convey the overall shape of a function graph, its key points of interest, and accurate quantitative information at any given point. The system can be directly linked from digital documents, such as teaching material, and it is designed to be accessed through multiple interfaces such as touchscreen, key-board, touchpad and mouse, on both mobile devices and personal computers. This way, AudioFunctions.web can adapt to different user abilities, preferences and needs.
