AudioFunctions.web: Multimodal Exploration of Mathematical Function Graphs

摘要: We present AudioFunctions.web, a web app that uses sonification, earcons and speech synthesis to enable blind people explore mathematical function graphs. The system is designed for personalized access through different interfaces (touchscreen, keyboard, touchpad mouse) on both mobile traditional devices, in order better adapt user abilities preferences. It also publicly available as service can be directly accessed from the teaching material hypertext link. An experimental evaluation with 13 visually impaired participants highlights that, while usability of all presented interaction modalities high, users prefer interact system. shown higher level education are capable adapting considered more difficult by others.
