Audiofunctions. web: Multimodal exploration of mathematical function graphs
Proceedings of the 16th International Web for All Conference, 2019•dl.acm.org
We present AudioFunctions. web, a web app that uses sonification, earcons and speech
synthesis to enable blind people to explore mathematical function graphs. The system is
designed for personalized access through different interfaces (touchscreen, keyboard,
touchpad and mouse) on both mobile and traditional devices, in order to better adapt to
different user abilities and preferences. It is also publicly available as a web service and can
be directly accessed from the teaching material through a hypertext link. An experimental …

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