我们推出了AudioFunctions.web，这是一款使用发声、耳机和语音合成的网络应用程序，让盲人能够探索数学函数图。该系统设计为通过移动和传统设备上的不同界面(触摸屏、键盘、触摸板和鼠标)进行个性化访问，以更好地适应不同的用户能力和偏好。它也可作为网络服务公开使用，并可通过超文本链接直接从教材中访问。一项对13名视障参与者的实验评估强调，虽然所有呈现的交互模式的可用性都很高，但不同能力的用户更喜欢不同的界面来与系统交互。研究还表明，受过较高数学教育的用户能够更好地适应其他人认为更难的交互方式。
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.
