Compatible 2D Table Navigation System for Visually Impaired Users

Complex data comprehension is a hard task for visually impaired people, for the lack of viable supporting tools. We designed a web-based interactive navigation system to enable visually impaired people to effectively explore a simple data table on common touch devices. Due to ecological factor, there are still many blind people who are not used to complex structured dataset. Thus we made user interactions consistent with major mobile screen readers to minimize the users' burden. Users can easily overview and query detailed information while optimizing the cognitive workload.
