Simplifying Accessible Data Visualizations

Date & Time
Thursday, March 21, 2024 - 2:20 PM PDT

Highcharts and Elsevier share recent research into making interactive web charts more accessible. Our usability studies focused on improving intelligibility and understandability of non-visual user experiences of graphs and charts. We will share findings around the design of use case-based text descriptions and personalized charts.

When we started our research into screen reader friendly charts eight years ago, we challenged the notion that a table version of the data was an equivalent and sufficiently accessible alternative. Since then, we’ve explored many features such as automated data point and structure descriptions, human created descriptions, and sonification or tones.

We will share our research into examining different information seeking modes or use cases. What is the ideal user experience for use cases of: data point examination, identification of trends, and main idea extraction? Based upon these modes we will propose optimal designs for accessible data visualization consumption.

With each of the new accessibility research questions we will provide real user feedback from non-sighted users on our approach. We will also show screen reader demos to help illustrate design considerations.
