Accessible, Multimodal Charts and Graphs on Touchscreens

Date & Time
Friday, March 22, 2024 - 4:20 PM PDT  
Grand GH  

Charts, graphs, and visual representations are a key component of representing data. This is particularly true in science, technology, engineering, and math (STEM) disciplines, where visual graphics dominate the way information is shared and understood. Yet, access to these graphics - particularly nonvisually - is a growing challenge, exacerbated by the increase in adoption of highly visual, digital mediums as a primary mode of information sharing. Touchscreens, which are widely available and adopted within the blindness and low vision community, have the potential to close the gap in accessible, digital graphics. Touchscreens provide a unique, multimodal experience, offering the ability to render graphics with sound, text description, vibration, and magnified visuals - all from one platform. In our ongoing collaborative research, we have investigated the presentation of digital STEM graphics rendered on touchscreens, highlighting both the affordances and limitations of this approach in facilitating graphical information access, compared to current and best practices.

In this session, we will review our current and previous research and will share recent findings on how to create more complex charts, such as those found in statistics (e.g. histograms and scatter plots). We will demonstrate a new approach using spatial audio to support localization, in addition to structured navigation using gestures. We will end with an interactive discussion on future development efforts.
