Process

  1. Plan accessible workshops

    Designed co-design sessions for 9 participants using visual and non-verbal methods suited to their communication needs.

  2. Run co-design and testing

    Combined generative methods (interviews and co-design) with evaluative methods (usability testing) across workshops.

  3. Collect ratings and surveys

    Gathered survey and rating data alongside qualitative observations.

  4. Synthesise

    Used journey mapping and Framework Analysis to turn co-design data into clear findings and accessibility barriers.

  5. Share

    Presented through workshops, conference talks and journal papers, and maintain the project website.

The question

Data visualisation is everywhere, from health information to news, but most design guidance assumes readers can easily process text-heavy labels, legends and explanations. This project explores how people with aphasia and developmental language disorder (DLD) experience data visualisation, and what would make charts work better for them.

Approach

Working with colleagues in an interdisciplinary team, I set up and run workshops where participants co-design visualisation approaches with us. Methods are adapted to participants' communication needs, relying on visual and non-verbal techniques rather than long verbal explanations.
