Day 2 of dashboard week was all about accessibility and the challenge I was given was to make a tableau dashboard be usable by someone who uses a screen reader. As the dashboard they had was not able to do this.
When I first uploaded the dashboard onto tableau server and used a screen reader it was only reading the sheet titles and not anything being visualised. After doing some research I found out this was because screen readers cannot read a lot of things on a dashboard.
After this I realised that all KPIs and important information needed to be in the sheet titles, for those using screen readers and being visualised for those that don’t use them. This made me think to use dynamic titles for each sheet and then hide them if they were a KPI so the same information would not be being said twice for those without screen readers.
And then when it came to the title of the dashboard itself it was not reading it when it was just a text box so I had to also add that as a sheet title on a blank sheet. Which was made with a calculated field.
This challenge was extremely eye opening as it is something I knew was an issue but I have never thought about implementing accessibility options when designing a dashboard.
