Animations On or Off

Animations are ON by default in the Tuva Tools to give learners dynamic visual feedback and help them draw connections between the different graphical representations of the data. Since animated data points and graphs can potentially cause seizures, learners have the ability to go to the ACCESSIBILITY CARD and turn off Animations.

Data Colors for Colorblindness

Tuva’s Data Exploration Tool includes descriptive and contextual ARIA labels across the different cards, toolbar menu, and plotting area to ensure people with low vision and blindness can analyze data.

Sonification (beta)

Tuva’s Data Exploration Tool has a proof of concept sonification system. Sonification will create an auditory representation of the visual data shown in the plotting area. While this feature is in beta, it’s been released for use so we may receive feedback and perform research about how the Tools should represent visual data as auditory output.
