There is a wide selection of typefaces available on ArcGIS Online. However, I would like to propose that the Atkinson Hyperlegible typeface is added to the collection. Not just the map viewer, but for all apps where fonts can be configured.
It would give us the ability to provide even more accessible experiences to our users.
As described on the Braille Institute’s website:
At Braille Institute, we’ve created a family of hyperlegible® fonts designed to improve legibility and readability for individuals with low vision. These carefully crafted fonts feature clear, highly distinctive letters and numbers that make reading easier and more accessible. Our award-winning font has made reading easier for millions upon millions of people and continues to change lives daily. Good news, it’s free for everyone—from personal use to all commercial applications. Start reading with ease today!
