Raising the Dots

About
Welcome and Webinar

Before we get started this month, a reminder to join Dot's June webinar, Developing for Dot Pad X, and discover how innovators across the accessibility community are transforming multiline braille and tactile graphics into practical, engaging applications.


From the AT Guys' browser-based Braille Apps to interactive experiences including chess, checkers, Battleship, Connect 4, calendar tools and more, you'll hear directly from the developers and community leaders bringing these projects to life.
