The Importance of Accessible Design Systems
Summary
A design system is a set of repeatable components and standards guiding the use of those components. Standards can come in the form of documentation, videos, blogs, discussion channels, meetups and office hours just to name a few. A design system may be built internally within an organization, or there are hundreds of open source design systems that can be downloaded and used. However, only a small percentage of those open source design systems are set up such that they can be successfully implemented in a manner that results in software that is accessible to people with disabilities who use assistive technology to interact with technology. This talk will discuss the importance of accessible design systems and a high level overview of the ten best known open source design systems.
