Assistive technology does not interact directly with the content displayed in our browsers, or the HTML behind the scenes. Instead it relies on a parallel structure to what we see called the “Accessibility Tree.” This structure is what the browser and assistive technology use to interact with one another. Equipped with a better understanding of the accessibility tree we are better able incorporate accessibility into our work at the onset. This presentation will take a peek under the hood of this technology to understand the process.
Many of us are working to create accessible experiences with little understanding of the process behind the technology we rely on. Some of us may have some awareness of the accessibility tree, or how a browser works, or what a screen reader does. However, how all these pieces are connected to deliver information to users of assistive technology may remain shrouded in mystery. This presentation aims to fill in those blanks with an overview of the process.
- It is important to understand the flow of information from browser to assistive technology.
- Understanding the accessibility tree's key role in this process and how we impact it.
- Applying this knowledge to work of designers and developers can improve the accessibility of web content.
