Keyboard accessible canvas apps?
We are working on an online photobook-editor which runs in a <canvas>.
As you can imagine, this is quite complex, since it may have a huge amount of dynamic interactive elements with several context-menues etc.
Since it has to be WCAG 2.2 compliant, one of the main challenges is, to implement a good and usable keyboard accessibilty.
I know the requirements of standard keyboard accessibility but within a canvas, it's a special case.
I am especially unsure if it's better to navigate inside the canvas with the arrow keys or with the tab or both. And also i want to provide custom context-menues to offer a possibilty to quickly jump to different tool-bars directy from anywhere inside the app without tabbing endlessly.
Does anybody know a good example of a similiar application that is build with canvas and which has a good keyboard accessibility?
Thanks!
