I thought I would share the accessibility improvements implemented in the dojox.grid.DataGrid for the 1.3 release. While the DataGrid still doesn't meet all accessibility requirements, it is steadily improving and I hope to be able to claim basic, keyboard, low vision, and assistive technology support in the 1.4 release. Since the grid is a very complicated widget, it may require some tweaks from the browser or assistive technology vendors to achieve full accessibility.

Doug Geoffray, founder of GW Micro the maker of the Window-Eyes screen reader, recently spoke at Yahoo about screen readers. The hour long talk is split into two videos. It gives a brief history and an overview of how screen readers work, some of the problems screen readers need to work around and how to build more accessible products.

Often when I am explaining accessibility requirements for Web pages, I find that people don't really understand the issues concerning High Contrast. This post attempts to explain high contrast mode and includes some pictures to demonstrate the potential problems.
