Apple, Microsoft and the USB Implementers Forum (USB-IF) have announced a human interface device (HID) standard for braille displays. This collaboration is huge news for people who are blind or suffering with low vision, as it will make using a braille display across different hardware far, far easier.

The idea is that it removes the need for braille devices to have specially designed software or drivers. This will substantially reduce development time and, hopefully, open up the market. You can find more information in the release.
