Per a press release from the USB Implementers Forum (USB-IF):
USB Implementers Forum (USB-IF), the support organization for the advancement and adoption of USB technology, today announced a USB HID (Human Interface Device) standard for braille displays, representing a collaborative step toward greater technological accessibility for people who are blind or have low vision. The standard will make it easier to use a braille display across operating systems and different types of hardware. It will also simplify development, removing the need for braille devices to have custom software and drivers created for a particular operating system or screen reader.
“This is another great example of how USB-IF device class specifications can improve people’s lives,” said USB-IF President and COO Jeff Ravencraft. “With more than 1000 members worldwide, USB-IF brings companies together to improve access to technology and provide a seamless user experience.”
This is a positive development, with a push from Apple. The company's Senior Director of Global Accessibility Policy & Initiatives, Sarah Herrlinger, said in part, “We’re proud to advance this new USB-IF standard because we believe in improving the experience for all people who rely on braille displays to use their Apple products or any other device.”
