The Braille Working Group of the European Blind Union hosted a Table Talk webinar to discuss connecting and using Braille displays, with table talk moderator Oleg Shevkun and expert panelists including Ron Miller, Adi Kushnir, Matthew Horspool, and Svetlana Vasilyeva. All panelists participated in the online meeting voluntarily and did not represent their employers; they contributed to the discussion based on their many years of user and professional experience. The discussion focused on the different connection methods between Braille displays and devices, particularly comparing USB and Bluetooth options, as well as the advantages and limitations of HID Braille protocol versus legacy drivers. Panelists shared their experiences with various devices and operating systems, highlighting that while HID Braille offers simpler connections, users still face challenges with device compatibility and screen reader support. The group also discussed troubleshooting tips for connecting Braille displays, with BRLTTY emerging as a potential solution for older devices, though it can sometimes cause conflicts with other screen readers.
Watch The First Table Talk: Connecting the Braille Display, on YouTube channel of Livingbraille
This table talk was the first session of a series on Braille display usage with 96 registrations from 26 countries. Four Table Talks will cover four main topics: connecting, controlling, consuming, and creating with Braille displays. The meeting introduced the Braille Working Group of the European Blind Union and the group’s recent projects, including the Braille 200 initiative and the Living Braille platform.
Braille Technology and Accessibility Insights
The meeting aimed to provide an international perspective on Braille technology and address common challenges faced by users. Braille Working group of EBU introduced panelists with diverse backgrounds in assistive technology and Braille, including Ron Miller, Adi Kushnir, Svetlana Vasilyeva, and Matthew Horspool. Ron shared his experience as the Accessibility Excellence Advocate for the National Federation of the Blind and his move to Maryland. Adi discussed his journey from a Braille user to a developer and seller of Braille technology in Israel. Svetlana highlighted her role as a lead assistive technology specialist and her extensive daily use of Braille. Matthew introduced the Braille Foundation, a UK-based user group, and his work as an assistive technology specialist and trainer. The panelists shared their experiences and expertise in Braille technology, emphasizing the importance of accessibility and innovation in this field.
HID Braille vs Legacy Drivers.
The meeting focused on explaining the differences between HID Braille and legacy drivers for connecting Braille displays to computers. Matthew and Adi clarified that HID Braille allows direct connection without the need for third-party drivers, unlike legacy drivers which require manual installation. They also noted that while HID Braille simplifies the connection process, it doesn’t necessarily guarantee full functionality, as some Braille displays may still require additional drivers for specific protocols. The discussion highlighted the importance of understanding these technical differences for users experiencing connectivity issues with their Braille displays.
Understanding Braille Display Connectivity
Adi explained the differences between HID USB connections and HID Braille protocols, noting that the latter introduces a unified Braille protocol that allows for easier operation of Braille displays with most screen readers. Ron emphasized that while the principle is true, actual execution can vary, and support for different Braille displays and screen readers can differ significantly.
The group discussed the support and configuration of HID Braille connections for various braille displays and operating systems. They noted that newer displays are more likely to have HID Braille enabled by default, while older models may require manual configuration. The discussion covered compatibility across different devices, including Android, iOS, and Windows, with USB and USB-C connections. They also touched on the limitations and advantages of using HID Braille, such as improved compatibility and easier setup for some devices.
Braille Display Driver Discussion
The group discussed the use of HID (Human Interface Device) vs legacy drivers for Braille displays, with Ron and Adi sharing their experiences using HID for simplicity and better screen reader support, and challenges with connecting Braille displays to devices, particularly focusing on USB and Bluetooth connectivity. The discussion highlighted that while Bluetooth connectivity for Braille displays has improved, it can still be more complicated than USB connections, with different behaviors between iOS and Android devices. The conversation concluded with a discussion about driver compatibility issues, particularly for legacy drivers for Braille displays, and the need for “driver hunting” when setting up new devices.
The panellists discussed various solutions for connecting the Braille displays with legacy drivers to Windows computers, with Matthew recommending NVDA and BRLTTY as the most reliable options. Adi explained that BRLTTY can be used on both Windows and Android, though it requires careful configuration to avoid conflicts with other screen readers.

The discussion also covered troubleshooting tips for Bluetooth connectivity issues, with Svetlana and Adi emphasizing the importance of ensuring devices are discoverable and properly configured. Oleg raised a question about Bluetooth stability for note-takers, which led to a discussion about the varying reliability of Bluetooth connections compared to USB.

Conclusion
The meeting focused on discussing the challenges and solutions related to connecting Braille displays to various devices, with an emphasis on Bluetooth and USB connections. Panelists shared their experiences and insights, highlighting the importance of Braille for blind individuals and the need for user-friendly setup processes. The group discussed the potential for manufacturers to simplify the connection process, with Matthew suggesting that improvements might be within reach in the next few years. The next webinar, scheduled for February, will focus on controlling Braille displays across different operating systems, and participants were encouraged to submit questions and suggestions to the panelists and manufacturers.
