BigBlueButton Accessibility Features
BigBlueButton offers a variety of accessibility features designed to cater to the needs of all learners, making it an excellent choice for educators and institutions striving to create inclusive virtual classrooms.
BigBlueButton is built with keyboard navigation in mind. Users can navigate menus, buttons, and panels without relying on a mouse, ensuring that individuals with motor impairments or those who prefer keyboard navigation can easily access all features.
Navigating Menus, Buttons, and Panels
BigBlueButton’s interface is designed to be easily navigable using only a keyboard. Users can use the
Tab key to move forward through interactive elements, such as buttons, links, and form fields, and
Shift + Tab to move backward. The
Space key can be used to activate buttons and links.

BigBlueButton also offers keyboard shortcuts for common actions, streamlining the user experience for keyboard users. Some examples include:
Ctrl + Alt + M: Mute/unmute your microphone

Screen Reader Compatibility
BigBlueButton is compatible with various screen reader software, ensuring that visually impaired users can fully participate in virtual classrooms.
Compatible Screen Reader Software
BigBlueButton has been tested and found to be compatible with popular screen reader software like JAWS, NVDA, and VoiceOver. This compatibility ensures that users who rely on screen readers can access all of BigBlueButton’s features and content.
Reading Order and Navigation
The BigBlueButton interface is designed to maintain a logical reading order, making it easy for screen reader users to navigate and understand the content. Additionally, BigBlueButton uses proper headings, landmarks, and ARIA (Accessible Rich Internet Applications) attributes to improve screen reader navigation.
BigBlueButton supports closed captioning for live and recorded sessions, making it an excellent choice for learners with hearing impairments.
Enabling Live Captions
During a live session, a captioner or the presenter can provide real-time captions. To enable this feature, the presenter needs to promote a user to the “Captioner” role. The captioner can then access the closed captioning interface and type captions as the session progresses. These captions will be visible to all users who enable the closed captioning feature.
Adding Captions to Recorded Sessions
For recorded sessions, BigBlueButton allows the addition of captions in VTT format. Once uploaded, captions will be visible to users who enable the closed captioning feature while watching the recorded session.
Customizable Font Sizes and Colors
BigBlueButton offers customizable font sizes and colors, ensuring that the interface is easy to read for individuals with visual impairments or specific color preferences.
Adjusting Text Size
Users can adjust the text size within the BigBlueButton interface according to their preferences. This feature ensures that individuals with visual impairments can comfortably read chat messages, presentations, and other on-screen text.
Choosing High-Contrast Color Schemes
BigBlueButton supports high-contrast color schemes, making it easier for individuals with visual impairments or color blindness to distinguish between interface elements. Users can choose from a variety of color schemes that best suit their needs.
BigBlueButton supports live transcription services, providing real-time text transcriptions for learners who might have difficulty understanding spoken language.
Enabling Automatic Speech Recognition
BigBlueButton can integrate with third-party Automatic Speech Recognition (ASR) services, which can transcribe the presenter’s speech in real-time. This feature provides real-time transcriptions for learners who might have difficulty understanding spoken language due to hearing impairments or other reasons.
Using Third-Party Transcription Services
In addition to ASR, BigBlueButton also supports integration with third-party transcription services, allowing users to choose the service that best suits their needs. Some popular transcription services include Rev, Otter.ai, and Trint.
